Why yearly Backflow Testing is required?
Effective after January 23rd 2016, the Minnesota Plumbing Code requires that all testable backflow devices be tested upon installation and at least annually thereafter. The purpose of your backflow device is to keep the outside water to your sprinkler system (which may contain contaminants such as fertilizer, pesticides, etc.) from entering or backing up into your household drinking water. The Backflow Testing is fairly simple, but it is important as the purpose of the inspection and test is to ensure the backflow is functioning properly.
How do I know if my city requires this test?
Your city will send you notification when your test is due. If you haven't received a notice, and are still unsure, call your city water department. However, some suburbs receive their water from a water company, so the requirement would be from them, not the city you live in.
When is the test due?
This varies from city to city, but it is due yearly. The best time to get the backflow inspected is in the Spring when the Sprinkler System is being used.
Wouldn't I know if my backflow was not working properly?
Absolutely not. Depending on the extent of repairs needed, your sprinkler system would continue to work. The only way to know with any certainty is to have the system tested.
Who can perform this test?
While a certified irrigation installer can install your backflow, he cannot test the device unless he is a state certified backflow tester. Your city will not accept a test performed by anyone else.
Am I exempt from this annual testing if I no longer use my sprinkler?
Some cities require that backflow be tested yearly, regardless of it's usage. Check with your city.
Am I exempt from this annual testing if my system get installed PRIOR to Jan 23rd, 2016?
You could be exempt! But, I would suggest to contact your city/water municipal to confirm.
What if I just ignore the require backflow testing?
Not advisable. They have the ability to disrupt water service to your home until you comply.
