Hello I have a newly built home that came with a DWHR pipe. The home is fairly large and has alot of plumbing. 3/4 " supply's most of the initial runs and eventually they branch 1/2" PEX.
My question today is regarding supply problems. If I run 2 things at once (both 1/2" outlets)e.g a bath and a garden hose simultaneously the GPM on them becomes painfully bad.
One thing in perticular that is catching my eye is how everything (hot &cold ) is first piped through a drain water heat recovery unit. 30ft of 3/4" to the unit and then 30ft to the hot water tank or out to other cold outlets. The DWHR says on it 1.9 psi loss. But what about all this extra length of piping? Could this silly unit be killing my supply?
Please help.
