Save up to 1 litre of water per flush
The Ecofill version doesn’t start filling until the cistern has emptied. This means the optimum amount of water that the pan requires is used. Without this functionality, the water from the next fill flows out as part of the flush, unnecessarily wasting water. This particular fill valve can save over 1 litre of water per flush.
