You are here : At Home > My Water > How to guides > Water saving device - Save A Flush
If you have a large seven or nine litre cistern, this little bag of biodegradable polymer swells on contact with water and effectively reduces the size of your cistern, saving water with every flush.
Two types are available for FREE. They are not suitable for dual flush toilets or for cisterns with a capacity of less than 7 litres. For modern, dual flush cisterns, all you need to do press the smaller button to save water.
They are easy to fit. Just unpack, lift the lid of the cistern and put them in the correct location - that’s it, it’s that simple.
