Yeah, plastic fittings are always a gamble—tighten just a hair too much and you're back at the hardware store. I've stuck with metal fittings whenever budget allows. Haven't tried sealing cords yet, but quality tape hasn't let me down...yet.

Totally feel you on this. I've had my share of plastic fitting nightmares...ended up switching to metal fittings too, and honestly, it's worth the extra cost in the long run. Tape's been reliable for me as well, but I've also had good luck with plumber's putty—especially around tricky joints. Might be worth a shot if tape ever lets you down. Hang in there, plumbing issues test everyone's patience eventually.
Have you checked if the plastic fittings you're using are rated for hot water? I ran into a similar issue a while back—kept getting tiny leaks no matter how careful I was. Turned out the fittings weren't designed for higher temps, so they'd warp slightly over time. Switched to metal fittings and haven't had an issue since. Might be worth double-checking the specs on yours...could save you another frustrating trip to the hardware store.
Had the same issue a few months ago. I double-checked my fittings, and they were technically rated for hot water, but still warped slightly over time. Ended up replacing just the fittings closest to the hot water line with brass ones—didn't break the bank and solved it completely. Might be worth trying just those first to keep costs down...
Had a similar headache last year, but replacing fittings didn't quite do the trick for me. Turned out, the real culprit was actually subtle vibrations from the dishwasher next to the cabinet. No joke—it was causing tiny shifts over time and loosening everything up. Ended up adding some foam padding around the pipes to absorb vibrations, and it's been bone-dry ever since. Might wanna check if there's something else rattling things loose under there...
