Water Heater Repair

If water is coming from the tank itself rather than a connection, shut the cold inlet valve and kill the power or gas to it, since a corroded tank can open up without much warning.

When this becomes an emergency

What a pro does

A repair call starts with deciding whether the tank is worth repairing at all, and an honest plumber says so early. Leaks at the fittings, a failed thermostat, a burnt element or a bad gas control are all repairs. A tank weeping from the shell is not. From there the work depends on the water. In the sandhills and across rural stretches of North Carolina a great many homes run on private wells, and well water carries whatever the aquifer holds, which around here often means iron and a fair bit of dissolved mineral. That loads the bottom of the tank and it consumes the anode rod, the sacrificial magnesium or aluminum rod that corrodes so the steel does not. Checking that rod is the single most useful thing anyone does to a water heater, and on most tanks nobody ever has. The plumber drains and flushes the sediment out, pulls the rod to see what is left of it, checks the relief valve, and looks at whether the expansion tank on a closed system is still holding air. Small things, done in order, and they're what keeps a tank alive.

Frequently asked questions

It corrodes on purpose. The rod is a more reactive metal than the steel tank lining, so the water attacks it first and the tank keeps its integrity. When it is used up, the water starts on the tank itself, and that is the point where a heater begins its last few years.
It can, depending on what is in it. Iron and high mineral content leave more sediment in the bottom of a tank and can put a rotten egg smell in the hot water through a reaction with the anode. Knowing your water test results helps a plumber pick the right rod material and flushing interval.
Water trapped under a layer of sediment on the tank floor boils and forces its way up through it, and the sound is that steam escaping. It is telling you the burner or the lower element is heating a mineral bed rather than the water, which costs energy and shortens the life of the tank.
On a tank that has been flushed regularly, yes. On one that has gone fifteen years untouched, disturbing a heavy sediment bed sometimes reveals a weakness that was already there. A plumber will tell you which situation you are in before opening the drain, so the decision is yours.
