brass drain tube replacement. I’ve done it and it’s not all that easy. You will be Googling Anealling. Not difficult if you plan to practice in advance and don’t blow a gasket if she splits. I have like 24” of quality brass, correct diameter tubing from McMaster-Carr if you need some. You need the tool. I used the socket type approach and it worked. Requires practice. Let me know.
