Boiling Water Down Drain ((link)) -

When boiling water hits a plastic pipe, the intense heat instantly softens the synthetic material. Under the weight of the water and the structural pressure of the house, the softened pipe can warp, sink, or lose its perfectly sloped shape. Once a drain pipe loses its slope, water and debris will pool in the warped sections, creating chronic, recurring clogs. 2. Melting Joint Adhesives

PVC pipes are a major concern – they soften around 140°F and can deform. Also, wax seals on toilets can melt. Even metal pipes might have weak joints. There's also a scalding risk for anyone using the faucet.

Run the tap to see if the flow has improved. The "Dynamic Duo": Baking Soda and Vinegar He stared at the pot

Professional plumbers often recommend using enzymatic drain cleaners (which use bacteria to eat organic waste). These cleaners require warm, not hot, water to activate. However, if you pour cool water first to activate the enzyme, waiting 15 minutes and then following with can help flush the digested material out of the lateral lines. Just ensure the pipes are metal or schedule-80 heavy PVC.

For more stubborn clogs, combine the heat with a chemical reaction: 12one-half cup of baking soda down the drain, followed by 12one-half cup of vinegar. Let it fizz for 15–20 minutes. Follow up with a large pot of boiling water. Important Safety Precautions

Modern PVC (polyvinyl chloride) pipes can withstand high temperatures, but prolonged or repeated exposure to boiling water can soften them or weaken the joints, causing leaks.
