Hidden Leaks Before Damage Spreads Tips

 

To find a hidden water leak, check your water meter, look for water stains, and listen for running water. Local residents can log into MyWaterToronto to monitor usage data and check for continuous flow indicators.

Warning Signs

  • High Bills: A sudden jump in your water cost without extra use.
  • Odd Smells: A damp, musty odor in rooms or hallways.
  • Wall Marks: Yellow or brown water stains on drywall or ceilings.
  • Sound: Faint hissing or dripping behind walls when taps are off.

Detection Steps

  • Test the Meter: Turn off all taps and water tools inside and outside. Look at your meter dial or flow indicator; if it moves, water is escaping.
  • Check Toilets: Put a few drops of food coloring in the tank. If color shows in the bowl without flushing, the flapper leaks.
  • Feel Surfaces: Touch floors or walls for soft spots or weird warm/cool areas.
  • Call a Pro: Hire a local expert like Canadian Leak Detection if you cannot find the exact spot.
