1. Unexplained Increase in Your Water Bill

 

A sudden spike in your water bill without an increase in usage is one of the first red flags of a hidden water leak. Even a small, slow drip can waste hundreds of gallons of water per month.

 

How to Check:

 

  • Compare your current bill to previous months—if it’s unusually high, a leak may be present.

  • Turn off all water-using appliances and check your water meter—if it’s still moving, there’s likely a leak.

 

Not sure where the leak is? Call our leak detection experts for a professional inspection.

 

 

2. Water Stains on Walls, Ceilings, or Floors

 

Brownish stains, peeling paint, or bubbling wallpaper often indicate hidden leaks.

 

Common causes:

 

  • Leaking pipes inside walls

  • Roof leaks

  • Deteriorated plumbing connections

 

If stains keep growing, the leak is active and needs immediate attention.

 

 

3. Mold and Mildew Growth

 

Musty odors or mold buildup in dry areas like cabinets or under carpets can point to plumbing leaks creating hidden moisture.

 

Watch for leaks:

 

  • Under sinks

  • Behind walls

  • Near water heaters or behind toilets

 

Mold can cause respiratory issues, so act quickly.

 

 

4. Sounds of Running Water When Fixtures Are Off

 

Dripping, hissing, or running water sounds when no water is in use indicate a possible leak.

 

How to confirm:

 

  • Listen near walls, floors, or plumbing fixtures.

  • Check your water meter—movement means a leak is likely.

 

If you hear water but can’t locate the source, contact Repipe Champions for professional detection.

 

 

5. Cracks in Foundation or Wet Spots in Yard

 

Leaks can also occur underground in the main water line. A slab leak may cause:

 

  • Floor cracks or warm spots

  • Sunken, soft patches in your yard

  • Water pooling without rainfall

 

These issues may lead to foundation damage and should be investigated immediately.

 

 

How to Prevent Water Leaks

 

  • Inspect plumbing fixtures regularly.

  • Monitor your water bill monthly.

  • Learn the location of your main water shut-off valve.

  • Install a smart leak detection system for early alerts.
