I'm having a new house built and the plumber just put in a parallel distribution PEX system.
He put 3/8"s almost everywhere and I am trying to understand if it will be problematic.
I have runs of up to 90ft, and an unknown rural city supply water pressure (60-70PSI?).
The PEX design guide illustrates the loss of pressure per gal/m per 100 feet.

I did some estimates for my house:
(calculations are for just the single cold supply).
Does this mean if I turn on the first 2 faucets, I will see a combined ~50PSI loss in the system?
From what I read, when a system goes under 40PSI, you will notice reduced flow rates.
This means a 3rd faucet will lower the flow rates of all 3 faucets considerably.
Is this how to interpret water pressure?
Thanks for all your help
