Placentia was once known as the "Biggest Little City in Orange County," surrounded by Valencia orange groves. Most of the citrus was replaced by tract homes in the 1950s through 1970s. These homes used galvanized steel supply lines in the earliest tracts, transitioning to copper in the 1960s, with cast iron drain pipes throughout.
After 50 to 70+ years of hard water, these pipe materials are corroded and failing. S&E Plumbing is based in Orange, about 10 minutes from Placentia, and we specialize in the aging plumbing systems found throughout the city.
