Abstract
A fluid discharge regulating device to be used for conserving water in the toilet tanks of bathroom toilets. The device includes partitions that divide the toilet tank into three consecutively arranged compartments, each compartment providing fluid communication with other compartments, either directly or indirectly, through portholes in each partition. Each porthole opening is adjustable to control the rate of fluid flow into the second or middle compartment in order to maintain constant the amount of water used during a single flush. The volume of fluid reaching the toilet bowl can be increased beyond the preset level by holding down an adjustable handle which is connected to the flushing mechanism.
