Just removed about 20' of 4" vertical cast iron pipe today, as there was a 3' crack in one section, and a bunch of random cracks in another, so im going to replace it with PVC. It ends with an abrupt 90° angle which then feeds into a bunch of cast iron T joints which all seem to be in good shape.
So, at the 90° it goes on for about 1-2' before tying in, which all seems to be in pretty good shape. Now, theres a TON of rust thats built up at the end of the "stack" and i was wondering if theres a decent method of removing the rust without having to worry about it clogging the rest of the line.
Also, what could i use up to patch up a crack in the pipe i want to tie into the PVC?
