What goes wrong in Oroville homes

1960s and 70s homes reaching end of life

33% 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.

Pre-1960 homes: galvanized pipe and cast iron

27% of homes in Oroville's covered ZIP codes were built before 1960. 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.

Propane service

15% of homes here use bottled or tank propane for heat, typical of areas beyond the gas mains. Propane water heaters, ranges and generators need correctly sized lines and fittings rated for LP. See gas appliance hookups.
