When a pipe bursts in a Fairfax home, close the main water valve and keep out of any water that has reached outlets or cords. A plumber can find the rupture, replace the failed section and test the line. Call the number on this page to be connected with a local plumber in Fairfax.

Fairfax in brief
The City of Fairfax is an independent city, legally separate from Fairfax County, and much of the area with a Fairfax mailing address lies outside city limits in the county. Fairfax Water supplies both. The median home in the area was built in 1967, so many houses have original copper or steel supply lines that have seen more than fifty winters.
Pipe that has sat in a wall that long tends to give out first at joints and valves, and a sharp freeze followed by a thaw is often what finally opens a weak spot. Outdoor faucets on older houses are frequently not frost-free, so the pipe just behind them is especially exposed.
First steps
- Shut the main. Look where the line enters the house, usually in the basement or a utility room.
- Turn off the water heater. Breaker off for electric, pilot for gas.
- Avoid wet electrical areas. Keep clear of outlets, cords and the panel if water has reached them.
- Drain what is left. Open a faucet on the lowest floor.
- Protect belongings. Move furniture and electronics, and lift rugs.
- Photograph everything before cleanup for the insurance claim.
- If gas smell appears, leave and call 911 and Washington Gas at 844-WASHGAS (844-927-4427), option 1, from outside.
Symptoms and causes
| Symptom | Likely cause |
|---|---|
| Rusty water when the main is reopened | Aging galvanized steel near the break |
| Ceiling drip in a room below a bath | Split supply, failed valve or loose fitting |
| Basement wall wet under an outdoor faucet | Frozen spigot line cracked inside the wall |
| Whole-house pressure gone | Major rupture on the main supply |
| Wet lawn strip between street and house | Leak in the private service line |
Cost factors
- Age and material of the pipe around the break
- Opening plaster or finished drywall versus exposed joists
- Extra cracks found when pressure is restored
- Yard digging for a service line
- After-hours scheduling
- Permits: inside the city, plumbing permit applications go to the City's Code Administration at 703-385-7830; county addresses go to Fairfax County Land Development Services
For a problem at the meter or the street, Fairfax Water's line is 703-698-5800. If the trouble is sewage backing up rather than a pipe break, the City's wastewater services after-hours line is 703-385-7924, and county addresses call 703-323-1211.
