John, I would add a Certified Backflow Tester (potable water), HVAC contractor & a Fire sprinkler contractor for hydrostatic testing. I would like to know the wording I can use in the agreament with contracters doing additional testing.
Good Morning, The PRV shown in the first post should be piped into the side port of the hot water flush valve or between the hot water flush valve and the tank, not after it, (Ranni Instalation Instructions item 3).
