I am curious to know if the lower o ring needs to be set somewhere on the shaft. The upper one needs to be set so its just below the overflow fitting but the lower one was set on the bottom of the shaft. The float moves up and down freely but should the float rest at the bottom of the shaft and rise up and down with the water level or should it be set higher up so it only hits the top o ring in the event of a malfunction??Name:  Brine Float 002.jpg
