I couldn't find the answer to my problem here or anywhere online, so here goes:
I have a guesthouse above my garage. Galvanized drain lines underneath under the ceiling of the garage need to be replaced. I thought I read somewhere that ABS is not allowed unless in the floor joists (and covered by fire retardant drywall. So, three questions:
1. Does this mean I have to use Cast Iron?
2. If I do, I assume I can use no-hub and Fernco couplings?
3. If so, can I also use the Fernco Ys and elbows if need be?
I'm in Los Angeles.
Thanks,
jason
