: I'm trying to install a new bathtub in my upstairs bathroom. I brought a new overflow and drain unit. Everything was going well until i went to connect the tailpiece into the existing drain. Seems the old pipe wore out and snapped off inside, now i cant get the new tailpiece to seat into it.What would be the easiest way to connect the two? They are both brass. If i were to exchange the brass system with PVC,is it possible to connect the PVC into the brass fitting? Silicone,epoxy,etc? Thanks in advance for any advice........John
