The waterstop cistern weight is one of the most economical retrofit devices available to reduce water usage on a standard flush toilet. Simply insert the cistern weight into the outlet valve of the toilet to turn your single flush system into a demand flush system.
Note: When flushing, you will need to hold the handle down for the desired flush, as this device will not automatically empty your cistern when flushing.

saves alot of water as the whole cistern doesn’t empty every time you flush
