Hi everyone,
First post.
I would like to replace the above ground portion of my cast iron stack since there is a "pinhole" leak. However, the stack curves inward in the crawl space to clear the stone foundation with a curved fitting and I would like to make sure that I don't introduce any issues when replacing this with ABS fittings. Should I use 2 45 degree fittings after the pipe enters the floor with a short length of pipe in between on an angle to get to the cast iron in the dirt?
I have attached pictures of the existing stack going from 3" ABS to cast iron in the wall and the curved cast iron fitting in question.
I am assuming I should be using 4"ABS rather than 3" ABS to replace the 4" cast iron. Could someone please confirm?
If I cut open the stack and find that there is significant internal corrosion in the cast iron under the dirt, are there any solutions (like a sleeve or epoxy or something) to look into that don't involve digging up the whole cast iron pipe underneath the foundation?
Thank you!
