Repiping in District Heights, MD

District Heights homes

District Heights is a small, fully built-out city near MD Route 4 that began as farmland and was incorporated in 1936. Many of its Cape Cod-style homes date to the 1940s, when developers built single-family houses with FHA financing. Supply pipe from that period is often galvanized steel, which rusts from the inside and gradually restricts flow; later repairs may have added copper sections. Homes built in the 1950s and 1960s usually have copper, which can pinhole with age.

Cape Cods are compact, which helps. Many have a basement or crawlspace below and a bathroom or two above, so new lines can often be run with relatively few openings. Upstairs bedrooms tucked under the roof slope can be harder, since pipe may need to pass through knee walls near the cold exterior. The plumber should keep new runs out of those cold spaces where possible.

WSSC Water supplies the city and owns the service line from the main to the property line. The homeowner owns the section from the property line into the house. WSSC's What's Your Pipe Type? program identifies service line material, and some customer-side galvanized lines require replacement.

Plumbing permits and inspections come from WSSC Water, not DPIE, and WSSC requires a plumber holding its license for interior re-piping. District Heights is a municipality, so building permit responsibility can differ from unincorporated areas; the plumber should confirm what the job needs.

Repair or repipe

Signs

• Brown water when taps first open
• Low pressure at more than one fixture
• Leaks at threaded joints or new pinholes in copper
• Corroded shutoff valves

Timing

Galvanized pipe tends to fail slowly, so there is usually time to plan. Still, old pipe near exterior walls or in an unheated crawlspace is most likely to split in a hard freeze. If you see signs of trouble in fall, it is worth scheduling before winter.
