The fitting at the bottom should look just like the water inlet fitting or vent at the top. Nice clean factory fitting. So... I don't know why it has been plastic/welded or have sealant around it if it is 'new'.
Also, my concern was drawn to the dangling white wire that is in the picture. It looks to be 110 volt wire and IMO should be secured and have a protective cable cover over it so it would not be subject to any chafe.
