I need to remove the shower drain to repair a cracked shower pan. The pan is plastic, an oddball size, and in a location where it can't be replaced without major demolition.
I tried to unscrew the drain fitting with a pop-up plug wrench, but only managed to strip the inside of the drain clean out.
Now the wrench has nothing to grip. It just slips inside the drain fitting.
Does anyone have any tricks to getting the drain apart? I've got plenty of brute force solutions, but I'm hoping someone has something a bit more elegant.
