After reading the above posts, I decided to test the auto fill using city water. Turned the switch on in the water bay, some electrical system, maybe a pump, started and ran until the tank was full. The two Surflo pumps were automatically shut off, thus no water at the faucets. Finally, all noises stopped, but the tank overfilled and ran out on the pavement. Not sure what is going on, but I reverted back to my old procedure - manually fill the tank and dump the sewer at the same time.
