For Houston homeowners, the choice usually comes down to the “big three”: PEX, copper, and PVC.

So, if you have to have your home re-piped, a process that entails replacing all of the water supply lines in and around your home, how do you know which pipe material is the best fit for you? 

We’re going to break down the differences in quality, durability, cost, and everyday use so you can make a more confident decision when the pipe replacement becomes necessary.

Which Is Best: PEX, Copper, or PVC Pipes (The Quick Answer)?

Most people want a simple answer when they ask about direct comparisons of PEX vs. copper vs. PVC pipes, but the answers aren’t always straightforward. Each type of pipe material has its own lane. PEX is flexible, easy to install, making it the budget-friendly option; copper is rugged and built for the long haul, and PVC handles the drains without incurring significant costs. Which one is “best” depends less on the material used and more on what role the pipe needs to play in your plumbing system.

Understanding the Differences Between PEX, Copper, and PVC.

Let’s start with PEX, also known as cross-linked polyethylene. It’s a flexible plastic tubing that bends around corners and threads through walls with far fewer fittings than rigid copper or PVC. That flexibility makes installation faster and less invasive — a massive plus in new home builds and remodels. PEX is also more forgiving during cold snaps, as it can expand and contract without cracking. 

The downside is that PEX can’t be left in direct sunlight and can be vulnerable to the teeth of thirsty rodents trying to access the water contained inside the pipe.

Copper plumbing has been around long enough to establish itself as the preferred material for new plumbing lines. Like a superhero, it endures the unrelenting Houston summer heat without breaking a sweat, shrugs off sunlight, and even kills any bacteria that are unlucky enough to find their way to your copper pipes.  

A well-installed copper system can keep everything flowing for half a century or more, and when it’s finally time to replace your old copper lines, your old copper pipes can be recycled. But there’s a catch! Copper isn’t cheap, and installing it requires a licensed plumbing technician who has the necessary tools and experience to do the job correctly.

PVC, or polyvinyl chloride, is the lightest and cheapest of the three. Its smooth interior makes it perfect for drains and vents, in places where you want wastewater to move quickly without buildup. It’s also easy to cut and fit, which is why you’ll see it in so many home and commercial drain systems. But PVC has its limits — it can’t carry hot water, and it becomes brittle with age or prolonged sun exposure.

How Long Do PEX, Copper, and PVC Pipes Last?

Durability is crucial when you decide to start making substantial improvements to your home’s plumbing system.

So, when it comes to overall longevity and reliability, copper always emerges as the undisputed champion in terms of expected lifespans, as it is known to last at least half a century. Notably, many of the older homes in historic districts, such as Montrose or the Heights, still have—and utilize—the original copper supply lines, galvanized steel drain pipes, and sewer lines that were installed when these homes were built in the 1920s and 1930s! 

PEX comes in second, with a potential lifespan of 25 to 50 years, depending on the quality of the material, proper installation, and the type of exposure the pipes are subjected to, such as direct sunlight and high heat, as well as the quality of the fittings used. 

PVC holds up well in drain systems for 25 to 40 years, but it isn’t designed for pressurized use, such as in hot or cold water supply lines, limiting its use in supply plumbing.

In short, if you’re looking for pipes that can outlast your time in the house, and maybe even outlive the house, then copper is the way to go. If you’re looking for something dependable but more affordable, PEX strikes a good balance between cost and longevity. PVC is inexpensive and is perfect for use in drain and sewer lines. 

What Are the Pros and Cons of Each Pipe Type?

Every pipe material comes with trade-offs.

• PEX shines for its flexibility and affordability, as it’s easy to install, resists freezing better than any rigid pipe, and is excellent for retrofits. On the downside, it’s not rodent-proof, doesn’t tolerate sunlight, and if any sections of the pipe become kinked, they will need to be replaced.
• Copper’s strengths are legendary: extreme durability, tolerance for high heat, and a lifespan that can stretch into a century. It also adds a measure of water purity thanks to its antibacterial properties. However, copper’s price tag is steep, and in areas with acidic water, it can corrode and develop pinhole leaks unless a whole-house water filtration system is installed.
• PVC, meanwhile, is the budget option that gets the job done for drains, waste, and vent systems. It’s light, easy to work with, and utterly resistant to rust. The drawbacks are its inability to handle hot water and its tendency to grow brittle when exposed to the elements.

Which Pipes Work Best for My Houston Home?

Houston presents its own plumbing challenges. Our humid climate, shifting clay soil, and mineral-rich water can all take a toll on pipes. That’s why many local homes use a combination of materials. PEX often carries hot and cold water through the house. PVC is used for drain, waste, and vent lines. Copper is used in hot water systems or in outdoor applications where sunlight would otherwise damage PEX.

In other words, there isn’t one single “best” pipe for Houston — the right choice often depends on where the pipe is going and what job it needs to do.

How Much Does It Cost to Replace Plumbing Pipes in Houston?

The cost of repiping a home varies widely depending on the material and the scale of the job. PEX is usually the least expensive, both because the tubing itself costs less and because installation is faster. 

