Best Practice for PEX Supply?

[javelindesign]

Plumbing Pros,

Question - when running PEX to new bathrooms, I generally change to copper pipe about 2 feet away from the shutoffs behind the wall. I do this because:

1) I like to use nice chromed shaft shut-off valves

2) I'm scared of melting the PEX when sweating on said valve...

The practice is a time suck and seems wasteful, so I'm wounding what best practices are here? I've seen nice chrome PEX valves, but I'm under the impression that you'd see a bit of the PEX pipe protruding from the wall? right?

What do you all do?

Thanks in advance!

Jay

screw holdrite to stud, install stub out, solder stub out to hold right, cool
then attach pex


i cut my copper close to the wall, all you see is the valve and Escutcheons

Thanks Frodo - So you always use compression shut-offs? Not sure why, by I've always been under the impression that sweated valves were more secure? I usually use:

something like that with the 5" chrome tube. Have you ever had any compression fitting failures?

have installed thousands, only problem i have is if not installed correctly

my question is why spend the extra bucks when you do not have to

if you put your #15 ridgid cutters on the pipe, and leave 1 finger space between handle and wall

{hows that for a measurement} cut the copper.

a regular stop and eschusion will fit flush to wall with out any copper showing

You can use the same chrome slip covers on the exposed PEX that you use on the copper stub outs.
