What goes wrong in Yakima County homes
Pre-1960 homes: galvanized pipe and cast iron
30% of homes in Yakima County's covered ZIP codes were built before 1960, 14% of them before 1940. Houses that old often still have galvanized steel supply lines that rust closed from the inside, and cast iron or clay sewer pipe that cracks and lets roots in. Weak pressure at upstairs fixtures, brown water after a shutoff and slow drains are the usual clues. Typical fixes are whole-house repiping and a sewer camera inspection.
Mostly electric homes
68% 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
58% 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.
