Lorton's housing is mostly newer, much of it built in the 2000s, and many of those homes have a basement sump pump that is now old enough to need attention. If water is rising, cut power to the area, protect the finished space and have a plumber check the pump. Call the number on this page to be connected with a local plumber in Lorton.
Lorton in brief
Lorton sits in southern Fairfax County along I-95 and Route 1, between Fort Belvoir and the Occoquan River, and the Laurel Hill area around the former Lorton Reformatory shares the Lorton postal name. Only about 17% of homes in the area predate 1980, and the 2000s were the biggest building decade. Fairfax Water supplies the water, and Fairfax County Wastewater Management runs the public sewer; the County's Noman M. Cole, Jr. Water Recycling Facility is in Lorton itself.
Right-now steps
- Turn off the circuit. Shut off power to the basement or the pump outlet at the panel if water is anywhere near it.
- Check for a simple stop. A tripped GFCI or a float hung up on the pit wall is common.
- Lift and move. Get rugs, furniture and stored items off the floor.
- Identify the water. Clear groundwater is a sump issue; sewage from a drain or basement bath means the ejector or the sewer.
- Report sewer backups. Fairfax County's 24-hour line, 703-323-1211, checks the public main.
- Call a plumber. Note what you hear from the pit and how fast it is filling.
Matching symptoms to causes
| What is happening | Probable cause |
|---|---|
| Pump does nothing | Power loss, bad switch or burned-out motor |
| Pump hums only | Blocked intake or stuck impeller |
| Pump short-cycles | Failed check valve or a float out of adjustment |
| Pump never stops | High groundwater or a switch stuck on |
| Outlet outside frozen | Ice in a flat discharge line |
| Odor from the pit | Open basin or dry floor-drain trap |
Cost considerations
- A float, switch or check valve repair versus a new pump
- Sump versus sewage ejector work
- Cleaning silt or debris from the basin
- Extending the discharge line farther into the yard
- Battery backup and alarm add-ons
- Any Fairfax County Land Development Services permit for new piping
- After-hours timing
Original pumps in homes from the 2000s are reaching the age where replacement often beats repeated repairs. If the pit has run hard through several wet springs, ask the plumber to check the check valve and discharge line at the same visit, since those parts age along with the pump and are easy to replace while the system is already open.
