Think Before You Pour

Oils and fats that are used in cooking harden inside pipes when poured down the sink. This can cause blockages and sewer flooding to your home and garden. 

What not to pour down the sink?

Cooking oils, meat fats, lard, shortening, butter, margarine, sauces, dairy products and food scraps.


  • Wipe and scrape plates before you wash them in the sink
  • Collect all used cooking oil into a suitable container
  • Use strainers in skin plug holes to catch any bits and pieces of food in your sink and then empty them into a suitable bin]


  • Put fats, oils or grease down the sink
  • Put food scrapings into the sink
  • Pour harmful chemicals down the sink or drain to try and dissolve fats, oils or grease
