Thermal cameras are handy for a lot of things, but honestly, they’re not great for finding vent leaks unless there’s a big temp difference or moisture involved. I’ve tried it—mostly just see cold spots if there’s air movement, but it’s hit or miss. Usually end up sniffing around like a bloodhound and poking holes in drywall anyway. Sometimes the old nose is still the best tool... even if you wish it wasn’t.
Yeah, thermal cams are cool for a lot of stuff, but tracking down sewer gas isn’t really their strong suit. I’ve had better luck with smoke pencils or even just running water and listening for gurgles. Sometimes, nothing beats crawling around with a flashlight and your nose... as much as I wish that wasn’t true.

Ain’t that the truth. I once spent a Saturday morning wedged behind my water heater, convinced I’d find some high-tech solution, but in the end, it was just me, a cheap headlamp, and a lot of sniffing. The “rotten eggs” smell turned out to be a dried-out floor drain. All the gadgets in the world can’t replace a good old-fashioned nose test... though my wife still laughs about how dramatic I made it sound.
I’ve lost count of how many times I’ve had to rely on my own nose instead of some fancy moisture meter or air quality gadget. Last winter, one of my tenants called about a “dead animal” smell in the basement. I brought every tool I could think of, but it still came down to crawling around, sniffing corners, and following my gut. Ended up being a dried-out P-trap under the utility sink—just needed a jug of water poured down there.
Funny how often it’s the simplest fix. Folks want to believe there’s a high-tech answer for everything, but honestly, most of these “rotten egg” cases are just neglected drains or old traps. Not saying gadgets are useless—they have their place—but sometimes you just have to get your hands dirty (literally) and trust your senses. And yeah, you’ll probably get weird looks from family when you’re crawling around on your hands and knees... part of the territory, I guess.
You nailed it—sometimes the most reliable “tool” is just paying attention to your senses and not overcomplicating things. I’ve run into similar situations where people want to throw technology at every problem, but a lot of these household issues are just about basic maintenance. Dried-out P-traps are classic for that sulfur smell. I’ve even had neighbors convinced they had a gas leak, only to find out it was just a floor drain that hadn’t seen water in months.
I get the appeal of gadgets, especially when you’re trying to be proactive or track down something elusive. But honestly, a moisture meter isn’t going to tell you much about a stinky drain. Sometimes you just have to get down there and investigate. It’s not glamorous, but it works.
One thing I’d add—if you’re trying to keep things eco-friendly, regular checks on unused drains can save you from having to use harsh chemicals later. Just running a bit of water through every so often keeps those traps sealed and the air clean. It’s simple, but it makes a difference.
And yeah, crawling around on the floor isn’t exactly dignified, but it beats ignoring the problem until it gets worse. I’ve definitely gotten some odd looks from my partner when I’m sniffing around the laundry room, but hey, better that than letting a small issue turn into a big one.
It’s easy to forget how much of home maintenance is just about being observant and not assuming the worst. High-tech solutions have their place, but sometimes you just need to trust your instincts—and your nose.
