Potomac's median home dates to 1977, and older farmhouses still stand among the subdivisions, so many houses are at the age where original copper starts to pinhole or galvanized sections rust through. A repipe replaces those supply lines, and on a property served by a private well it also covers the run from the pressure tank.

Potomac at a glance
Potomac grew from a farming community into an affluent suburb centered on Potomac Village, where Falls Road meets River Road. Most homes are on WSSC Water, but Montgomery County assigns every property a water and sewer service category, and some categories are set aside for private wells and onsite wastewater systems maintained by the owner. Large houses with long runs to distant bathrooms are common here, which affects how a repipe is planned. With a median build year of 1977, many homes still have their first copper lines, and some older farmhouses carry galvanized sections from early additions.
What to do now
- Confirm your water source. A WSSC bill means public water. No bill usually means a private well, and the plumbing starts at a pressure tank in the basement or utility room.
- Shut off and drain if a line has burst. Close the main valve, or on a well property, switch off the pump at its breaker, then open a low faucet.
- Photograph the exposed pipe. Pictures of the lines at the water heater, main valve and any open basement ceiling help the plumber plan before the visit.
- List past repairs. Note where leaks occurred and roughly when. Clusters point to a failing section; scattered leaks point to the whole system.
- Think about finishes. Decide who will repair drywall, plaster or millwork once the new lines are in.
Symptom guide
| Symptom | Likely cause |
|---|---|
| Pinhole leaks in different rooms over a few years | Copper thinning from the inside with age |
| Long wait for hot water at a far bathroom | Long, oversized or poorly routed hot line |
| Rust-colored water from older wings of the house | Galvanized pipe left from an original farmhouse or early addition |
| Pressure swings on a well property | Pressure tank or switch trouble rather than the pipe itself |
| Ceiling stain under an upstairs bath | Leaking branch line or a fitting at the shower valve |
Cost factors
- Square footage, number of bathrooms and total length of runs
- Finished basements, high ceilings and custom millwork that make access harder
- Copper or PEX, and whether a hot water recirculation line is added
- Reconnecting well equipment, treatment systems or irrigation
- Permit and inspection through WSSC Water
