When water is spraying or a drain is overflowing in a Centreville house, the first move is to shut the main valve; a smell of gas means leaving before you make any calls. After that, call the number on this page to be connected with a local plumber in Centreville.

Signs it's an emergency
- A supply line or fitting has let go and water is spreading across the floor
- Sewage rising in a basement shower or floor drain
- Water seeping from the bottom of the water heater
- No water anywhere in the house, with no outage on the street
- A gas odor near an appliance or the meter
A dripping faucet or a toilet that runs on and off can wait. Anything that keeps soaking carpet, cabinets or a finished basement should not.
Centreville's water, sewer and gas
Fairfax Water supplies Centreville, drawing on the Potomac River and the Occoquan Reservoir; its customer service number is 703-698-5800. Fairfax Water owns the meter, but the underground line from the meter to the main shutoff valve in the house is the homeowner's plumbing. In homes from the 1970s an inside meter is common, and Fairfax Water's ownership there covers only the meter and its remote reader.
Fairfax County runs the public sewer mains. If sewage is coming up, call the county's 24-hour line at 703-323-1211 first so a crew can check the main. If the main is clear, the private lateral from your house to the main is the owner's responsibility, and that's where a plumber comes in.
Gas is Washington Gas. Smell gas, leave the house, then call 911 and 844-WASHGAS (844-927-4427), option 1, from outside.
Much of Centreville was built around Interstate 66, Route 29 and Route 28 in the 1980s and 1990s, and the median home dates from 1991. Copper and plastic supply piping is the norm, so emergencies tend to come from failed supply hoses, water heaters and valves rather than corroded pipe.
What moves the price
- Timing. After-hours and weekend calls usually cost more.
- Access. Pipes behind finished basement walls take longer to reach.
- Scope. A new valve is small; a new water heater is a larger job.
- Permits. In Fairfax County, a like-for-like gas water heater swap with no new gas piping uses a Household Appliance permit, and new gas piping needs a Residential Plumbing permit.
After you call
You'll be put through to an independent plumber who takes urgent jobs in Centreville. Say what failed, whether the main is closed, and the nearest main road. Ask how after-hours pricing works. Timing depends on the hour, so no arrival time is promised.
