What it costs
From the same price book as our plumbing price list: the valve, the fittings, setting it with a gauge and checking the house afterward. More on what causes it in our low water pressure guide.

Where you land in the range is mostly where the valve sits and what it’s attached to: a valve right at the main shutoff in an open basement is the easy end, one behind a finished wall or on corroded pipe is the other.
When a new valve brings the pressure down, the water heater can no longer push its expansion back into the street, so we check for an expansion tank on the same visit and tell you if the house needs one.
What’s different in Burke
Nearly half of Burke’s homes went up between 1980 and 1999, and the median owner home is from 1979. Fairfax Water leaves the reducing valve on your side of the meter, which means the valve in a typical Burke house is the one the builder bought in bulk, four decades back. Brass valves are known to wear their seat and spring over the years, and the usual sign is a number that creeps up, not a sudden failure.
Burke Centre is where finding it gets interesting. A lot of its townhouses are in rows around the lakes and walking paths, with the water line coming in at one end of a slab or a crawl-height utility room, and the valve a foot or two past the meter loop. Open the closet, follow the pipe from the wall, and look for the brass bell with the bolt on top before the water heater, not after it.
The older streets around Lake Braddock are a different guess. Houses from the early 1970s may carry a valve that was added later, or never had one, and a handful may still have a gate valve at the main that is only a shutoff. A gate valve at the wall doesn’t hold anything back. If your faucets thump and there’s no bell-shaped valve anywhere along the line, the house may simply have no regulator, and Fairfax Water’s pressure goes straight to your taps.
Burke runs electric about as often as gas, so plenty of tanks here are electric, and an electric tank heats in the night like any other. A relief valve that drips in the morning is a clue about the house pressure, not about the tank. We read the gauge cold, then read it again after the tank has been heating, since that second number is the one that tells on a weak valve.
Neighborhood by neighborhood
Census figures for the owner-occupied homes in each place, and what usually sits at the main shutoff in houses like them.
| Place | Median home built | Most homes are | Heated with | What’s usually at the main shutoff |
|---|---|---|---|---|
| Burke | 1979 | single-family houses, about 6 in 10 | gas, about 6 in 10 | An old gate valve, often no reducing valve. |
| Burke Centre | 1982 | townhouses, about 5 in 10 | electricity, about 7 in 10 | The builder’s original reducing valve, worn. |
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
The signs
An electric tank in a Burke Centre closet warms up overnight, and if the valve upstream is tired, the water has nowhere to go but out the relief valve. A damp drain pan or a wet spot under the discharge pipe is worth a gauge reading.
Many houses built on public water since the 1980s came with a valve right after the main shutoff. A lot of those are the originals, and a valve that old has usually stopped holding the pressure where it was set.
A thud in the wall when the washer or a faucet closes is water hammer, and high pressure makes it worse. So does a toilet that keeps refilling, or faucets that drip no matter how many washers go in.

Choosing who fixes it
Questions to ask anybody who quotes you a valve, us included.
In a Burke Centre townhouse the valve can sit behind a panel or a shelf. A plumber who looks first, and tells you if the house never had one, is quoting the right job.
A valve quoted without a pressure reading is a guess. Ask what the house reads now, static and with water running, and what they’ll set it to.
A new valve changes how the water heater handles expansion. The plumber who checks for an expansion tank is the one who saves you a dripping relief valve next month.

Questions
Many do by now, because a valve gets added when an old one fails or a plumber sees high pressure. A reading at the hose bib answers it. If it’s over 80 psi, the Virginia Residential Code calls for one.
In a townhouse row each home has its own line from the street, so the valve is yours. In a condo building it may be a building valve, and that one belongs to the association.
$500 to $1,000, with the valve, the fittings and setting it with a gauge in that number. Where you land depends on where the valve sits and the pipe it’s on.
Most houses run well somewhere around 50 to 70 psi. The Virginia Residential Code calls for a reducing valve once the street pressure tops 80 psi. We read it with a gauge on a hose bib so you know your own number.
