Home plumbing checkups: DIY checklist or pro inspection?

Water always wins if you let your guard down.

Ain’t that the truth. I used to think a quick peek under the sink was enough - until I found a “mystery puddle” in the basement. Now my routine includes sniff tests for musty smells and running my hand along pipes for damp spots. Still, I agree, nothing beats a pro’s infrared camera for finding the stuff you can’t see. Worth the peace of mind, especially in these old houses that seem to hide leaks like it’s a game.

I hear you on the “mystery puddle” - old houses are notorious for that sort of thing. My go-to is a checklist I’ve put together over the years: check under sinks, around toilets, behind appliances, and don’t forget the ceilings for any stains. I try to get into crawl spaces every few months, too. Still, you’re right, infrared cameras catch what we can’t. For me, a combo of routine DIY checks and a pro inspection every couple years seems to catch most issues before they get expensive.

Title: Home Plumbing Checkups: DIY Checklist or Pro Inspection?

For me, a combo of routine DIY checks and a pro inspection every couple years seems to catch most issues before they get expensive.

Not to rain on the parade, but I've seen plenty of situations where those “every couple years” pro inspections missed stuff that turned ugly fast. Water lines, especially old galvanized or copper, can spring pinhole leaks you won’t spot until the drywall’s stained or the subfloor’s mushy. Even the best DIY checklist can’t always catch things like slow leaks inside walls or under slab foundations.

If you’re living in an older place, honestly, I’d nudge the pro inspection up to once a year, especially if you’ve got any history of leaks or recent plumbing work. Had a client swear by their checklist and still ended up with a $5k repair because a wax ring failed behind a rarely-used toilet. Infrared cameras are great, but they’re not a magic bullet - sometimes it’s the old-school moisture meter or even just a seasoned plumber’s nose that catches the musty smell before the rot sets in.

Routine checks are great, but with plumbing, I’d err on the side of too careful. Water damage is sneaky and expensive.

Infrared cameras are great, but they’re not a magic bullet - sometimes it’s the old-school moisture meter or even just a seasoned plumber’s nose that catches the musty smell before the rot sets in.

That’s the truth. I once bought a duplex where the “pro” inspector gave it a clean bill of health, but a week after closing, I noticed the faintest whiff of Eau de Swamp in the hallway. Turns out, a slow leak had been marinating the subfloor for months. Ended up with a plumber crawling around like a truffle pig, sniffing out the source. Cost me a chunk, but at least I got a good story out of it.

I get the urge to save a few bucks with DIY, but water’s like that one tenant who never calls until the ceiling’s caving in. Curious - has anyone actually found a leak with one of those fancy cameras, or is it mostly just plumbers using their “spidey senses”? I’m starting to think the best tool is paranoia...

Paranoia’s not a bad tool, honestly. I’ve used infrared cameras plenty, and they’re great for spotting temperature differences, but they miss stuff if the leak’s not active or the area’s already dried out. Sometimes it’s just a weird stain on the baseboard or a soft spot in the floor that gives it away. I trust my moisture meter more than any camera, but nothing beats poking around and trusting your gut when something smells off. Technology’s helpful, but it’s not a substitute for actually getting your hands dirty.

Totally get what you mean - sometimes my old house just “feels” off and that’s when I know to start poking around. I’ve had leaks hide out for ages, right under my nose. Fancy gadgets are cool, but nothing beats a suspicious nose and a screwdriver.

Fancy gadgets are cool, but nothing beats a suspicious nose and a screwdriver.

That’s the truth. I once found a slow drip behind my washing machine just because I caught a faint musty smell - turns out the drywall was soaked. I’ve tried those moisture meters, but honestly, my nose and a flashlight have caught more issues than any gadget. Still, I’ll admit, I call in a pro every few years just to double-check the stuff I can’t see. Old pipes have a way of hiding their secrets...

I hear you on the “old pipes hiding secrets” part. I once bought a duplex where everything looked fine - until I noticed the kitchen sink draining slower than my patience during tax season. Ended up snaking out a wad of ancient potato peels and, weirdly, a Barbie shoe. Gadgets are fun, but nothing beats getting your hands dirty (and sometimes questioning your life choices). Still, I’ll spring for a pro when it comes to crawl spaces... those things are basically haunted.

- Had a similar “what is THAT?” moment pulling a plastic dinosaur out of a bathroom drain.
- I’ll check visible pipes and under sinks, but when it comes to anything behind walls or under floors, I’m out.
- Sometimes I wonder if old houses are just testing our patience on purpose...
- DIY is fine for the basics, but I’d rather not risk a surprise indoor waterfall.

