A shutoff valve that won’t turn
Under a sink in a house from 1990, the stop valve is often seized with scale. Don’t force it. An old valve can snap off in your hand and turn a drip into a flood. Use the main shutoff and call us.

Most repairs are one section of pipe: the split or pinhole cut out and a new piece put in. Where the pipe sits decides most of the price. Exposed in a basement ceiling is the low end; inside a finished wall is higher, and we tell you before the drywall comes open.
With Comfort+ membership, any repair is 15% off, and every year includes a plumbing safety inspection that looks at the supply pipe you can see.
What’s different in Centreville
Centreville’s townhouses are three decades in, and the shutoff valves fail before the pipes do.
Close to seven in ten Centreville homes went up between 1980 and 1999, and nearly half are townhouses, so the typical house here has been plumbed for more than thirty years. At that age the pipe is often fine and the parts around it are not: the stop valve under the sink nobody has turned since the builder left, the toilet supply line, the washing machine box, the hose bib.
Fairfax Water says its water here is moderately hard to hard, five to ten grains per gallon, pulled from the Potomac and the Occoquan Reservoir. Hardness leaves scale, and scale is what freezes an old stop valve in place. So when a fixture finally leaks, you often can’t shut the water to just that fixture, and a small drip turns into a trip to the main shutoff.
Those same years overlap the polybutylene window. Not every Centreville house got the gray plastic, and some townhouse rows were plumbed in copper, but if the pipe near your water heater is gray with metal crimp rings, we check every joint on that run. It rarely fails mid-pipe. It fails where it connects.
In a townhouse row the supply lines come to each unit separately, but the walls are shared, so a stain on a party wall can start next door. Tell us which wall, and which neighbor, and we’ll start with the water heater closet and the stops on that side of the house. Detached houses here leak most often at the washing machine box and the outside spigots.
By the numbers
Centreville houses, by the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
Centreville
- Median home built1990 Census
- Built before 1980about 1 in 10 Census
- Built since 2000about 2 in 10 Census
- Most homes aretownhouses, about 5 in 10 Census
- Heated withgas, about 7 in 10 Census
- Rentedabout 3 in 10 Census
- A lot of houses here went up while polybutylene supply pipe was in use, about 1978 to 1995. It fails at the fittings, so one leak is a reason to check the rest.
- Townhouses share walls, so water showing on your side can start on your neighbor’s. The meter test tells you whose it is.
What you’d notice
How a pipe leak in Centreville usually shows up.
Grey plastic pipe at the water heater
Polybutylene, often stamped PB, went into houses from about 1978 to 1995. It tends to fail at the fittings without much warning, so a drip at one joint is a reason to look at the rest.
A stain spreading on the ceiling
A brown ring under a bathroom, or a soft spot in the drywall, is water that’s been finding its way down for a while. A supply pipe leaks all the time; a drain only leaks when somebody runs water upstairs, and that difference tells us where to look first.
The meter moves with every tap off
Turn everything off and watch the water meter for ten minutes. If the dial or the little leak indicator still moves, water is going somewhere, inside a wall, under a slab or out in the yard.

Before the first hard freeze
Keep pipes in Centreville from freezing this winter.
A pipe usually bursts in the hours after a cold snap, when the ice inside it thaws and the split starts to run. Five things to do before it gets that cold, then call us if something already looks wrong.
- 1
Hose off, outside spigot shut inside
Disconnect every garden hose. A hose left on traps water in the spigot, and that’s the most common split we see. If the spigot has a shutoff inside the house, close it and open the outside tap to drain it.
- 2
Cabinet doors open on outside walls
A kitchen or bathroom sink on an outside wall gets the coldest air in the house. On the coldest nights, open the cabinet doors so room heat reaches the pipes, and let that tap drip.
- 3
Crawl space and garage closed up
Close crawl space vents and the garage door for the winter. Pipes that run through a crawl space, a garage ceiling or an unheated room over the garage are the ones that freeze first.
- 4
Know where the main shutoff is
Find it now, before you need it: usually where the water line comes through the basement or crawl space wall, near the meter or the water heater. Make sure it turns. When a pipe bursts, that valve is the difference between a mop and a contractor.
- 5
Going away? Leave the heat on
Keep the thermostat at 55 or higher while you’re gone, and ask someone to look in if a cold snap comes. A frozen pipe that thaws with nobody home runs for days.
Find a pipe that’s frozen, or water where it shouldn’t be? Shut the main off and call us at (703) 997-9757. A diagnosis visit is $49, or $250 after hours, and you get the repair price before we cut into anything.
Your pipes, your paperwork
Whose pipe is leaking in Centreville.
Fairfax County
In Fairfax County the homeowner owns the whole sewer lateral, from the house to the county main, including the stretch under the street. Replacing it takes a county plumbing permit, plus a VDOT permit under a state road. Source.
Fairfax Water promises 20 psi at the main and no uniform pressure, and the pressure reducing valve on your side of the meter is yours to buy and keep up. Over 80 psi, the Virginia Residential Code calls for one, and an expansion tank with it. Source.
Our Virginia Class A contractor license, 2705192276, is on the side of the van.
Choosing who fixes it
How to pick a plumber for a leak in Centreville.
Questions worth asking anybody who comes out, us included.
Will they replace a seized stop valve while the pipe is open?
If the valve under a leaking fixture won’t turn, the next leak there has no off switch. Swapping it while the line is already apart is a few minutes’ work, and it saves a main shutoff call down the road.
Is the plumber licensed in Virginia?
Anyone can check on the state’s license lookup. Ours is Virginia Class A contractor license, on every van.
Will they find the leak before they open a wall?
A good leak call starts at the meter and the shutoffs, then narrows it down with pressure and moisture readings. The drywall comes open in one spot, not five.
Do you get the price before the work?
Every repair on our list has a range, and you hear where yours lands before anything is cut. If someone won’t say until the job is done, keep looking.

Questions
Leak and burst pipe questions from Centreville.
Is hard water the reason my Centreville pipes leak?
Not directly. Scale doesn’t eat through pipe the way acid does. It jams valves, clogs aerators and shortens a water heater’s life, and the tank and its fittings are where a Centreville leak often starts. Fairfax Water’s own FAQ calls its water moderately hard to hard.
My water bill went up and nothing is dripping. Is there a leak?
Possibly. Shut every tap and appliance off and read the meter, then read it again after an hour. If it moved, water is going somewhere. A toilet flapper that doesn’t seal is the usual cause. Then check the hose bibs and the washer box, and call us if the meter keeps moving.
There’s a stain on the ceiling of my finished basement. What’s above it?
In a Centreville townhouse, usually the first-floor bath or kitchen, where the supply lines and the drain run between the joists. We cut a small access panel at the stain, find the wet fitting and patch the opening so it can be painted. Shut the stops under the fixtures above while you wait.
What do I do first when a pipe bursts in Centreville?
Shut off the main water valve, then turn off the water heater (gas to pilot, or the breaker for electric). Open a faucet at the lowest point of the house to drain what’s left in the pipes. Then call (703) 997-9757: a person answers day or night, and our emergency plumbing team is on 24/7.
How much does it cost to fix a leaking pipe in Centreville?
A plumbing diagnosis visit is $49, or $250 after hours. Finding a leak you can’t see is $200 to $500, and most water pipe repairs run $450 to $650. You get the number before we start.
Ready when you are
