ABSTRACT:
Apparatus for monitoring and controlling the level of water in a swimming pool includes a vertically elongated vessel partially-buried below the pool water level at a location close to the return line from the filter to the pool inlet, a connector pipe extending from the vessel to the return line for allowing pool water at sub-level pressure to enter the vessel and rise to the pool water level, and a float-controlled valve supported within the vessel and detachably coupled with a pressure water supply and adapted to open as the float drops below a predetermined desired level and allow fresh water to flow into and out of the vessel through the connector pipe and return line and then into the pool for restoring the water in the pool to the predetermined desired level as determined by the position of the float on the water within the vessel being restored to a float position indicative of the predetermined desired level of water in the pool.
