I decided to check the shower sump pump today to make sure it's working as we're taking a week long trip starting next weekend. The sump was full, so I pulled the pump and checked for power, had 13 volts. I messed around with the float and it started working....... backwards. It comes on when the float is in the down, or sump empty position, goes off with the float in the up position. I ordered a new one, but i thought that is weird. Maybe I'm missing something.
