A Capitol Heights water heater that leaks, rusts or can't keep up is usually best replaced. Although the town borders the District, it's in Prince George's County, so WSSC Water rules apply: water heater replacements need a WSSC permit and inspection. Call the number on this page to be connected with a local plumber in Capitol Heights.

Signs the heater is at the end
- Water on the floor or a rusted base
- Rust-colored water from hot taps
- Popping and banging during heating
- Showers that turn cold quickly
- Repeated pilot or ignition problems
Capitol Heights conditions
Capitol Heights began as a 1904 subdivision just past the District's eastern edge, and its median home dates to about 1967. Many houses have original or partly updated plumbing, so expect the plumber to check the shutoff valve, the flue and the gas connector before quoting. Right at the District line, confirm your utility by address. WSSC Water, not DC Water, supplies water and sewer service in the town, and DC permit rules don't apply here. That also means the WSSC permit and inspection process, not the District's, governs a water heater swap. A plumber who works on both sides of Southern Avenue will know the difference, but it's worth confirming.
Many homes near the Metro station and along East Capitol Street have basements with older chimneys. If the furnace was replaced with a model that vents out a side wall, the chimney may be oversized for the water heater alone and draft poorly. The plumber may suggest a liner, a power-vent heater or an electric unit.
WSSC disinfects with chlorine and adds a corrosion inhibitor that coats pipes on customer property. Washington Gas serves the area, though BGE covers some county addresses. If you smell gas, leave the house first. Then call 911 and Washington Gas at 844-WASHGAS (927-4427), option 1, from outside.
What affects the price
- The new heater's fuel, capacity and efficiency
- Venting changes and gas connector updates
- Replacing aged shutoff valves or fittings
- Expansion tank and drain pan requirements
- Access to a basement or utility room
- WSSC permit and disposal of the old tank
What happens next
You'll be connected with an independent plumber serving Capitol Heights. Give them the heater's size, fuel and location, and say whether it's leaking. Ask that each quote spell out the permit, code updates and removal, so the prices compare on the same terms. If a leak is spreading, close the cold supply valve above the heater before anything else.
