Silicon Valley's boom-bust development cycles have left many San Jose homes with layered plumbing systems — original copper supply lines from the 1960s mixed with PEX additions from a 1990s renovation and CPVC patches from a 2010 repair.

San Jose has a split infrastructure profile: established neighborhoods retain copper supply lines dominant, cast iron drain stacks in older homes from the 1950s–1970s in Willow Glen and Rose Garden, 1980s–2000s in newer tracts, while newer developments use current-standard materials — and that mix, combined with alluvial valley fill — relatively stable but saturated during wet winters and the undefined, means plumbing conditions and common failure modes vary significantly by address across the city.
