Minnesota Plumbing Code Parts 603.5.23 through 603.5.23.4 requires <br />backflow assemblies to be tested upon installation and at least annually by an ASSE certified backflow <br />assembly tester to ensure their proper working order. <br />Our records indicate it is time for testing the pressure vacuum breaker backflow prevention assembly at <br />your home, which is tied to your irrigation system, to verify that it is operating within the <br />manufacturer's specifications. Improperly installed or malfunctioning backflow preventers on <br />underground irrigation systems could allow fertilizers, pesticides, animal waste, and other potentially <br />harmful substances to flow into the public water system or be drawn back into the home's drinking <br />water. <br />For your convenience, with the safety of our public water system as the highest priority, ERMU will <br />provide the testing at no cost to you. This free service is offered only to our residential customers and is <br />scheduled to begin May 1, 2024, weather permitting. <br />• You do not need to be home for the test to be completed. <br />• ERMU will need to be able to access your outdoor irrigation plumbing to complete the test (e.g. <br />fences unlocked). We do not need to access your irrigation controller. <br />• The water to your irrigation system must be turned ON, but not running its cycle. <br />• After testing, ERMU will leave a door hanger with your test results. <br />• If your assembly does not pass the test, you will be required to hire a certified plumber to <br />replace or rebuild your assembly at your cost. <br />If your assembly is not accessible for testing please contact ERMU at 763.441.2020 to schedule an <br />appointment. <br />Thank you, <br />Elk River Municipal Utilities Water Department <br />217 <br />
