Why grease clogs drains
Fats, oils and grease solidify as they cool in pipes. Over time, they build into thick layers that narrow the pipe. They also contribute to blockages in municipal sewers.
Better habits
- Pour cooled grease into a container, such as an empty can or jar.
- Blot pans dry with a used napkin first.
- Clear plates into the organics bin.
- Fit a basket strainer in each kitchen drain.
- Avoid the disposal for greasy or fibrous foods.
Peel green bin. The Region of Peel has accepted small amounts of cooled cooking grease in the green bin. Check the current program details before relying on this.
Hot water myth
Chasing grease with hot water simply relocates the clog a few metres along, where the fat sets just the same.
Signs of grease build-up
- Kitchen sink that drains slowly
- Gurgling from the sink
- Odours from the drain
If the kitchen drain is already slow, professional cleaning may be needed; see kitchen drain cleaning. Persistent basement water is a different issue; see sump pump repair. Mineral build-up is another kind of deposit; read signs of hard water.
Worth knowing
Answers our Mississauga crew gives most
Can I pour vegetable oil down the drain?
No. Liquid oils also coat pipes and cause clogs.
Does dish soap break up grease?
Briefly, but grease separates again further down the pipe.
What about large amounts of oil?
Check Peel's waste program for drop-off options.
