ABSTRACT:
A pool water regulator has two vertical pipes which indicate the pool water level. Each pipe has a floating element disposed therein, and each float element has a switch secured to a distal end protruding from the vertical pipes. Brackets are mounted adjacent the switches so that as the float elements rise and fall, the switches are turned ON and OFF thereby activating either pool draining or pool filling means.
