What This Means for Your Plumbing
South Gate's very hard water (160-210 PPM) causes aggressive mineral deposits in water heaters, reducing efficiency and shortening lifespan. The city's older housing stock from the 1940s-1960s is particularly vulnerable to hard water damage in original plumbing systems.
