Prevent your skimmer from overflowing without modifying your skimmer. The float switch clips onto the skimmer lid and the wired feed out the skimmer air holes. Simply hook the float up to an Apex breakout box. There is about 1/4" adjustment in the float height by unscrewing the float. I believe this will work on a majority of skimmers.
