ABSTRACT:
A system for automatically maintaining a desired water level in a swimming pool, includes a float chamber coupled in fluid communication with a suction tube that is coupled between the pool and a pool filter pump. A float carrying a magnetic element is disposed in the float chamber. A magnetic switch is located in a fixed position outside of the float chamber at a level corresponding to the desired water level. The magnetic switch assumes a first state if the pool water level is equal to or higher than the desired water level and assumes a second state if the pool water level is lower than the desired water level. A solenoid valve is connected between a pressurized water source and an intermediate portion of a return tube returning pumped water to the pool. A circuit is coupled to the valve and the magnetic switch to close the valve when the pump is operating, and open the valve when the pump is not running and the magnetic switch is in the second state.
