Abstract: There is disclosed a level control valve arrangement preferably for use in a water closet cistern for controlling the liquid level in the cistern or container. The arrangement has a liquid inlet (3) feeding an inlet chamber (1) and a movable valve member (7,10) mounted on a seating (11,12) and movable between an open position in which liquid flows from the inlet into the cistern and a closed position in which liquid is prevented from flowing into the cistern. The movable valve member is biased preferably by a float arm into the closed position in response to liquid in the cistern rising to a predetermined level. The movable valve member (7,10) is mounted in the inlet chamber into which water is fed from the inlet (3) and in the closed position the valve is acted upon by a head of water in the inlet chamber to maintain the movable valve member in the closed position.