- Totally get the “what is THAT?” moment - found a Barbie shoe in a kitchen sink once.
- Checking visible pipes and under sinks is honestly more than most people do, so props for that.
- Old houses really do seem to have a sense of humor... or maybe just a grudge.
- DIY is great for the basics, but I’m with you - anything involving hidden pipes feels like tempting fate.
- Sometimes it’s worth paying for peace of mind, especially if you value your floors (and sanity).

- I get the peace of mind thing, but honestly, I feel like calling a pro every time something’s hidden is overkill.
- Watched a bunch of YouTube vids and managed to fix a leaky pipe behind drywall - just took it slow and double-checked everything.
- Not saying everyone should, but sometimes DIY saves a ton (and you learn stuff).
- Floors are important, but so is not spending $200 for a five-minute fix... right?

Floors are important, but so is not spending $200 for a five-minute fix... right?

Honestly, I get where you’re coming from. I’ve patched up plenty of leaks myself, but sometimes those “five-minute fixes” turn into a weekend project if you miss something small. Ever had a DIY job go sideways and end up costing more in the long run?

- Oh man, last year I tried to “quick-fix” a leaky shutoff valve under the bathroom sink. Figured it’d take me an hour tops.
- Ended up stripping the threads, flooding the cabinet, and - yep - warped the brand new laminate floor.
- That $8 valve turned into $350 worth of repairs. My wallet still cries when I walk past that bathroom.
- Sometimes those “five-minute fixes” are like those bags of chips labeled “family size”… never enough and always gone too fast.

Been there - old houses love to surprise you with “quick fixes” that spiral. Honestly, I think you handled it better than most would’ve. Sometimes, calling in a pro is just the smarter move, especially when water’s involved. Those little leaks can turn into big regrets fast.

I get what you mean - water issues can escalate so fast if you miss something. When you say “pro,” do you mean just for big stuff, or do you have them do regular checkups too? I’ve been sticking to the basic DIY checklist: look for drips, test shutoff valves, check water pressure, that sort of thing. But honestly, I keep second-guessing myself on the stuff behind walls. How do you know when it’s worth bringing someone in, versus just keeping an eye on things yourself?

Honestly, I think the DIY checklist covers more than people give it credit for. Most leaks or pressure issues start small and show up in those basic checks. The stuff behind walls is tricky, but unless you’re seeing signs - like stains, musty smells, or weird spikes in your water bill - I’d hold off on calling a pro every year. I’ve found that being consistent with the basics catches most problems before they get out of hand.

I totally get where you’re coming from. I just started trying to handle more stuff myself around the house, and the DIY checklist felt a bit intimidating at first, but it’s actually helped me catch a couple of things early. Last month, I noticed a tiny drip under the kitchen sink - nothing major, just a little dampness on the cleaning supplies. If I hadn’t been poking around checking for loose pipes (literally just because it was on the list), I probably wouldn’t have caught it until it got much worse.

But I do wonder about those hidden problems. My house is old - like, “has stories to tell” old - and sometimes I worry that something’s happening behind the walls that I can’t see or smell yet. Maybe I’m just being paranoid because I’ve heard horror stories about burst pipes ruining floors overnight. Has anyone actually had a big problem sneak up on them, even when they were doing regular checks? Or is that mostly just bad luck?

I’m leaning toward sticking with the basics for now, but there’s always that little voice in my head saying maybe I should get a pro in once in a while... especially since I'm still learning what normal looks like in a 1950s house. Curious if anyone’s ever regretted not calling someone sooner, or if those checklist items really do catch almost everything before it gets serious.

Honestly, I’ve had the same worry - like, what if there’s a slow leak in the wall and I’m just blissfully unaware until my floor caves in? I do the checklist stuff pretty religiously, but there’s always that nagging “what am I missing?” feeling. One time I skipped calling a pro for a weird noise in the pipes, and it turned out to be nothing... but I spent weeks second-guessing myself. For me, the checklist catches most things, but every couple years I’ll have someone do a quick once-over just for peace of mind (and so I can sleep at night). Worth it for an old house with quirks.

I totally get that nagging feeling - old houses can be full of surprises. I’m still learning as I go, but I’ve found that doing a basic DIY check every few months helps me catch obvious stuff (like leaks under sinks or weird water spots). But honestly, I agree with you about bringing in a pro every now and then. There are just some things I’d never notice, and it’s worth the extra cost for the peace of mind. I guess the trick is finding a balance between obsessing over every little thing and ignoring potential problems.

Honestly, I think you nailed it - balance is everything. I do my own checks too, but there’s stuff like slow drains or weird pipe noises that can sneak up on you. Once, I missed a tiny drip behind a wall and it turned into a whole drywall project... not fun. I keep a running list of things to watch for, but every couple years, I’ll have a plumber do a walkthrough just in case. It’s amazing what they spot that I’d never even think to look for.
