Why is it better not to pour cooking oil and grease straight into kitchen drains

When hot oil or greasy water goes down the drain, it’s liquid. But as it cools, it thickens and sticks to the inside of pipes, catching food particles and creating a sticky layer. Over time, that layer narrows the pipe and leads to slow drains or full blockages.

Instead, you can wipe oily pans with a tissue first and put that in the trash, or pour cooled leftover oil into a container to discard separately. Letting oil solidify and scraping it out is much kinder to your plumbing than washing it all down.

A little bit may not seem like much, but months of “little bits” become a big problem.
