How To Find A Water Leak: 8 Ways To Detect

Don’t Ignore Hidden Leaks

If you suspect a water leak in your home, acting fast is key. Unnoticed leaks can cause structural damage, mold growth, and soaring water bills. The good news? There are simple ways to detect leaks before they spiral into bigger issues.

1. Check Your Water Meter

Turn off all water in the home and watch your water meter. If it continues moving, you likely have a hidden leak. According to the EPA’s Fix a Leak Week, U.S. households waste nearly 1 trillion gallons of water each year due to leaks.

2. Inspect Common Fixtures

Check faucets, toilets, and showerheads for drips. Even a slow drip can waste hundreds of gallons annually. If ignored, it can also contribute to water damage in surrounding areas.

3. Use a Toilet Dye Test

Add a few drops of food coloring into your toilet tank. If color appears in the bowl within 10 minutes, you likely need toilet repair.

4. Listen for Hidden Leaks

Strange hissing or dripping sounds behind walls may point to pipe leaks. If this happens during rainy months, you may also face clogged drains — see our rainy season guide.

5. Inspect Outdoor Irrigation

Leaks in sprinkler systems are common, especially during summer. A spike in your water bill may be the only clue.

6. Look for Mold or Musty Odors

Mold growth often accompanies hidden leaks. If you smell dampness, it’s time to call for professional leak detection.

7. Monitor Your Water Bill

Unexplained spikes in your bill are one of the easiest ways to spot an issue. Compare usage over several months to find anomalies.

8. Schedule a Professional Inspection

If DIY checks aren’t enough, professionals can detect slab leaks, pinhole leaks, and underground issues using advanced tools. Pair inspections with maintenance plans for long-term protection.
