Leaks at the connections are definitely trickier in my experience. Drips from the box are usually obvious, but a slow leak at a fitting can go unnoticed for ages and cause way more damage behind the scenes. I’ve seen entire baseboards rotted out before anyone realized there was an issue. On sealing, I’m with you—pipe dope on old threads is a lifesaver, but it’s easy to overdo it. I’ve had to clean up more than one mess from someone getting carried away with the stuff... And yeah, nothing beats just watching those joints after you turn the water back on. Fancy alarms are nice, but your eyes and a flashlight catch most problems early.
Honestly, I’ve seen the same thing—slow leaks at a fitting are sneaky and way more destructive over time. You’re right about pipe dope, too. It works, but man, I’ve had to chip away dried gobs from threads because someone went overboard. Less is usually more there. And yeah, high-tech leak detectors sound great, but I still trust just checking with a flashlight after turning the water back on. Caught a tiny drip once that could’ve ruined the whole wall if I’d missed it. Seems like the basics—look, listen, feel—still work best most of the time. Good call on not getting lazy and just assuming everything’s fine after a fix.
Drips from the box vs. leaks at the connections—what’s worse?
I’ve lost count of how many times a “just a drip” at a connection turned into a nightmare behind finished walls. There was this one laundry room job—brand new, everything looked perfect. A week later, the homeowner calls about a musty smell. Pulled off the baseboard and… yeah, slow drip from a fitting had been running down the stud, soaking insulation. Had to cut out a chunk of drywall and replace it all. The worst part? It didn’t even leave a visible puddle, just crept along for days.
Drips from the box can be obvious, especially if you get that telltale puddle or staining. At least then you know where to start. With connections, like you said, it’s sneaky. Sometimes you only catch it by touch—run your finger under each joint, or wrap a bit of tissue around the fitting and see if it gets damp after the water’s back on. High-tech detectors have their place, but nothing beats a flashlight and some patience.
Funny thing about pipe dope—I’ve seen fittings so gunked up you’d think someone was icing a cake. Too much and you’re just making a mess for the next poor soul who has to take it apart. I’m a fan of just enough to coat the threads, maybe a wrap or two of Teflon if I’m feeling cautious.
I get the appeal of trusting new tech, but the old habits really do save headaches. Listen for drips, feel for moisture, look for anything off. I’ve even caught leaks just by noticing a faint discoloration on the copper—tiny mineral tracks showing water’s been there.
In my book, connection leaks are worse simply because they hide so well and can do more damage before anyone notices. At least with a box drip, you usually catch it faster. Either way, a little extra time double-checking saves a lot of hassle down the road.
Totally agree—those hidden connection leaks are brutal. I actually had a tiny one behind my kitchen sink that took months to notice. By the time I caught it, the cabinet bottom was warped and moldy. Felt like such a rookie mistake, but it really is so easy to miss. Honestly, I’d rather deal with a box drip any day... at least you see the mess right away and it doesn’t wreck half your wall. I do wish there was a budget-friendly detector for those sneaky spots, though.

Same here. Those little leaks are like ninjas—by the time you spot them, it’s already a mess. I tried one of those cheap moisture alarms under my bathroom sink, but it only worked after there was already a small puddle. Kinda feels like you need a whole network of them, which adds up. Makes me wonder if there’s an easy DIY trick to catch dampness earlier... maybe even something as simple as checking for that musty smell more often.
