Which water system serves my Rockville address, and why does it matter?

Rockville is split between two utilities. The City of Rockville's own 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 an address. The difference carries over to paperwork: for City-water addresses, plumbing permits such as water heater permits come from the City's Department of Community Planning and Development Services, while WSSC-water addresses go through WSSC Permit Services. A plumber who works in Rockville should know to check this before filing.

Is my house old enough to need new pipe?

Rockville's median home was built in 1980, but the range is wide, from postwar subdivisions to recent construction around Town Center. Houses from the 1950s and 1960s may still have galvanized steel, which rusts from the inside and slowly chokes flow. Homes from the 1970s and 1980s were mostly plumbed in copper, which tends to fail as scattered pinhole leaks after decades of use. A single leak doesn't call for a repipe. Several in different rooms, or brown water at more than one tap, usually does.

What about lead in the lines?

The City of Rockville has completed an inventory of service line materials and notified customers, and it says it is responsible for removing lead pipes, while customers share responsibility for lead in home plumbing. In WSSC-served parts of the city, WSSC says it removed all known lead pipe from its distribution system and publishes its own service line map. Neither inventory describes the branch lines inside your walls, which is what a repipe replaces. City water comes from the Potomac River and is disinfected with chlorine.

A Rockville note

Since Rockville is the county seat and a busy I-270 business center, many homes have been renovated more than once. When the plumber visits, point out any remodeled kitchens or baths: those areas may already have newer pipe, and a partial repipe of the untouched sections can be the most sensible plan. Have your water bill handy too, since it shows whether the City or WSSC Water serves the address, and that answer shapes the permit and the schedule.

Repiping questions in Rockville

Who issues the permit for a repipe?

It depends on your water provider. City of Rockville water customers get plumbing permits from the City's Community Planning and Development Services; WSSC Water customers get them from WSSC Permit Services. Check the City's Water Service Provider Map.

Is replacing only part of the plumbing ever enough?

Yes, especially in Rockville houses where a kitchen or bath was already remodeled with new pipe. Replacing only the original sections can cost much less than a whole-house job.

Will new pipe fix weak water pressure?

If the weak pressure comes from rust-narrowed galvanized pipe, new lines usually bring flow back. If the cause is a failing pressure reducing valve, a partly closed main valve or a service line problem, a repipe alone won't fix it.

Does the utility's service line inventory cover the pipes inside my house?

No. The City's service line inventory and WSSC's map cover the line coming into the house. The branch piping inside is the owner's to evaluate.
