Home plumbing checkups: DIY checklist or pro inspection?

Honestly, I never even thought to take pics behind the washer until now - genius move. I swear, every time I try to slide that thing out, it feels like a full-body workout and then I just want to shove it back and forget what I saw. But yeah, those little leaks are sneaky. I found a weird rusty ring under my water heater last year and freaked out, but turns out it was just from an old can of paint someone left there. Still, better safe than sorry.

I’m all for tackling the easy stuff myself, but once pipes start making noises like they’re haunted or the water’s looking funky, I’m out. No shame in waving the white flag and calling a pro. Sometimes you just need someone who actually knows what they’re looking at... instead of me googling “why does my pipe sound like a dying whale.”

Dragging the washer out is basically my cardio for the month, so I get it. Taking pics is a game-changer though - makes it way easier to remember what’s going on back there. I totally agree about calling in the pros when things get weird, but I do think a quick monthly check (look for drips, check under sinks, feel for dampness) saves a lot of headaches. Pipes making “whale” noises? Usually air in the lines or loose washers, but yeah, sometimes you just gotta let the experts handle it.

Totally agree on the photos. I used to scribble notes, but a couple quick phone pics save so much time when you’re hunting for that one weird valve later. Here’s what I’d add:

- Don’t just check under sinks - run your hand along the supply lines too. Sometimes leaks start small and you’ll feel that dampness before you see it.
- Listen for any gurgling or slow drains. That’s usually a sign you’ve got a clog starting somewhere.
- If you’re moving appliances, peek at the hoses. Any bulges or cracks? Just swap them out. Learned that the hard way after a laundry room flood...
- Monthly is good, but if you’ve got older pipes, maybe check a little more often. Stuff sneaks up fast.

I’m with you on calling the pros for anything sketchy or beyond basic fixes. No shame in knowing your limits.

Not sure I agree on checking things monthly, especially if you’ve got a newer place.

Monthly is good, but if you’ve got older pipes, maybe check a little more often.

I get where you’re coming from - monthly checks can feel like a lot, especially in newer places. Here’s how I usually handle it across my properties:

- Newer builds: I just do a quick look-over every season, unless there’s a weird smell or water pressure drops.
- Older homes: I’ll peek under sinks and around the water heater every month or two, just because small leaks can get expensive fast.
- If tenants mention anything, I jump on it right away.

Honestly, I’ve caught a couple of slow leaks early this way, but I don’t think you need to go overboard unless you’ve had issues before. Seasonally works for most folks, in my experience.

I don’t think you need to go overboard unless you’ve had issues before. Seasonally works for most folks, in my experience.

I get the logic, but honestly, I’ve seen too many “minor” leaks turn into big headaches because folks waited for a seasonal check. Especially in older houses - sometimes those slow drips under a sink don’t show up until there’s already water damage in the cabinet or, worse, mold. I’m not saying monthly is always necessary, but I do a quick check every time I’m at a property, even if it’s just to swap out furnace filters or whatever.

Also, DIY is fine for the basics, but every couple years I’ll bring in a plumber just to do a pressure test and look at the stuff I can’t see. Caught a pinhole leak in a copper line that way once - would’ve been a mess if I’d waited for “signs.” Guess it depends on your risk tolerance and how much you like surprises...

- I get the urge to check everything, but I’m all about balance (and saving a buck).
- My DIY list: peek under sinks, feel around toilets, check the basement for puddles, and eyeball the water meter every now and then.
- If something smells funky or I see a drip, then yeah, I’ll call in a pro. Otherwise, I’d rather spend the plumber money on pizza... or, you know, actual emergencies.
- Old house here too - once found a slow leak behind the washing machine just by following my nose. Not glamorous, but it worked.

I get the “save a buck” approach, but I’ve had a couple rentals where a slow leak turned into a way bigger problem than I expected.

“If something smells funky or I see a drip, then yeah, I’ll call in a pro.”

Had a place once where the only clue was a slightly warped baseboard - turned out water had been dripping behind the wall for months. DIY checks are great for the obvious stuff, but older homes? I usually bite the bullet and get a pro in every couple years. Peace of mind’s worth it, especially after that mess.

DIY checks are great for the obvious stuff, but older homes? I usually bite the bullet and get a pro in every couple years.

I get the peace of mind angle, but honestly, most of the time I’ve found pros just do the same surface checks I do - except they charge a lot more. If you know what to look for (like stains under sinks, weird smells, water pressure changes), you can catch most issues before they get out of hand. Plus, you learn your house inside out. Sure, some things need a pro, but every couple years feels like overkill unless you’re seeing real warning signs.

I totally get where you’re coming from. Honestly, I’ve seen plenty of “professional” inspections that just check the same boxes any detail-oriented homeowner could. If you’re comfortable poking around and know what to watch for - like those subtle stains or even a faint musty odor - you’re already ahead of the game. I’m a big fan of learning the quirks of your own place, too. Unless you’re dealing with really old pipes or have a history of issues, calling in a pro every couple years does seem a bit much.

Home Plumbing Checkups: DIY Checklist Or Pro Inspection?

