Backflow PreventionWhat is backflow and why do I need to prevent it?
Backflow Prevention and Municipal Regulations
The majority of sprinkler irrigation systems in B.C. are connected to a potable (safe for drinking) water supply. This potable water supply could consist of a city water main, a well, or any other source of drinking water supplied by your local water purveyor. The connection of a sprinkler irrigation system, with its maze of pipes, valves, and sprinkler heads to a potable water supply, is called a cross connection.
Herbicides, pesticides, fertilizers or animal feces may collect in cesspools of water around the sprinkler heads, creating a potential for the contaminants to be drawn back through the sprinkler irrigation system. This flow of contaminates (by means of Backflow or Backsiphonage) into the potable water supply line, without an approved means of cross connection control, will result in contamination of potable water supply.

Why do I need Cross Connection Control on my Sprinkler Irrigation System?
It is up to your local water purveyor to specify which type of backflow preventer to use, as outlined in the Manual for Selection, Installation Maintenance and Field Testing of Backflow Prevention Devices. A Backflow Prevention Device (non testable) or Assembly (testable) are the most common.
Have your IIABC Certified Irrigation Contractor from University Sprinklers obtain all necessary permits and inspections on your sprinkler irrigation cross connection as required. Please do your part to ensure that everyone can enjoy the benefits of safe drinking water and ensure the health and safety of everyone in B.C.
Why do I need my Backflow Prevention Assembly Tested Annually?
As with everything that is manufactured, Backflow Prevention Assemblies and Devices break or wear out. By having your Backflow Prevention Assembly tested annually, you will help to ensure that the potable water supply remains safe.
Certified Backflow Assembly Testers in BC attend a rigorous training course, and are certified by the American Waterworks Association, British Columbia Section. They are equipped with the latest in research from the University of Southern California, Foundation for Cross Connection Control and Hydraulic Research. Certified Testers can inspect, test, and repair all Backflow Prevention Assemblies and Devices.
