ABSTRACT:
The water level of an above-ground swimming pool is maintained at a predetermined level by a small tank attached to the edge of the pool. The tank bottom has an aperture for a conduit to the pool through the side wall thereof, whereby the level of the water in the tank is the same as the level of the water in the pool. The pressure sensor switch is designed to open when the water level in the pool falls below a predetermined amount, and to close when the water level is restored thereto. The pressure sensor switch is activated by the level of the water in the tank, but when open delivers water from the house line directly to the pool.