PVC is cheaper per foot than either PEX or copper, but since it’s only used in drain systems, it won’t be part of a whole-house water supply-line replacement. Copper is the most expensive option, often two to three times the cost of PEX, primarily due to labor costs.

When weighing the cost, it’s worth remembering that a higher upfront investment in copper may provide decades of service. At the same time, PEX offers a lower entry price and still provides plenty of reliability for most households.

Can I Install or Replace Pipes on My Own?

PEX and PVC are sometimes marketed as DIY-friendly. PEX’s push-fit fittings and PVC’s simple cuts and glue joints make small projects — like running a short drain line or replacing a section of supply pipe — feel manageable. But for whole-house repipes or major upgrades, it’s best to call a licensed plumber for pipe replacement. A professional will ensure your system meets Houston’s building codes and avoid costly mistakes that could cause leaks, water damage, or worse.

FAQ’s About Replacing Plumbing Pipes in Houston:

Is PEX safe for drinking water?

Yes. When certified for use with potable water, PEX is a safe and widely installed material in new homes.

Which pipe is best for hot water lines in a home?

Copper is the most durable choice for hot water, though PEX also performs well and is easier to install. PVC should never be used for hot water.

Why is copper plumbing more expensive than PEX?

Copper costs more as a raw material, and installing it requires more labor and skill. That combination makes it the priciest option upfront.

Knowing how to read the signs can make the difference between a quick electric water heater repair and waking up to a full-blown replacement job. Let’s walk through the most common red flags, how to tell what they mean, and when it might be time to swap your old system for a new one.

Why Houston Homeowners Need to Watch Their Electric Water Heaters.

Houston’s hot and humid climate is harsh on appliances. Between our mineral-heavy water supply and constant seasonal use, water heaters in the city tend to wear down more quickly than expected. Traditional electric units are built to last 8–12 years, but that number shrinks fast if sediment collects at the bottom of the tank or if routine maintenance gets skipped.

The good news? Paying attention to the early warning signs can help you stay ahead of breakdowns. It’s usually cheaper to repair a minor issue before it spirals into a bigger one.

How Do I Know If My Electric Water Heater Needs Repair?

One of the most apparent signs of a bad water heater is a shortage of hot water. Maybe your showers aren’t lasting as long, or you’re running out of hot water halfway through a load of laundry. If your water heater is not heating water the way it used to, a failing heating element or thermostat could be the culprit. These are parts a licensed plumber can often replace without too much trouble.

Another clue is water pressure. If you’ve noticed a gradual decline in hot water pressure, sediment may be clogging the tank or pipes. A professional flush can often restore normal flow.

And don’t ignore discoloration. Rusty, brownish water is often a sign that the tank’s interior is corroding. Sometimes it’s just the anode rod — a part designed to rust so the tank doesn’t — which can be swapped out. But if the rust has spread inside the tank walls, electric water heater replacement is usually the only option.

Should I Repair or Replace My Electric Water Heater?

This is the big question: how do you know when to replace an electric water heater instead of repairing it again? A few rules of thumb help guide the decision.

• Age: If your unit is 10 years or older, replacement often makes more sense. Even if you fix one issue, another may be just around the corner.
• Frequency of repairs: Needing a technician every few months is usually a sign it’s time to move on.
• Tank condition: Leaks from the tank itself are not repairable. Once the steel starts to fail, there’s no patch strong enough to hold back the water.

Repairs make sense when the problem is isolated — like a bad thermostat, a faulty heating element, or a leaky valve. Replacement makes sense when the issues are frequent, costly, or tied to the tank itself.

Why Is My Electric Water Heater Making Strange Noises?

If you hear banging, popping, or hissing sounds from the tank, it’s not your imagination. These strange noises from a water heater are almost always linked to sediment buildup. Over time, minerals settle at the bottom of the tank and harden. When the heating element tries to warm the water trapped inside that sediment, it makes noise — and wastes energy.

Sometimes a good flush clears out the sediment and quiets the tank. But if the noise persists or the tank has never been serviced, the damage may already be done. Left unchecked, sediment buildup makes your system less efficient and shortens its lifespan.

What Happens If My Water Heater Is Leaking?

A leaking electric water heater is never a good sign. If the water is coming from a pipe fitting or the pressure relief valve, a repair may do the trick. Tightening a connection or replacing a valve is relatively straightforward.

If the water is pooling under the tank itself, though, that’s bad news. Leaks from the bottom usually mean the metal has corroded. Unfortunately, once the tank wall is compromised, the only safe solution is replacement. Putting it off risks a sudden rupture — and a flood you definitely don’t want in your garage or utility closet.

Benefits of Booking With Nick’s Professional Plumbers.

Water heaters rarely fail at convenient times. That’s where having a trusted local team makes all the difference. At Nick’s Plumbing & Air Conditioning, our licensed technicians have seen it all — from elements that fizzle out to tanks that have completely rusted through.

When you call Nick’s, you’re not just getting a repair or installation. You’re also getting a complete assessment of your system, so you know whether repair or replacement is the better move. We’ll explain your options, help you plan around your budget, and make sure the job’s done right the first time.

