The autofill switch is a few inches below the air switch that opens the main sewer valve. There is an electric solenoid which is plumbed into the exhaust side of the two water pumps and empties into the tank about three inches from the top of the tank. My owner's manual states that the pumps should be left on even when connected to city water to maintain adequate pressure. Looks like I need to sort out the plumbing to figure out what is going on. In a previous post, I mentioned that when I tried to fill with the autofill, the water pump ran, filled the tank, and then shut off, but there was overflow. I have been advised to remove the solenoid and clean out a small hole that is intended to shut off the flow of water. Perhaps tomorrow I will check out this small hole to see if it is stopped up.
