About to commence installation of a remote manifold in a tri-level home.
pex-a/propex/expansion pipe
The bathrooms and laundry are all stacked at the same location.
Laundry hookups
3 sinks
2 showers (w/ body jets)
1 Tub
2 toilets
9 cold ports 7 hot ports.
The hot manifold will be open leading back to the Navien boiler (ncb-240e) through a circulation pump (Taco smart sense)
With the showers having body jets (10 total) pressure drop is my greatest concern.
I am split between a 3/4" supply Line and a 1" supply Line. I would like to do a 1" to reduce any chances of pressure drop but will that put unnecessary work on the boiler with recirculation?
3/4" return for recirculation?
I realize the fixtures are all 1/2" or less but would running 3/4" to them assist pressure?
I can get a 7/9 port manifold with 3/4 propex outputs.
Also considering combining toilets/laundry cold outputs as pressure isn't of concern.
Only other fixture requirements is kitchen sink hot/cold which is close to boiler. Tee off before or after manifold?
Final question on the recirculation return to the Navian. Best to tee into the 3/4" DHW cold water inlet supply?
Sorry for the long post,just want to do this right while I have access to everything during remodel.
Thank you all in advance.
