ABSTRACT:
A device to restore the water level in a toilet bowl is disclosed wherein bleed water issued by the float actuated valve in a toilet tank reservoir is used to prime a syphon tube so that additional water from the toilet tank reservoir is shuttled down the overflow pipe to the toilet bowl to restore the toilet bowl water level during shortened partial flush operations of the toilet. The syphon tube consists of an inverted "U" shaped tube having one leg situated interiorly the overflow pipe and the other leg reaching down into the water of the toilet tank. The syphon tube operation is commenced by the bleed water injected into the base of the syphon tube through an initiator tube intersecting the syphon tube base so as to direct bleed water into the leg residing in the overflow pipe. An air vent opening situated in the initiator tube is effectively covered by water running through the initiator tube so no air is permitted to enter the syphon tube to disrupt the syphon operation. When the bleed water is terminated, air enters the base of the syphon tube and terminates the syphon action. Thus, sufficient water is conveyed to the toilet bowl to restore the pre-flush water level.
