I have a leak! Shocking! LOL! I think I have narrowed it down to a flexible plastic "bubble" connector. I tried tightening the hose clamps around the connection, but that has not helped. I have not tried putting on a new hose clamp yet. I have been searching the RV parts online stores for the plastic bubble connector but I have not been able to find one. Does anyone know where to get one of these connectors or have an idea for another option?

As you can see, the water did some damage that I took out. I am not able to use my potable water tank because of the short vertical hose that is attached to the potable water tank hose AND the city water intake. Arrggh.

This is a 1996 Terry TT.

I don't think that's supposed to be a bubble.
Looks like it's swollen from pressure.
Make sure you have a pressure reducing valve on the hose outside of your unit. Most city pressure is too high.

As to your leak, you just need a new piece of hose. Maybe a piece of PEX from Home Depot.

I would just replace that piece with a whole new piece of hose with new clamps. Sometimes the plastic hoses just break down and need to be replaced.

Thanks for the quick responses! I am a newbie and bought the trailer from a couple about 5 weeks ago so I am discovering all the things that are wrong with the trailer and learning how to fix them myself if possible.

Is there an easy way to get that plastic hose off? It seems to be on quite tightly.

You can probably just split it with a razor knife after you take the clamps off. Be sure to get new clamps that fit the new hose, those clamps look to large for that size hose.

I was able to remove the old and install the new clamps and PEX pipe. I tightened the clamps as much as could, but I have made the situation worse with installation of the new. I did take the old PEX in to the hardware store to make sure I got the right size and bought smaller clamps.

Are there any tricks to get a tight fit?

Thanks in advance!

I wonder if pex is to stiff to use with hose clamps.

j9fortier · 07-09-2015, 08:19 PM

The old that I took off had ribbing on the inside of it. PEX seems flexible enough, but then again, I am learning, so I have no idea how to get it tighter.

Take the whole assembly off the trailer including the city water connector and bring it with you to Home Depot or a pluber. You should be able to get a good seal.

TDI-Minnie: What do I accomplish by taking in the whole unit? I took the old piece of hose with me to True Value to match the size. I have two connections to get tight inside the trailer. I am trying not to have to haul my trailer to an rv repair shop.

You can't use regular clamps if you are going to use PEX pipe. PEX uses a special type of band clamp and take a special tool to install them. Most hardware stores should have the band clamps and tool.
