Fairfax Station is a mostly residential, unincorporated part of southern Fairfax County, so commercial work here tends to mean churches, community association buildings, small offices and larger properties rather than big retail. Fairfax County issues permits, and Fairfax Water and County sewer serve much of the area. Call the number on this page to be connected with a local plumber in Fairfax Station.

Signs a non-residential property needs a plumber
- A fellowship hall or church kitchen drain that backs up after large events
- An association pool house or clubhouse with running or clogged toilets
- An irrigation backflow assembly that missed its yearly test
- Water heaters that can't keep up with occasional heavy use
- Low pressure or a wet spot along a long service line
- Pipes in an unheated outbuilding that froze over the winter
Local conditions in Fairfax Station
Fairfax Station began in 1851 as a stop on the Orange and Alexandria Railroad and is now a car-dependent, mostly residential area around Ox Road, the Fairfax County Parkway and Burke Lake Park, with a median home built in 1982. Lots tend to be larger, so service lines and laterals can be long.
Fairfax County lists Fairfax Water as the provider for its residents, drawing on the Occoquan Reservoir and the Potomac River, though whether a particular property is on public water and sewer is worth confirming on the bill. Fairfax Water owns the meter, and the homeowner or property owner owns the service lateral from the meter to the building. Where public sewer exists, the County runs it and the owner maintains the private lateral (703-323-1211 for backups). Under Fairfax Water's cross-connection program, run with Fairfax County Land Development Services, irrigation backflow assemblies are tested when installed, every year and after repair or replacement (571-722-7653).
Permits come from Land Development Services through PLUS, and gas water heater or furnace replacements need a permit even like-for-like. Washington Gas serves most of the county, but service on every street isn't guaranteed. If anyone smells gas, get outside, then call 911 and Washington Gas at 844-WASHGAS (844-927-4427), option 1, or your propane supplier if that's what the building uses.
Cost factors
- Length of the water service or sewer lateral on a large lot
- Whether the building is on public utilities or private systems
- Backflow parts and the retest
- County permit steps
- Scheduling around services, events or residents
