Emergency Plumber in Derwood, MD

Derwood sits just north of Rockville, between Shady Grove Road and Lake Needwood, and it is largely a 1980s community: about two-thirds of its homes were built in that decade, the median build year is 1985, and only about 15 percent predate 1980. In neighborhoods like Mill Creek Towne and Needwood Estates, that puts many houses on their second or third water heater, with original shutoff valves and washer or toilet supply hoses that have never been changed. WSSC Water provides water and sewer service, and most WSSC sewage from this part of the county is treated at the Blue Plains plant.

Steps to take now

1. Find the main valve, typically in the basement or utility room on the front wall, and turn it clockwise until it stops.
2. Open the lowest faucet in the house to drain the pressure.
3. Turn off the breaker or gas control on a water heater that is leaking.
4. If you smell gas, leave, then call 911 and Washington Gas at 844-WASHGAS (844-927-4427), option 1.
5. For water surfacing at the curb, call WSSC at 301-206-4002. WSSC owns the service line from the main to the property line; from there into the house it belongs to the owner.

Symptoms and what they point to

Cost factors

Price depends heavily on timing, since nights, weekends and holidays usually cost more. A leak behind a finished wall takes longer than one in an open utility room, and replacing a water heater or a section of service line is a bigger job than swapping a hose. Gas water heater replacements need a gasfitter holding a WSSC license and a WSSC permit, and irrigation backflow repairs need a WSSC-certified cross-connection technician. Ask about pricing first.
