ABSTRACT:
An insert installed inside the toilet tank arranged and constructed to decrease the amount of water held in the tank. While the amount of flushing water used for each flush is appreciably less than it would be without this insert in place, the bulk of that water is still delivered to the toilet bowl under an average head higher than that which is normally obtained without the insert. The toilet flushing action is thus as effective as it would be otherwise, but only with a fraction of the water volume being required. The resulting saving of water is substantial and the tank also fills up at a much faster pace. The insert is supported by the bottom and side walls of the existing toilet tank and does not otherwise interfere with the operation of the toilet tank internal equipment. Because no water is allowed to flow between the insert body and the toilet tank walls, this space being sealed off, this insert also provides safety in case the toilet tank walls are accidentally broken.
