Standard package includes three 20' Sensor Float® control switches 3-year limited warranty UL/cUL Listed Another common approach to the problem is a Duplex pump arrangement with or without a alternator. Thought is a lot of the time 1 pump may be enough flow, so why run / cycle a bigger pump more often. Any and all mechanical items (pumps/motors) fail or have a problem (prime, debris) and if that happens 1 pump is not going to do its job. Duplex avoids these issues. Then if you add a duplex alternator control starter you get the best of all worlds. 1 pump (alternating) will start and try to handle the flow. If it can not keep up OR has a problem the second pump kicks in. Exercises each pump in a alternating fashion for long life. Fulfills the need to have a branch motor control switch / circuit (NEC). Last but not least the cost may be less due the smaller single phase motor.
