Test the old valve before you need it
Turn the cold shutoff above your tank a quarter turn and back. If it’s stiff or leaks at the stem, tell us. You want to find that before the day the tank fails.

Water heater repair (thermocouple, gas valve, element, thermostat, burner)
Priced in writing at the tank, before we start
Prices checked .
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 Vienna
Vienna is a gas town, and a lot of the houses around Maple Avenue are old.
Eight in ten Vienna owners heat with gas, which is higher than almost anywhere else we work, so a gas water heater is the default here. The median owner home went up in 1972, and about one in five dates from before 1960. Those older streets, off Maple Avenue and Church Street, are where we find the most unusual setups.
An older Vienna basement can hold a tank that has been moved, resized and repiped over the decades, with a mix of copper, galvanized and newer fittings around it. The shutoff above the tank is often an old gate valve that won’t close all the way, or won’t reopen once closed. We test it before we touch anything, because a valve that sticks changes how we do the job.
The gas side is the usual list: pilot, thermocouple, gas control, burner. In houses that still vent through a masonry chimney, we also check the draft, since a furnace swap can leave an old tank venting badly. A sound tank with a bad part is worth fixing. A tank with a rusted base and a weep at the seam isn’t, and we’ll show you.
Vienna has a lot of remodeled houses too, with a finished basement built around the old water heater. Tell us where the tank is, and whether there’s a floor drain. If it’s behind a door in a finished room, we’ll bring floor protection. The repair is priced in writing at the tank, and our plumbing page lists what else we handle.
Neighborhood by neighborhood
What fails on water heaters across Vienna.
Census figures for the owner-occupied homes in each place, and what usually fails on the water heaters in houses like them.
By the numbers
Vienna houses, by the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
The Town of Vienna
Nearly the whole town sits in 22180, which it shares with county streets toward Dunn Loring and Merrifield.
- Median home built1972 Census
- Built before 1980about 7 in 10 Census
- Built since 2000about 3 in 10 Census
- Most homes aresingle-family houses, about 8 in 10 Census
- Heated withgas, about 8 in 10 Census
- Rentedabout 2 in 10 Census
- Most houses here heat with gas, and most of those have a gas water heater too, where no hot water usually comes down to the pilot, the thermocouple or the gas valve.
- Older houses often have the tank in a basement corner with an old shutoff valve above it that won’t fully close, so we check the valve before we drain anything.
The county side, around Wolf Trap
Vienna mail outside the town line: Wolf Trap and the Tysons edge in 22182, the Oakton side of 22181, Dunn Loring. The figures are Wolf Trap’s, the biggest piece.
- Median home built1980 Census
- Built before 1980about 5 in 10 Census
- Built since 2000about 1 in 10 Census
- Most homes aresingle-family houses, nearly all Census
- Heated withgas, about 7 in 10 Census
- Rentedhardly any Census
- 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 Vienna 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 Vienna.
Questions to ask anybody who looks at your tank, us included.
Did they test the shutoff valve before starting?
An old gate valve that won’t close turns a small repair into a big one. A tech who tests it first has planned for that.
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.

Questions
Water heater repair questions from Vienna.
Why does the flame on my Vienna water heater look yellow and lazy?
A yellow, flickering flame can mean poor air or a dirty burner, and an old chimney can add to it. It’s worth a check.
My shutoff valve won’t turn. What now?
Don’t force it. A stuck valve can snap. Call us and we’ll shut the water off at the street or replace the valve as part of the job.
How much is water heater repair in Vienna?
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.
