Home plumbing checkups: DIY checklist or pro inspection?

Old pipes are always a gamble, honestly. I’ve chased leaks in my crawl space that didn’t show up on any of my usual checks - no wet drywall, no big drop in pressure. Found out later it was a slow drip behind insulation, only caught it when I had to open the wall for unrelated wiring. Ever thought about using those cheap moisture sensors you can stash near trouble spots? Not as fancy as thermal cameras, but they might help catch something early. Wonder if anyone’s had luck with them on older homes like ours...

I get the appeal of those little moisture sensors - cheap and easy to toss under sinks or near the water heater. Still, I’ve had mixed results with them in my old place. Sometimes they’d go off just from humidity spikes, not actual leaks. The false alarms got annoying, especially in the basement where it’s always a bit damp anyway.

Honestly, I’ve found that nothing really beats a good hands-on check every few months. I’ll poke around, look for corrosion on fittings, feel along pipes for any hint of dampness. It’s not high-tech but it’s caught a couple slow leaks before they turned into a mess. Those sensors might help in spots you can’t easily reach, but I wouldn’t trust them as my only line of defense.

And about thermal cameras - yeah, they’re pricey, but if you can borrow one from a buddy or the local tool library, it’s pretty eye-opening. Found a cold spot behind a wall once that turned out to be a tiny pinhole leak. Would’ve never spotted it otherwise. Just my two cents... sometimes old-school eyeballs work better than gadgets.

I get that. I tried a few cheap sensors under my crawlspace pipes - ended up with more false alarms than real issues. Honestly, I trust a flashlight and some patience more. Still, I’m tempted by those thermal cams, just not sure they’re worth the splurge for me.

I hear you on the false alarms. I grabbed a cheap moisture sensor for under the kitchen sink last year, and it went off every time the humidity spiked - even when there was nothing wrong. Ended up just adding to my stress instead of helping. Honestly, a decent flashlight and a careful look around have caught more issues for me than any gadget so far.

Thermal cameras do sound cool, but unless you’ve got chronic leak mysteries or old pipes everywhere, they might be overkill for most folks. I’ve managed with just a mirror on a stick and a phone camera for tricky spots. Curious if the pricier cameras actually save enough time or hassle to justify the cost... but for now, I’d rather put that money toward something else around the house. Feels like, in most cases, patience and an extra set of eyes wins out.

I get where you’re coming from - some of these “smart” sensors just end up being more trouble than they’re worth, especially the budget ones. I’ve had a few false alarms myself, and it’s always at the worst possible time. I do like the idea of using a thermal camera, but I’ve hesitated for the same reasons you mentioned. The price tag is steep, and unless you’re dealing with a lot of hidden leaks or you’re flipping older properties, it’s hard to justify.

One thing I’ve wondered about: has anyone actually compared the time saved by using a thermal camera versus just doing a thorough manual inspection? Like, if you’re checking multiple units or a big house, does the camera really speed things up, or is it just a cool toy? I’ve seen some pros swear by them, but I can’t tell if that’s just because they already own one.

Also, for those who’ve gone the DIY route, how often do you actually catch something early enough to make a difference? I’m all for regular checkups, but sometimes I wonder if I’m just being paranoid, poking around under sinks every month. Maybe there’s a happy medium - like, a solid checklist and a couple of basic tools, but not going overboard with gadgets.

Curious if anyone’s found a balance that works, especially in older homes where surprises seem to pop up more often. Do you stick to a schedule, or just check things out when you remember?
