PEX to copper drop elbow for hose bib.

[Alex_T]

Hi everyone, looking for some help in regards to my garage hose bib I am completing.

Last year when we were having an extensive renovation done, I decided it would be a good time to install a hose bib into my garage given that our interior walls were down to studs.

I installed a copper to PEX drop elbow that I guess would be installed upside down (PEX leading down through the framed Wall into our crawlspace, copper leading out wall into garage).

I then had our plumber complete the PEX in the crawl space with a shut off valve and a drain for the line. The drop elbow is now closed within the wall that has now been spray foamed and drywalled, so I do not have access anymore.

For the last year I have left the stub out untouched in the garage and would now like to attach a hose bib. My soldering skills are not the greatest, so I am considering using a shark bite bib. My concern with this is the fact that they seem to spin on the copper once installed.

Is this something I should be concerned with? Does the rest of my setup seem acceptable?

Also, I am not sure if the plumber ever inspected for leaks, and I am a bit concerned now that the one copper-pex connection is buried in the wall. Are these connections usually pretty reliable?

Thanks in advance for the help and advice!

Also I should add, I will be installing an anti-siphon vacuum breaker to the faucet. .

A drop ear elbow usually has a FNPT thread. What comes out of the wall now? Is it 0.625 OD, or is it 0.84 OD?

I used one of these, https://www.homedepot.com/p/Apollo-...Degree-Elbow-with-Flange-APXSTUB8WE/301774431

Probably should have used a threaded elbow, too take now I suppose.

That is called a stub-out.

Make sure that you drain before freeze.

I was looking for a non-frostproof anti-siphon spigot with compression fitting, but I did not find one.

My mistake, plumbing is somewhat new to me!

I have the drain immediately after the shutoff valve, downhill from the hose bib inside our heated crawl space.

Any concern for having the spigot rotating due to using a shark bite?

Thanks for all the advice!

I am not a plumber. I would be a bit concerned. Here is a compression type that is not anti-siphon:

In using compression, it takes a fair amount of torque. I think fear of crushing the copper is way overblown, unless your wrenches are very long.

Here is how it ended up. Secured hose to garage shelving. Think this should be okay?
