Backflow Prevention & Testing in Sun City, AZ

In Sun City’s historic Del Webb neighborhoods, aging infrastructure poses a constant threat to residential water safety. Many homes built between 1960 and 1980 still rely on original galvanized steel supply lines that are now corroding from the inside out. This internal rusting, combined with EPCOR Water’s exceptionally hard supply—averaging 14 to 18 grains per gallon—creates a volatile environment for backflow preventers. High mineral scaling can cause internal check valves to seize, while the notorious local line pressure often spikes between 90 and 110 PSI. These intense conditions frequently lead to mechanical failure in thermal expansion tanks and pressure vacuum breakers near the golf courses. Without professional testing, these failures risk siphoning non-potable irrigation water or pool chemicals back into your home’s drinking water through cross-connections.
