Leak Detection in Takoma Park, MD

What makes a leak in an older Takoma Park house hard to find?

Takoma Park began in 1883 as a Victorian commuter suburb on the District line, and its National Register historic district still holds many of those early homes. Plaster walls, layered flooring and decades of renovations mean pipes often run in places that aren't obvious. Galvanized steel supply lines corrode from the inside and can leak at threaded joints; old copper may have pinholes; and original gate valves often won't close completely, which makes isolating sections during a test slower.

How do I check for a leak before calling?

With everything turned off, look at the WSSC Water meter. If it moves, water is escaping. Close the main valve and look again: if the meter stops, the leak is inside; if it keeps going, the buried line outside is the likely source. Check toilets with a few drops of food coloring in the tank. In the basement, look along ceiling joists below bathrooms and at the base of the water heater. Report water coming up in the street or near the meter to WSSC at 301-206-4002.

What about the service line itself?

WSSC Water says each service line has a utility-owned portion and a customer-owned portion. Its What's Your Pipe Type? program inventories materials on both sides, follows up on lines listed as lead, galvanized or unknown, and helps owners replace lead lines on either portion. In a house this age, it's worth looking up your address before paying for repairs on a buried line that may need to be replaced anyway.

WSSC water is disinfected with chlorine, and its tap analysis lists average hardness of about 140 mg/L for Potomac plant water and 64 mg/L for Patuxent plant water. Most plumbing repairs in Montgomery County need a plumber who holds a WSSC Water license, working under a WSSC permit.

One local note

Takoma Park's heavy tree canopy is part of its charm, but mature roots and decades of settling can stress buried lines. If a soggy patch appears in the front yard between the meter and the house, a plumber can use acoustic equipment to locate the break before any digging.
