Fairfax Station homes, many from the 1970s through the 1990s, often sit on wooded lots with basements that need a dependable sump pump. When the pump stops, the usual causes are power, a stuck float, a failed check valve or a worn motor. Call the number on this page to be connected with a local plumber in Fairfax Station.

Signs something is wrong
- Water in the basin and no sound from the pump
- A hum without any water leaving the pit
- Short bursts of running that never empty the basin
- Water falling back into the pit with a bang at shutoff
- Damp carpet, mildew or a musty smell in the lower level
- A pump that runs on and off for days after a storm
Fairfax Station conditions
Fairfax Station is a mostly residential, unincorporated community in southern Fairfax County that began in 1851 as a stop on the Orange and Alexandria Railroad. The median home was built in 1982, so many original pumps have already been replaced once and the replacements are getting older too. Finished lower levels are common, and a failed pump in one can mean real damage to flooring, drywall and stored belongings.
Fairfax Water is the water provider for county residents. Homes on public sewer are on Fairfax County's Wastewater Management system, where the owner maintains the private lateral and the County's 24-hour line, 703-323-1211, checks the main during a backup. Sump water should go outdoors, not into a floor drain or the sewer.
A water-powered backup pump connects to Fairfax Water's supply. Fairfax Water's cross-connection program, run with Fairfax County Land Development Services, handles backflow assemblies; its cross-connection department is at 571-722-7653. A battery backup avoids that question. New piping or an ejector for a basement bath goes through Land Development Services in PLUS.
