What goes wrong in Williamson County homes
Newer homes on their first water heater
65% of homes here were built in 2000 or later. Those houses usually have PEX or CPVC supply lines in good shape, so the work is on equipment: original tank water heaters past their 8 to 12 year service life, expansion tanks, pressure regulators and fixtures. See water heater replacement.
Hard water
Texas water is generally hard. With 50% of homes here on electric heat, scale on electric water heater elements is a frequent failure, and newer homes with tankless heaters need yearly descaling. See water softener installation.
