Are you planning to install a new lawn irrigation system?
The 2015 Minnesota Plumbing Code requires all testable backflow prevention devices installed on or after January 23, 2016, to be tested upon installation and annually thereafter by a certified backflow assembly tester at the expense of the homeowner. Testing ensures backflow devices are working properly to prevent contamination from entering a building's water distribution system.
If you have a lawn irrigation system that was installed prior to January 23, 2016, it is exempt from the testing and maintenance process.