Don’t Wait for Cold Showers—Fix Water Heater Problems Early

An electric water heater won’t usually quit overnight. It gives you hints — shorter showers, new noises, little leaks — long before it fails. Paying attention to these signs of a bad water heater helps you avoid emergencies and gives you time to plan for a repair or replacement.

Whether it’s a thermostat swap, a tank flush, or a brand-new installation, the key is not waiting until your morning shower turns into a cold plunge!

 While some of this can be chalked up to age or usage, much of the problem has one root cause — the extremely hard water we have in Houston.

Let’s break down why Houston homes struggle with hard water, how it affects your plumbing fixtures, and what you can do to protect your system from long-term damage.

Why Houston Homes Struggle with Hard Water

So, does Houston have hard water? The answer is yes. Our city’s water supply comes from a mix of surface water (like lakes and reservoirs) and groundwater, both of which carry dissolved minerals. By the time the water reaches your tap, it often contains high levels of magnesium and especially calcium.

On average, Houston water tests around 7.9–8.0 grains per gallon — that’s considered “moderately hard” to “very hard.” Over time, those minerals don’t just flow through your plumbing. They stick, layer up, and create what most homeowners recognize as the chalky, white buildup around fixtures.

How Hard Water Damages Plumbing Fixtures

The real problem with hard water damage plumbing systems is that the minerals never stop moving through your pipes. They leave behind scale that coats everything it touches — pipes, faucets, showerheads, and even the seals inside your fixtures.

That limescale buildup does more than look bad. It clogs aerators, reduces water pressure, and accelerates fixture wear. Over time, mineral deposits can corrode metal, crack seals, and cause leaks in hard-to-reach areas. That’s why plumbing fixtures in Houston often need to be replaced long before their expected lifespan.

Why Do My Faucets and Showerheads Develop That White Buildup So Fast?

If you’ve noticed your faucet losing its shine or your showerhead sputtering after only a few months, you’re not imagining it. That chalky white crust is limescale, left behind when Houston’s hard water evaporates. The minerals don’t go anywhere — they just stick around. Over time, they accumulate around the edges of faucets, inside aerators, and in the small nozzles of your showerhead. Anywhere water sits or drips regularly is a prime target, which is why the buildup seems to show up faster there than anywhere else.

So, if you’ve ever wondered why faucets corrode quickly or why your showerhead clogs after just a few months, you’re looking at the work of limescale. As water evaporates from those surfaces, the minerals stay behind, leaving a crusty white ring. In areas where water sits (like inside the showerhead or at the tip of a faucet), the buildup happens even faster.

This mineral buildup in faucets doesn’t just make them look bad — it reduces water flow and leaves you scrubbing fixtures far more often than you’d like.

What Is the Best Way to Protect My Fixtures from Hard Water?

Sure, you can scrub the faucet or soak a showerhead in vinegar when the white crust shows up — it’ll shine again for a while. The trouble is that the trick only addresses what you can see. Inside the plumbing, the same minerals are still piling up, narrowing the pipes little by little and making the system work harder than it should.

That’s why many Houston homeowners opt for something more permanent. A water softener or conditioner doesn’t just cover up the problem — it treats the water before it ever gets to your fixtures. When the minerals are dealt with upfront, they can’t stick around to clog showerheads or leave crusty rings on faucets.

So yes, a scrub is fine for a quick win, but if you’re tired of fighting the same battle over and over, the better move is stopping the buildup before it starts.

Benefits of Installing a Water Softener in Houston

Installing a water softener to combat hard water in Houston works by treating the water before it flows into your home, preventing limescale from causing problems.

Homeowners notice the difference almost immediately:

• Fixtures stay cleaner longer without white crusts.
• Water heaters run more efficiently and last longer because heating elements don’t get coated in scale.
• Washing machines and dishwashers avoid the constant mineral buildup that wears out pumps and heating elements.
• Even your skin and hair feel better with softened water, since soap rinses away more easily.

Over the long run, softening your water extends the lifespan of your plumbing system and appliances, saving money on both repairs and replacements.

Stop Replacing Fixtures—Fix the Hard Water Problem

Replacing faucets, showerheads, or even water heaters every few years isn’t normal — it’s a symptom of hard water in Houston. While cleaning and regular maintenance can help, the only real way to protect your plumbing long-term is to treat the water at the source. A water softener or conditioner may be an investment upfront, but it pays off by reducing breakdowns, keeping your fixtures looking new, and helping your appliances run efficiently.

FAQ – Hard Water in Houston

Is hard water safe to drink in Houston?

Yes. Hard water is considered safe for drinking and cooking, though the minerals that make it “hard” are precisely what cause plumbing problems.

How can I tell if my home has hard water?

Look for signs of hard water in plumbing, such as white spots on dishes, clogged showerheads, soap scum that won’t rinse away, or skin that feels dry after showers.

Do I need a water softener or a filtration system?

It depends on what you’re trying to solve. If the big headache is scale — that white, crusty buildup that clogs fixtures and shortens the life of appliances — a softener is the tool for the job because it removes the calcium and magnesium causing the trouble. A filtration system has its benefits, but it won’t prevent limescale from forming on its own. In some Houston homes, the best setup is a combination of both: the softener tackles the minerals, and the filter handles taste, odor, or other water quality issues.

