A 'Save-a-Flush' is a water absorbent plastic bag which, when dropped into a toilet cistern, expands and takes up some of the space that would normally be filled by water. Each time the loo is flushed it saves approximately one litre of water.
Sound good? You can order one for free here.
Please note, we don't advise that you use a 'Save-a-Flush' in a cistern which has a dual flush mechanism (2 buttons), as these are already water efficient.
