Backflow Testing

Backflow Testing

We conduct thorough annual backflow testing to ensure your water supply remains uncontaminated and compliant with your local water purveyor's requirements.

Maintenance & Repair

Maintenance & Repair

Reliable maintenance and prompt repairs keep your backflow devices functioning smoothly and securely, from worn rubber kits to full assembly replacement.

Cross Connection Surveys

Cross Connection Surveys

Our detailed surveys identify potential cross connections, helping prevent contamination risks before they arise and keeping your site inspection ready.

Backflow Services

Every backflow prevention assembly in California must be tested by a certified tester at least once a year. Our AWWA certified technicians arrive with calibrated gauges, test your device on site, and handle the paperwork so your property stays compliant and your drinking water stays clean.

  • Testing performed on site by AWWA certified technicians
  • Compliance paperwork completed and submitted for you
  • Worn rubber kits and full assembly replacement handled promptly

Cross Connection Control

The X in XConnect stands for Cross Connect. A cross connection is any point where drinking water can meet a non-potable source, and controlling those points is the whole reason backflow assemblies exist. We survey, classify and document them so contamination never gets a path back into the supply.
