Poolesville runs its own water system, so a slab leak here is handled a little differently than in WSSC areas: the Town looks after its mains, and the plumbing inside your home, including lines under a basement or slab floor, is yours to repair. Some homes around town use private wells instead. Call the number on this page to be connected with a local plumber in Poolesville.
Poolesville basics
Poolesville is a small historic town in western Montgomery County, surrounded by the County's Agricultural Reserve. Unlike most of the county, it is not on WSSC Water. The Town draws groundwater from its own wells, drilled 285 to 800 feet into the New Oxford Formation aquifer, disinfects it with chlorine and runs its own wastewater treatment plant. Some properties in and around town are on private wells and onsite systems instead. The median home was built around 1985, so many houses are near 40 years old, an age when buried copper and fittings start to fail.
What to do now
- Confirm the leak. Turn off every fixture and watch the water meter, or on a private well, listen for the pump running with nothing open.
- Use the indoor shutoff. The Town notes that most homes have an indoor valve where the service line enters. Close it if water is spreading.
- Call the Town for street-side trouble. For a main break or a leak near the street connection, the Town lists emergency numbers 240-286-3389 and 240-286-3359. Town staff can close the valve at the street connection during business hours, with an added charge after hours.
- Protect the lower level. Move rugs, boxes and electronics off a wet floor.
- Note what you've seen so the plumber knows where to start.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Meter or private well pump active with all taps closed | Pressurized leak somewhere in the supply piping |
| Floor warm along a line from the water heater | Hot water branch leaking under the slab |
| Damp corner of a finished basement in dry weather | Supply line seeping through the floor |
| Wet ground between the house and the street | Service line leak, on the Town's or the owner's side |
| Water heater running more than normal | Hot water being lost under the floor |
Cost factors
Price depends on how quickly the leak is pinpointed, whether the slab is opened or the line rerouted, and the flooring and drying work involved. Building and zoning permits come from Town Hall, while plumbing permits are handled by WSSC Water Permit Services. Since the Town reports no lead mains or lead service lines in its system, a Poolesville repair is usually about wear and age rather than lead replacement.
