If a pipe bursts or a drain backs up in a Fort Washington home, close the main shutoff first, and if you smell gas, get out before calling anyone. WSSC Water handles mains and street sewers here; a plumber handles the house and the lines on your lot. Call the number on this page to be connected with a local plumber in Fort Washington.

Fort Washington stretches along the Potomac in southern Prince George's County and stayed rural until about 1960. Today it is mostly suburban, with neighborhoods like Tantallon and Fort Washington Forest, riverfront homes and marinas. The median home was built in 1980, so many houses are reaching the age when original water heaters, valves and supply lines start to wear out. WSSC also adds orthophosphate to coat the inside of pipes, including those on the customer's side, but no treatment stops a fitting from failing with age or a pipe from splitting in a hard freeze.
Steps to take now
- Shut the main. It's usually in the basement or a utility room where the line enters from the street. Turn it fully clockwise.
- Relieve the pressure. Open a faucet on the lowest level to drain what's left in the pipes.
- Handle the water heater. If it's leaking, close its cold supply and turn the gas control to off or switch off its breaker.
- Leave for any gas smell. Go outside, then call 911 and Washington Gas at 844-WASHGAS (927-4427), option 1. If your bill comes from BGE instead, use BGE's number on that bill.
- Call WSSC for street problems. A break in the road or an overflowing manhole goes to WSSC Water at 301-206-4002.
- Document it. Take photos of the damage before cleanup for your insurer.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Water dripping through a ceiling below a bathroom | Failed supply line, valve or drain joint |
| Basement drain overflowing during heavy rain | Overloaded or blocked sewer lateral |
| Puddle beside the water heater | Tank failure or relief valve discharge |
| Spraying pipe after a freezing night | Pipe split by ice in an exterior wall or garage |
| Irrigation backflow device leaking in spring | Freeze damage to the assembly |
Cost factors
- When you call. Nights and weekends usually cost more than a weekday slot.
- Access. Finished basements and larger riverfront homes can mean longer runs of pipe to trace.
- Scope. Stopping a leak is quicker than replacing a water heater or a sewer section.
- Permits and qualifications. All plumbing permits in the county come from WSSC Water, and gas appliance replacements must be done by a WSSC-qualified gasfitter. Irrigation backflow assemblies are tested yearly by a certified cross-connection technician.
