PEX Questions

Those of you have used it, is there much difference between the crimp ring, pinch ring , or sharkbite connections? I see in other threads where Sharkbites are discussed and how expensive they are. I found 1/2" PVC lock fittings for $2. Seems like the easiest way to accomplish connections. Any downside to these? None of it carries much pressure.

I have used Sharkbite.

They work great and they are very easy to install. So easy that, when I did the first ones, I though I must have done something wrong because it was so easy.

After I win the lottery, I will only use Sharkbite.......... Yes they are expensive.....

I've started to do some research, and from what I've seen, the SharkBites are $$$, and can really only be used once or twice without compromising them at least somewhat. They are also the least strong, but for low pressures, I don't know if it matters. Depends if you're connecting to other water supplies, or just filling your tanks, I suppose.

I'm no expert, but the strength of the crimp and clamp rings seem far better than the actual PEX tubing, so shouldn't be any issues there. The crimp locks into place so you can see it easier, so for me, that's worth the extra few cents per fitting. YMMV

Let's see what some plumbers have to say - are we on track, or is this bunk?

I forgot to post the link. When it comes to cost, $2ea for the ease of this product is not what I would consider expensive. The max pressure of the pump is 40psi. These have a working pressure limit of 150psi, with a 600psi burst pressure. I think it's a no brainer on this one. This product in PVC has locks on both ends, Sharkbite brand only has the lock on one end. And are more expensive.

As long as you chamfer the end of the pipe they are reusable many times, but ow many times do you plan on disassembling the joints? Removal tool is cheap also.

The weak link in the chain will be the PEX itself which is only rated at 100PSI at 180*

Sharkbites are amazing...I use them for repairs only due to cost and always have some on hand. About 7-12 bucks per fitting.

Pex and crimp rings are cheap. The fittings come brass or very inexpensive plastic. The pex tool can be pricy, and hard to get into tight areas. (though they make a smaller one for use with visegrips)

I have not used the pinch clamps and their less expensive pinch clamp pliers (because I have a couple crimp ring tools).

Plumbing is so quick and easy and cheap with pex (Oh, the old galvy pipe in my childhood home...)

BTW pex can withstand some freezing, but NOT the fittings!

Some freezing is right

I had PEX freeze in my first bus. I was concerned about I splitting.....it didn't....

Then it froze again and I was not so concerned. It did not split.

Hey, this stuff is indestructible!

Well.... The fourth time I got a waterfall in my kitchen.....

When I got away with it the first time I got complacent..... Lesson learned.

If specs exceed the application specs whats the concern for indoor hot water @40PSI ?
