Pex crimp ring versus compression ring

[Tonebone]

I’m going to replace a 3/4 pex ball valve feeding my water heaters . My whole house is pex, different fastening types throughout. I’m trying to decide on crimp rings versus compression rings. Any insight would be appreciated…….Thanks in advance.

Copper crimp rings work great.

Yep I'll second that

I prefer to crimp. I just did a small galvanized tear out Saturday for a friend and we did copper crimp.

When you crimp do you upsize the pipe due to the smaller ID on the fittings, just wondering.

I do. I run 3/4" all the way. I reduce just before i stub out of wall

I don’t. But don’t use 1,000 fittings trying to “ make it look like art “. It’s meant to installed using the least amount of fittings or keep the fittings to a minimum.

If you over size hot water pipe without out recirculating it, it’s a longer purge to get your hot water.

We have good water pressure in my area, 60-80 psi.
