Water heater repair (thermocouple, gas valve, element, thermostat, burner)

Where the repair lands depends on the part: a thermocouple or an element is a short job, a gas control valve takes longer and costs more, and either way you see the number before we start.
Water coming out of the tank body itself can’t be repaired. That’s a replacement, and the installed prices for one are on our water heaters page.
What’s different in Catharpin
Almost no Catharpin house is on natural gas. The Census puts about half of owners on electric heat and about a third on propane, and the water heater usually follows the furnace. That sorts the repair into two piles. A propane tank behaves like a gas one, so the usual suspects are the pilot, the thermocouple and the gas control. An electric tank fails at the element, the thermostat or a tripped high-limit reset.
The odd one in this town is the propane house where the water heater simply went cold overnight. Before anyone touches the tank, look at the gauge on the yard tank. When the supply runs low, or the regulator by the house ices up or fails, the pilot goes out and every gas appliance goes with it. A refill and a relight cost nothing to try. If the gauge reads fine, then it is the tank.
Every house in this ZIP is detached, and the median home dates to 1986, so the tanks sit in basements, crawlspaces and garages on lots with room to spare. That helps a repair, since there is space to work. It hurts when a slow leak goes unseen, because nobody walks past a crawlspace tank every day. If you haven’t looked at yours since you moved in, look this week.
Out here the water may come from a private well, and well water that carries iron or grit shortens the life of a lower element and clogs the drain valve. When we test an element and find it burnt out at the bottom, we’ll ask about your water, and say so if a flush belongs with the repair.
The signs
Country power lines drop out in storms. After an outage, press the red reset button on the electric tank’s thermostat cover (breaker off first). If it keeps tripping, the element has failed.
On a gas tank that’s usually the pilot, the thermocouple that keeps it lit, or the gas valve. On an electric tank, it’s usually an element or the reset that tripped.
A shower that goes cold in five minutes often means a failed lower element on an electric tank, or a tank so full of sediment that it heats far less water.

Choosing who does it
Questions to ask anybody who looks at your tank, us included.
Propane, electric and gas tanks fail in different places. A tech who knows which one you have, and checks the fuel supply first, saves you a trip charge for nothing.
A plumber who goes straight to replacement without testing the thermocouple, the valve or the elements may be selling you a tank you don’t need.
A repair that leaves a stuck relief valve or a bad vent connection behind isn’t finished. Ask what else they looked at while the cover was off.

SwiftPro delivered and installed a 75 gallon AO Smith water heater. Zabi was very professional in his communication, plumbing, testing, and cleanup. Good crew to move new heater to basement utility room and take out the old heater.

Questions
On propane, a weak pilot flame, a bad thermocouple or a regulator problem at the yard tank are the usual causes. On electric, it is a failing thermostat or element. We test each before replacing anything.
The visit to find what’s wrong is $49, $250 after hours. The repair is priced in writing at the tank, before we start, because a thermocouple and a gas valve are very different jobs.
Repair it when the tank is sound and a part failed. When the tank itself leaks, it’s a replacement, and we’ll show you where the water is coming from before you decide.
