Riverdale, including the Town of Riverdale Park and nearby unincorporated areas, is served by WSSC Water, so homes here get pressure from the public main and do not have private well pumps. Pressure trouble in Riverdale's older streetcar-era houses usually comes from aging pipe and valves, and basement sump and ejector pumps are the pumps that wear out. Call the number on this page to be connected with a local plumber in Riverdale.

Signs and their usual causes
- Every faucet weak, and it has been getting worse for years: old steel or galvanized supply pipe
- A sudden drop for the whole block: WSSC main work or a break
- Low pressure at one fixture: a clogged aerator, showerhead or cartridge
- Water on the basement floor after a storm: sump pump failure
- Pressure tank cycling or a pump running constantly: only if your lot has its own well, which would be unusual here
Local conditions in Riverdale
Riverdale is a postal name covering the incorporated Town of Riverdale Park plus neighboring unincorporated areas such as Riverdale Heights. It is an older streetcar-suburb area just south of College Park along US 1, about 6 miles from downtown Washington, with the Riversdale mansion, Riverdale Park Station and a MARC stop. The median home in Riverdale Park was built in 1957.
WSSC Water supplies water and sewer service and disinfects with chlorine. Homes of this age often still have original galvanized lines, and WSSC's What's Your Pipe Type? program helps customers identify and replace lead service lines on both the utility and customer portions. Part of the service line is owned by WSSC and part by the customer, and WSSC asks customers planning to replace their portion to notify it first. For water or sewer emergencies, WSSC's Emergency Service Center is at 301-206-4002.
What affects the cost
- Whether a valve repair solves it or older supply pipe needs replacing
- Coordinating a service line replacement with WSSC
- Access through plaster walls and finished basements
- Sump or ejector pump type and any backup system
- Permits: most plumbing projects in WSSC territory, including service line repairs, need a plumber holding a WSSC license and a permit through WSSC ePermitting; building permits come from the county or, inside town limits, check with the Town of Riverdale Park
What happens when you call
You reach a free referral service, not a plumbing company, and get connected with an independent plumber who works in Riverdale and Riverdale Park. Describe the age of the house, whether pressure fell suddenly or slowly, and whether a pump in the basement is involved. If the plumber suspects old pipe, they will usually start by checking the material where the line enters the house.
