I bought the unit about a year ago as a spare and put it in service 4 days ago. It has the solid state water sensing switch. It does not turn off for 3-4 seconds after draining the sump down to the inlets and the gurgling/sucking noise during this time is horrible.
It it true that this switch will "learn" when to turn off? Is it a slow learner? Anything I can do other than buy a new float type switch to use?
The solid state switch sure sounded like a good idea.
All help is appreciated
