Finally did this. Had to prep to make sure there was no forensic evidence afterwards for my wonderful spouse to find. Very easy with one of those $10 round plastic pans with the spout and handles.
Only issue I had was removing the small o-ring. Didn't want to roll off or lift with my fingers and I was concerned about damaging the plastic with a screw driver. Decided to flex it with tweezers and get under it with a small staple. Worked, but thought it was pretty stubborn.
