Not at all I made a couple of float switches out of 1 inch PVC pipe and end caps using reed switches magnets and fishing floats! The water rises in the PVC and activates the reed switches, this in turn is feed to the control circuit that uses and integrated circuit set up as a pair of comparaters that drive a couple of relay of which one drives a large relay that can handle the 1/2 hp motor on the well pump. Built it for about 20.00 and a few hours of design work and sure beats 300.00 for a new well pump. I am going to put instructions on my website. You can look at my pond there also. Bob