Why Choose Nick’s for Your Hard Water Issues? 

Hard water is a fact of life here, but you don’t have to keep dealing with the fallout alone. Nick’s Plumbing has been helping homeowners tackle hard water damage plumbing problems in Houston for decades.

What Is a Slab Leak and Why Is It So Dangerous?

In simple terms, it’s when a water or sewer pipe that runs beneath your home’s concrete foundation starts to leak. Since these pipes are buried under several inches of concrete and soil, the problem isn’t likely to be visible right away.

The danger comes from time. Water leaking beneath a slab has nowhere to go but into the soil supporting your home. Over weeks or months, it can weaken the ground under your foundation, leading to cracks, sinking, or uneven floors. And because many of Houston’s homes, primarily inside of or close to the 610 Loop, often sit on clay-heavy soil that already shifts continuously between wet and dry weather spells, slab leaks are more likely to occur and create instability for your home.

Key takeaways:

• Hidden location: Slab leaks happen under your home’s concrete foundation, making them hard to detect.
• Structural risk: Leaking water erodes soil and can undermine the stability of your foundation.
• Long-term damage: The longer it goes unnoticed, the worse—and more expensive—the repairs become.

How to Tell If You Have a Slab Leak

Since you can’t see under your foundation, you have to rely on indirect signs. Homeowners often discover a slab leak only after noticing something unusual with their floors, bills, or water pressure.

Common Signs of a Slab Leak:

High Water Bills: If your usage hasn’t changed but your bill suddenly jumps, that’s usually water leaking somewhere you can’t see.

Wet or Warm Spots: You might feel a warm patch on tile or notice carpet that never seems to dry — both are red flags for a hidden leak.

Musty Odors or Mold: That damp, earthy smell on the ground floor is often the first clue that moisture is trapped under the slab.

Cracks in the Foundation: Small cracks are common in any home, but if you notice new ones after the slab has settled, it could indicate that the soil underneath is shifting due to a leak.

Running Water Sound: You may hear the sound of running water when no fixtures are in use. 

Cracked Tiles: Water pressure can cause tiles and grout to crack or loosen. 

Early vs. Advanced Signs

At first, the only clue may be a higher water bill or a faint sound of water. As the leak progresses, the signs become harder to miss: cracks in walls or flooring, uneven doors and windows, or visible water pooling indoors. By the time you see structural issues, the slab leak has likely been there for months.

What Causes Slab Leaks in Houston Homes?

Houston homes are especially vulnerable to slab leaks thanks to our soil and climate conditions.

• Expansive clay soil: Houston’s soil swells dramatically when wet and shrinks during dry spells, putting constant stress on both foundations and pipes.
• Corroding pipes: Older copper or cast-iron pipes can deteriorate from hard water minerals or chlorine in the city supply.
• Abrasion and vibration: As water flows, pipes can rub against rocks, rebar, or the slab itself, wearing them down.
• High water pressure: Excess pressure accelerates wear and increases the risk of sudden leaks.
• Poor installation: Pipes damaged or improperly placed during construction are more likely to fail over time.

How Plumbers Detect a Slab Leak Without Tearing Up Your Slab

Say “slab leak” and most folks picture the worst — a plumber standing in your living room, jackhammer in hand, about to make a mess. The good news is that modern leak detection doesn’t usually look like that. These days, plumbers in Houston have a whole toolbox of gadgets that can sniff out a hidden leak without tearing the place apart.

Licensed slab leak plumbers in Houston rely on specialized gear to track down leaks that can’t be seen. Sometimes it’s as simple as using sensitive microphones that pick up the faint hiss of water escaping underground. Other times, thermal cameras spot warm patches from hot-water lines, or moisture meters confirm that hidden dampness is creeping up through flooring or walls.

The big advantage? With this kind of technology, plumbers can zero in on the exact trouble spot. That means less guessing, less demolition, and a repair that targets the leak instead of tearing up half the house.

Can Slab Leaks Be Repaired Without Breaking the Slab?

Yes, in many cases. While sometimes the only option is breaking through the foundation directly above the leak, other repair methods can spare your floors.

• Tunneling: Plumbers dig a tunnel under the home from outside to reach the damaged pipe. This avoids disrupting the flooring inside.
• Pipe rerouting: Instead of fixing the damaged pipe, plumbers bypass it by running a new line through the walls or the attic.
• Epoxy pipe lining: A trenchless option where an epoxy coating is applied inside the existing pipe to seal leaks.

Which option works best depends on the pipe’s location, the home’s age, and the overall condition of the existing plumbing.

How Much Does It Cost to Repair a Slab Leak in Texas?

The cost can vary widely. A simple spot repair through the slab may be less expensive upfront, but it is much more disruptive. Tunneling or rerouting will probably cost more in labor, but it may protect your interior finishes, like floors and walls. On average, Houston homeowners can expect slab leak repair to range anywhere from a few thousand dollars for minor work to significantly more if extensive tunneling or repiping is required.

