No height sensor. Job was passed to a field service supervisor. May be that this unit is sensored in the lift pump. There is an electrical connector mounted to it. When he manually lowered it, the lift height maximum also lowered. Now were in the same boat and the lift raises to an even lower point. Will post updates on progress.
