Water Heater Repair

Water on the floor at the base of the tank usually means the tank itself has gone, so shut off its water supply and kill the gas or the breaker before anything else.

When this becomes an emergency

What a pro does

The plumber's first split is leaking versus not heating, because one of those is a repair conversation and the other often isn't. A drip from a fitting, the valve on top, or the temperature and pressure relief line is a part. Water seeping out from under the jacket means the inner tank has rusted through, and no part fixes that. If it's a heat problem, he tests the elements and thermostats on an electric unit or works through the pilot, the thermocouple and the gas valve on a gas one. He'll drain some of the tank while he's there, and in this part of the state that's often informative on its own. Well water and hard municipal water both leave a mineral layer on the bottom that acts like insulation between the burner and the water. Sediment shows up in the recovery time long before it shows up as a failure. He also checks the relief valve and the expansion setup, since those are safety items people forget the heater even has.

Frequently asked questions

It varies with water quality more than anything. Sediment and dissolved iron shorten it, and a tank that's never been flushed works harder its whole life. Once the tank body itself is leaking, age stops mattering, because that's the one failure that can't be repaired.
That's likely the temperature and pressure relief line doing what it's designed to do, which means something is causing excess pressure or heat. It's a safety device, so it shouldn't be capped or ignored. It needs somebody to find out why it's discharging.
It generally helps, since the sediment load is higher. But on a tank that's gone many years without it, disturbing the layer at the bottom can uncover thin spots that were being held together by the crust. A plumber will look at the age before deciding how aggressive to be.
Often it can, and there are reasons to want to, mostly access and the fact that a leak under the house goes unnoticed. Relocating means new water lines, new venting or new electrical, and a proper drain pan location, so it's planned work rather than a swap in place.
