    All this talk about Zoeller switches on M53 has me looking at the Liberty pumps.
    Specifically, the mobel 257 has a float switch that is a VMF which appears
    to be magnetic with a float. Any experience with the reliability of this
    technology????

    Also any opinion about 257 (cast iron housing) vs 237 (aluminum housing)??

    I know this is a VERY old post, but now 10 years later does anyone have any opinions on this? (VMF switch and the aluminum vs cast iron)?

    I've had excellent results using a HydroCheck HC6000 "Hi-Lo Sump Pump Controller" with a manual pump. No floats to hang up and no mechanical switches to go bad. There are two sensors so you can set the on/off height where it works best for your situation and to reduce short cycling.

    I also use a Basepump water powered backup sump pump. If you are on public water and not on a well they work great.

    I've installed a few Liberty model 230 pumps (manual, no switch) that are powder coated aluminum without any issues.
    I hope this helps.
