For a Potomac plumbing emergency, shut the main water valve, plus the pump breaker if the house runs on a private well, and get outside if you notice gas. Then call the number on this page to be connected with a local plumber in Potomac.
Potomac grew from farmland into a large-lot suburb around Potomac Village, where Falls Road meets River Road, and its median home dates from 1977. Most homes use WSSC Water for public water and sewer, but Montgomery County gives every property a water and sewer category, and some Potomac parcels are designated for a private well and a private onsite wastewater system that the owner maintains. Which setup you have changes who to call.
What to do now
- Stop the flow. Close the main valve where the supply enters the house. On a private well, turn off the pump's breaker as well.
- Make the area safe. Shut off power or gas to a leaking water heater and stay away from water near outlets.
- Leave if there is a gas odor. From outside, call 911 and Washington Gas at 844-WASHGAS (927-4427), option 1. If a different utility appears on your gas bill, call its emergency line instead.
- Report street problems to WSSC. A break in the road or a sewer manhole overflowing goes to WSSC Water's emergency line, 301-206-4002.
- Hold off on drains if anything is backing up, especially in a home with its own onsite system, where more water only makes it worse.
Signs and what they usually mean
| Symptom | Likely cause |
|---|---|
| No water anywhere, neighbors fine | A closed or failed valve; on a well, the pump, pressure switch or tank |
| Water through a ceiling below a bathroom | A failed supply line, valve or drain connection |
| Every drain slow, lowest fixture backing up | A blocked main drain or lateral, or a full onsite system tank |
| A line spraying after a freeze | A pipe or hose bib that froze and split |
| Irrigation backflow device leaking at spring start-up | A testable assembly damaged over the winter |
Cost factors
Night, weekend and holiday calls generally cost more. Large homes with long pipe runs, finished lower levels and well equipment take longer to diagnose. Gas water heater and gas appliance replacements need a gasfitter holding a WSSC license, and testable irrigation backflow assemblies may only be tested and repaired by WSSC-certified cross-connection technicians, so some jobs call for a specialist. Ask about pricing before work begins.
