Night calls and burst water

Thawing frozen lines

Frozen supply lines thawed with controlled heat, never a torch, then checked for hidden cracks before the water is turned back on in Toronto homes.

When a tap coughs out a dribble or stays dry on a bitterly cold morning, a frozen pipe is the likely cause. Ice alone rarely does the harm. What splits copper is pressure trapped behind the ice, against a closed faucet, with nowhere to escape.

Finding the frozen section

  • We start at the coldest likely spot: supply runs hugging outer walls, the cabinet under a sink on a cold wall, in unheated crawlspaces and garages, and the hose bib line passing through the rim joist.
  • A non-contact thermometer helps us find the section that reads well below the rest.

Clues it is this job

  • One tap dry while others work
  • Frost on exposed pipe
  • A toilet that will not refill after a cold night
  • Gurgling or banging when you open a tap

Thawing without damage

  • We open the nearest tap so meltwater has somewhere to go, then warm the pipe slowly with a heat gun, heat cable or a pipe-thawing machine on metal lines.
  • An open torch never goes near a frozen line inside a stud bay.
  • Thawing too quickly can turn a hairline crack into a flood.

Stopping it happening again

  • After the water flows we check the thawed section under pressure for weeping.
  • Then we look at why it froze.
  • Sometimes it is a missing piece of insulation at the rim joist, sometimes a pipe that was moved into an exterior wall during a kitchen renovation.
  • We explain the options, from foam sleeves to rerouting.

Leaving a cabinet door open under a sink on an outside wall lets house heat reach the trap and supply lines.
