In Manassas, a sump pump problem usually means a stuck float, a failed check valve, a tripped circuit or a motor that has worn out, and it tends to show up during a heavy summer storm. A plumber can test the pump, check the discharge and explain your options. Call the number on this page to be connected with a local plumber in Manassas.

From the first call to the fix
When you call the number on this page, you are put through to an independent plumber who serves Manassas. Tell them whether water is coming up right now, whether the pump is silent or running, and whether the pit collects groundwater or serves a basement bathroom. They will tell you whether to cut power to the circuit and what to move out of the way.
At the house, the plumber runs water into the pit, watches the float and motor, checks the check valve and follows the discharge pipe outside. Then you get a recommendation: repair the part that failed, replace the pump, or add a backup.
Cost factors
- Part repair versus a complete new pump
- Sump pump versus sewage ejector, which costs more to service
- Cleaning out a basin full of sediment or gravel
- New or longer discharge piping
- Battery backup or high-water alarm
- Permit work for new piping through the City
- After-hours or holiday timing
Manassas specifics
Manassas is an independent city, separate from Prince William County, with a historic Old Town and a large employer base led by Micron. The median home was built in 1985. Unlike its neighbors, the City runs its own water, sewer and electric utilities through City of Manassas Water & Sewer, and most of its water comes from Lake Manassas rather than the Potomac.
For a sewer or water emergency after hours, the City's line is 703-257-8353; Water & Sewer customer service is 703-257-8219 on weekdays. The City sewer handles household wastewater, so a sump discharge plugged into a floor drain or utility sink should be moved outdoors. City of Manassas Water & Sewer also runs a cross-connection program, so a water-powered backup pump is worth discussing with the City and the plumber; a battery unit avoids the question.
Inside city limits, permits come from City of Manassas Development Services at City Hall, 703-257-8200. Many Manassas mailing addresses fall outside the city, and those go to Prince William County instead.
Quick checklist before the visit
- Turn off the circuit if water is close to outlets
- Clear boxes and furniture away from the pit
- Locate the outdoor end of the discharge line
- Check your bill to see if you are a City utility customer
