A climbing water bill in a Burnaby townhouse
Owners in a 1990s Burnaby townhouse complex noticed their water bill climbing month over month. Nothing looked wrong inside the unit, and neighbours weren't affected — which made the source hard to guess.

- Acoustic listening along the unit's supply line
- Comparison across the shared party wall
- Pressure check to confirm an active supply leak
A pinhole leak in a copper supply line inside a party wall, releasing a small but constant flow that never surfaced visibly.
A rising bill is often the only early evidence of a hidden supply leak. Acoustic detection located it precisely, so the opening was confined to a single section of wall rather than exploratory demolition.