Does My Homeowners Insurance Cover a Slab Leak Repair?

Insurance coverage can be tricky. Most policies will cover the damage caused by a slab leak, such as ruined flooring or foundation cracks, if the event is considered “sudden and accidental.” But the actual repair of the pipe itself is often not included.

That means your policy might pay for fixing the damage to your home, but you’ll still need to cover the cost of the plumbing repair yourself. Because every policy is different, it’s smart to call both a plumber and your insurance company right away should you suspect a slab leak.

Can a Slab Leak Cause Foundation Problems?

Absolutely. A continuous leak undermines the soil that supports your home. Over time, this can cause the foundation to settle unevenly, leading to cracks, warped floors, or even doors and windows that won’t close properly. In Houston, where clay soil already makes foundations vulnerable, a slab leak accelerates the damage dramatically.

Can Slab Leaks Be Prevented?

Sadly, there is no magic fix in our toolkit that can guarantee you’ll never have to worry about a water leak beneath your foundation, but there are a couple of things you can do to perhaps swing the odds in your favor. 

One of the most effective protective measure is to keep your water pressure in check. A pressure regulator installed at the meter will help to take the stress off your pipes, which translates to fewer chances for a line to burst.

Getting a plumbing inspection once a year is one of those simple habits that pays off. A licensed plumber can spot the little things — a bit of corrosion here, a pipe that’s shifting there — long before they turn into the kind of repair that wrecks your weekend and your budget.

Just as important is keeping your eyes and ears open around the house. If your water bill suddenly increases for no reason, you catch a persistent musty odor, or you hear a faint hiss even when everything’s turned off, don’t dismiss these signs. Those slight hints are often your first warning, and catching them early is always cheaper than waiting until they blow up into something bigger.

Why You Shouldn’t Wait to Fix a Slab Leak

Slab leaks aren’t the kind of problem that fixes itself if you give it time. Even a small leak can slowly wash away the soil under your foundation or keep enough moisture trapped to feed mold. The longer you let it go, the worse it gets — and the higher the bill climbs when you finally deal with it.

Catching it early usually means a straightforward repair. Waiting turns it into foundation cracks, warped floors, and the kind of damage that can snowball into a full-blown crisis. When it comes to slab leaks, “later” almost always equals “more expensive.”

FAQ – Slab Leaks in Texas Homes

Can a slab leak cause my water bill to go up suddenly?
Yes. Unexplained spikes in usage are often the first sign of a hidden leak.

Can a slab leak cause mold or mildew problems in my home?
Definitely, moisture trapped under flooring creates the perfect environment for mold, which can spread indoors.

Protect Your Houston Home’s Plumbing with an Expansion Tank

You rely on your water heater for warm showers, clean laundry, and day-to-day tasks, so when something goes wrong, it can throw your whole routine into chaos. Installing an expansion tank helps protect your system from pressure-related damage, extending its lifespan and reducing the risk of costly and inconvenient repairs.

In this guide, we’ll walk you through everything you need to know about water heater expansion tanks, from how they work to the benefits of installing one in your Houston home.

What Is a Water Heater Expansion Tank?

A water heater expansion tank is a small tank installed on the cold water supply line that helps protect the water heating system and plumbing from damage caused by thermal expansion.

How it works

When water is heated, it expands, and its volume increases. In a traditional closed system, the expanding water has nowhere to go and can cause pressure to build, leading to leaks or damage to your plumbing. An expansion tank provides a space for this extra water to go, relieving pressure and protecting the system.

The tank is typically made of steel or other materials designed to withstand high pressure, with a rubber diaphragm or bladder inside that separates air from the water. As the water expands, it enters the expansion tank and compresses the air or bladder inside. When you use hot water, the temperature drops, and the water inside the expansion tank flows back into the main water supply line.

Do Houston Homes Require Expansion Tanks?

Whether or not your water heater requires an expansion tank depends on the type of water heating system you have, the size of the system, and your local regulations.

In many areas of Houston, homes with closed-loop water heating systems require an expansion tank to prevent plumbing damage. These systems include those with a backflow prevention device, pressure-reducing valve, or check valve, as these devices trap water and lead to thermal expansion.

When you might not need one

A thermal expansion tank may not be necessary if your water heating system has an open plumbing system, such as an open-loop solar heating system or a gravity-fed system. If you’re unsure, consult a licensed plumber to determine whether your specific system requires an expansion tank.

Benefits of Installing an Expansion Tank

Installing an expansion tank on your water heater helps protect your home and plumbing from costly damage and repairs. Some of the top benefits you’ll see include:

• An extended water heater lifespan
• Reduced risk of costly issues like leaks, bursts, and early breakdown
• Improved system efficiency and lower utility bills
• Quieter water heater operation

Can I Install a Water Heater Expansion Tank Myself?

While it’s possible to install an expansion tank on your own, it’s best to leave it to the experts at Nick’s. Installation involves turning off the water supply, draining the water heater, and installing the expansion tank on the cold water supply line, which requires advanced plumbing knowledge and specialized tools. Improper installation can lead to leaks, water damage, and reduced heater efficiency, leaving you with costly repairs and more headaches down the line.

