The use of an adjustable wrench to remove the drain-plug is ill-advised. A rounded off plug will be extremely difficult to shift. Get a socket, or a drain plug wrench.

Someone forgot to install the filter gasket ring. They frequently can be found loose in the box, and can be forgotten if you dont know there should be one. But you wont do it a second time!
