Triangle's housing is mostly newer, from the late 1990s on, and many homes have a basement sump pit with a pump that has never been serviced. When it fails, it is usually the float, the check valve, the power supply or the motor. Call the number on this page to be connected with a local plumber in Triangle.
Triangle conditions
Triangle sits in southeastern Prince William County, wedged between Dumfries, Prince William Forest Park and Marine Corps Base Quantico, and is home to the National Museum of the Marine Corps. The median home was built in 1999. That means many basements still have their original pump, which is now at the age when switches stick and motors wear out.
Prince William Water supplies Triangle from the Occoquan Reservoir and provides sewer service. Pumped groundwater should go outside, never into a floor drain or the sewer. For main breaks, outages or a sewer cleanout cap problem, Prince William Water's Emergency Dispatch is (703) 335-7990; customer service is (703) 335-7950. Some nearby areas are on a separate Virginia American Water system, so check your bill if you are unsure.
Triangle is unincorporated, so Prince William County's Building Development Division handles permits for new piping or an ejector system, at (703) 792-6930.
Choosing a fix
| Issue | Usual fix | Triangle note |
|---|---|---|
| Float sticks or switch fails | Replace the switch | Common on original pumps |
| Motor seized or loud | New pump | Many builder pumps are at this stage |
| Water falls back into the pit | New check valve | Cuts cycling and wear |
| Storms knock out power | Battery backup | No connection to drinking water |
| Water pools by the foundation | Longer or buried discharge | Stops the same water from returning |
Signs to watch
- A full pit and a silent pump
- A pump that hums or vibrates but moves no water
- Constant running in dry weather
- Wet carpet or drywall in the basement
- A basement bathroom that drains slowly or smells
Timing
Test the pump in spring, before summer storms, and again in late fall. A pump that sat idle all winter is the most likely to fail on the first heavy rain, and a five-minute bucket test catches most problems early. Fill the basin until the float rises, then watch for three things: the motor starts promptly, the pit empties completely, and water does not rush back in when the pump shuts off. If any of those fail, call before the next storm rather than during it. Winter adds one more check: after a cold night, make sure the outdoor end of the discharge line is not capped with ice.
