"Curious though, anyone tried those push-fit fittings specifically rated for behind-wall use?"
I've used them a few times, and while they're convenient in tight spots or quick fixes, I personally wouldn't rely on them behind walls long-term. Call me old-school, but crimps or expansion fittings give me more peace of mind—fewer callbacks, fewer headaches. If you're set on push-fit, just make sure they're specifically rated for concealed use and installed exactly per the manufacturer's instructions. Nothing worse than tearing open drywall twice...trust me.
Agree on this one. Push-fits are handy under sinks or somewhere accessible, but behind drywall...I dunno. Even the ones rated for concealed use make me uneasy. I've seen a couple fail—not fun. Crimps or soldered joints just feel safer long-term. Plus, inspectors around here tend to trust traditional fittings more, fewer hassles during inspections. Just my two cents.

Yeah, learned that lesson the hard way last year. Had a push-fit behind drywall in my laundry room—thought it'd be fine, but nope...ended up tearing out half the wall after a slow leak. Now I'm strictly solder or crimps for hidden spots.

Yeah, push-fits behind drywall always make me nervous too. Had a similar issue under my kitchen sink last summer—thought I'd save time with a quick-connect fitting. Worked great for about three months, then started dripping slowly enough that I didn't notice until the cabinet floor warped. Now I'm wondering, anyone tried compression fittings long-term under sinks? Curious if they're reliable enough or if soldering is still the safest bet.
Push-fits hidden behind drywall are just asking for trouble, honestly. I had a similar headache last year—thought I was being clever with quick connects under the bathroom vanity. Worked fine for a while, then one day I noticed a damp smell...opened it up to find a soggy mess. Switched to compression fittings after that, and so far they've been rock solid. I'd still trust soldering more behind walls, but for under sinks, compression fittings seem reliable enough to me.
