A plumbing inspection in Poolesville covers the water heater, supply and drain piping, fixtures, shutoffs and gas connections, and on properties outside the Town system, the well equipment. Poolesville runs its own groundwater supply and sewer plant rather than WSSC, and some nearby properties use private wells and onsite systems. Call the number on this page to be connected with a local plumber in Poolesville.

Poolesville is a small historic town in western Montgomery County surrounded by the County's Agricultural Reserve. It isn't on WSSC water. The Town draws its supply from wells drilled 285 to 800 feet into the New Oxford Formation aquifer, disinfects it with chlorine, and treats sewage at its own plant on Beall Street. Some properties in and around town are on private wells or onsite systems instead. The median home was built around 1985.
What to do now
- Confirm whether the house is on Town water and sewer or a private well and onsite system.
- Look the address up on the Town's service line inventory map; if it's listed as unknown, the Town accepts a photo of the incoming line.
- Find the indoor shutoff where the service line enters; most homes have one.
- Ask the seller for the water heater's age and any well or pump records.
- Write down drips, slow drains or pressure changes you notice.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Short bursts of pressure, then a drop | Well pressure tank losing its air charge, on private wells |
| Sediment or grit in aerators | Debris from the supply or an aging water heater |
| Indoor shutoff won't close fully | Old valve worn or seized |
| Slow drains throughout the house | Blockage in the building drain |
| Water heater relief valve weeping | High pressure or thermal expansion |
The Town's water quality report states its system has no lead mains or lead service lines. For a main break, leak or sewer backup on the Town's side, it lists emergency numbers 240-286-3389 and 240-286-3359, and Town staff can shut the valve at the street connection, with a call-out fee after hours.
Cost factors
- House size and number of baths
- Well equipment to check, if the property has its own
- Adding a camera run of the building drain
- Gas appliances or outbuildings with water lines
- Exposed piping in crawlspaces or garages that needs a freeze check
Town Hall issues building and zoning permits, and WSSC Water handles plumbing and gasfitting permits. Washington Gas is the town's gas utility; if you smell gas, leave the house, then call 911 and Washington Gas at 844-WASHGAS (844-927-4427), selecting option 1.
