Toilet flushing

About 27% of the water used inside the home is flushed down the toilet. Water can be saved with better habits and technology, even in the smallest room in the house.

  • If you need a new toilet, use the Water Rating label and buy a water-wise toilet. Look for models with a 4-star rating or higher.
  • Make sure you use the appropriate flush button. Generally, try to use the half flush and save the big button for the big jobs!
  • If you don’t have a dual-flush toilet, you can buy a toilet-flush regulator from a hardware or plumbing store. These devices fit inside your toilet cistern and allow you to control the amount of water used each flush by shutting off the flow of water when you remove your finger from the button. The longer you hold the flush button down, the more water will be used.
  • As an alternative to a flush regulator you can improvise a reduced flush simply put a water-filled plastic bottle inside the cistern (the top bit that stores the water) of an old single-flush toilet. This will reduce the capacity of the cistern by the volume of the bottle. For example, if you put in a 1.25 litre filled plastic bottle then each time you flush you will use 1.25 litres less water.
  • Consider getting special plumbing to collect and use rainwater or greywater for toilet flushing. You don’t need crystal clear water to perform this task!
