What to check for San Diego

  • Due basis: San Diego says all backflow devices are tested annually and points customers to the approved tester list when the Public Utilities Department contacts them for compliance.
  • Who is affected: Multi-family, commercial, industrial, dedicated irrigation, and fire-protection services that the Public Utilities Department identifies as requiring backflow protection.
  • Program phone: 858-292-6329
