Backflow Testing Helps Protect our Drinking Water

In San Diego County backflow preventers are tested yearly to give us all confidence in the protection they offer. If backflow preventers fail, health hazards and pollution could enter our community drinking water. Pacific Backflow has been helping protect Southern California since 1982 through backflow testing, repair, installation, cages and cross connection control services. Our friendly staff is ready to serve you. We Make It Easy!
