YUP . completely LOL.
Guess I will try to eliminate the flair fitting, seems I have almost everything else I need except that one.

Found at Lowe's. The elbow though has threads all the way up to the end, while I needed one with the little bullet looking end. I found one in my supplies that will work. Tested the toilet, it works fine. It has 3 line which aI couldn't understand, but if you loop the plastic lines together and hook the input to the brass connector it all works. Almost have this job done....thankfully it has been as everyone here said,the hardest part was removing the old copper.

Happy for progress

Alan, It's good news that you have had good weather to work on your project and able to get the toilet working for Springsteam. There are enough folks coming to Hawassee to keep you from going hungry. Priorities first.

YEA! I am s glad to finally get the plumbing almost completed. It took me awhile to sort thru all the weird different connectors I had no clue about. I know a whole lot more now.
Still gotta do the outside clean up, but that will start later. Also have to figure out what I am doing for a/c.

A couple questions as my polypropylene has sprung one leak and will now be replaced.

29 foot 89 excella.

1. Where it enters fresh water tank, does this just pull out?
2. In middle ( between kitchen and closet) they run underneath to the bathroom on the other side. Is it necessary to access this from below or just feed it through from the top by connecting each to the old and pulling it through?

PEX barbed fittings and hose clamps

Has anyone tried using just hose clamps to secure the PEX pipe on barbed fittings instead of the crimp rings?

Personally, I can't see the crimp hose clamps providing much more force and the hose clamp would be removeable.

Thanks....

I have used hose clamps on pex pipe with barbed fittings in temporary situations. It did not leak.
However, I think this would void the manufacturers warranty on the pipe. I would not use a hose clamp and cover it up in a wall. Anyway, the crimp fittings are cheaper and faster once you have the tools.

Pex is usually a bit stiff for hose clamps to be effective.

Crimp is OK for manufacturing where you can set up a jig and the capital cost of the tools is minimal compared to the other costs in the run.

For repairs and in-site replacement where just a few joints are involved (such as re-plumbing a trailer, fittings such as the Flair-It found at most corner hardware stores or iplumb.tv work well. The *byte are also OK but they tend to be more costly, more bulky, and don't have a definitive grab.

The Flair-it fittings have a barb on the inside of the pipe and a nut used to crimp the pipe down on that barb. They are easy to use and can easily be tightened or removed and re-used.

Does anyone know if I was doing something wrong? I used the $30 clamp from home depot that has multiple sizes and when clamping down the brass ring on 1/2 inch is was ridiculous. I'm pretty strong and using a 10 inch channel lock did not tighten it up enough. I literally had to put pipes on the end of the handles to get about 20 inches of leverage to get them to "go".

fishandfly - Try using vice grips next time - much easier.

The "pocket crimper" is all I have ever used. I have a dedicated Vise Grip (the real thing - not a knock off) that is in my Pex bag and have never had a failure. It admittedly gives even the Vise Grip a workout to get a "go" instead of a "no go" on the test gauge but I have had all kinds of fun with Pex since I got those tools. Even put Pex (1/2" shoved inside 3/4" to make a stiff 18" rod) "poles" on my fishing boat trailer as guides so the boat slides right up the middle when loading from the lake. Works like a charm.

This is a great thread. A great resource for my future PEX project.

I tried a vice grip (8" I think) and it was clearly too little leverage.

What size of vice grip do you use? Also, why does a vice grip help at all over a channel lock? I would think the pressure needs to be applied at one instant to crimp it down. I wondered that when I saw the vice grips being used on the package too.

Thanks!

I think I have an 8" Vise Grip that I used with the Pocket Crimper. I have noticed that when I put the crimper pieces together and squeeze them by hand down onto the copper crimp ring, they can be squeezed together so that the crimper just "hangs on" even if I let go to pick up the Vise Grip. Then the Vise Grip gets a squeeze, and sometimes let go, twist a bit on the adjustment to tighten, and another squeeze. That does the trick, we get a green light GO from the test gauge and it's on to the next one.