Common Causes of Expansion Tank Failure

Most water heater expansion tanks last between five and 10 years before requiring replacement. While age is the top cause of failure, there are a few other factors that can cause your tank to break down.

Corrosion

Over time, the interior of the tank may corrode due to the chemical reactions that occur with the water inside. Corrosion on the tank can weaken the walls, leading to cracks, leaks, and eventually failure.

Waterlogging

If the air bladder inside the expansion tank loses pressure or bursts, the tank can fill with water, without enough room to allow for thermal expansion in the water heater. If the tank becomes waterlogged, pressure will continue to increase and eventually cause the tank to fail. 

High pressure

High water pressure in your plumbing system puts excess strain on the tank and bladder, increasing the risk of wear, leaks, and bursts. If the pressure gets too high, it can cause the expansion tank to fail or rupture completely.

Poor installation

Incorrect installation of the expansion tank, such as improper orientation or connection to the system, can lead to failure. Without proper setup, the tank will struggle to function, leading to pressure issues, leaks, and early breakdown. 

Age & Wear

Like all mechanical components, expansion tanks have a limited lifespan and will eventually wear out and need replacement. Tanks nearing the end of their 10-year lifespan often lose efficiency and show signs of needing replacement.

Signs Your Expansion Tank May Be Failing

When your water heater’s expansion tank is nearing breakdown, you’ll often notice warning signs that it’s no longer working at its best, including:

• Leaks: Water leaking from the tank is often a sign that it may be failing.
• Reduced water pressure: If the water pressure in your home has dropped or the water flow from the hot water faucet is weak, it may be due to a failing expansion tank.
• Noisy pipes: If you hear banging or knocking sounds from your pipes when you turn on the hot water, your expansion tank may no longer be absorbing pressure.
• Rust or corrosion: Visible rust or corrosion on the outside of the expansion tank is a clear sign that the tank is deteriorating and needs replacement.
• Increased energy bills: A defective expansion tank can cause your water heater to work harder than necessary, leading to higher energy usage and rising utility bills.

How Long Does a Water Heater Expansion Tank Last?

The lifespan of a water heater expansion tank varies depending on factors like usage, water pressure, and the quality of the tank itself. On average, an expansion tank can last 5 to 10 years with regular professional maintenance. 

To prevent unexpected failure of your tank, routinely check for signs of damage or wear, such as leaks or rust, at least once a year. If you notice any problems, contact a licensed plumber to inspect and replace the expansion tank if necessary.

What’s the Cost to Install or Replace an Expansion Tank in Houston?

The cost to install or replace a water expansion tank varies depending on the type and size of the tank, its location, and the cost of labor in your area. Prices can range from $150 to $500 for a standard installation. The cost can increase if additional plumbing work is needed or the installation is more complex.

Manufacturers often provide tank warranties that can help offset the replacement cost if the tank fails within a certain period. Many plumbing companies, like Nick’s, also offer financing options that allow you to spread the cost of a new tank into easy monthly payments tailored to your budget.

Frequently Asked Questions

Do I need an expansion tank on a tankless water heater?

Tankless water heaters operate on an open system, providing water on demand rather than storing it. Because there’s no storage tank, you don’t have to worry about building pressure, and you won’t require an expansion tank. 

Do expansion tanks require maintenance?

Expansion tanks require annual maintenance to check for proper function, inspect for leaks, and perform pressure tests. When you schedule water heater maintenance with our experts, we’ll include a comprehensive inspection of your tank.

How do I know if my expansion tank is waterlogged?

The top signs your expansion tank is waterlogged include visible leaks, noisy pipes, and reduced water pressure. If you notice any of these warning signs, contact our team for repair.

While your disposal is built to handle everyday scraps, summer food waste presents a more formidable challenge. Watermelon rinds, corn husks, greasy grill pans, and rib bones aren’t exactly “light duty” for your disposal. Add in the temptation to rinse everything down the drain after a big party, and you’ve got a perfect storm for clogs, jams, and even complete breakdowns.

What Poor Garbage Disposal Summer Habits Can Cause Breakdowns?

Overloading After BBQs or Parties

Summertime get-togethers lead to heavier kitchen use—and even a heavier load of food waste. It’s common to toss significant amounts of scraps down the drain in a hurry, especially when cleaning up after a crowd. That said, overloading your garbage disposal can dull the blades, overheat the motor, or cause it to lock up entirely. Bones and dense food items can crack or jam internal components, forcing the motor to work harder or to give up altogether.

Grease and Oil Buildup

Pouring hot cooking grease down the drain might seem harmless in the moment, but as it cools, it hardens into this thick, gummy sludge that clings to the inside of your pipes and disposal walls. Over time, this sticky buildup will trap other food particles and other debris, eventually forming a clog that backs up waste into your sink. 

Tough and Fibrous Summer Produce

Summer produce like corn, melons, and leafy greens often come with hard rinds or stringy fibers. Corn husks and celery strings can tangle in the impellers, while watermelon rinds or fruit pits can stop the blades completely. This isn’t a level of trash that is simply a little more challenging to grind—it’s a situation that can be risky to your disposal’s lifespan.

