Guide to Detecting Hidden Water Leaks

January 31, 2025

Water leaks can be sneaky, often hiding behind walls, under floors, or in your plumbing system until they cause significant damage. Undetected leaks can lead to high water bills, mold growth, and costly repairs. At City Plumbing and Rooter in Arizona, we want to help homeowners catch these leaks early. Here’s how you can detect hidden water leaks before they turn into big problems.

1. Watch for Unexpected Spikes in Your Water Bill

One of the first signs of a hidden leak is a sudden increase in your water bill without an obvious reason. If your usage hasn’t changed but your bill has, it’s time to investigate.

2. Check Your Water Meter

A simple way to detect a leak is by using your water meter:

  • Turn off all water sources in your home.
  • Locate your water meter and take a reading.
  • Wait 30-60 minutes without using any water, then check the meter again.
  • If the numbers have changed, you likely have a leak somewhere in your plumbing.

3. Listen for Unusual Sounds

Do you hear dripping, hissing, or running water when no taps are on? These sounds could indicate a leak within your walls, under the floor, or in your plumbing system.

4. Look for Water Stains or Discoloration

Water stains on ceilings, walls, or floors can signal a hidden leak. Yellowish or brown discoloration, peeling paint, or bubbling wallpaper may be signs of moisture buildup behind the surface.

5. Check for Mold and Musty Smells

Leaks create damp environments perfect for mold growth. If you notice a musty smell or see mold in areas that shouldn't be wet (such as walls, baseboards, or cabinets), you may have a hidden water leak.

6. Monitor Your Water Pressure

A sudden drop in water pressure can indicate a leak in your plumbing system. If your faucets or showerheads aren’t delivering the same strong flow, it’s worth checking for hidden leaks.

7. Inspect Your Yard

If you notice unexplained wet patches, lush green spots, or pooling water in your yard, you may have a leak in your underground water line.
