That, and many installers just press fit the fittings, it's
low pressure after all.

Are you sure you can't get the PVC vent loose and swing it
aside?
Me and my bud I do AC work with never install a 3/4 PVC
drain without
a union so we can service the drain if it clogs up. You can
cut the
3/4 drain line and install a coupling without glue so you
can get it
loose. I always use unions anyway. With the 3/4 drain out of
the way,
you could easily remove the cover. Big box stores have the
unions.
