Relief valve leak?
We dry it out

Is a dripping relief valve dangerous?

The temperature and pressure (T&P) relief valve is a safety part. If it drips or releases water, it may be doing its job because pressure or temperature is too high, or it may be worn out. Do not cap or plug it. Shut off the cold water supply, and have a plumber check it. Meanwhile, the water it released may be soaking the floor or the wall it drains past. That is where our water heater leak cleanup comes in.

Leak by location

Where A.O. Smith heaters leak and what it means

Where A.O. Smith heaters leak and what it means
Where the water is	Likely cause	What happens next
From the relief valve or its discharge pipe	High pressure, thermal expansion, or a worn valve	A plumber checks pressure and the valve
Pooled under the tank	Inner tank rusted through, or the drain valve	Tank leaks mean replacement
Around the top fittings	Loose or corroded connections	Often repairable
Under a tankless unit	Fittings, relief valve or condensate line	Plumber service plus drying
Drips on a new, cold tank	Condensation	Usually stops as the tank heats

The expansion factor

Why thermal expansion makes relief valves leak

Water grows a little when it heats up. In many homes, that extra volume has nowhere to go, because a pressure reducing valve or backflow device stops it from pushing back into the city line.

What that does to your heater

Pressure climbs each time the heater runs. The relief valve opens to protect the tank and lets water out. Over time, the valve can start to weep or drip, and the tank and fittings wear faster.

The fix a plumber may suggest

A small thermal expansion tank on the cold line gives the extra water a place to go. Many plumbers include one with a new heater.

Where the water goes

If the discharge pipe does not run to a drain, the water lands on the floor, sometimes in a closet next to carpet or hardwood. We check those spots with moisture meters, then dry the structure.

Not sure where it is coming from?

Water running down the outside of the tank can look like a tank failure. Our leak detection tools help trace it.

Make sure the relief valve pipe runs to a drain or outside, not onto the floor.

FAQs

A.O. Smith water heater leak questions

Why is my A.O. Smith relief valve leaking?

Common reasons are high water pressure, thermal expansion with no expansion tank, very high water temperature, or a worn valve. A plumber should check it. Never plug or cap a relief valve.

Is A.O. Smith the same as State, American or Reliance?

A.O. Smith makes water heaters under several brand names, including State, American and Reliance. They tend to share similar designs and leak points.

Is my A.O. Smith tank leak covered by warranty?

The tank warranty usually covers the heater, not the water damage to your home. Homeowners insurance usually covers sudden water damage. Check both.

How do I shut off an A.O. Smith water heater?

Close the cold water valve above the tank. On gas models, turn the gas control knob to OFF or PILOT. On electric models, switch off the breaker if you can reach it safely.

Can water from the relief valve damage my floors?

Yes, if the discharge pipe ends near the floor instead of a drain. Repeated discharges can soak subfloor and baseboards over time.

Do you install expansion tanks or water heaters?

No. We clean up and repair water damage. A licensed plumber handles heater and expansion tank work.
