Chevy Chase homes get their water from WSSC Water, so a private well pump is not a realistic part of the picture here. Weak pressure in these older houses usually traces to aging supply pipe, stuck valves or a leak, and occasionally to a booster pump. Call the number on this page to be connected with a local plumber in Chevy Chase.

Signs it is time to call
- Showers that weaken when someone runs a tap elsewhere
- Low flow on upper floors only
- Brown or rusty water when a tap first opens
- A water bill rising with no change in use
- A booster pump, if you have one, that clicks rapidly or runs nonstop
- A main shutoff that will not turn fully
Local conditions in Chevy Chase
Chevy Chase began in the 1890s as a streetcar suburb along Connecticut Avenue, and its age shows in the plumbing. In ZIP 20815, roughly two-thirds of homes were built before 1980, and more than 2,600 date to 1939 or earlier. Houses that old may still have galvanized supply pipe that rusts shut from the inside, original valves and service lines that have been patched over the decades. Those are the usual reasons pressure drops here, not a pump.
All of the area, from the Town of Chevy Chase to Chevy Chase Lake and Friendship Heights, is on WSSC public water. WSSC is responsible for its mains and meters; the owner's pipe runs from the property line into the house. A pit pump in the basement is a sump pump, which handles groundwater rather than your supply.
What affects cost
- Pinpointing the cause, whether a fixture, a valve, a section of galvanized pipe or the service line
- Access through finished basements, plaster walls and mature landscaping
- Whether partial pipe replacement is enough or a fuller repipe makes more sense
- Permits: WSSC Water Permit Services handles plumbing permits, and the Town of Chevy Chase requires its own permit for larger projects once the County permit is issued
What happens when you call
You will be connected with an independent plumber who works in Chevy Chase. This line is a referral service and does not send its own crew. Tell the plumber the age of the house if you know it, whether the problem is in one spot or throughout, and whether there is a booster pump. A good first visit tests pressure at the main, checks the pressure-reducing valve and shutoff, and looks at visible pipe to see whether galvanized sections remain.
