During a Greenbelt plumbing emergency, close the main water shutoff to limit the damage, and if you smell gas, leave first and call from outside. The City sends water and sewer emergencies to WSSC Water, while problems inside your home or co-op unit go to a plumber. Call the number on this page to be connected with a local plumber in Greenbelt.

What happens when you call
The number on this page connects you with an independent plumber who takes emergency work in Greenbelt. Expect a few questions: what failed, whether water or sewage is still moving, whether the main is off, and where you are. Mention the section of town, such as Old Greenbelt, Greenbelt East, Greenbelt West or Springhill Lake, plus a cross street off Greenbelt Road or Kenilworth Avenue. Ask how after-hours and trip charges work before anyone sets out. No arrival time is promised; it depends on the hour and the plumber's schedule.
What changes the price
- Time of day. Evening, weekend and holiday calls usually cost more.
- Shared walls. Townhouses and attached co-op homes can hide pipes behind finished walls or in a neighbor's space, which adds time.
- Scope. Stopping a leak is one job; replacing a water heater or a drain section is another.
- Permits. WSSC Water issues plumbing and gasfitting permits, and Greenbelt adds its own City permit for projects that need a county building permit.
Local conditions in Greenbelt
Greenbelt began as a New Deal planned community, and its historic core around Roosevelt Center dates to the late 1930s. The median home was built in 1976, so many houses have original plumbing from the 1930s through the 1970s: old shutoff valves, galvanized or copper supply lines and cast iron drains are all possible. WSSC Water supplies water and sewer service, and the City directs residents to the WSSC Emergency Services Center at 301-206-4002 for breaks and overflows in the street.
WSSC water is disinfected with chlorine, and its tap analysis reports hardness averaging about 140 mg/L from the Potomac plant and about 64 mg/L from the Patuxent plant; which plant serves an address varies. That scale can shorten the life of water heaters and valves over the years.
Washington Gas serves the city. For a gas smell, leave, then call 911 and Washington Gas at 844-WASHGAS (844-927-4427) OPTION 1 from outside.
Before the plumber arrives
- Close the main and open a low faucet to drain the pressure.
- Turn off the gas valve or breaker to a leaking water heater.
- Stop flushing and running water if drains are backing up.
- Move belongings off wet floors and take photos for insurance.
- If you live in a co-op or condo, let management know.
