Capitol Heights sits on the DC line but is in Prince George's County, where WSSC Water, not DC Water, provides sewer service. Drain clogs inside the home are the owner's to fix, and the median home here dates to 1967. Call the number on this page to be connected with a local plumber in Capitol Heights.

Signs it is more than a simple clog
- Water rises in the tub when the toilet is flushed
- Sinks on different floors slow down together
- Sewage appears at a basement or utility room floor drain
- Plunging clears a toilet only for a day or two
- Gurgling from fixtures that are not in use
These point to the main building drain or the lateral. Hold off on laundry and showers until the line is open.
Drain conditions in Capitol Heights
Capitol Heights began as a 1904 subdivision just past the District's eastern edge, where Northeast and Southeast Washington meet, and it is served by the Capitol Heights Metro station. The median home was built in 1967, so many houses have drain lines from the mid-20th century or earlier. Cast iron drains scale with age and older laterals can let in roots, both of which trap grease and paper.
Because the town borders DC, homeowners sometimes assume DC Water and DC rules apply. They do not: WSSC Water provides water and wastewater service, and WSSC plumbing permits and rules apply. Right at the District line, confirm your provider on your bill. Sewage overflowing from a public manhole or street sewer goes to WSSC's emergency line at 301-206-4002. The Capitol Heights mailing address also covers surrounding unincorporated areas, which are WSSC customers too.
What affects the cost
- Clog location: a single trap versus the main line out to the street.
- Access: an outdoor cleanout saves time; otherwise the plumber may pull a toilet.
- Pipe age: older cast iron may need a descaling pass.
- Diagnostics: a camera inspection is extra but shows whether repair is needed.
- Repairs: a broken lateral turns cleaning into a permitted repair.
- Hour: nights and weekends usually cost more.
After you call
You are connected with an independent plumber who serves Capitol Heights. Say which drains are affected and whether the house has a basement cleanout. If the line must be repaired, the plumber files with WSSC Water, and the work must be done by a plumber registered with WSSC Water. For non-plumbing building permits, Prince George's County publishes which permits it handles in municipalities such as Capitol Heights.
