An improved fluid control means for a flushing tank comprising the combination of: an inlet fitting adapted for being coupled to a source of liquid under pressure and for being mounted within the tank; a float movably mounted on said inlet fitting for movement between raised and lowered positions responsive to the level of liquid in the tank; an inlet valve having a valve cavity including a plurality of outlet ports and first and second shut-off means positioned within said cavity; said first valve shut-off means comprising a valve seat in one of said outlet ports and a port sealing ball movably mounted within said cavity for movement off of said seat by float coupling means and against said seat by the force of liquid flowing through said one port; means operatively coupling said float to said ball for moving said ball from a closed to an opened position at said one port against the pressure of liquid on said cavity; said second shut-off means comprising a disc-like flexible diaphragm positioned within said valve cavity and operable to open and close a second of said ports by the liquid pressure in said cavity in response to the position of said ball; said float including a liquid chamber communicating with the said outlet ports and having a fluid drain in said liquid chamber permitting drainage therefrom giving said float a varying bouyancy; a flushing valve for the flushing tank comprising a hollow tube and means for movably mounting said tube in said tank; a sealing washer mounted on a lower portion of said tube for engaging and sealing a tank outlet; float means on said tube; said mounting means for said tube including means for lifting the tube to a floating position in liquid in said tank; and a bowl leveling aperture in the upper portion of said hollow tube for bowl leveling drain-down while said liquid chamber in said float is draining and said tube is sealing the tank outlet.
