Why Alexandria homes need these repairs

Alexandria is an independent city across the Potomac from Washington, with 18th- and 19th-century row houses in Old Town and mid-century garden apartments and single-family homes to the west. Its water comes from Potomac River and Occoquan Reservoir plants, and very old housing and cold winters drive pipe, sewer and frozen-line calls.

Pipe problems in Alexandria's 1970s homes

The median home in Alexandria was built in 1977, and 55% of homes predate 1980. Homes from that era were typically built with copper supply, early plastic (ABS or PVC) drains, some cast iron, which is where leaks, low pressure and drain problems usually start as they age.

  • Galvanized steel supply (1900–1960)
  • Copper supply (1950–2000)
  • Polybutylene (some homes) (1978–1996)

Alexandria's water supply and your plumbing

Alexandria's drinking water is treated by Fairfax Water at the Corbalis plant on the Potomac River and the Griffith plant at the Occoquan Reservoir, then distributed by Virginia American Water, a private company. [1]

The water is treated with corrosion inhibitors before Virginia American Water distributes it to Alexandria customers. [2]

Alexandria plumbing questions

Should old pipes in a Alexandria home be repaired or replaced?

One leak in otherwise sound pipe is usually repaired; when galvanized or failing pipe leaks in several places, repiping costs less over time. Why it comes up in Alexandria: Historic row houses still carry galvanized and old copper lines.

Can recurring clogs in Alexandria mean a sewer line problem?

Yes. When several drains back up together, the main sewer line is the likely cause, and a camera inspection shows whether it's roots, a sag or a break. Why it comes up in Alexandria: Very old laterals in Old Town and Del Ray crack and take in roots.

Who provides water service in Alexandria, Virginia?

Virginia American Water, a private company, distributes water that Fairfax Water treats from the Potomac River and Occoquan Reservoir.

Can I replace plumbing in an Old Town historic house without special approval?

Old Town is a historic district, and exterior changes there can need review. Ask the city's Planning & Zoning department before moving vents, meters or exterior lines; interior work still needs normal plumbing permits.

Does Alexandria water contain lead?

The treated water doesn't, but old lead service lines or solder in a house can add it. Corrosion inhibitors reduce the risk; testing your tap gives a clear answer.

Why do Del Ray sewer lines back up?

Many date to the early 1900s and are clay or cast iron that cracks and lets roots in. A camera inspection shows whether lining or replacement is needed.
