Ok, Don't you find it odd that RV companies are using PEX, which is rated over 100PSI?
I see this quoted on here many times that you must use a regulator, blah blah blah, funny, if you talk to the RV companies they pressure test the lines with air at 100PSI.
They rate the pressure to be 30-50PSI for warranty purposes.
So what in a travel trailer would dictate that you couldn't use more than 30PSI of water pressure?
I really want to know. Outside a lack of a check valve at the 12vdc pump, what is it? What plumbing part in a travel trailer can not handle 60-75PSI of water. 99% of all culinary water systems in uses are not greater than 75PSI. Added to that, if you have a filter connected to your incoming city water connection, you most likely will not be able to use a pressure regulator.
Also, many RV parks have the regulator built onto the line already, most in Oregon do.
So until someone can point out the exact component that can not take more than 30PSI, I say it is bunk.
There is a lot more to plumbing then just the pipe / tube. I agree 30 PSI is a really low rating, but it could be the toilet valve, the plastic faucets, light weight elbows / fittings...
BTW, I have zero pex in my trailer, it is just unmarked semi-rigid plastic tubing, I can't find a single rating on it. Maybe your trailer is rated higher.
My last house had 110 PSI of water pressure at the inlet (city water)
My current house is capable of over 200 PSI from my well sending pump, but I have it at 90 PSI due to the PEX piping.
