Longview homes and their plumbing

With that many older homes, original galvanized supply pipe and cast iron or clay drains are still common, so leaks, rust and root intrusion come up often.

What goes wrong in Longview homes
Pre-1960 homes: galvanized pipe and cast iron
38% of homes in Longview's covered ZIP codes were built before 1960, 16% 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
90% 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.
1960s and 70s homes reaching end of life
32% of the housing here dates from 1960 to 1979. Original copper supply lines in those homes are now 45 to 65 years old, and cast iron drains of that age scale up inside and crack. Seized shutoff valves, pinhole leaks and recurring main-line clogs are common calls. A camera inspection shows the condition of the sewer line before anyone digs.
Winter freezes
70% 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.
