Honestly, I’m with you on the “cheap insurance” thing. Those little alarms are lifesavers—mine went off at 2am once and saved me from a soggy mess. Still, I’d add that sometimes tightening stuff can make things worse if you’re not careful. Over-tighten a plastic trap and you’ll crack it, then you’re in for a real headache.
If it’s still leaking or if you see corrosion/pinhole leaks... don’t mess around—shut off the water and call in backup.
Couldn’t agree more. I tried patching a pinhole with tape once (don’t ask), and it held for about a day before turning into a tiny fountain. Lesson learned: if you see green crust or rust, it’s probably time to call someone who knows what they’re doing.
One thing I’d add—if you’re poking around under there, make sure you know where the shutoff valves are and that they actually work. Found out the hard way mine were stuck open... not fun when water’s spraying everywhere. Sometimes the “quick fix” is just knowing how to stop the flood before it starts.
Totally get the “quick fix” urge, but yeah, those rarely hold up. I’ve also tried the tape trick on a copper line—lasted about as long as it took for me to find a bucket.

Can’t argue with that. Once you see corrosion, it’s usually a sign there’s more going on than just a loose fitting. Sometimes I wonder if people underestimate how fast water damage can get out of hand—one tiny leak and suddenly you’re dealing with warped cabinets or worse.
As for shutoff valves, I’m always surprised how many folks don’t realize theirs are seized until it’s too late. I try to turn mine off and back on every few months just to keep them from freezing up. Not saying everyone needs to be obsessive about it, but it beats scrambling around in a panic when something bursts.
One thing I’d add: even if you’re confident DIY-ing, have a plan B (and maybe C) ready... because plumbing projects love to surprise you.
I’ve lost count of how many times I’ve walked into a unit and found a “temporary” fix that’s been there for years—duct tape, plastic bags, you name it. Folks really do underestimate how fast water can wreck a place. I always tell my tenants: if you see green or crusty stuff, don’t mess around. That’s not just a drip, it’s a warning sign. And yeah, seized shutoff valves are the silent killers. I make it a point to check them every turnover, but honestly, most people never touch them until it’s too late. DIY is fine for some things, but with plumbing, the margin for error is tiny and the consequences are expensive.
I hear you on the “temporary” fixes—my last place had a leak “fixed” with a bread bag twist tie. I’m always torn between trying to DIY and just calling in a pro, especially when it comes to shutoff valves. Is there a safe way to test if they’re seized without making things worse? I’d rather not find out the hard way, but I also don’t want to pay for something simple if I can help it.
Yeah, I totally get the hesitation. I’ve had shutoff valves that felt like they were welded in place, and I was scared to force them. What I usually do is gently try to turn them with a towel for grip—if they don’t budge with light pressure, I stop. Last thing I want is to snap something and end up with a geyser under the sink. Sometimes a little WD-40 helps, but honestly, if it feels stuck, I’d rather pay a pro than risk a flood. It’s annoying, but cheaper than water damage in the long run.
