Capitol Heights borders the District, but it's in Prince George's County, so WSSC Water, not DC Water, provides sewer service and WSSC rules apply. A blocked, cracked or root-damaged line between a Capitol Heights house and the main is repaired by a plumber holding a WSSC license. Call the number on this page to be connected with a local plumber in Capitol Heights.

Signs of a sewer line problem
- Several drains back up at once, often starting at the lowest one
- Toilets bubble when the bathtub drains
- A floor drain overflows during laundry
- Drains clear after plunging, then slow again within days
- A persistent sewage smell outside near the foundation
Local conditions in Capitol Heights
Capitol Heights began as a 1904 subdivision just beyond the District's eastern edge, where Northeast and Southeast Washington meet, and was incorporated as a town in 1910. The median home here was built around 1967, with older houses dating back much further. Lines from those decades are usually cast iron or clay, and they tend to fail through corrosion, cracked joints and roots. The Capitol Heights mailing address also covers unincorporated areas around the town, which follow the same county and WSSC rules.
Because the town sits right on the District line, it's easy to assume DC Water is the utility. It isn't: WSSC Water provides water and wastewater service here, and the sewer emergency line is WSSC's, 301-206-4002. For a property right at the line, confirm the provider on your bill. In Prince George's County, WSSC also issues plumbing permits and requires sewer service line repairs and replacements to be done by a plumber holding its license.
What affects cost
- Pipe material, condition and the length of the bad section
- Depth, plus what's on top: lawn, steps, a walk or a parking pad
- Whether the line can be lined or must be excavated
- Access through a cleanout, or adding one
- The WSSC Water permit and inspection
Narrow lots and older homes set close together can limit where equipment fits, which sometimes makes trenchless lining more practical than digging.
What happens when you call
You'll be connected with an independent local plumber who works in Capitol Heights. Let them know which drains are backing up, when the house was built and whether the line has had work before. The plumber will usually relieve the blockage, run a camera through the line, locate the damage and its depth, and then explain the options. Until then, stop running water and keep people away from any backup.
