Yes John, take it all apart and just change the rubber seal.
Problem you will run into is bending the tabs. Gotta be
careful bending them up cuz it's hard to get under them. Then
you will have a hard time bending them back down tight so the
whole thing doesn't leak. Then you have to hope that one of
the tabs doesn't fatigue and break off.
Alvin un-soldered the plug in the bottom and disassembled the
whole thing. Hope your a good plumber/solder slinger if you
choose to go that route.
