Before I started to replumb the house I compared the crimp, clamp and ProPex (Uponor/Wisbro) methods and settled on the clamp method. For reference the project entailed less then 100 connections. I did have the opportunity to play with the crimps and clamps, but didn't test the ProPex. The cost of the tubing, rings and fittings were all comparable in price.

Crimp: I found the need to calibrate the crimp tool and also the need to test every crimp with the GO-NOGO gage was not DIY friendly.

ProPex: Liked the fact the rings were made out of the same material. Did not like that you need to expand the pipe, rotate then expand again. Expensive, manual expander is $250, auto rotating $400 which would be $4 per connection. No calibration required. Only Uponor tubing. No local source, internet only. If I did this for a living this is the system I would use.

Clamp: No calibration required. Parts readily available locally and on internet. Tool cost between $40 and $150. Get a self calibrating, ratcheting tool. I paid $100 for watts brand.

Spring for a separate tube cutter. The clamp tool has a built in tube cutter, but it is not as easy to use.

Sources I've used: www.pexuniverse.com www.pexsupply.com www.amazon.com (tools) Home Depot (I wanted the orange tubing for return line on the hot water circulator)

Without reading farther, Lowe's has a Kobalt Pex crimp tools with several dies for different sized Pex. It's $90. The 1/2 inch crimp rings are available 50 to the pack for $17. And, if you're only working with one size, like half inch, then you can get the Kobalt crimper for $38.

Lot's of plumbers use Pex...and that's what I have in my home...and I have no problems. I just ran into a retired plumber friend of mine...50 years experience...and still doing small jobs. He asked me what I was using in my remodel. When I told him Pex, his reply was, "That's what you want."

Don't let it hang down...put it up to take the stress off of the Pex and off of the crimps. That was his tip...he says he sees a lot of Pex installed and left hanging.

Hope this helps. Good luck.

I recently ran some new CPVC to replace some Copper runs. To say I'm happy would be an understatement. Very cheap, very easy to put in place. I was considering a few lines of Pex, but I knew nothing about Pex, and with the water being turned off and needing an "asap" fix, I turned to CPVC since I knew it was solid, cheap, and easy. Can't say I regret it in the slightest.

Isn't PEX easier to run because it is flexible? Are there any downsides to CPVC? I am all for it if it is cheap and fast to install.
