RPZ & PVB TESTING & BACKFLOW PREVENTERS

The states and cities require RPZ's to be tested annually and rebuilt every five years. Backflow preventers stop the flow of chemicals contaminated or polluted water back into the domestic water system. Without these devices our water supply systems could be contaminated possibly causing diseases, physical and mental effects and even death. These devices require annual testing by certified personnel to ensure these devices are working properly. These devices are also required to be rebuilt every five years to make sure the devices will continue to protect our water supply.
