Poolesville runs its own sewer system, so a backup there starts with a different phone call than in most of Montgomery County. Hydro jetting clears a clogged building drain or lateral with pressurized water, removing grease, sludge and roots that cabling leaves behind. Call the number on this page to be connected with a local plumber in Poolesville.

Poolesville's own sewer system
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 WSSC Water territory for water and sewer: the Town runs its own collection system and a wastewater treatment plant on Beall Street, which also treats sewage from the nearby Jonesville and Jerusalem areas. The County's water and sewer plan describes the area as served by Town systems and onsite systems, so some properties in and around town are not on municipal sewer. The median home in town was built in 1985.
What to do now
- Stop using water in the house until the line is open.
- Check the lowest drain. Water standing there means the main line is involved.
- If neighbors on the Town sewer are backing up too, call the Town's water and sewer emergency numbers, 240-286-3389 or 240-286-3359. Town Hall is 301-428-8927 during business hours.
- If only your house is affected, the clog is likely in your own building drain or lateral, which is plumber work.
- If the home is not on municipal sewer, say so when you call, since the line ends at a tank.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Basement floor drain fills when upstairs fixtures run | Blockage in the main line below the floor drain |
| Kitchen sink keeps slowing down | Grease built up in the kitchen branch |
| Gurgling toilet when the washer empties | Partial clog forcing air back up |
| Roots on the end of a drain cable | Roots entering through a joint in an older lateral |
| Slow drains house-wide at a home off the Town sewer | Restriction in the line or trouble at the onsite system's tank |
Cost factors
- Access to a cleanout
- Length of the run to the street or to the tank
- Grease versus roots
- Camera inspection
- After-hours timing
Ask the plumber for the camera footage so you have a record of the line's condition. Permits matter only if a repair follows. The Town issues building and zoning permits from Town Hall, while WSSC Water is the inspection agency for plumbing and gasfitting work in Montgomery County.
