Flexible PEX hose.

Well I found a couple of spots in my RV where the highly trained factory technicians just forced the vinyl tubing on without barbed fittings and hose clamped it. How did I find these spots, by looking for the leaks of course.

Yeah but I could never get PEX clamps to work with vinyl tubing, you have to use barbed fittings and a regular hose clamp.

Yes that is what I used also. I got tired of my poor water pressure and dropped the underbelly and found the hose between the tank and pump kinked in 2 places.

Hose is available from eTrailer as well as many RV stores. I have never seen a proper 1/2 PEX to 1/2 hose adapter. Just because the RV industry clamps hose to a PEX fitting does not make it right. You need a hose barb that is larger and a different shape to connect hose. I find it funny that they say that an RV is tested to a certain water pressure while containing these mismatched components. A fitting that might work for you is this one, although still not correct. A hose should be connected to a barb such as this.

You can get fittings that will adapt from PEX to standard braided vinyl tubing held on with hose clamps. They have lots of tubing connectors in brass or sometimes nylon like these: Amazon or look thru this page for ideas PEX to Tubing
