Is your sink draining slow? Don't call a plumber for R500 yet. Try this first.
1. Pour 1 cup baking soda down the drain. 2. Pour 1 cup vinegar. It will bubble. 3. Leave 15 minutes. 4. Pour a kettle of boiling water slowly. 5. Run tap. Your drain should be clear.
Do it twice. Remove hair from the drain cover. Don't pour cooking oil down the sink, it blocks drains.
