Frozen Pipes? How to Safely Thaw Underground Water Lines in Ontario

No water in your home or shop this winter?
If temperatures have dropped and your taps have suddenly stopped flowing, you may have a frozen underground service line.

Ontario winters regularly cause deep frost conditions that freeze private water service lines — especially copper lines running from the street to your building.

The good news? There is a safe, professional solution that does not require digging up your yard.

Why Underground Water Lines Freeze in Ontario

  • Prolonged extreme cold
  • Shallow buried service lines
  • Lack of snow insulation
  • Recent excavation near the line
  • Poor soil drainage

Signs your underground line may be frozen:

  • No water from any tap
  • Pressure dropped before full stoppage
  • Neighbours still have running water

This is different from interior plumbing issues and requires specialized thawing equipment.

The Safe Way to Thaw a Frozen Underground Service Line

At Rental Village, we rent professional pipe thawing equipment designed specifically for metal (copper) or PVC underground service lines.

Why You Should Avoid DIY Methods

Using torches, open flame, or improvised heating methods can:

  • Damage pipe joints
  • Create leaks after thawing
  • Cause fire risk
  • Lead to expensive plumbing repairs

Professional thawing equipment significantly reduces these risks.
