A liquid level control apparatus for a flush tank includes a valve mechanism communicating with a fill tube and operable between open and closed conditions, two floats, at least one of which is coupled to the valve mechanism for closing it when the at least one float reaches a predetermined height, and structure interconnecting the floats so as to substantially prevent their vertical movement until a predetermined liquid level is reached corresponding to the predetermined height, thereby causing sudden movement of the at least one float to the predetermined height and sudden closing of the valve.
