Common Water Issue in BC

Unexplained High Water Bill

A significant increase in your water bill without a corresponding change in usage is the most common indicator of a concealed leak. Even a small drip can waste hundreds of litres per day, and underground leaks can waste thousands. BC's tiered water rates mean the financial impact increases with consumption volume.

Possible Causes

  • Running or leaking toilet flapper valve (most common cause)
  • Underground service line leak between meter and building
  • Concealed plumbing leak within walls, slab, or ceiling
  • Irrigation system leak in buried supply lines or valve boxes
  • Leaking water heater relief valve or tank failure

Recommended Steps

  • 1Read your water meter, turn off all water, and check again in 1 hour to confirm a leak
  • 2Check toilet tank water level and listen for running sounds
  • 3Locate your main shut-off valve — close it and recheck the meter to determine inside vs outside leak
  • 4Call for professional leak detection to pinpoint the leak location
