Had this stubborn leak under my kitchen sink for ages, you know the kind that slowly drives you insane? Anyway, grabbed one of those sealant thingies at the hardware store—wasn't expecting much honestly. But hey, it actually worked pretty great, no more drippy-drip sound at 2am driving me nuts. Wondering if anyone else tried these kinda products and found them surprisingly effective or if I just got lucky this time...
Those sealants can definitely be handy for a quick fix, but honestly, I'd keep an eye on it. I've had mixed experiences myself—sometimes they hold up surprisingly well, other times they're just a temporary band-aid. Had one under my bathroom sink that seemed fine at first, but after a couple months, the leak was back with a vengeance. Turned out the pipe itself had some corrosion issues, and the sealant was just masking the real problem.
Not saying yours will fail, but if you've had that leak bugging you for ages, might be worth double-checking the pipes underneath to make sure there's no bigger issue lurking. Better safe than sorry, especially when it comes to water damage...trust me, learned that one the hard way.
Had a similar issue myself last year—thought I'd nailed it with sealant, but a few weeks later noticed dampness again. Turned out the leak was actually higher up in the pipe, hidden behind the cabinet wall. Ended up having to replace a section of pipe entirely, which wasn't cheap but definitely solved it long-term. Curious if anyone's tried those flexible pipe couplings instead of sealants? Seen them at the store but haven't dared to test one myself yet...
Yeah, sealants can be pretty hit-or-miss in my experience. They're decent for temporary fixes, but long-term they usually let you down—especially if there's any movement or vibration in the pipes. Those flexible couplings you're talking about, though, I've actually used them a handful of times. They're surprisingly reliable if installed correctly. Just make sure you get a snug fit and tighten the clamps evenly—uneven tightening is usually the culprit behind leaks when using those things. Had one under my laundry sink that's held up going on three years now, even with regular heavy use. One downside: they're not exactly the prettiest solution, so if aesthetics matter (like exposed plumbing), you might wanna consider something else. Otherwise, they're a solid option for quick repairs without breaking out the torch and solder.
