You’re not wrong—sometimes your nose and ears pick up on stuff that a camera just can’t. I’ve had a sewer line camera miss a pinhole leak before, and it was only the faint smell that tipped me off. That said, I do like to use both my senses and tools if I can. If you’re already getting musty odors or weird noises, especially with old pipes, there’s probably something brewing behind the walls or under the floor.
I’d say you’re on the right track with opening things up if you have a strong hunch. Water damage is a nightmare to fix after the fact, and it’s usually way more expensive than just swapping out some pipe sections ahead of time. I’ve done “exploratory surgery” on my own place more than once—cutting open drywall just to check—and yeah, sometimes it feels like overkill, but when you find corrosion or buildup, it’s worth it.
One thing I’d add: if you’re dealing with galvanized steel or even old copper, they can look okay from the outside but be totally shot inside. A little section cut out will tell you a lot. And if you see any greenish or white crust on joints, that’s another red flag.
Not everyone wants to go tearing into their walls at the first sign of trouble, but in my experience, trusting your gut saves headaches down the line. Better to patch some drywall now than mop up a flood later...
I get where you’re coming from, but I’ve seen folks tear into walls chasing a smell or a noise, only to find nothing but dust and old insulation. Sometimes it’s just a funky drain or a loose fitting making noise. I’m not saying ignore your gut, but I’d rather start with moisture meters or thermal cameras before grabbing the drywall saw. Had a client once who ripped out half his basement ceiling for what turned out to be a dried-up P-trap. Sometimes patience (and a few extra tests) saves you from unnecessary patchwork.
I get the caution, but isn’t there a risk in waiting too long to open things up? I’ve seen slow leaks go undetected for ages because folks relied on gadgets or just hoped it was nothing. Sometimes you gotta trust your nose and just peek behind the wall, especially with really old pipes. Ever had a moisture meter miss something obvious?

That’s a good point. I’ve definitely seen moisture meters miss slow leaks, especially in older homes where the readings can be thrown off by insulation or even just thick paint. Technology helps, but nothing beats a bit of old-fashioned suspicion when something feels off. If you’re smelling that musty odor or seeing even a faint stain, it’s usually worth a closer look. Sometimes waiting for “proof” from gadgets just lets the problem get worse. Trust your instincts—pipes don’t last forever, and catching issues early saves a ton of hassle down the line.
Yeah, I totally get what you’re saying. Relying on gadgets alone can be a bit of a trap, especially with older plumbing. I’ve found that sometimes even the tiniest whiff of mildew is your best clue, no matter what the meter says. And honestly, replacing pipes before they become a disaster is way more eco-friendly than dealing with water damage and mold remediation later. Trust those instincts—you’re probably saving yourself a bigger headache and a lot more waste in the long run.
