Abstract

A timed pressure equalization member for use in a siphonic toilet to reduce water loss at the end of a flush cycle is disclosed. The equalization member functions to equalize the pressure in a pressurized chamber after a set period of time and consequently alleviates negative pressure within a pressurized trapway system at or near the end of a flushing cycle via a conduit, to help break the siphon at the end of the flush cycle, thereby reducing the amount of water drained from the water bowl/spot while the bowl is being refilled. At a resting state, the equalization member in the pressurized chamber is partially filled with water. The equalization member empties of water after a set period of time during a flush cycle and allows atmospheric air to enter the pressurized chamber (in fluid communication with the pressurized trapway) at or near the end of the flush cycle.
