what tools for pex

my son has pex plumbing in his house and I am not familiar with how to work with it. it is half inch and three quarter. what tools does it take to remove old fittings and replace with new ones. disconnect and old crimped fitting from and shutoff and crimp on a new line. thanks

If there crimped I use my Dremel tool with a cut off wheel to carefully cut the band, making sure to not cut into the PEX.
I bought the special cutters for doing it and never could get it to work.

As mentioned, they make a special removal tool to remove the crimp rings, but they can also be cut off by other means. You can also just cut the pipe and install a new section. You'll need a pair of pipe cutters and crimpers to start. There are two types of crimp rings, which will determine what type of crimp tool you'll need. If not experienced plumbing with Pex, then I'd recommend getting a ring gauge as well to check your crimps.

I know Lowe's and Depot carry them. I can't comment as to which type of crimp ring is better than the other. There is a special type of pipe cutter for PVC, Pex, etc. Like this one: https://www.amazon.com/TEKTON-6466-P.../dp/B000NY4THS

Here is a great resource that should answer all of your questions: https://www.pexuniverse.com/types-of-pex-fittings

Excerpt from that site regarding the two connecting methods:

Q: Which is better – clamp or crimp method?
A: We sell about an equal amount of crimp rings and cinch clamps. Clamps are growing in popularity since they are easier to install and the PEX cinch tool is more compact then the crimp one, allowing to make connection in less accessible locations. In addition, cinch tool is universal and works with all clamp sizes, whereas crimp method requires a separate tool (or a change or tool jaws) for every PEX tubing size. However, crimp method offers a somewhat more uniform and easily gauge-able connection, and has decades of proven performance, which makes is a popular choice among professionals and DIY’ers alike.
Sounds like the clamp style is the more popular of the two.

Those are your only two options. The clamp method seems to be the most convenient and only requires one tool.

My experience has been completely with the crimp rings, which work great. So I can't really say which is better.

Either way you go, you should get a 'Go/no-go' gauge. This is a little metal piece that you put over the crimp/cinch ring every 5-10 crimps to be sure that you're crimping sufficiently. Sometimes the tool can get out of whack, and not crimp/cinch 100% correctly. It's rare to happen, but something you'd rather catch as you're making the connections instead of a few years down the road.

Go - No/Go gauge:


Many different companies make them, but they all work the same.

Go with the copper crimp rings. Dont use the cinch steel ones.

Get a tight spot too. it pulls back and jaws open better.

Get the ring removal tool. It works best. dont waste time with dremmel.

What type system does he have now??

Now I got these and cost me about 80 bucks each.. I know there are cheaper versions. but I don't usually buy cheap when it comes to tools.
