What is a dual-flush cistern?
Traditionally people used lever flush systems where the lever was located on the side or front of the cistern and the full volume of water in the cistern was flushed every time. Increasingly, people are turning to dual flush technology which reduces the amount of water used.
With a dual flush system you can select either a half or full flush by pressing the appropriate button. Dual Flush systems generally have a 4ltr & 8ltr flush or a 3ltr & 6ltr flush.
