A water conserving apparatus for flushing various domestic and industrial vessels such as a restroom fixture commonly known as a Water Closet. The main element of this apparatus is a normally retracted controlled retraction enclosure that resists expansion at a predetermined pressure. Head pressure, a necessary ingredient to produce an efficient flushing action, is synthetically created by storing flushing medium in a valve controlled, fully expanded, controlled retraction receptacle. The operator controlled opening of the valve causes the flushing medium to be released and pushed out at the predetermined resisting pressure of the retracting controlled retraction container. The released high velocity flushing medium is directed to the vessel to be flushed. When the flushing cycle is completed, the valve automatically resets and the controlled reaction receptacle refills with the flushing medium.
