2021 FR3 maximum water pressure?

[RVwino]

Hi,
When I install a 40psi pressure regulator on the campground source, it reduces the water pressure way too much for a good shower. I searched the owner’s manual and also the web and can’t find the maximum allowable pressure. I can find lots of opinions on the web from 40psi to 100psi to “don’t worry about it”. Has anyone seen an FR spec for this?
Thanks,
Cliff

Ive not see an official Spec, but I have seen expert advice RV experts recommend you never let the water pressure exceed 60 psi and the 50psi range seems to be the RV sweetspot.
one item of note I own a Truma AquaGo and they recommend 40psi-44psi. i just spent 8 days using 43 psi with an Ecocamel showerhead and it was enough pressure and no leaks.

50 Psi is definitely a sweet spot and water pumps are often set to shut off as high as 55 psi from the factory.

Water system test pressures are usually 80 PSI but that's for testing, not operating pressures.

I've found that 40 Psi is a little wimpy for my taste and 50 Psi is just right.

An adjustable regulator with gauge is a good addition to one's "kit" to make sure there's enough pressure for a nice shower but not so much the system is overstressed.
