- Good instincts sticking with the pin meters for accuracy, but honestly, every tool has its moment.
- Pinless meters have saved me from putting holes in a client’s new trim more than once—sometimes you just need to get a sense of what’s going on without making things worse.
- That hissing sound is tricky. I’ve chased down “leaks” before that turned out to be nothing but HVAC drafts sneaking through gaps. Trust your gut, but don’t stress too much if you’re not seeing obvious water damage.
- Keep at it—sometimes it’s just about ruling things out one by one.
That’s a good point about pinless meters—never thought I’d care about tiny holes until I had to patch a dozen of them after chasing a “leak” that turned out to be nothing. I get what you mean in the quote here:

I’m still skeptical, though. How do you actually tell the difference between a draft and a real leak if you can’t see any water stains? I’ve stuck my ear to the wall, waved a tissue around for drafts, but it’s always a guessing game. Anyone ever found something totally unexpected when tracking down a sound like this?
That weird hissing sound behind the bathroom door...
I get where you’re coming from—sometimes it really is just a draft, and it’s easy to overthink every little noise. But I’d be careful about assuming it’s “nothing” just because you don’t see water stains. Not every leak leaves a visible mark right away, especially if it’s a slow one or if the water’s running down inside the wall cavity. I’ve seen cases where the only clue was a faint hiss, and by the time stains showed up, there was already mold behind the drywall.
The tissue test is a good start for drafts, but it’s not foolproof. Air currents can be sneaky, and sometimes HVAC returns or even plumbing vent stacks can make odd noises that sound like leaks. One thing I’ve found helpful is using an infrared thermometer to check for cold spots along the wall or floor—if there’s a leak, you’ll often see a cooler area where water’s evaporating. It’s not perfect, but it can help narrow things down without making holes everywhere.
There was one time I thought I was chasing a pipe leak because of a persistent hiss in a bathroom wall. Turned out, it was a cracked toilet fill valve making noise that echoed through the plumbing chase. No water damage, just a cheap part vibrating at the right frequency to drive me nuts for a week.
I’d say, don’t rule out a leak just because you can’t see it, but don’t go tearing into walls without a bit more evidence either. Sometimes it’s worth shutting off the water supply for a few hours and seeing if the sound stops. If it does, you’ve probably got a plumbing issue. If not, maybe it’s just air moving around or something mechanical. Either way, patience and a methodical approach usually save a lot of patching later on.
Yeah, I’m with you—never hurts to be cautious. That hissing sound can be a real pain to track down. I’ve seen folks chase “leaks” for days only to realize it was a loose washer vibrating or even just water running through pipes in the wall from another room. One trick I use is to check the water meter before and after a couple hours of no usage—if it moves at all, something’s leaking somewhere. Not super high-tech, but it’s saved me from opening up drywall more than once. Sometimes it’s just the house settling or HVAC doing weird things, but you never really know until you dig a little deeper.

That’s a classic move, and honestly, it’s saved me from tearing up more than a few floors. Sometimes it’s just a sneaky toilet flapper, though—those things can hiss like a snake in the grass and drive you nuts. I’ve even had tenants swear there’s a leak, only to find out it’s the neighbor’s shower on the other side of the wall. The joys of plumbing...
