Am I missing something here? Why not just pump thru the FDC connection, leave the clapper in place and hydro as normal? If the ahj wants the FDC tested with the rest of the system, this is the only way to go. One male NST adapter or One adapter and one plug and your good to go. I can see no advantage to all that extra work.

Just the bolt on cover without a clapper (It was in a spec a couple of years ago). We use the CV=1F a lot and I got some replacement covers for the guys to use for testing.
