Water Pressure in a RV?
I've always believed that water pressure in a RV should be around 40-50 lbs - and that is what I set my Watts pressure regulator to produce.
An acquaintance has told me I am nuts and going to blow out my water system. I kinda of don't think so, since it is mostly pex.
Any other opinions out there?
Thanks,
Jerald Pendleton

While I can't prove it but me thinks your acquaintance is wrong.
My Shurflo water entry has a built in 65 PSI pressure regulator:

Almost every fixed aftermarket RV pressure regulator is 40-50psi, so methinks your friend is wrong.

Not sure if your acquaintance is correct about you being "nuts" but he is wrong about the water pressure. 40 to 50 is fine.

My RV regulator is set for 65 psi. Somewhere I read RV are built to about twice that, but I just couldn't find the article.

40-50 is good. 65 is ok on a newer RV with PEX (red or white or blue). Older RVs may have polybutyl (grey) and that is usually ok at 40-50 but 65 may have leaks at joints.

I have my Watts set to 45 psi as well. Many have it set at 60 psi or thereabouts.

My adjustable has been set to 60 psi for four years. I have read (unconfirmed) that Newmars (and possibly others) have been tested to 100 psi at manufacture.
