Couldn't you just mount the float switch upside down?

We don't know what kind of float switch the TS has. IF the TS has a float switch like that pictured in post #13 then mounting it in any orientation will only result in turning the pump on when the float tilts up and rolls the contact ball to the inner contacts completing a circuit which then activates an ejector pump (sump pump). It also offers no hysteresis. The pump may cycle frequently resulting in premature pump failure.

 

The TS has not responded since post #6, Feb. 16th. It's possible we've scared him/her off.

Unwatching this thread.
