You know how frustrating it can be when something’s wrong with your plumbing, but you can’t figure out what? Catching these sneaky hidden leaks early is essential for your health and wallet.

Want to know if you might have a leak somewhere under your floor? Here are eight telltale signs to detect a water leak.

Eight Signs of an Underground Pipe Leak

Check the Water Meter

Here’s a quick test you can do right now: turn off all your water. I mean everything, from faucets to appliances. Take a peek at your water meter reading, then wait an hour and recheck it. If that number’s changed without you using any water, I hate to break it to you, but you’ve probably got a leak. The bigger the change, the bigger the leak!

Decrease in Water Pressure

Ever stepped into the shower and thought, “Huh, the pressure feels a bit weak today”? That could be your pipes trying to tell you something. When water’s escaping from a pipe before it reaches your faucet or shower, you’ll notice that drop in pressure. Even if it’s just a small change, don’t ignore it. These things tend to get worse over time.

High Water Bills

Notice your water usage creeping up even though your habits haven’t changed? Yeah, that’s often a sign of hidden water leaks. You might be paying for water that’s literally going down the drain through a leak. Time to get that checked out before it really starts hitting your wallet!

You Hear Running Water or Similar Sounds

You know that eerie feeling when you’re sitting quietly and hear the sound of running water, but everything’s turned off? Those hissing, dripping, or spraying sounds aren’t just your imagination; they’re often your first clue that something’s up with your pipes.

Foul-Smelling Odors

If you’re catching whiffs of mold, mildew, or (yikes) sewage, something’s definitely not right. Especially with sewer line leaks, your nose often knows before anything else shows up. Don’t try to mask these smells; they’re trying to warn you about potential health risks.

Sudden Floor Stains

Spotted some water damage on your floor lately? Maybe your hardwood’s starting to warp, or those tiles are cracking for no apparent reason? Water has a way of leaving its mark, especially when it’s sneaking out of pipes under your floor. The sooner you address these signs, the better chance you have of avoiding major damage.

Lawn Flooding

If parts of your lawn are suddenly looking like a mini swamp (especially when it hasn’t rained), that’s your cue to investigate. Those soggy spots could mean water’s leaking underground. And if you see anything that looks like sewage, you definitely want to get a pro out there ASAP.

Foundation Cracks

Leaks can mess with your home’s foundation. When water keeps seeping into the soil around your foundation, it can weaken it and cause cracks. See any suspicious cracks in your walls or floors? Don’t wait around on this one. This can also be a sign of a slab leak.
