About Our Water Heater Leak Repair
We handle one problem: water heaters that are losing water. Water heater leak repair starts at the top of the tank, works down to the floor, and ends with the fix that matches the leak: a valve, a fitting, a gasket, or a new tank when the tank has failed.

A leak is a part, not a verdict.
Most leaking water heaters are a valve, a fitting or a connector. The tank only gets replaced when the tank is the thing that is leaking.
Why Homeowners Call Us for Water Heater Leak Repair
The leak gets a name
Leaks run down a tank and show up far from where they start. For water heater leak repair, the source is traced from the top fittings down before any part is replaced.
No automatic new tank
A dripping valve is a valve. You only hear the word replacement when the tank itself is what is leaking.
Pressure checked, not just parts
A relief valve that keeps opening is often reacting to pressure. That gets measured during water heater leak repair, so the new valve doesn't drip next month.
Tested before we leave
The heater is refilled, brought up to temperature and checked at every joint before the job is called done.
Water Heater Leak Repair Cost
Most homeowners pay an estimated $150 to $600 to fix a leaking valve or fitting, and an estimated $1,200 to $3,500 when the tank itself has to be replaced. For water heater leak repair, the written quote comes before any work.

Water Heater Leaks We Fix Every Week
Dripping relief valve
The valve opens at 150 psi or 210 °F. A steady drip means a worn valve or a pressure problem.
Weeping drain valve
Plastic drain valves wear out. A new brass valve usually ends it.
Water from the tank body
Rust and water at the seam or base mean the tank has corroded through. That one gets replaced.
Water in the pan
The pan is wet, but the cause may be condensation, an AC line or relief discharge.
Element or control valve seep
Gaskets behind an element panel, or the threads of a gas control valve, let water out.
Leak at the expansion tank
The small tank on the cold line, or its connection, starts to drip.
Rust-colored water
Rusty hot water or rust streaks on the tank can mean corrosion inside.
Popping and rumbling
Sediment on the bottom of the tank, which also wears it out faster.
Tank seam or bottom leaking
Water from the steel tank itself, the one leak that means replacement.

Call (555) 010-0100How much does water heater leak repair cost?
Most water heater leak repair jobs cost an estimated $150 to $600 when a valve, fitting or connector is leaking. A leaking tank is replaced, estimated at $1,200 to $3,500. You get a written quote before any work starts.
Can a water heater that's leaking be repaired?
Often, yes. Leaks at the relief valve, drain valve, connectors, nipples or gaskets are repaired. Water from the tank body or bottom seam is not repairable, and the heater is replaced.
What is the most common cause of a water heater leak?
The temperature and pressure relief valve and the drain valve, followed by the connections on top of the tank. On older heaters, corrosion inside the tank is the cause.
Should I turn off the hot water heater if it is leaking?
Yes. Set the gas control to OFF or switch off the breaker for an electric heater, then close the cold supply valve on top. If that valve won't turn, close the main.
Is a leaking water heater an emergency?
A steady flow or spray is: turn the heater off and close its cold supply now. A slow drip from a valve is urgent rather than dangerous, but book it within a day or two.
