I have a waste pump in a pit for the bathroom and sink in the basement. The pump is controlled by a float switch (the cylinder type that attaches to the pump). From time to time, there is this "white stuff" that sticks to the switch. As a result, the swith is too heavy and not float. I often need to break the white stuff apart.
Are there anything I can use to get rid of the white stuff or a different type of switch that is not affected by the stuff? Thank you.
