Can’t upgrade right now?

If you can’t install an efficient toilet right away, here are some alternatives:

  • Reduce flush volume in single flush toilets by installing a cistern weight or converter, it will stop the water flow as soon as you take your finger off the button.
  • Save up to 1 litre per flush by modifying the float arm or installing a displacement device, such as a plastic bottle filled with pebbles and water – this will reduce the volume of water in the cistern. Remember to check the toilet bowl functions as required when using this method.
  • Some pans with an 11 litre single flush cistern may work with a replacement 6/3 litre (6 litre full flush and 3 litre half flush) dual flush cistern. Please check with the manufacturer prior to making the change.
  • Fit a hand basin conversion kit to the top of your toilet cisterns – they use grey water from the basin to flush the toilet.
  • If you have a flusherette system, insert a flow control regulator into the valve body to reduce the flow rate by up to 30%.
