AHHH Thanks for sharing that! Any chance you took any pictures along the way??
I have the same issue the main supply line departs my rear storage compartment in two branches, one goes under floor to get to kitchen the other goes behind the shower and there is a white plastic PEX "T" that has Flexible Braided Nylon hose going up to the Shower Valve and that was a "drip point" when I camped in cold over Thanksgiving week. I can see that joint clearly from the rear compartment just no way to reach it at all.....unless I pull the shower wall..... and then I am scared if I commit to going that far that behind the plastic wall will be the luan ply wall and I wont be any closer to reaching those connection points to try and fix them!
So I will say THANK YOU for sharing your effort/results and also encourage you not to get too disappointed...... Our ROO is brand new as well and the water leaks only showed up once the supply water was cold enough to make all those terrible Flex-Poly hose connections with PEX cinch clamps leak... so NOT the right way to make that connection sadly! :-(
I don't know if FR will answer, I am going to try to email and ask them about the selection of the PEX connectors. Our old ROO had plastic PEX fittings as well but all of them were black in color and not white. That old ROO also had some Nylon Flex hoses attached with the same PEX cinch rings too and they never leaked at all. Our new ROO all of the PEX fittings are white plastic and every one of them leaked at the poly connections....so I am wondering if that plastic was different and the cold supply water caused them to shrink in diameter when the black ones on our old ROO didn't...it is the only thing I can think of.
