Been searching for hours now and need answer soon.
Thank you in advance.
My house is built with cast iron piping due to it being 4 story. My question is regarding the bath drain and ptrap,. The pipe underneath is cast iron. Do I have to make the drain portion and ptrap metal as well? Or can I use ABS. Would ABS handle the pressure test with that amount filled with water at the lowest level?
