I have found a cracked 1 1/2" fitting on my grey drainage system but am not finding much of a selection of these available at Ace, Home Depot or Lowes. Are they phasing out ABS?
Since it is a drain line you might try a repair.. GOOP seems to stick to that stuff in my experience,, Work it into the crack and smooth a small mount for about 1/2 inch either side of crack and let it dry overnight. Fill tank with at least 10 gallon of FRESH water and dump.. Odds are it won't leak
This gives you a lot of time to find a proper coupler.
