Glenn Dale homes get water from WSSC Water, which owns the service line from the main to the property line; past that point, including pipe under a slab or basement floor, the owner is responsible. A leak in that buried section is a slab leak and calls for a plumber. Call the number on this page to be connected with a local plumber in Glenn Dale.
Can a fairly new Glenn Dale house have a slab leak?
It can. The median home in Glenn Dale dates to about 1991, newer than most of the inner county, and many houses here have copper or plastic supply lines. That lowers the odds of corrosion but does not remove the other causes. A line that was nicked when concrete was poured, a fitting buried under the slab, or pipe that rubs against stone as the house settles can all start leaking years later. Basement and lower-level floors count: if the water service rises through the concrete, or a branch runs under it to a bath or bar sink, it is in the same position as pipe under a slab-on-grade house.
Is the leak under the house or in the yard?
A simple test helps. Close the main shutoff inside the house and watch the WSSC meter. If the meter keeps moving, the leak is on the line between the meter and the house, which sits on your side of the property line. If the meter stops, the leak is inside, and under the floor is a possibility. Water surfacing near the street or meter box is worth reporting to WSSC's emergency line, 301-206-4002, because that may be the utility's portion.
How does a plumber find it without tearing up the floor?
The usual sequence starts with a pressure test to confirm a leak and separate hot from cold. Then the plumber listens through the concrete with acoustic equipment and scans for heat with a thermal camera, which works well on hot lines. Some jobs use tracer gas on a stubborn cold-side leak. The goal is a precise mark so only a small square of floor is opened, or so you can decide to reroute and avoid the concrete entirely. WSSC Water requires a plumber holding its license for interior re-piping and service line repairs, and it permits and inspects that work.
A local note
Glenn Dale is unincorporated, so building permits come from Prince George's County DPIE in Largo, while plumbing permits and inspections go through WSSC Water. If a repair touches finished walls or flooring, your plumber can tell you which pieces need permits.
