Before messing with the PEX clamps/fittings check the tank nipples.
Your type of valves rarely fail stopping flow when opening.
If they fail it's usually that they don't fully close and leak thru.
When you open hot out valve and get flow then it stops sounds like the symptoms of a check valve problem.
Some rv builders installed check valves even with the 3 valve systems.
Even put them in the cold inlet nipple vs hot outlet nipple.
Next time out to trailer........open WH tank PRV via lever then turn on pump.
If you get steady flow out PRV then cold inlet isn't problem. One less thing to check/worry about. Then you problem is on hot outlet side
He said he had flow from the PRV. The hot supply valve is suspect. Whenever I replace I use 1/4 turn ball valves.
OK.....missed that on initial post
Still think the problem is at the tank outlet and not with the shutoff valve
Could be. In 15 yrs of 5th wheels I've never had this issue so I'm not sure theres a check valve in that fitting or not.
