What’s in San Diego County’s water?
San Diego County relies on roughly 85% imported, chloramine-treated water. That leaves homes across the county with a persistent chlorine taste and hard-water minerals that scale up fixtures, water heaters, and appliances. A Puragain Water system removes hardness minerals, chlorine, lead, PFAS and more, so the water your family drinks, cooks, and bathes in is clean at every tap.
