Columbia was built as a planned community starting in 1967, so most homes are from the late 1960s onward. The most common calls are ageing water heaters, original fixtures and supply lines, and in some homes built from the late 1970s to mid-1990s, gray polybutylene pipe that's worth replacing. Water and sewer come from Howard County.
Plumbing in Columbia: what's different
The older villages — Wilde Lake, Harper's Choice, Oakland Mills and Long Reach — are now 40 to 55 years old, which is when original plumbing tends to fail: corroded shut-off valves, failing water heaters and worn fixtures. Newer villages such as Kings Contrivance and River Hill are more likely to need water heater replacements than repiping.
Many Columbia homes are townhouses, where a leak can affect a neighbor's wall. Shutting off your own main quickly matters; it's usually in the utility closet near the water heater.
