If you've removed the compression nut and gasket there should be nothing stopping the trap tail from just slipping out of the stub-out. Do you have enough room behind the fitting to cut the fitting out and start from scratch?
The trap tail just slips inside the wall stub-out and is held in place by the compression nut and gasket. Remove them and it should just slip right out. What makes yours different? Regards, Tom
