Basically, its what is not said, it doesn't say "gaskets and seals", so they aren't covered, unless they need to be replaced in the course of a repair.
Only what is written as covered, is covered.
What I've described could be the only reason that I can think of that they wouldn't pay. Especially if the pump itself is covered.
