Why is my gas water heater leaking?

Gas water heaters leak due to corrosion inside the tank, worn valves, or too much pressure buildup. If water is pooling under the unit, the tank may be cracked and needs replacement.

Can I still use my gas water heater if it’s leaking?

No, using a leaking water heater can cause serious damage or even a flood. Turn off the gas and cold water supply and call a licensed plumber immediately for inspection.

How do I shut off my leaking gas water heater?

Turn off the gas supply at the shut-off valve near the base of the unit. Then, shut off the cold water valve going into the tank. This prevents further damage until help arrives.

Can a leaking gas heater be repaired?

It depends. If the leak is coming from a valve or connection, a repair might work. But if the tank itself is leaking, it’s not repairable and should be replaced.

Yes, I provide full gas water heater replacement services in Churchville. I’ll inspect the issue, explain your options, and install a high-efficiency unit that fits your home and budget.

How do I know if my water heater tank is about to fail?

How long do gas water heaters typically last in Churchville, NY?

Most gas water heaters last 8 to 12 years, depending on the water quality and maintenance. If yours is older, it may be more cost-effective to replace it now before it leaks.

Gas Water Heater Leaking in Churchville? Here’s What to Do Before It Fails

Gas Water Heater Leaking in Churchville? Don’t Wait for a Flood

Hi, I’m Nate, owner of NDL Plumbing & Electrical. If you’re in Churchville and notice your gas water heater leaking, don’t ignore it.

Even a small drip can quickly escalate into a significant problem.

A leak doesn’t just waste water. It’s a warning sign. And if you act quickly, you might avoid a complete failure (and a flooded basement).

Let’s break down what it means, what causes it, and what to do next.

First: Is It Really Leaking?

Sometimes, what appears to be a leak isn’t coming from the tank itself. Here’s where to check:

Cold and hot water connections at the top of the tank
Temperature and pressure relief (T&P) valve on the side
Drain valve near the bottom
Condensation on the tank in humid months

If the water is coming from underneath or pooling near the base, though, that usually means the tank itself is cracked.

At that point, it’s not repairable.

Why Gas Heaters Leak in Churville Homes

Over time, even the best water heaters wear out.

Churchville has a lot of homes with older units, and I see the same issues over and over:

Internal corrosion from minerals in the water
High pressure from a faulty thermostat or expansion tank
Old age—most gas heaters last 8 to 12 years

Once rust starts eating away at the inside, it’s only a matter of time before it leaks or bursts.

What You Should Do Right Now

If you see active leaking:

Turn off the gas supply to the water heater (usually a valve near the bottom)
Shut off the cold water valve going into the tank
Call me right away—I can inspect it and give you an honest answer fast

The sooner you act, the better your chances of avoiding significant damage.

Don’t Wait for a Flood

I’ve been in homes where people waited just a little too long, only to come home to a soaked basement and thousands of dollars in damage.

A leaking gas water heater is a slow, progressive failure.

I’ll help you determine whether a repair is possible or if it’s time for a new, energy-efficient model that’ll keep your water hot—and your utility bills low.
