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 Springfield
Ask what’s at the main in Springfield and the answer changes by neighborhood. North Springfield’s median home is from 1957, Kings Park’s from 1966, West Springfield’s from the early 1970s, Newington Forest’s from 1984. A house on one of the first two blocks was plumbed before most builders put a reducing valve in at all, so the first thing to look for there is whether anyone ever added one.
Fairfax Water promises 20 psi at the main and doesn’t promise more, and the valve that handles the rest belongs to the owner. In the older ranches that often means the house has taken whatever the street sent for sixty years, and the pipes inside have taken it too. In those houses we’re as likely to recommend installing a first valve as replacing one, and a gauge reading is how you decide.
Newington Forest and parts of West Springfield are the other kind: 1980s and 90s townhouses, about half of Newington Forest, with a builder valve near the water heater. The row turns the question around. If the neighbor on either side replaced theirs and yours is the last original, the one in your wall has the same years on it, and nobody is the wiser until it creeps.
The Springfield CDP is also more than a quarter condos and apartments, plus a good number of rentals. In a building, the valve at the base of the riser may feed every unit, and you can’t touch it. If your unit has a thump or a drip and you rent, send your landlord a photo of the gauge reading, not a description of the noise. That’s a repair they can’t wave off.

By the numbers

The signs
A toilet that runs on after the flush, or a faucet that drips whatever washer goes in, can be pressure doing the damage. In a 1960s ranch the fixtures are old enough that people blame them first. A gauge reading shows which it is.
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.
When every faucet in the house went weak at once, the valve at the main is the first suspect. They wear out and can fail closed, and a stuck valve feels exactly like the water company turned you down.

Choosing who fixes it
Questions to ask anybody who quotes you a valve, us included.
In an older Springfield house the answer may be that nothing is there to replace. A plumber who tells you that, with a reading in hand, is the one to hire.
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
Possibly not. Many houses that old were built without one, and a valve was added only if someone had trouble. Look for a bell-shaped brass valve with a bolt on top near the main shutoff. If there isn’t one, a gauge on the hose bib tells you what the house gets.
Sometimes. Where a building valve feeds every unit it belongs to the association, and the pipes past your unit’s shutoff are yours. Ask the management office which you have before you pay for a valve you can’t reach.
$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.
