Save with every flush5 February 2007
Add a water hippo to older toilet cisterns to save 3 litres every flush - this has a payback period of 8-12 weeks and could save you £20 a year on metered bills. They're available from most DIY stores - for more info, see Hippo the watersaver and Hippo hotline. A water-filled 2 litre plastic bottle could also be added to your cistern - but will need to be checked regularly to ensure it is not interfering with your flush lever. (Don't use a brick - they crumble and the dust can clog up working parts of your cistern). New dual or low-flush loos are 2-4 times as efficient at saving water, and are available from approx £180.
