Tom,

I think you are on to something here. Several of us have noticed that our water pumps act wonky especially after filling the tank. I have always thought that air was getting into the feed line in bottom of tank, but what you may have figured out is that if the valve sticks open, it will allow air in the line. That in turn could cause the water pump to cycle.

So you have completely removed your autofill?

Could this be a thing?
