Always something to work on.
After shining a bright light in the commode, the pipe is black and appears to be part of the flange. I still would like to cut it if it isn't too much work. I may try to put a valve on the shower, spray water down the commode and try to keep it clean that way if I can't get info from someone that knows how it is put together. The picture is not very good but it is all we could get. Thanks
