Water Heater Repair in Annandale, VA
67% of households in Annandale heat with gas. That is the strongest free clue to what kind of water heater is in your basement, and it decides which faults are even possible.
Answer first
67% of Annandale households burn gas for heat, and a water heater almost always sits on whatever line the furnace already uses. That is house heating fuel, so read it as a strong hint rather than as a reading of your own tank. On a gas heater the suspects are the pilot, the thermocouple and the gas control valve, in that order.

What Annandale runs on
With gas clearly in front, most tanks here burn it. That puts the usual faults on the burner side — pilot, thermocouple, gas valve — rather than on elements and thermostats.
| Fuel | Share of households |
|---|---|
| Gas — mains and bottled | 67% |
| Electricity | 30% |
| Fuel oil and kerosene | 2% |
| Everything else | 1% |
US Census Bureau, American Community Survey, table B25040, 2023 5-year release. The universe is 18,917 occupied housing units in and around Annandale.
That sits 20 points higher than the Virginia average, which is why we publish the town figure rather than the state one.
That figure is house heating fuel, not water heater fuel. They correlate strongly, because the same gas line generally serves both, but the Census does not publish the second one and we are not going to pretend it does.
Which one do you have
If you are not sure, look at the top of the tank: a flue pipe going up into the ceiling means gas, and no flue at all means electric. The fuel decides the fault list, so start there rather than with the symptom.
With the fuel settled, read across to the symptom: none, not enough, noise, or water where it should not be.
