sprinkler irrigation 2Installation of an irrigation system requires compliance with Washington State Law (WAC 245-290) and Edmonds City Code Chapter 7.20.  These Laws require that all irrigation systems have approved backflow protection.  An City permit is also required when installing an irrigation system.

Without proper backflow protection, your irrigation system could endanger the health of your family, neighbors, and others in the community who are using the public water system.

The following state approved backflow assemblies are required to be installed per City of Edmonds standards, and must be tested by a Washington State Certified Backflow Assembly Tester upon installation, repairs, relocation, and annual thereafter:

arrow-b  Atmospheric Vacuum Breaker (AVB)
arrow-b  Pressure Vacuum Breaker Assemblies (PVBA)
arrow-b  Double Check Valve Assemblies (DCVA)
arrow-b  Reduced Pressure Backflow Assemblies (RPBA)

Improper installations of a State Approved Backflow Prevention Assembly or failure to have the backflow prevention assembly tested are grounds for termination of water service.  Please note, an AVB does not required annual testing.
