Sneaky signs your home might be hiding water trouble

"A friend tipped me off to using a flashlight at an angle on walls and ceilings to spot shadows from swelling drywall or paint. Pretty handy trick, actually."

That's a solid tip - I've used that flashlight trick myself more times than I'd like to admit. Another sneaky one I've noticed is keeping an eye on your water meter. If you suspect something's up, turn off all your faucets and appliances, then check the meter. Wait 20-30 minutes and see if it's moved at all. Even a tiny leak can cause it to tick forward slightly.

Also, pay attention to your pets - they're surprisingly good leak detectors. My dog kept sniffing around the dishwasher once, and sure enough, there was a slow drip behind it. Saved me from a bigger headache later.

And speaking of smells...musty odors are definitely a red flag, but sometimes leaks give off weirdly sweet or earthy scents too (sounds odd, I know). Bottom line: trust your nose as much as your eyes.

The water-meter check is useful, but I’d add a longer-term comparison: check the current water bill against the same season last year. Seasonal use can vary, but a steady unexplained increase can be an early clue to a running toilet, supply-line leak, or under-slab leak. It’s especially worth checking if you suspect something intermittent that doesn’t show up during a 20-minute meter test.

The longer-term bill comparison is useful, especially for intermittent leaks. One caveat with the 20–30 minute meter test: make sure irrigation, a water softener, ice maker, or other automatic system isn’t scheduled to run during it. Disable those cycles first, or account for them, or the meter movement can point you in the wrong direction.
