I've used push-fit fittings near my boiler for about two years now—no leaks yet (knock on wood). Just make sure you prep the pipe ends properly and don't skimp on quality fittings. Saves a ton of hassle compared to soldering copper...and fewer burnt fingers.
I've had mixed luck with push-fit fittings myself. Used them in my bathroom remodel a few years back, and while most held up fine, one fitting near the hot water line started dripping after about a year. Ended up switching back to soldering copper there—burnt fingers and all, haha. Guess it depends on your comfort level and maybe a bit of luck...
Had a similar issue when I helped redo my parents' kitchen plumbing last summer. Most of the push-fits worked great, but one stubborn fitting near the dishwasher kept leaking slightly. Ended up soldering copper there too—sometimes old-school methods just feel safer...
I get why soldering feels safer, but honestly, I've had pretty good luck with push-fits—even in tricky spots. The key for me has always been prepping the pipe ends really carefully: deburring thoroughly, making sure they're perfectly smooth, and double-checking alignment before pushing them in. Had a stubborn leak once too, but after redoing the prep work slowly and carefully, it sealed up tight. Old-school methods are reliable, sure...but sometimes patience and prep can make newer fittings just as trustworthy.
Had a tenant once who swore by push-fits...until one popped off at 2am. Lesson learned: they're great when done right, but always double-check your prep work. Glad you sorted yours without a midnight flood!
