Putting boiling water down the drain can be OK for metal pipes, as it can help dissolve organic material and clear minor clogs. However, for PVC pipes, it's generally not recommended. Boiling water can soften or damage PVC pipes, leading to potential leaks. For routine maintenance, a safer choice is hot, not boiling, water mixed with dish soap. For significant clogs, consider using a plunger, a plumber's snake, or a chemical cleaner formulated for the type of pipes in your home.
