Ugly pex stub to copper

[Rations]

Hello!
First time posting.

The plumber before me left 3/4" pex stubs out of the stucco wall to connect to a tankless water heater.

It's pretty ugly and I don't want to rely on the durability of white pex exposed to the elements.

Any ideas how I can secure the pex inside the wall, tie into the copper line to the water heater, and secure the copper to the stucco in a way that looks nice?

I was looking for a copper flange with mounting holes that I can connect to pex but I haven't found anything yet.

Any help is appreciated,

Thank you!

Is the water heater outside the house??

Yes. Outside back wall

one way we stub copper is just copper sweat brackets from Holdrite

Another way is with Holdrite bar bracket or single bracket that utilize their lock-n-load clamps. That was no "plumber" to have PEX exposed outdoors, that was an idiot and if licensed should be reported to CSLB if he/she/it doesn't return to fix for free.

Thanks for the reply.

What do you think about cutting a short section of the sweat bracket and mounting it to the exterior wall, sweat the copper to it outside wall, connect it to pex, then push pex inside wall?

Then maybe put an escutcheon over it?

Yeah the previous "plumber" came in, did some messy work, then dissappeared...

Partly a problem with the project manager oversight. He let things get messy and the subs that came are starting with problems to fix.

Whatever you do, make sure any PEX that was outside the house is cut out and replaced with either copper or new PEX. You do not want that UV exposed PEX inside the wall.

Looks like pex is rated to withstand uv for 30-60 days.
I'll check with the project manager how long it's been exposed. Thanks for the idea

The only trouble with cutting the sweat bracket is that is just plain steel under the thin, cosmetic copper plating. So, one would just want to prime and paint so it doesn't develop rust (just cosmetic)

Oh ok thanks.
I'm tempted to cut the wall open and Redo the drywall but it was just finished and the customer just moved in so it's very crowded and busy in that area inside the house.

That's what needs to be done to properly fix this. The minor inconvenience is better than a major one when there is water damage and an insurance claim.

One option to keep the PEX protected is to install an escutcheon plate or a wall flange around the area where the PEX exits the wall. You can transition to copper immediately after the PEX leaves the wall using a brass PEX-to-copper fitting, then secure the copper piping to the wall with pipe straps. This not only improves the appearance but also protects the PEX from UV exposure and potential damage from the elements.

Thanks for the reply. Do you have a flange in mind? I couldn't really find anything that would look ok and hold secure while transitioning from pex to copper
