I know that you said that the air is out of the lines, but it sounds that there is air in the lines. Be sure that a sink faucet is open, then run the pump.

I ran it for several minutes. All the downstream air is out of the system. There's a clear cover on the inlet side, and nothing was flowing through that, except like I said when the winterizing valve was open... making ZERO sense.
