Water Heater Repair

Water pooling under the tank body, or a relief valve discharging on its own, means shutting off the supply and the gas or breaker and calling rather than watching it.

When this becomes an emergency

What a pro does

Age and water chemistry are the two facts a plumber wants early, because together they explain most of what goes wrong with a heater in this region. Groundwater across New Mexico carries a heavy mineral load, and every heating cycle drops some of it into the bottom of the tank. That bed reduces the volume of water the tank can actually hold and forces the burner to fire through an insulating layer, so recovery slows and the unit runs longer for less result. Draining and flushing removes what will move. Not all of it will after enough years. The anode rod gets pulled and inspected too, since it's the part designed to corrode instead of the tank, and a rod that's been eaten away means the steel shell is now on its own clock. On electric units the elements come out for a look, because scale forms directly on them here and a coated element runs hot and fails early. Whether the answer is a service or a replacement comes down to what the inspection turns up and how far along the tank already is.

Frequently asked questions

More often than the manual suggests for an average supply. Water this mineral heavy builds sediment faster, and a tank that goes several years without a flush can end up with a layer thick enough that draining won't shift it any more.
It corrodes on purpose. The rod is a sacrificial metal that gives the water something to attack besides the steel lining of the tank, and once it's consumed the tank itself starts taking that wear. Replacing a rod is far less work than replacing a heater.
It reduces the mineral load reaching the tank, which is the mechanism behind most of the scale trouble here. It isn't a cure for an already scaled unit and it brings its own maintenance, but on hard supply it changes what the heater has to deal with every cycle.
