Burst Pipe Repair in Rockville, MD

Which water system serves my Rockville home?

Rockville is split between two providers. The City of Rockville's own water system serves about 70 percent of the city, and WSSC Water serves the rest. The City publishes a Water Service Provider Map so you can check your address. For a water main break or sewer backup on City water, Rockville lists a 24-hour emergency line, 240-314-8567. On WSSC water, call WSSC's emergency service center at 301-206-4002. Either way, pipes inside the house are fixed by a plumber you hire.

Who issues the permit for the repair?

That also follows the water provider. The City's water heater permit guide says addresses on City water apply to Rockville's Department of Community Planning and Development Services (CPDS), while addresses on WSSC water go through WSSC Water Permit Services. A plumber can confirm whether a small fix needs one; a repair that turns into a water heater swap or service line work is more likely to. A plumber who works in Rockville will know which office applies once you confirm your provider.

Why do pipes burst in Rockville houses?

Rockville's median home was built in 1980, so the city mixes postwar subdivisions like Twinbrook with newer construction. Older homes may still have original valves and supply lines, and those parts wear. The most common cause, though, is cold: pipes in exterior walls, unheated garages, crawlspaces and outdoor faucets freeze during a hard cold snap, the ice expands and the pipe splits. The leak often shows only when things thaw. Water pressure spikes and corroded fittings account for many of the rest.

A burst usually announces itself with water coming through a ceiling, spreading across a basement floor or running down an outside wall. A sudden pressure drop at every tap is another clue.

A Rockville note on water quality

City water comes from the Potomac River and is treated with chlorine. Rockville says it has completed a service line material inventory and notified customers, and that it is responsible for removing lead pipe, while customers share responsibility for lead in home plumbing. If a burst pipe leads to replacing older pipe, ask the plumber what material is in the walls and on the line coming into the house.
