Plumbing in Alexandria: what locals should know
Water quality
Alexandria has moderate water hardness — not extreme, but enough to warrant annual water heater flushing. A whole-house filter can improve taste and reduce minor buildup in pipes and fixtures.
Freeze risk
While Alexandria doesn't see extreme cold regularly, freezing temps do occur. Insulate outdoor faucets and any pipes in unheated spaces. Disconnect garden hoses before the first frost.
Material recommendation
PEX piping is the most popular repipe material in Alexandria. It's flexible, quiet, and typically costs 30-40% less than copper. Copper remains a good choice if you prefer the durability and resale appeal.
Local tip
Many Alexandria homes built in the 1970s-80s have polybutylene (gray plastic) water pipes, which are prone to unexpected failures. If your home has them, most plumbers recommend proactive repiping before a catastrophic leak.
