Waxhaw's housing is among the newest in the region: Census data puts the median home at 2010, with about 81% built since 2000 and 83% owner-occupied. Larger homes on bigger lots mean more fixtures, often two water heaters or a tankless unit, irrigation systems with backflow assemblies, and longer service lines between the meter and the house. Outlying properties may be on private wells and septic.
Waxhaw also handles its own building permits, separately from Union County, which is worth knowing before any water heater or repiping job.
Common plumbing problems in Waxhaw homes
Why does my tankless water heater go cold in the middle of a shower?
Scale buildup on the heat exchanger, a flow rate too low to keep the burner on, or a clogged inlet filter are the usual causes. Tankless units need regular descaling, and skipping it leads to error codes and temperature swings that are usually fixed with service rather than replacement.
Where is the leak if my yard is wet but the meter is far from the house?
On large lots, a leak on the service line between the meter and the house can surface well away from either end. Electronic leak location finds the spot so only a small section has to be dug up. See water line repair and leak detection.
Does my irrigation backflow assembly need attention?
Backflow assemblies need periodic testing, and assemblies above ground should be drained or insulated before hard freezes so they don't crack. See backflow testing.

Wells, water and who to call
Water service in and around Waxhaw depends on the address, so check your bill for your provider before reporting a problem. Leaks inside the house or between the meter and the house are a plumber's job. For homes on private wells, Union County Environmental Health permits wells and offers bacterial and inorganic water testing for a fee; test after any change in taste, smell or color.