Neglected Cleaning and Maintenance

Disposals that see more use in the summer are also going to require more of your attention, which means practicing a little DIY drain maintenance. When food particles and other debris get stuck in the grinding chamber, they can cause unpleasant odors. Over time, neglected debris can harden or start to grow mold, affecting performance. If your disposal hums but doesn’t grind when turned on, it might be dealing with an internal buildup issue instead of a mechanical fault.

How Can I Tell If My Garbage Disposal Is Failing?

If your garbage disposal starts acting up more often during the summer, it’s probably not a coincidence, as increased usage tends to amplify minor problems.

• Humming But Not Grinding: This typically means something is stuck in the impeller or the motor is straining as a result of a blockage.
• Frequent Jams or Slow Draining: A sign that food waste or grease buildup is slowing down the system.
• Persistent Bad Smells: Trapped debris and bacterial growth can cause foul odors that linger even after rinsing.
• Leaking from the Base or Sides: Indicates that internal seals or gaskets have worn out, possibly from overuse. 

These are all symptoms that your disposal is overworked—and lax summer plumbing habits are probably to blame.

How to Prevent Summer Garbage Disposal Damage

Most disposal problems can be avoided with a few simple changes to how you use the appliance:

• Break Up Food Waste: Feed small portions into the disposal slowly rather than dumping a whole plate of scraps in at once.
• Run Hot Water: Always let the hot water run for several seconds before, during, and after using the disposal. It helps move debris through the pipes and flushes away as much waste as possible.
• Keep Starchy and Fibrous Foods Out of the Disposal: Kitchen waste like potato peels, pasta, corn husks, and banana peels should be thrown into the trash instead. These foods can swell, end up wrapped around the impeller, or get trapped somewhere inside the disposal mechanism.
• Try Some DIY Tricks to Help Your Disposal: Throw a handful of ice cubes down the drain and run the disposal to knock loose some of the debris. Follow that up with a baking soda and vinegar flush – use one cup of each, pouring the baking soda first, followed by the vinegar. Failure to follow the steps in this order will leave you with a dry lump of baking soda in your sink and a puzzled look on your face. If you do it right, it’ll take you right back to that volcano you made in 5th-grade science class. Now, throw some citrus peels or small lemon wedges into the disposal and run it -along with some hot water-to clear out any remaining odors.
• Don’t Ever Pour Grease Down the Drain: Allow it to cool and solidify, and dispose of it in the trash to prevent pipe-clogging buildup. As you’re moving it to the garbage can, ask yourself if you want that oily clump hanging out in your drain or sewer lines.

With just a little extra care, it’s easy to keep your disposal running smoothly—even during the busiest kitchen season of the year.

When Should I Call for Garbage Disposal Repair in Houston?

If your disposal stops working entirely, there are a couple of DIY tricks that may get it back up and running. You may be able to fix it by pressing the reset button—usually located on the bottom of the unit. But when that doesn’t work, or the same issue continues to occur, it’s time to get professional disposal repair help.

• The Reset Button Doesn’t Work: This indicates a more serious internal issue than a simple motor overload.
• The Disposal Hums But Won’t Spin: Likely caused by jammed blades or a seized motor.
• Sink Water Backs Up: Usually, the sign of a clog in the drain line or perhaps a failure in the grinding mechanism.
• Visible Leaks or Strange Noises: These are signs of worn-out seals, loose components, or a motor on its last legs.

At Nick’s Plumbing, we’ve handled just about every possible garbage disposal failure you can imagine, and they always seem to spike during Houston summers. Whether your blades are jammed or the motor’s gone radio silent, we’ll quickly diagnose and repair the issue, or install a new unit if necessary.

“Summer plumbin’, my pipe had a crack,

  Summer floodin’, it happened so fast!”

Most homeowners tend to only associate catastrophic plumbing pipe damage with freezing winter temperatures. Here in Houston, the summers can be just as, if not even more brutal for your plumbing, as intense heat, high humidity, and surging water use all contribute to a perfect storm that puts your pipes under tremendous pressure. 

Pipe cracks, leaking hose bibs, and even burst water supply pipes aren’t just cold-weather problems.

Houston’s relentless summer temperatures don’t just affect your comfort level; they make your pipes uncomfortable as well. Heat can significantly impact the materials that comprise your plumbing system. 

If you have noticed a drop in water pressure, strange puddles around the property, incredibly lush, green grass in just one area of the yard, or a spike in your water bill during the summer months, your pipes could be trying to tell you something.

How Heat Affects Pipes: Expansion, Pressure, and Stress.

When it gets hot, materials expand. Pipes made from metal, either copper or galvanized steel, are prone to heat-related expansion, but will usually contract once the temperature goes back down. These constant expansion-and-contraction cycles put excessive strain on pipe joints, seals, and fittings, which will eventually lead to leaks or cracks. PEX and other pipes made of flexible plastics can become too soft under extreme heat and struggle to maintain pressure.

So while your plumbing system is enduring this torture, add to the equation the fact that Houston summers bring water use way up. Sprinklers, swimming pools, pressure washing, and (hopefully) more showers will mean higher water pressure throughout the system. That added pressure can exacerbate minor weaknesses in your pipes, sometimes transforming a hairline crack into a full-blown rupture.

