I too prefer the stainless pinch rings over the crimp press rings. But the expansion tool is the way to go. My plumbing store here (Ferguson) has loaner tools if you buy your materials there. To use expansion fittings you have to use the right type of pex. Can't remember if it's type A or B, but the cheap stuff Depot sells here isn't compatible with expansion.

Bob, Sharkbites have their place but 2 issues: First is cost. With a little practice crimp fittings are just as fast as sharkbites and way cheaper. 2nd is code: Sharkbites are illegal inside walls in some states. Only allowed where accessible. Something to check.

This is what I’m dealing with. Electrolysis is eating every brass fitting in the house from the outside in. I will start this weekend replacing every brass fitting in the house with plastic pex fittings. They only lasted 19 years. I’ve used pex for years and love it. I did switch a couple years ago to the SS clamps instead of the copper ones. Water in the basement on your anniversary is a bit of a buzz killer

Furstroker what is that tools name?

Did my whole place in 3/4 to 1/2 pex.
Great except the pressure at shower and sink.
I plan a redo of some larger tube, another bladder tank,
and I have an extra pump but not sure it's needed.
Though the ejector is suspect.

Somethings not right, plenty pressure from garden hose connected near tank
but further on pressure sucks.
A volume thing perhaps.

I'd hire someone if I found that guy.

It's a Sharkbite brand that i picked up at the Home Despot.
