Poolesville runs its own water system from town wells rather than WSSC Water, and its median home dates to 1985, so most showers have single-handle cartridge valves that wear in the usual ways. A drip, a sticky handle or erratic temperature generally means new internal parts. Call the number on this page to be connected with a local plumber in Poolesville.
Poolesville's water and your shower
The Town of Poolesville supplies water from its own wells, drilled 285 to 800 feet into the New Oxford Formation aquifer, and the groundwater needs only minimal treatment before chlorine is added. Some properties in and around town use private wells instead. Groundwater can carry minerals that build up inside a valve, so a cartridge that sticks or loses flow after years of use is no surprise. The Town's annual water quality report is the place to check what's in the water at your tap.
What to do now
- Use the indoor shutoff. Most Poolesville homes have a shutoff valve where the service line enters the house. Close it if the shower won't stop running.
- Call the Town if that valve fails. Town staff will turn the valve at the street connection during business hours; after 4 p.m. or on weekends there's a call-out fee.
- On a private well, switch off the pump at its breaker to stop the system from repressurizing.
- Check below the bathroom for drips or staining.
- Write down the symptom and brand so the plumber can bring the right cartridge.
Signs and likely causes
| Symptom | Likely cause |
|---|---|
| Drip after shutoff | Worn cartridge or seals |
| Flow drops at one shower only | Mineral or sediment buildup in the cartridge or inlet screens |
| Hot surges when a toilet flushes | Pressure-balancing spool sticking |
| Handle stiff or gritty | Scale on the cartridge stem |
| Spout and head both running | Worn diverter |
Cost factors
Price depends on whether a cartridge fixes the problem or the valve body has to come out, how easy the valve is to reach, and whether parts for your brand are on the shelf. On a private well, a plumber may also suggest a sediment filter if cartridges keep clogging. For paperwork, Poolesville's Town Hall issues building and zoning permits, while WSSC Water is the inspection agency for plumbing and gasfitting work in Montgomery County; ask which applies before a valve body replacement or a remodel. Homes outside town limits that aren't on the Town system may also be on a private onsite wastewater system, which doesn't change the valve repair itself.
