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