Have been in campgrounds that WARNED of HIGH Pressure
Have been in campgrounds that had as HIGH as 120 PSI in system
Have seen potable water hoses that looked like a python that just swallowed a pig.....and then burst
RV Plumbing system is already a closed system......city water inlet has a check valve that prevents backflow of water from RV to City Water
PEX can handle HIGH pressure...even deals very well with freezing temps.
Fittings used in RV Plumbing system connections..not so much
RV water heaters....air pocket designed into tank to control pressure increases due to swelling of water when heated
Residential water heaters have same air pocket .....air gap in top of tank that is above the water line due to location of HOT Out Dip Tube
Just my thoughts.
