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 Catlett
Catlett’s water pressure comes from a tank on a tower, and it explains a few water heater problems.
The village water system is run by the Fauquier County Water and Sanitation Authority. Its own report describes two drilled wells, 264 and 270 feet deep, that pump up to an elevated storage tank, and the height of that tank is what gives Catlett its pressure. Pressure from a tower is steady and fairly gentle, which is easy on a water heater. It also means a tank here usually fails from age or a bad part, not from pounding.
About half of Catlett owners heat with electricity and nearly three in ten with propane. So the common repairs are elements and thermostats on one side, and a pilot, thermocouple or gas control on the other. Nearly all homes are detached and the median was built in 1990, so most tanks sit in a basement or crawlspace, where a drip can run for weeks before anyone sees it.
One check that is worth doing in any house with steady pressure: the relief valve on the side of the tank. If it drips, the cause may be pressure creeping up when the tank heats, or a valve that is worn out. Some Catlett houses have a closed system, with a check valve at the meter, that has no place for that expansion to go. A small expansion tank is the fix. We will tell you if one is missing.
Houses outside the village service district are on their own wells, with a pressure tank in the basement. A pressure tank that has lost its air cushion causes pulsing at the taps, and people blame the water heater. We look at both before we say which one is the problem.
By the numbers
Catlett houses, by the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
Catlett
ZIP 20119 as a whole: every Catlett address, the village included. The Census place for the village alone has too few homes for steady figures.
- Median home built1990 Census
- Built before 1980about 4 in 10 Census
- Built since 2000about 2 in 10 Census
- Most homes aresingle-family houses, nearly all Census
- Heated withelectricity, about 5 in 10 Census
- Rentedabout 2 in 10 Census
- Many houses here heat with electricity, and an electric water heater fails differently: an element, a thermostat or a tripped reset.
- Most homes here are detached houses with the tank in a basement or garage, where there’s room to work and a floor drain nearby.
The signs
When a Catlett water heater needs a repair.
No hot water at all
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.
Hot water runs out fast
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
How to pick who repairs a water heater in Catlett.
Questions to ask anybody who looks at your tank, us included.
Did they check for an expansion tank?
A closed plumbing system needs one. Without it, the relief valve takes the abuse, and a tank can age faster.
Did they name the part before quoting a new tank?
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.
Did they check the relief valve and the venting?
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
Water heater repair questions from Catlett.
Is Catlett’s water hard on a water heater?
The Authority’s report doesn’t print a hardness number for Catlett, so we won’t guess. A sink test kit tells you in a minute, and a look inside the tank tells us more.
How much is water heater repair in Catlett?
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.
Should I repair my water heater or replace it?
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.
