Common Water Issue in BC
Condensation on Water Pipes — Sweating Pipe Issues
Excessive condensation on water pipes can cause moisture damage that mimics a leak. Understanding the difference between condensation and actual leaks is essential for BC homeowners.
Possible Causes
- •High indoor humidity causing condensation on cold water pipes in summer
- •Inadequate pipe insulation in unconditioned spaces like crawlspaces
- •Cold water pipe temperature below dew point of surrounding air
- •Poor ventilation in pipe chases and mechanical rooms
- •Humidifier set too high creating excess moisture in the air
Recommended Steps
- 1Check if moisture is on cold water pipes only — condensation is cold, leaks can be hot or cold
- 2Wipe pipes dry and monitor if moisture returns — condensation returns quickly, leaks are constant
- 3Measure humidity levels — target 30-50% in summer
- 4Insulate cold water pipes in unconditioned spaces
- 5If moisture persists after insulation and humidity control, call for professional assessment
