MN Plumbing Code and SPU require backflow preventers to be tested annually. Backflow preventers keep your family’s and the public drinking water safe. Testing your backflow preventer is a critical part of your home maintenance routine.
What is backflow? Backflow is the reverse flow of non-potable water, contaminants or other substances into the potable (drinking) water system. A loss of pressure within a plumbing system that has a failed backflow prevention assembly may allow water to back-siphon into the drinking water supply.
What is a backflow assembly? A backflow assembly is a mechanical device that protects and prevents water or contaminants from flowing backward into the customer’s or the public water system. The most common assemblies installed on irrigation systems are Pressure Vacuum Breaker assemblies.

What is my responsibility as a homeowner with an irrigation system? It is the property owner’s responsibility to have backflow assembly test completed as required under current state code. Expenses associated with installation, testing, maintenance or repairs of backflow assemblies are also the responsibility of the property owner.
What is the risk with an irrigation system? The risk of an irrigation system that does not have the proper, and in working order, backflow assembly is that stagnant water, fertilizers or lawn chemicals can enter the drinking water supply – your own and possibly others’ – presenting health risks. This potentially can lead to liability concerns for the owner and the water supplier.
Can I perform the test myself? MN Plumbing Code requires testing be completed by an ASSE certified tester.
How are test results submitted? We submit test results on your behalf within 30 days of the assembly test date to the water supplier, in the case of Shakopee via The Compliance Engine. As a customer you will also receive a copy of the test results.
