The clear braided hose is reinforced vinyl, which is exactly what you want on the pump outlet because it minimizes transmission of pump vibration through the trailer via the relatively rigid PEX tubing. Hose like this is clamped onto a barbed fitting by some sort of hose clamp. It should not be clamped by the same sort of ring as used to hold PEX tubing onto a barbed fitting, because those are sized specifically for PEX (and the barbs are supposed to be different types, too, but the vinyl will work on the PEX-style barb).

There are many styles of hose clamp, including the cinched and crimped types of band used with PEX (but sized to suit the tubing). Normally a stainless steel gear band clamp would be used, and that's certainly what I would put on if I were to replace this hose.

If there is enough hose that's unsplit on the water line T end of the braided hose, could you cut the braided line after the split and put in a strait connector instead of playing with the existing clamps? From what I see online, the cutter is none too small, as well as running $60.

Excellent observation and unanswered question....could be the culprit.

Actually I do use a pressure reducer on the spigot head. I also carry a water pressure gauge and checked the pressure on the line at 20+ . I could cut the braided line and put a connector in , but the area is tight, and I am in there anyway, I might as well put some clamps on that I can actually work on when I am camping. I did not understand the PEX clamps on the braided line anyway, and to get the line off and replace it I have to break the clamp on the fitting by the wall. Again no room to work and I would be trying to cut a metal band on a tube connected to a plastic fitting with what?, so as the saying goes "it is better to do it right the first than to have to do it again. Besides isn't that the fun of owning a travel trailer.
Actually my wife was looking at the modifications and found the one for the pneumatic pedestal for the table, so guess whats next.

There is a PEX solid band ring on the flexible braided line? I wouldn't think that there would be a matching PEX band sized for that nor that it would make a good connection. Can you take a picture of it and post it for us? I've only seen that type of pipe with the clamp Brian describes above.

I have used these on flexible pipe on a drip irrigation systems in our garden, but I've never seen them used on higher pressure applications or in a home or trailer.

Any pictures you can take and post of the area you are working on might help make sure we're not providing incorrect advice.

Yes, I recently posted pictures of the accumulator that I added. PEX fittings are used by ETI on the braided tubing BUT as I indicated it is thin wall braided tubing not available in your local hardware store as it has to accommodate the external rings and the internal PEX fittings. I bought some from ETI at $1.50 a foot from ETI the last time I was up there.

Thanks Tim. I hadn't known that that kind of tubing existed. Does it look like it has more reinforcement threads to make up for the thinner walls?

Here's some of my 2014, should be similiar but located in a different spot.

#1 is the braided, it is indeed a pex clamp.
#2 is the other side of the pump, on mine it goes to the winterizing valve and is clear. They used a regular hose clamp on the pump end, pex on the other.
#3 is of all things MOLD, in the line between the winterizing valve and the fresh water tank. Guess I've got to do some sterilizing. There was water trapped between the winterizing valve and the tank in what amounts to a p trap in the hose. Trailers been sitting since May. Guess I need to start blowing it out when not in use as opposed to just draining the system.

Good thing I went to take these pictures.

I don't see a difference, it is just thinner. I did find it from big suppliers but you had to buy 100' so 3' from ETI seemed reasonable. I put getting some from ETI up there with getting some of the oak tape, which I could NEVER find any place. Glad I have a couple feet of that for repairs to the finish on the paneling.
