Water Efficiency
Reducing water wastage through delayed action
UK toilets needlessly flush away 1.2 billion litres of water a day (Waterwise).
The graph below (adapted from WRc data) shows that the actual flush volume for a nominal 6 litre WC increases as pressure increases. The Cistermiser easyflush will maintain the nominal volume at all pressures due to its patented delayed action operation.
Installing a Cistermiser easyflush can save up to 403,000 litres per year as shown below.
