As pictured, this is my kitchen drain line and vent. It may be hard to see in the photos, but the 2" ABS goes into the concrete slab. Due to earth movement (my guess, and you can see the line isn't straight), the pipe is cracked right at the point entering the slab! This was causing drain leak into my patio luckily and not inside.
I opened it up and clearly see the crack, which hard to see in the photo, but marked in red. The green circle show the location of the clean-out on the other side of the wall in the patio.
So given the crack is at the same level of the top of the slab, I can't easily patch is up with a new section. This is where I need you brains :)
couple ideas came to me:
- Put a 1.5" ABS piece inside the 2" sealed with ABS cement.
- just use ABS cement to patch the crack from inside and outside, and then use flex rubber coupling to connect the rest (to release stress on the repaired part).
Thanks!
