H0W IT WORKS...
The self-cleaning strainers function by taking a small amount of the pressurized water generated by the pump and supplying this back to the strainer through a return line. The pressurized water drives the rotation of two internal flat-fan nozzles, which clean off the screen. The natural tendency for trash and debris to be drawn onto the screen by the pump’s suction is counteracted by the internal washing mechanism. The placement, size, and orientation of the nozzles are designed to maximize the cleaning capability for the amount of water used.
