Backflow Testing
For the health and safety of your family and our community — test your backflow annually. Please note, not everyone has or needs a backflow device.
Some reasons why you may need a backflow device include irrigation systems, swimming pools, hot tubs, boiler systems, or being on a well. Customers with irrigation systems must have a backflow prevention device. Backflow devices protect your home’s potable plumbing system by blocking pollutants from entering your drinking water. Pollutants from the outdoor system can include pet waste, pesticides, herbicides, and fertilizers.
The Oregon Health Authority and OLWS requires annual backflow testing to maintain clean, safe drinking water. For your convenience OLWS has a Backflow Prevention Assembly Testing Program, you now may choose to have OLWS take care of the testing and repair work of your backflow prevention assembly(s). OLWS has contracted with a certified backflow tester to automatically perform this test annually at a reduced cost.
If you have questions about backflow prevention or the Backflow Prevention Assembly Testing Program, please email dave.seifert@olws.org or call (503) 353-4230.
