ABSTRACT:
A water level control device is adapted to be detachably mounted within a swimming pool at the desired water level. A float controlled valve is mounted within the housing which is responsive to changes in the water level of the swimming pool and which is provided with a water inlet and outlet located outside of the housing so as to prevent turbulence within the housing. A suitable air vent is provided adjacent the top of the housing above the water line and restricted water inlet apertures are provided adjacent the bottom of the housing below the water level to maintain the water level within the housing at the same level as the water level in the pool.
