San Jose homeowners deal with a plumbing challenge most people don’t think about until something breaks: hard water. San Jose Water Company’s supply — a blend of Sierra Nevada snowmelt via the Hetch Hetchy system and groundwater from the Santa Clara Valley aquifer — tests at 10–14 grains per gallon of calcium and magnesium hardness. That’s classified as very hard water, and it’s one of the highest readings of any major California city. Inside your pipes, that mineral content gradually builds up as scale — narrowing supply lines, wearing out faucet cartridges, coating the inside of your water heater tank, and shortening the life of every water-using appliance in your home. In older San Jose neighborhoods like Rose Garden (95126), Willow Glen (95125), Naglee Park (95112), and Cambrian Park (95008), where many homes still have their original copper or galvanized steel supply lines from the 1950s through the 1970s, the combination of aging pipe material and decades of hard water exposure makes proactive plumbing maintenance especially important. If your home was built before 1970 and has never been repiped, there’s a reasonable chance you have galvanized steel pipes that are at or past the end of their functional lifespan.
