I'm retrofitting an ice maker box behind my fridge. I can patch up the wall, and it's hidden from my anyway.
My Q is regarding pex in the wall--should I be worried about leaks at a fitting behind the wall? I don't expect any movement after it's in, but should I be worried about securing the pex behind the wall at all, it will be about a 3-4' run total from wall to unfinished and exposed basement. Also, any concerns with it being attached to a solenoid valve in the fridge?
I have pex in the basement connected to copper behind the walls and to fixtures. This would be my first/only behind the wall pex, but it will be much easier to snake pex than copper.
My advice is based on anecdotal knowledge or personal experience. I'm not a professional no matter how matter of factly I may say something
Pex is fine behind the wall, in fact I did a similar set-up last year. It should be secured to the studs in the wall like any other plumbing. I used a 1/2" pex stub out 90
and secured it to some bracing I installed in the wall. Then get a compression angle stop, similar to one used on a toilet, and hook it up to a ss braided hose. I got a 4' hose at my local supply house so I can pull the fridge out and do whatever needs to be done w/o turning off the water.
