Winnebago Minnie water supply pipe problem

Help! I cut the water hose to install a pressure tank next to the water pump. But I cannot get a new fitting clamped on the hose without a terrible leak. I already cut the hose and installed a winterizing valve and that accepted the new fittings!
I have attempted three new fittings, cutting about 1/2 inch off after a failed attempt. Two were screw clamps. Two different screw clamps with the same fitting and a different fitting with a cinch clamp which was almost impossible. I worked on this all afternoon and I’m defeated.
Some of the pipe is blue. I can’t tell if it’s pex or not. Does not seem flexible like pex. I have a lot of pex so I was hoping to replace the hose with pex. Does anyone know the type of blue pipe used? I can’t use sharkbites on the hose but I might be able to reach this connection and cut it to accept a sharkbite. It is extremely difficult to reach! But if it would accept a sharkbite connector I could extend from the blue pipe to the tank.

Today it only took about 2 hours to use crimp rings and get the fittings back together. What a project. But it’s done and not leaking. My arms are only a little bruised and scraped. Ha ha.
I fit it all together before I crimped anything.

It took some finagling to get the pipes the right length. I had to cut about a 1/4 inch off this one. Once they were together I had to crimp them. Harder than it looked in this small space with the wire in the way. Some moved either too close or too far away from the fitting. But they don’t leak so it’s ok. Impossible to see even with a lantern so had to crimp by feel.

Thanks for these comments. I wouldn’t have thought to replace the whole pex pipe and next time I have a leaky hose I’ll get a flair- it fitting.
Now we have a pressire tank. I put one in our old RV and it really helps to minimize the pump running for the middle of the night bathroom runs.

True, but the OP would have likely never had to access that area if he wasn’t modifying something. By your logic, they should install residential plumbing outside the drywall for better accessibility?

It looks like if I had bought a flair it compression fitting for the hose I might have avoided the whole problem. Live and learn.
I usuall tighten clamp fittings with a small ratcheting socket. I probably did these but really at this point I can’t remember. Senior brain.

Ok I did it. I cut the pex at the tee across from the water tank. I have a big roll of PEX so I just replaced the whole under floor pipe. That part was easy. But cutting the tee so close to the edge could have been a mistake. Or it was trying to use sharkbites. There was not enough room for me to seat the sharkbites. Then the tee didn’t line up with the third leg so I added an elbow and a pex loop to tie them together. The tee leaked! I have used a lot of sharkbites but I could not remove these! Not even when I cut them out! I have the tool that squeezes them together as well as the plastic ring.

So it was back to removing the crimp fitting from the valve with vise grips and a screwdriver. I bought another crimper with a cutting function by overnight shipping. But of course I could not get it seated in the cramped space. Another hour or so of twisting etc but it came off the valve!
I used the cutting tool to rescue the crimp fittings more quickly.

It’s ready for me to connect with the crimp fittings now. Notice that I disconnected the heat ducts to have more room to work in the box. In the MW 25b all this is under a large storage drawer. I can only hope I don’t have to soak up the bursts of water in the underfloor compartment again.

Ok thanks. It is the white hose that was leaking. I tried both the screw clamps and the pinch clamp. I did not warm the hose as it’s in a very awkward spot. I’m going to get a clamp cutter and try to replace the whole under floor blue pex. Also very close quarters though! I have a whole bag of stainless crimp clamps.

You can't use screw clamps on Pex and you have to use the correct crimp style clamps and crimper (those are wrong).
I suggest Flair-it fittings.

Is the leak at the joint from the white pipe? When you tightened the screw type hose clamps did you use a small ratchet and 1/4 inch socket? If just tightening with a flat blade screwdriver it's probably not tight enough.

Can you access other end of pipe in question? Might be possible to replace to point easier to get to.

Dang! After the initial disgust, I remembered the diagrams are on the Winnebago website! The blue pipe is pex. TUBING 1/2" ID PEX (BLUE)
The question now is how to reach back there to cut out the hose and connector.
