How to install a water saving device

Save a Flush


Fitting a Hippo or 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 from our website. 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.
