What should be done if a pipe is frozen?

When dealing with a frozen pipe, it's important to apply heat in a controlled and effective manner to prevent damage to the pipe. Slowly thawing the pipe using heat is the recommended approach because it allows for gradual warming, which reduces the risk of the pipe bursting from sudden changes in temperature. By applying heat gradually, such as through the use of a space heater, heat tape, or by wrapping the pipe with towels soaked in warm water, the ice blockage can melt in a safe and effective manner.

This careful method also enables any pressure buildup behind the blockage to dissipate more effectively, mitigating the risk of ruptures and leaks. Proper techniques can help ensure that the pipe remains intact while allowing the water to flow freely again. In contrast, other methods, such as using an open flame or pouring hot water quickly, can lead to rapid temperature changes that increase the risk of pipe damage or even igniting nearby materials. Natural thawing can be a slow process and may not be effective in colder environments, making the controlled heating approach the best option to resolve the issue.
