Question Of The Week: Annual Testing And Maintenance Of Backflow Preventer

Posted by Heidi Schwartz

This week’s question comes from the Facility Executive group on LinkedIn.

question of the week logo.

Can anyone provide me with a reference in regard to backflow preventer testing? I have one installed within my water glycol piping system, and it hasn’t been tested since 2012. I thought this was supposed to be an annual test.

Any information regarding maintenance would be appreciated.

  1. I didn’t realize that backflow testing services should be done every year. I will have to make sure I keep on this for my own system and keep it running properly. Thanks for the heads up.

  2. All commercial backflow preventers used for fire sprinkler systems and domestic water connections must be tested annually, while residential irrigation backflow devices are required to be tested at least one time every two years. These are the typical rules for most municipalities, as they control the water utility plants. It’s best to contact your local water supplier for their specifications.
