When the buried pipe carrying WSSC Water into a Germantown house starts leaking, the clues are usually a patch of lawn that never dries, pressure that sags at every tap or a bill that jumps. A plumber can confirm the leak, expose the damaged section and repair or replace it under a WSSC permit. Call the number on this page to be connected with a local plumber in Germantown.

What happens when you call
Your call goes to an independent plumber who covers Germantown and the rest of the upper I-270 corridor. Expect a short set of questions: where the ground is wet, how long it has been that way, whether pressure dropped suddenly or gradually, and whether the meter keeps turning with every fixture off. Those answers separate a buried service line problem from a leak inside the house, which changes the tools and the crew the plumber brings.
On site, the plumber usually starts at the meter, then traces the route of the line toward the foundation with listening equipment or a tracer so the excavation stays as small as possible. Once the break is exposed, you get options: a repair coupling on one bad spot, or a new run of pipe from the meter connection to the house.
What drives the price
- Depth and length. A long front setback means more digging and more pipe.
- Spot fix or full replacement. Swapping one failed fitting is far less work than a new line.
- What is on top. Driveways, walkways, retaining walls and mature plantings add restoration time.
- Where the line enters the house. A wall sleeve behind a finished basement takes more care than an open utility room.
- Permitting. WSSC Water issues the plumbing permit and inspects the work.
Germantown conditions
Germantown grew quickly after a sewer line reached the area in 1974, and in ZIP 20874 the single largest group of homes was built in the 1980s, with fewer than one in five predating 1980. Many service lines here are therefore original to houses that are now around 40 years old. At that age the usual failures are a compression fitting at the meter connection, a joint near the foundation wall, or pipe nicked during a deck, fence or landscaping project after the house was built.
WSSC Water supplies the area and handles plumbing permits and inspections in Montgomery County. Most plumbing work, including water service line repairs, is reserved for a plumber registered with WSSC Water, so this is not a project for a weekend shovel. WSSC also publishes a service line inventory map that lists pipe materials, including the private portion, if you want to know what your line is made of before deciding on repair or replacement.
Before the plumber gets there
- Find the main shutoff where the line enters the basement or utility room and make sure it turns
- Take a meter reading, use no water for an hour, then read it again
- Mark any soft or wet ground with a stake so it is easy to show
- Move cars off the driveway if the line runs under it
- If water is rising in the street or at the meter, call WSSC Water at 301-206-4002