Yeah, I’m with you - most of the time, a careful walk-through does the trick. I always start under sinks for drips, then check around toilets and tubs for soft spots or discoloration. Don’t forget to run every faucet and flush every toilet, just to see if anything’s slow or noisy. If you’ve got a basement, look at the exposed pipes for corrosion or weird bulges. Unless you’re seeing rust, green stains, or hearing banging in the walls, you’re probably fine handling it yourself. Only time I call in a pro is if I spot something I can’t explain or if the house is ancient... those old galvanized pipes can hide some nasty surprises.

Those old pipes really can be a headache... I had a slow leak behind a wall for months before I noticed the paint bubbling. Ever tried using one of those moisture meters, or do you just rely on visual checks?

I hear you on the old pipes - sometimes it feels like you’re just waiting for the next surprise. I’ve actually started using a moisture meter after missing a leak behind some drywall a few years back. Visual checks are good, but those meters can catch stuff you’d never spot until it’s too late. Have you tried using an infrared camera? They’re a bit pricier, but they pick up temperature differences from hidden leaks. Just curious if anyone else has found them worth it, or if it’s overkill for most homes...

Have you tried using an infrared camera? They’re a bit pricier, but they pick up temperature differences from hidden leaks.

I’ve wondered about those too. My place is almost a hundred years old, so I’m always half-expecting to find a surprise leak somewhere. I’ve stuck with moisture meters and the occasional pro inspection, mostly because I’m not sure if an infrared camera would really catch much more in these thick plaster walls. Has anyone actually found a hidden leak with one, or is it mostly peace of mind? Sometimes I feel like the old-school methods work just fine, but maybe I’m missing out...

I know what you mean about those old houses - mine’s from the 1920s and there’s always some mystery behind the walls. I’ve used an infrared camera a couple times, but honestly, it’s been hit or miss.

I’m not sure if an infrared camera would really catch much more in these thick plaster walls.

That’s been my experience too. If you’ve got lath and plaster, sometimes the camera just picks up weird heat signatures that don’t tell you much. I did catch a small leak once behind drywall, but with plaster, it’s tougher. Moisture meters seem to give more reliable info in those situations.

I still lean on pros for the big inspections, especially before buying or selling. For regular checkups, I just keep an eye out for stains or soft spots and use the meter if something seems off. The tech is cool, but sometimes it feels like overkill unless you’re dealing with newer construction or have a real reason to suspect a hidden problem.

I get where you’re coming from, but I wouldn’t write off the tech just yet, even with old plaster. I’ve seen IR cameras pick up subtle temp differences around old radiator pipes or spots where insulation’s been compromised - sometimes that’s your first clue before you ever see a stain. Sure, it’s not always crystal clear, and yeah, lath and plaster can throw off weird readings, but paired with a moisture meter and a little know-how, you can get a pretty good sense of what’s happening behind the scenes.

Honestly, I think people underestimate how much damage a slow leak can do before it ever shows up as a stain. Waiting for a soft spot or visible sign is rolling the dice a bit. I’d rather spend a few minutes with some tools than risk tearing out a wall down the road. Not saying everyone needs to buy a $500 camera, but borrowing or renting one every couple years isn’t the worst idea, especially in these old houses that love to hide problems.

Had a flashback to the time I bought my first fixer-upper and thought, “Eh, I’ll just wait for a stain to show up.” Fast forward a few months, and I’m peeling back wallpaper only to find a patch of wall that looked like it’d been through a swamp. IR camera probably would’ve saved me a weekend of drywall dust in my hair. I get the skepticism, but those gadgets can be a lifesaver - especially if you’re dealing with 100-year-old plumbing that’s seen better days. I still do the old “knock and sniff” test, but I trust the tech a bit more now.

That “knock and sniff” test cracks me up - honestly, it’s still my go-to for old houses, too. But yeah, there’s only so much your nose can tell you before you end up knee-deep in mystery gunk. I’m always torn between trusting my instincts and leaning on the gadgets. IR cameras are great, but I’ve seen them throw false positives if the sun’s been hitting a wall weirdly, or if there’s just a draft.

Curious - did you ever try one of those moisture meters? I’ve found them surprisingly helpful, though they make me feel like I’m playing Ghostbusters. Still, nothing beats actually opening up a wall... except when it’s full of ancient, terrifying pipes and questionable insulation. Sometimes I wonder if it’s worth just calling in a pro for the peace of mind, but then again, where’s the fun in that?

Do you think there’s a sweet spot between tech and old-school detective work? Or is it just a matter of how much drywall dust you’re willing to live with?

Title: Home plumbing checkups: DIY checklist or pro inspection?

I hear you on the IR cameras - had one tell me there was a “leak” in a wall that turned out to be nothing but a cold draft from a busted window seal. Moisture meters are handy, but I’ve had them freak out over condensation from a humidifier, too. Honestly, I trust my gut first, then use the gadgets to double-check if something feels off.

Opening up a wall is always a gamble. Last time I did it, I found a squirrel’s stash of acorns and what looked like 1950s insulation made out of old newspapers. Not exactly what I was hoping for, but at least I got to the root of the musty smell.

I think there’s a balance. I’ll use tech for the first pass, but if I’m still suspicious, I’ll cut a small inspection hole. Drywall dust is annoying, but it beats missing a slow leak that turns into a nightmare later. I only call in a pro if I hit something I can’t identify or if it’s a main line issue - otherwise, I’d rather know exactly what’s going on behind the scenes.

Curious - how do you handle those borderline cases where you’re not sure if it’s worth tearing into the wall? Ever regret not just biting the bullet and opening it up sooner?
