Backflow Testing & Repair in Phoenix, AZ

Protecting Phoenix's Water Supply

Backflow prevention is one of the most important — and most overlooked — parts of your irrigation system. A backflow preventer stops contaminated water from your irrigation lines from flowing backward into the clean municipal water supply. Without a properly functioning device, fertilizers, pesticides, and soil bacteria from your yard could contaminate your family's drinking water and your neighbors'. Arizona takes this seriously, and Maricopa County requires annual testing of all backflow prevention devices connected to the public water system.

Annual Testing Requirements in Arizona

If your Phoenix-area property has an irrigation system connected to city water, you're required to have your backflow prevention device tested annually by a certified tester. The city sends notices, and failure to comply can result in fines or even water service disconnection. Testing must be performed by a technician certified through the Arizona Department of Environmental Quality. Our team carries full certification and can test, repair, and file the required compliance documentation with your water provider — taking the hassle completely off your plate.

What Happens During a Backflow Test

During a backflow test, we attach specialized gauges to the test ports on your backflow device and measure the pressure differentials across each check valve and relief valve. The test verifies that the device will prevent reverse flow under all conditions. A properly functioning backflow preventer will pass on the spot, and we file the certification paperwork with your water provider the same day. If the device fails the test — which happens when seals wear out, springs weaken, or debris lodges in the check valves — we diagnose the specific failure, provide a repair quote, and in most cases can rebuild the device on the spot to bring it back into compliance.

Repair & Replacement Services

Over time, backflow devices wear out. The rubber seals dry and crack in Phoenix's heat, springs lose tension, and mineral deposits from hard water degrade internal components. We carry repair kits for all major backflow device brands including Watts, Wilkins, Febco, and Apollo. A standard rebuild takes about an hour and is significantly less expensive than full device replacement. However, if your device is severely corroded or damaged beyond repair, we install new code-compliant devices and handle all the associated permitting and inspection requirements. We also relocate backflow devices that are improperly positioned or blocking access.
