I am about to start a bathroom renovation. The bathroom is going to be gutted, new sub-floor, doubling up the joists among other things. I was planning on replacing the tub drain, as it is very slow because of years of build up. The house was build in 1960, and these are the original pipes. The house is a single story ranch, and the whole sewer stack is in one place. The only thing not near it is the kitchen drain, and that was converted to PVC years ago.
I am thinking of redoing all of the cast iron in PVC (or ABS) while doing this. I am not a professional plumber, but am a pretty good handyman. The job seems straightforward enough, but I wanted to make sure I am not getting in over my head.
The picture below is my sewer stack. I labeled where all the drains come from. I have one large one I am not sure where it leads, but I am going to open the wall to find out. Anyway, given the picture, is this something I can handle myself (father and friend will be helping, but they aren't professionals either)?
Any tips would be appreciated. Let me know if more information is needed.
