Expert Plumbing Services in Washington, District of Columbia

Many houses built before the 1980s still get their water through a lead service line running from the street main to the house. The city's Lead Free DC program has been replacing the public side, but the private side is the homeowner's responsibility. A lead line can usually be spotted where the pipe enters the basement. Lead is dull gray, soft enough to scratch with a coin, and often has a swollen, bulb-like connection. Replacing it with copper or approved plastic is a one-day dig for most rowhouses and permanently removes the concern.

With hardness near 7 grains per gallon, Washington water leaves mineral scale everywhere it sits and heats. Showerheads crust over, faucet aerators clog, and dishwashers and washing machines work harder than they should. The worst damage happens inside water heaters, where sediment piles up on the burner or elements, wastes energy, and shortens the tank's life. Annual flushing and periodic anode rod checks keep a heater running close to its full lifespan. A softener or whole-house filter is worth discussing if scale keeps coming back.

January nights average near 30 degrees, and every few winters a deep freeze settles in for days. Pipes in exterior walls, unheated attics, crawl spaces, and outdoor hose bibs are the first to freeze and the first to burst when they thaw. Rowhouses with additions are especially vulnerable where new plumbing runs through cold corners. Insulating exposed pipe, sealing drafts, and shutting off and draining hose bibs before winter prevent most freeze damage. If a faucet stops flowing during a cold snap, leave it open a crack and call before the pipe splits.

A century of use wears on pipe from both sides. Galvanized supply lines rust inward until water pressure drops to a trickle, and cast-iron drain stacks corrode and scale until they clog or leak. Brown-tinted water, slow drains on every floor, and recurring clogs in the same line are classic signs. Spot repairs make sense when one section fails. But when the whole system is at the end, a planned repipe costs less and disrupts less than a string of emergency fixes.

Older neighborhoods with mature street trees, like Cleveland Park and Chevy Chase, still have clay tile sewer laterals with joints that roots love. A small root hair finds a joint, grows into a mat, and eventually closes the pipe. Slow drains across the whole house, gurgling toilets, and sewage smells in the basement point to the lateral, not the fixtures. A camera inspection shows exactly where the roots are, and trenchless repair can replace the line without tearing up the front yard.

Parts of the city sit on an older combined sewer system, so a hard summer downpour can push water back toward basements faster than it drains away. Add a tired sump pump or a floor drain full of silt and a storm turns into a cleanup job. The fix is usually layered. You want a working sump pump with a battery backup, a backwater valve where it fits, clear gutters and downspouts, and grading that moves water away from the foundation. We check the whole chain, not just the pump.
