Welcome to the forum. Although you can post in any forum, the USA forum is here in case of local regs or laws
Nice one Thank you.TBH I would
Each prv has its own run dish and join them all all up after d2
E.g. If they were all in line and close to each other main drain line in 35-42mm (depending on distance) and t off in 22mm to each of them
Hope that makes sense
All PRV's that came with the system are at different ratings so not all are going to pop at the same time, two on the domestic water, one cold in and one hot out, one on the underfloor heating and one on the ground source flow so three systems 4 valves.I would also consider . What's the chances of more than one prv ever blowing off at the same time... It can be quite difficult to keep the routing tidy..
The regs show a tee can be in the line before a Tundish..
