I am not using my irrigation system anymore. Do I still need to test the backflow assembly?: As long as the irrigation system is physically connected to the water system, your backflow prevention assembly must be tested. Puyallup Water will suspend the testing requirement if the customer provides a physical disconnect between the irrigation system and the public water supply by removing the backflow prevention assembly and capping the water supply line. You must contact our Water Quality section at (253) 841-5524 to arrange for a verification inspection once the line has been capped.

2. Why do I have to test my backflow prevention assembly every year?: Backflow prevention assemblies protect your drinking water from potential sources of contamination. The only way to ensure they are working properly is to have them tested by a certified backflow assembly tester (BAT). The Uniform Plumbing Code (Section 603) and the Washington Administrative Code (Section 246-290-490) require annual testing of installed backflow prevention assemblies.

3. Who can test backflow prevention assemblies?: All backflow prevention assemblies must be tested by a state of Washington Certified BAT. Puyallup Water provides a list of testers to our customers. This list is not a recommendation - just a list to help you get started. You can find additional testers on the Washington Certification Services website.

4. I have my backflow assembly tested every year as required, but my neighbor says he has never heard of the testing requirement. Why is that?: There may be several reasons why your neighbor has not received any test due notices from Puyallup Water, the most likely being that we don't know about the installation. Many times customers make modifications to their water system and do not take out the required permits. Taking out a permit ensures that your work is inspected and installed to code. Most importantly, it ensures that you, your family and, if applicable, your customers are protected.
