Too Close for Comfort!
This turned out to be a pretty big pain to test both assemblies. The first issue, is with out Swivel Adapters for the test cocks, testing the assembly is not possible. If you are a backflow tester, you need Swivel adapters for the test cocks. The second issue, the test cock adapters from the first assembly were preventing the handles on the shut off valves from operating. To complete the test on the backflow assembly, we had to take off the handles and use a crescent wrench to open and close the second shut off valve. The good part of the story is that we were able to access both check valves and clean out the debris from the check valves. These 2 tests should have taken 30 minutes including paperwork, but instead took and hour plus.
