Looks like we have a small leak in the y-connector of our sewer stack just before it goes into the basement floor.

In the past, I simply added glue to where the leak was.

Possible Fixes

• Plastic welding and addition of additional melted ABS. 
• Remove everything and redo... Uhhhg
• ABS bandaid - glue new piece of ABS over crack.

What I am Going to Do

Add a riser clamp to support the pipe. This is probably why it cracked in the first place.

Patch the pipe using ABS glue and fibreglass.

Steps:

1. Dry completely

   • No moisture at all (fan + time)

2. V-groove the crack

   • Use a Dremel or file to open the crack slightly

   • This gives cement something to bite into

3. Flood with ABS cement

   • Work it into the groove

4. Wrap tightly with fiberglass

   • Fiberglass mesh or cloth (not tape)

   • Wrap around the heel and as much of the branch as possible

5. Saturate the wrap with ABS cement

   • Multiple coats

6. Cure 24–48 hours
