Home Depot usually has a better selection of PEX hardware. I cut the old fittings off the PEX pipes and installed
PEX shutoff valves--that way I didn't need an adapter. I personally don't like the adapters. I highly recommend
cinch clamps and not crimp rings--I think their much easier to work with and your
clamping tool is smaller. I installed a
Delta Savile and love it. The picture shows a cover plate, but obviously it's not needed. The soap dispenser is nice to have.
