To safely thaw a frozen pipe, open the faucet it feeds and warm the frozen section slowly with gentle heat, such as warm towels or a space heater kept at a safe distance. Never use an open flame, and watch closely for leaks as the ice melts.
Signs a Pipe Is Frozen
On a very cold morning, a faucet that gives only a trickle or nothing at all is a strong clue. You may see frost on an exposed pipe or feel that one section is much colder than the rest. A toilet that will not refill can also mean its supply line is frozen.
Steps for Thawing Safely
- Open the faucet so melting water has somewhere to go
- Start warming the pipe closest to the faucet and work back toward the frozen spot
- Wrap the pipe in towels soaked in warm water
- Warm the room with a space heater set well away from anything that can burn
- Keep the heat steady and be patient
Only use electric heat if the area is completely dry. Water and electricity together are dangerous.
What Not to Do
Do not use a torch, a lighter, or a propane heater. Open flames can start a fire inside walls and can overheat the pipe. Do not pour boiling water on a pipe either, because sudden heat can crack it. If the frozen section is inside a wall or ceiling, leave it to a professional.
When the Water Starts Flowing
As the ice melts, check the pipe for drips or spraying water. A pipe can split while frozen and only start leaking once it thaws. If that happens, close the main valve right away and get the cracked section repaired before turning the water back on.
If you cannot find the frozen spot, or several lines are frozen at once, you can call a plumber who works in your area. JPR Plumbing is reachable at (833) 603-1840 on weekdays.
