Clifton's historic houses, about half of them from 1940 or earlier, sit on wooded lots with private wells and onsite wastewater systems, so a sump pump here has to discharge carefully and back up sensibly. When it quits, the usual causes are power, the float switch, the check valve or the motor. Call the number on this page to be connected with a local plumber in Clifton.
Signs your pump needs help
- Water standing in the pit after rain and no motor sound
- A humming pump with nothing coming out of the discharge
- Rapid on-off cycling
- Water seeping through old foundation walls or at the floor joint
- Musty air, efflorescence or mold in the basement
- A pump that shuts down whenever the power flickers in a storm
What makes Clifton different
Clifton is a tiny historic village in southwestern Fairfax County, a National Historic District with wooded single-family lots, and its median home was built in 1940. The Town has no water system, so homes rely on private wells, and new houses must have room for both a well and an onsite wastewater field. Public sewer is available only to existing buildings that meet Fairfax County guidelines, and connecting requires County approval.
That shapes how pumps should be set up. Sump water should discharge to the surface, well away from the drain field and the well head, because extra groundwater can overload an onsite system. A water-powered backup pump depends on water pressure, and on a well that pressure disappears when the power goes out, so a battery backup is the better fit. Older stone or block foundations can also let in more water than a small pump can handle in a heavy storm.
For permits, Fairfax County Land Development Services issues them, but the Town's Mayor or a designee must sign the application first. For interior-only work, the Town can provide a letter to the County.
Cost factors
- A switch or valve repair versus a full pump
- Sump pump or sewage ejector feeding the onsite system
- A long discharge route that avoids the well and drain field
- Upgrading pump capacity for an older foundation
- Battery backup sized for longer outages
- Town sign-off and County permit steps
- Storm or after-hours timing
