Abstract
A water level maintaining apparatus includes a main body element having an elongate shape and adapted to be supported by first and second support portions on the surface adjacent the edge of a swimming pool. An end portion of the main body element is supported in cantilever disposition inwardly of the edge or coping of the swimming pool above the water in the pool and a water level sensing device is mounted to the end portion. A conduit extends along the main body element and has an outlet end connected to a valve assembly and an inlet end connected to a water supply source. The water level sensing device includes a floatation element operable to float on the surface of the water and having a floatation arm connected to the valve assembly to selectively open and close the outlet end of the conduit to permit or prevent the flow of water from the conduit. The water level maintaining apparatus automatically senses variations in the level of the water in the swimming pool from a predetermined level and automatically operates the valve assembly to permit the flow of water into the swimming pool until the predetermined level is restored.
