I bet an oscillating saw with a blade for wood with nails would be the best way to cut copper rings off pex. I will have to give it  a try. I just got a Dewalt 20v one and can't believe how good it works.

I think the one case of leaking SS clamps it was an issue of off brand clamps with the wrong tool. They switched to oetiker brand and had no further issues.
Pex is really an amazingly reliable system.

I got some cheap no name ssc tools that Nature's Comfort was selling. They didn't properly crimp the clamp and a few leaked. I just recrimped the same clamp with a good tool and they never leaked again.

I only use those tools to break clamps now.

There was a lawsuit against Nibco awhile back for supposedly there brand of pipe failing at the fittings.

I found one article that stated that the whole nibco pipe failure was Pex C that is much less resistant to water quality issues. ?

I run into PB tieing into older water heaters in double wides, gotta couple to it somewhere. Crimp gently....
Ran into a similar problem tieing in to the hot water heater and main cold supply here. It's  double wide plumbed with Qest pipe which is totally odd ball to pex. My solution was archaic at best. We heated the PEX and it would slide right on the Qest fitting but no crimp rings I had would work so next best for me was a wide worm gear clamp.  I've repaired Quest to Quest in mobile homes for years with clamps and they are still holding. I hope this variation holds for a long time ;D

You can get a Quest x pex adapter coupling at Lowes or wherever made for that situation.

Just did an install at Emory, not far from you? Got to fish South Holston this summer. Them Walleye and Smallmouth are calling.

Hey there!

We are almost neighbors  ;D
I used to use those Grabber brand fittings with Qest but they got hard to find for awhile.  My method was definitely not an approved method but thankfully it has held for close to a week. We are so dang far from a Lowes or similar place that when we ran into this situation we couldn't make it to the store and had already cut the pipe >:(  That figures don't it LOL!

Speaking of South Holston I remember several years ago I was called to check a vhf radio in a yacht of sorts, big ole boat anyway  ;D
The owner wanted to go out in the lake a ways to verify my repair and I agreed. That was the first time I had ever been so far out in the water where I couldn't see any land and I was nervous as a cat on a hot tin roof  8)  Long story short the radio worked fine and I was very happy it did... in case I had heart failure!
