I'm no engineer and don't have a lots of formal smarts but common sense
tells me if the following is true, then PVC is useless as tits on a boar
hog for any use. 4 psi???
"when you do all the required derates and apply all the safety factors
required for sound engineering practices, 1" PVC is rated to handle about
4psi working pressure."

It works great at what it is intended for, when installed correctly, and
that is cold water supply. The temperature is the big issue, when dealing
with pressure. Any building inspector has a piece of pvc blown up from 3/4"
up to about 3", found after someone incorrectly installed it hooking up a
hot water heater.
