Oxon Hill's housing is mostly from the 1960s and 1970s, and homes with basements or lower levels here often depend on an aging sump pump. A plumber can sort out whether the problem is the pump, the switch, the check valve or the discharge line. Call the number on this page to be connected with a local plumber in Oxon Hill.

How the call works
When you call the number on this page, you are connected with an independent plumber who serves Oxon Hill. They will ask what you are seeing: water in the basement, a pump that will not stop running, a pump that will not start, or a sewage smell. Let them know whether it is happening right now, since a rising pit during a storm is handled differently from a pump that failed a test.
At the house, the plumber checks power and the outlet, lifts the float, listens to the motor and looks at the check valve and the line outdoors. Then they explain whether a repair will do or a new pump is the better choice, and whether a backup is worth adding.
Cost factors
- Switch, float or check valve repair versus pump replacement
- Ejector pumps for lower-level bathrooms, which take more time and parts
- Reaching a pit in a finished room or a tight townhouse utility closet
- Discharge changes so water leaves the yard instead of pooling by the wall
- Backup pump or alarm
- Calls at night, on weekends or during a storm
Local conditions
Oxon Hill is a close-in suburb along the Potomac, southeast of the District and next to National Harbor, with garden apartments, townhouses and single-family homes. The median home was built around 1972, so many pumps, basins and check valves are older than they should be. In townhouse rows, a pit may sit in a shared-wall lower level where a failure can affect the unit next door too.
WSSC Water handles water and sewer service here. For sewage overflowing from a manhole or the street, call WSSC at 301-206-4002. A clear-water pit and the pump in it are the owner's responsibility. Plumbing permits in Prince George's County come from WSSC Water, and replacing an existing pump generally does not need one.
Quick checklist before the plumber arrives
- Shut off the circuit if water is near outlets
- Clear the area around the pit
- Find the outdoor discharge and note whether it is blocked
- Note whether the water is clear or smells like sewage
- If you rent or belong to an HOA, check who handles the pump
