The answer: No, you should not pour oil down the sink.
Pouring oil, grease, or fat down the sink can lead to serious plumbing issues. These substances solidify as they cool, potentially clogging your pipes and causing blockages. Additionally, once in the sewer system, oil can contribute to larger problems, such as fatbergs—massive buildups of fat and debris that can block entire sewer lines.
Instead, allow the oil to cool and then dispose of it properly. You can pour it into a sealed container and throw it in the trash or take it to a local recycling facility if they accept used cooking oil. This helps protect your plumbing and the environment.
