Bob We always put them on the #2 shutoff valve, due to the fact that when the backflow valve is being tested annually the #2 shut off valve is shut off for the test and the #1 valve is open and closed numerous times during the course of the test. If it is in a vault the tester has to crawl in and out of the vault numerous times to open and close the #1 shutoff valve to perform the test. Would be easier on a wall PIV in that they would only have to walk in and out of the building numerous times. Depends if you like the local backflow tester. We have several testers on staff so we try to make their life a little easier. Bill Cunningham CET Plumbco Inc

For example in Ohio the water purveyor has jurisdiction up to and including the backflow. Building Dept has jurisdiction after backflow. I would send an RFI to the Architect or send an email to the Water Dept or building official and ask if they care.