Tree Roots: The Hidden Threat to Underground Pipes

Trees and plants love summer. Unfortunately, so do their roots. As the soil heats up and dries out, tree roots stretch farther in search of moisture—and underground plumbing lines make a tempting target. Once roots find a crack or loose joint in your pipes, they begin to creep in, widening gaps, and creating a blockage to the wastewater flow.

You won’t be able to see this happening, as roots infiltrate your sewer line, but you might be lucky enough to observe early symptoms, such as slow drains, odd gurgling noises, or standing water in your yard. 

If left unaddressed, root intrusion will cause significant damage to your sewer line that will necessitate either sewer pipe re-lining or a complete replacement. Now, even though both methods involve some excavation of your yard, a sewer pipe relining doesn’t require us to perform the “open yard surgery” that a complete sewer line replacement would require. 

UV Radiation and Outdoor Plumbing Exposure.

If you have exposed pipes outside—perhaps under a deck, along an exterior wall, or in an uninsulated attic—they are especially vulnerable during Houston’s peak summer months.

Have you ever tried to get cold water out of your kitchen tap in July or August, only to have “slightly less than hot” water flow out, regardless of how long you let it run? That’s a sign that your pipes (and probably the city or municipality’s pipes as well) are overheated. Direct sunlight will quickly warm those pipes up. Over time, direct UV exposure will break down certain plastics, like PVC, making them brittle and prone to cracking.

Even if a pipe doesn’t split outright, heat-stressed fittings and connections will eventually start to leak. Unfortunately, these minor leaks often go unnoticed until they’ve already had a head start at causing extensive water damage or mold issues.

Shifting Soil: A Problem for Foundations, and a Problem for Pipes.

Houston has to deal with two extremes during the summer months. The first being our extreme summer heat that causes the soil to dry out, shrink, and shift—especially in areas with clay-heavy soil, which is most of the Houston area. 

Now, of course, what summer in Houston would be complete without the daily, torrential downpours that we get for weeks at a time? Once all of that excess rainwater seeps into the dry, shriveled soil, it starts to expand. When that happens beneath your home, it isn’t just going to shift your foundation around; it will also knock underground pipes out of alignment or cause them to crack from increased pressure.

This is particularly concerning for many older homes in our historic districts that still have their original 1930s – 1960s plumbing, as the pipes laid decades ago weren’t designed to withstand the soil movement caused by today’s hotter, drier summers. Plus, when you factor in just how much the population has grown in and around Houston, you start to understand the degree of stress our plumbing is under. 

Warning Signs That Heat Has Damaged Your Pipes:

• Sudden drop in water pressure.
• Discolored water from taps.
• Unexplained wet spots in your yard or around your slab.
• Water meter spinning even when all fixtures are turned off.
• Recurring drain backups or slow sinks.

If your plumbing system is showing any of these symptoms during the summer months, don’t ignore them; call Nick’s Plumbing to evaluate the damage and recommend the appropriate solution. What seems like a minor issue today could become a serious plumbing repair nightmare if it’s left alone to fester for too long.

Simple Ways to Prevent Summer Pipe Damage.

Houston’s summer heat isn’t just hard on you—it can wear down your plumbing, too. But with a few proactive habits, you can keep your pipes in better shape and lessen the chance of unpleasant surprises.

• Insulate Exposed Pipes: While it’s intuitive to think the opposite, the same foam insulation wraps you use to keep your pipes from freezing in the winter will also help regulate pipe temperature and reduce the risk of expansion-related cracks or bursts throughout the summer months. Foam pipe wraps are also able to protect outdoor piping from UV damage.
• Be Smart About Water Use: Try to limit heavy water usage to the hours of non-peak use, as opposed to in the early morning or late afternoon. By spreading out your irrigation and laundry loads, you can help reduce strain on both your home’s plumbing and the city’s water supply.
• Schedule a Mid-Summer Plumbing Check-Up: A complete plumbing inspection and maintenance service call allows us to catch early signs of any underground damage like pipe shifting, corrosion, or hidden leaks before they escalate into full-on emergencies.
• Inspect All Outdoor Fixtures: Anything that is capable of delivering water to the property outside your home, including hose bibs, sprinkler heads, and pressurized irrigation lines, will take a beating in the extreme heat and direct sun. 
• Keep an Eye on the Trees: If you’ve got large trees near your main sewer line, a camera inspection can confirm whether your tree’s roots are minding their own business—or trying to get a little overly friendly with your sewer line.

When to Call for Professional Plumbing Help.

If you’re noticing frequent leaks, pressure issues, or you’ve had pipe repairs in the past, it’s worth having a licensed plumber evaluate your system. A professional can spot warning signs you might miss and recommend solutions tailored to Houston’s unique climate.

Basic regular maintenance and repairs of minor issues should be done now to prevent larger problems, such as rerouting a vulnerable section of pipe or installing a pressure regulator on your water meter. Don’t wait until a pipe bursts in the middle of a summer heatwave.
