Here’s a deep, step-by-step guide to thawing a frozen drain, covering diagnosis, methods, prevention, and when to call a pro.

For sinks and drains that are accessible under the cabinet, the safest and most common thawing method involves the strategic application of hot water. However, one should never pour boiling water directly into a frozen drain. The extreme temperature shock can cause brittle pipes, particularly PVC or older metal ones, to crack. Instead, the homeowner should use hot tap water or water that has been boiled and allowed to cool slightly. Pouring this water into the drain, combined with a moderate amount of table salt, can help lower the freezing point of the ice and accelerate the melting process. This method requires patience; it may take several kettles of water to clear a stubborn blockage. how to thaw a frozen drain
