What goes wrong in Franklin County homes
Newer homes on their first water heater
47% 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.
Mostly electric homes
67% of occupied homes here heat with electricity, and electric tank water heaters are the norm. Failed elements and thermostats are repairable, but tanks that leak need replacement. Heat pump water heaters are an efficient replacement where there's space and airflow.
Winter freezes
38% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a cold Washington winter those are the lines that freeze and split. See frozen and burst pipe repair.
