What goes wrong in Grass Valley homes
1980s and 90s construction and polybutylene
36% of homes were built between 1980 and 1999. Polybutylene supply pipe was installed widely in US homes from about 1978 to 1995, so houses from these years are worth checking for gray plastic pipe stamped PB2110, usually visible at the water heater or under sinks. Insurers and buyers often ask about it. See polybutylene replacement.
1960s and 70s homes reaching end of life
31% 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.
Propane service
31% 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.
