Calling all plumbers- PRV on main and Expansion
Got a 6 unit apartment with abound 100 psi- need to drop the pressure some. My question- why do some PRVs tend to make the P&T valves blow off some pressure (without an expansion tank) and other PRV installs don't?
This building has 6 basic gas water heaters, 30 gal. It would be a bit of a pain to install 6 small exp tanks, so perhaps i would throw the dart at the wall and guess at a good sized 'medium' tank
