When a Capitol Heights home has a burst pipe or a drain backing up, close the main water valve right away, and if you smell gas, leave before calling. Even though the town borders Washington, it's in Prince George's County, so WSSC Water, not DC Water, runs the water and sewer. Call the number on this page to be connected with a local plumber in Capitol Heights.

Problems that need a call now
- A pipe leaking faster than a bucket can catch it
- Toilets or tubs filling with sewage
- Water seeping from under a water heater
- Water stains spreading across a ceiling
- Any smell of gas inside the house
If it's a slow drip or a drain that's sluggish but still working, a weekday visit is fine. When in doubt, close the main first; it buys time to decide and limits damage either way.
Capitol Heights conditions
Capitol Heights began in 1904 as a subdivision just beyond the District's eastern edge, where Northeast and Southeast Washington meet. The median home was built in 1967, so many houses have original drains, supply lines and valves that have been in place a long time. The Capitol Heights mailing address also covers unincorporated areas around the town.
Because the town is in Maryland, WSSC Water supplies its water and wastewater service. Report main breaks and overflowing manholes to WSSC at 301-206-4002. WSSC owns the service line from the main to the property line, and the owner has the rest. Right at the District line, check your bill to confirm which utility serves the address.
Washington Gas serves the area, though some county addresses are on BGE. If you smell gas, leave the area, then call 911 and the Washington Gas Emergency Leak Line at 844-WASHGAS (927-4427), option 1, from a safe place.
Cost factors
- Time of the call. After-hours visits generally cost more.
- Age of the system. Decades-old drains or supply pipe may need a bigger section replaced.
- Access. Pipes inside finished walls or under basement floors take longer to reach.
- Maryland rules. WSSC Water rules apply here, not the District's. WSSC issues plumbing permits, a water heater replacement needs one, and gas work must be done by a professional holding a WSSC license.
What to expect when you call
You'll be connected with an independent plumber who handles urgent work in Capitol Heights. Give the address and a landmark such as the Capitol Heights Metro station, Central Avenue or Marlboro Pike, say whether the main is closed, and describe what's happening. Ask about after-hours pricing before the visit. No arrival time is promised.
