Poolesville runs its own water system, pumping groundwater from Town wells and adding chlorine, so it is not on WSSC Water. Some properties in and around town use private wells and onsite systems instead. Either way, a softener decision here starts with a test of the water coming into your house. Call the number on this page to be connected with a local plumber in Poolesville.
Poolesville's groundwater
The Town of Poolesville draws from wells 285 to 800 feet deep in the New Oxford Formation aquifer, treats the water minimally and disinfects it with chlorine. It also runs its own wastewater treatment plant on Beall Street. The Town's water quality report lists no lead mains or lead service lines in the system. Montgomery County's water and sewer plan describes the area as served by Town and onsite systems, so some homes nearby have their own wells and private onsite wastewater systems. With groundwater, hardness isn't something to guess at; a tap test, or a lab test for a private well, gives you the number. The median home in town was built in 1985.
What to do now
- Confirm your supply: a Town water bill or a private well.
- Test hardness at the tap; for a private well, use a lab panel that also covers iron, manganese, pH and bacteria.
- Find where regeneration water would drain. Homes on a private onsite system need a plan for the brine.
- Check the water heater for rumbling or sediment, an early sign of scale.
- Call with your results.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| White scale on fixtures and kettles | Calcium and magnesium in the groundwater |
| Rust-colored stains in toilets and tubs | Iron, more common on private wells |
| Softener uses salt but water stays hard | Exhausted resin or a setting below actual hardness |
| Brine tank overflowing | Stuck float or a blocked drain line |
| Pressure drop after install | Undersized unit or a clogged sediment prefilter |
Cost factors
- Town water versus a private well needing extra treatment
- Drain planning for homes off the Town sewer
- Equipment size and single- or dual-tank design
- Plumbing permits through WSSC Water Permit Services; the Town Hall issues building and zoning permits
- Removing old treatment equipment
For a water main break, leak or sewer backup on the Town system, Poolesville lists emergency numbers 240-286-3389 and 240-286-3359, and Town staff can shut the valve at the street connection. That's useful to know if a softener connection fails and you can't stop the water at the house. Inside, a clearly marked bypass valve lets you isolate the softener without shutting off the whole home.
