1. Unexplained Spike in Your Water Bill

A sudden increase in your water bill—with no change in usage—is one of the most obvious signs of a leak.

How to Check:
• Turn off all water-using appliances and fixtures. If your water meter is still moving, you likely have a hidden leak.
• Compare your current bill with previous months. A consistent rise could mean water is escaping somewhere behind the scenes.

What to Do: Don’t wait—leaks only get worse over time. Contact our leak detection specialists for a professional assessment.


2. Water Stains on Walls, Ceilings, or Floors

Discoloration, bubbling paint, or warped baseboards often point to moisture behind walls or beneath flooring.

Common Causes:
• Hidden pipe leaks
• Roof or fixture leaks
• Faulty appliance connections

Warning: If water stains are expanding, you’re dealing with an active leak that needs immediate attention.


3. Mold, Mildew, or Musty Odors

Smelling mold or seeing mildew in normally dry areas—like inside cabinets or behind toilets—may indicate a persistent leak feeding unwanted moisture.

Where to Check:
• Under sinks and dishwashers
• Around water heaters
• Behind walls or in crawlspaces

Health Note: Mold can trigger allergies and respiratory issues—don’t delay inspection.


4. Hearing Water When Nothing’s Running

If you hear dripping, hissing, or flowing water when all taps are off, that’s a strong sign of a hidden leak in your system.

To Confirm:
• Listen near walls, floors, or near appliances.
• Check your water meter—movement means water is flowing somewhere.

Tip: Call Repipe Champions for professional leak detection using advanced tools.


5. Wet Spots, Yard Sinking, or Foundation Cracks

Some leaks occur underground or beneath your home’s slab foundation. These are harder to detect but can be extremely damaging over time.

Look for Signs Like:
• Hot spots on flooring (from hot water line leaks)
• Sunken or soggy patches in the yard
• Water pooling without recent rain
• Cracks in flooring or foundation

Act Fast: Slab leaks can compromise your foundation and lead to major repair costs.


How to Prevent Water Leaks
• Inspect pipes and fixtures regularly
• Monitor your monthly water usage
• Know where your main shut-off valve is located
• Consider installing a smart leak detection system
