Poolesville runs its own water system from Town wells rather than WSSC Water, and its median home was built in 1985, so many houses are on original supply lines that are reaching the age of repeat leaks. A repipe replaces those lines with PEX or copper when repairs stop holding. Call the number on this page to be connected with a local plumber in Poolesville.
Poolesville in brief
Poolesville is a small historic town in western Montgomery County, surrounded by the county's Agricultural Reserve. The Town operates its own groundwater wells, drawing from the New Oxford Formation aquifer at depths of roughly 285 to 800 feet, and disinfects with chlorine. It also runs its own wastewater treatment plant. Some properties in and around town are on private wells and onsite systems instead.
What to do now
- Close the indoor shutoff. The Town says most homes have one where the service line enters the house. If yours won't close, Town staff can turn the valve at the street connection during business hours.
- Check your service line material. The Town keeps a public service line inventory map and reports no lead mains or lead service lines in its system. If your property is marked unknown, the Town asks owners to email a photo of the incoming line to Town Hall.
- Identify the pipe inside. Copper is common in homes from the 1980s; some from that era used plastic systems no longer installed. Note what you see near the water heater.
- Write down the leak history. Locations and dates help the plumber judge whether the system or one section is failing.
- Know who handles permits. Town Hall issues building and zoning permits, and WSSC Water handles plumbing permits and inspections.
Signs and what they usually mean
| Symptom | Likely cause |
|---|---|
| Pinhole leaks in different rooms | Aging copper wearing thin |
| Weak flow throughout the house | Scale or corrosion in old lines, or a partly closed shutoff |
| Leak at a crimp ring on gray plastic pipe | An older plastic supply system reaching the end of its life |
| Rusty water from one section | Leftover galvanized pipe in an older part of the house |
| Pump cycling with taps closed (private well) | A hidden leak somewhere in the system |
Cost factors
- House size, bathrooms and how many floors the lines must reach
- Open or finished basement
- Town water versus a private well and pressure tank
- Reconnecting water treatment equipment
- Material choice and patching
- After-hours help from Town staff at the street valve, if an emergency shutoff is needed outside business hours
Plumbing permits and inspections are handled by WSSC Water, and the work has to be done by a plumber registered with WSSC Water.
