In Poolesville, close the indoor shutoff where the water line enters the house to stop a flood, and leave the home before calling anyone if you smell gas. Then call the number on this page to be connected with a local plumber in Poolesville.

Poolesville is a small historic town surrounded by Montgomery County's Agricultural Reserve, and it runs its own utilities. The Town pumps groundwater from its own wells, drilled 285 to 800 feet into the New Oxford Formation aquifer, disinfects it with chlorine, and treats wastewater at its own plant on Beall Street. This isn't WSSC Water territory for water service. Some properties in and around town are on private wells and onsite wastewater systems instead, so check which applies to you.
What to do now
- Close the indoor shutoff. Most Poolesville homes have one where the service line comes in. Turn it clockwise until it stops.
- Call the Town for street-side trouble. For a water main break, a leak at the curb or a sewer backup from the Town line, the Town lists emergency numbers 240-286-3389 and 240-286-3359. Town staff can also shut the valve at the street connection if your indoor valve won't close; a call-out fee applies after 4:00 p.m. and on weekends.
- Leave if there is a gas odor. Washington Gas is the town's gas utility. From outside, call 911 and 844-WASHGAS (844-927-4427), option 1.
- Shut down a leaking water heater at the breaker or gas control.
- Stop using drains if wastewater is coming up, especially on a private onsite system.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Water spraying in a basement or crawlspace | A frozen or corroded pipe that split |
| Wastewater rising in the lowest drain | A blocked house drain or lateral, or a full private system tank |
| No water on a private well | The pump, pressure switch, pressure tank or a tripped breaker |
| Puddle under the water heater | A leaking tank or relief valve |
Cost factors
After-hours and weekend calls generally cost more, and the drive out to western Montgomery County can add to the trip. Well pumps and private systems need different equipment than a clogged drain on Town sewer. For paperwork, the Town Hall issues building and zoning permits, while WSSC Water handles plumbing and gasfitting permits, so a gas water heater replacement still needs a gasfitter holding a WSSC license. The median home was built in 1985, so many original water heaters and valves have already been replaced once. Ask the plumber to explain pricing before work begins.
