Dear Forum, I've come across a bit of a quandary. In the '07, 8.16.1.1.3.2 allows a backflow preventer to be considered a check valve. 7.1.1.2 says that I have to have a pressure gauge above and below my system check valve. We use Tyco's riser manifold which has a pressure gauge attached. In our typical single wet system riser, we place our backflow on the underground, and our manifold on top of the backflow. So, where would my upstream pressure gauge go? It would seem that my only two options are to tap a short piece of pipe below the backflow, or put a gauge in the backflow test cock. I'm going to verify with Ames, but I'm assuming you can't put the gauge in the test cock without voiding the listing of the backflow. So, am I missing an option? How does everyone else meet these requirements?
