If you've got an outside antifreeze connection, it could be that the valve near the water pump is still set to pull from the antifreeze inlet. On my 20BHS, our valve points to the hose that pulls from the fresh water tank. If i rotate the valve to be parallel to the line, it will pull from the antifreeze inlet.
