Cornelius wraps around the southeast shore of Lake Norman. Census data puts the median home at 2002, with about 56% built since 2000 and only 4% before 1960. Lake homes tend to be large, with more bathrooms, longer pipe runs, two water heaters and irrigation, and some neighborhoods from the late 1980s and early 1990s may still have polybutylene supply pipe.
Common plumbing problems in Cornelius
Irrigated lawns are common, and backflow assemblies need periodic testing and freeze protection. See backflow testing in Cornelius.
One of my two water heaters failed. Should I replace both?
Lake homes built with two tank heaters usually had both installed the same day. When one fails, check the other's age and condition; if it's close behind, replacing both on one visit can save a second trip. See water heater installation in Cornelius.
Why does hot water take so long to reach the far bathroom?
In large floor plans, the far bathroom can be a long run of pipe from the heater. A recirculation pump or a point-of-use heater fixes the wait without replacing the main heater.
Could my home have polybutylene pipe?
Homes built or replumbed between the late 1970s and mid-1990s might. It's flexible gray plastic supply pipe, often stamped PB2110, and tends to fail at fittings without warning.
