In Clarksburg, stop an indoor flood by closing the main valve, usually in the basement or utility room where the water line enters, and leave the house at once if you smell gas. Then call the number on this page to be connected with a local plumber in Clarksburg.

Clarksburg is among the youngest communities in the region. The median home was built in 2010, and roughly 84 percent of homes went up between 2000 and 2019. That means fewer worn-out pipes and more first-time failures: original water heaters reaching the end of their life, supply hoses on washers and toilets, and fixtures installed with the house. WSSC Water provides public water and sewer across most of the area, while some properties on the rural edges are categorized for private wells and onsite wastewater systems, so service varies by address.
Steps to take first
- Turn the main shutoff clockwise until it stops, then open a faucet on the lowest floor.
- Cut the power or gas to a water heater that is leaking.
- For a gas odor, walk out without using switches, then call 911 and Washington Gas at 844-WASHGAS (844-927-4427), option 1, from outside.
- If water is coming up at the curb or in the street, call WSSC Water's Emergency Service Center at 301-206-4002. WSSC is responsible for the service line from the main to the property line; from the property line into the house, the line belongs to the owner.
- If a residential fire sprinkler line is leaking, call right away and don't try to disable the system yourself.
Symptom and likely cause
| Symptom | Likely cause |
|---|---|
| Water heater pan full or tank dripping | An original tank reaching the end of its life |
| Water under the washer or behind a toilet | A burst supply hose or failed stop valve |
| Leak near the sprinkler riser | A fitting or the backflow assembly on the fire sprinkler line |
| Basement drain backing up | A blockage in the house drain or lateral |
| Hose bib spraying inside the wall after a freeze | A frost-free faucet with a hose left attached |
Cost factors
When you call drives much of the price, and night, weekend and holiday rates are usually higher. Newer homes are often easier to work in, but finished basements and cramped mechanical closets in townhouses can slow access. WSSC notes that homes built from 2007 to 2009 had testable double-check assemblies on their fire sprinkler systems, and work on those must be done by a WSSC-certified cross-connection technician. Gas water heater replacements need a gasfitter holding a WSSC license and a WSSC permit. Get the pricing explained before the work starts.
