Requirements for Backflow Devices during the Plan Review Process Checklist for Clients – What Device do I Need?
Requirements for Backflow Devices during the Plan Review Process
For a water customer to be considered in compliance, all domestic, irrigation, and fire services to your facility or residence are required to be contained with approved backflow protection. For most residential customers, this approved containment backflow protection is achieved by the installation of a dual check device on the meter yoke. For other services with higher risk, testable backflow assemblies are required to be installed according to Article D: Water Quality Protection and Appendix A: Guidelines and Requirements of the Cross Connection Program.
- Cross-connection control backflow protection is required based on degree of health hazard.
- The backflow assembly shall meet American Society of Sanitary Engineering (ASSE) standards and be on the University of Southern California approval list.
- The plans are reviewed, and notes will be placed on permits to ensure compliance in accordance with the following guidance documents
