What goes wrong in Benton County homes
Mostly electric homes
79% 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
45% 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.
