You Should Never Pour Hot Oil Down Your Sink Drain, and Here’s Why

It’s definitely not recommended to pour oil down the kitchen sink. While your mother-in-law might think it’s okay, doing so can lead to significant plumbing issues and environmental problems. Here’s why it’s important to avoid this practice:
Reasons Not to Pour Oil Down the Kitchen Sink

Clogged Pipes: Cooking oil can stick to the insides of pipes, leading to blockages over time. This can result in slow drainage or complete clogs that require costly repairs.
Fatbergs: In sewer systems, oil can combine with other waste, forming “fatbergs”—massive clumps of fats, oils, grease, and non-biodegradable materials. These can severely damage municipal sewer systems.
Environmental Impact: Blocked sewage systems can overflow, leaking contaminants into local waterways, harming aquatic life, and polluting drinking water supplies.
