Quick fixes for surprise water disasters - does pipe tape actually work?

Used that silicone tape plenty of times for quick fixes - honestly, it’s just a stopgap. I’ve seen it hold for a week, maybe two, but it always ends up leaking again. Did you check if the pipe’s actually cracked or just a loose fitting? That makes a difference. I wouldn’t trust tape for anything long-term under a sink, especially if it’s pressurized.

I get where you’re coming from, but I’ve actually had better luck with that silicone tape than I care to admit. Had a tenant call me at 2am once - water everywhere, panic mode. Slapped some tape on a pinhole in a copper line, and it held for almost a month before I could get a plumber in. Not saying it’s a miracle cure, but sometimes you just need something to buy you time (and sleep). Wouldn’t trust it forever, but for emergencies? It’s saved my bacon more than once.

I've seen that tape hold up in a pinch too, but I always wonder how much pressure those quick fixes can really handle. Did you notice any leak at all during that month, or was it bone dry the whole time? Sometimes I find the tape starts to weep after a few days, especially if the pipe isn’t perfectly clean or dry when you wrap it. Curious how consistent your results have been.

Honestly, that’s what worries me too - the tape seems to work at first, but I’ve had it start to seep after a couple days, especially if the pipe is even a little damp when you put it on. I get tempted to just leave it, but I can’t shake the feeling it’s just delaying the inevitable. For anything more than a tiny drip, I’d rather shut off the water and deal with the hassle than risk a bigger mess later. Maybe I’m just paranoid, but water damage is no joke.
