ABS fittings
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?

In Canada, it's all ABS (inside a bldg.) and it's been used in residential construction since the 1950s. In the US, I think it depends entirely on the local jurisdiction. I've read that ABS is better in cold climates, but then I also read that ABS is required in California.
PVC expands & contracts from temp. changes a lot more than ABS and PVC is more brittle and for these reasons alone, maybe ABS is better in an RV? There is more of a procedure required for proper gluing (solvent welding) of PVC that requires the use of a primer before the cement and you have to hold a joint together for up to about 30 seconds. I can see this increasing the chances of failed joints by improper procedure at an RV plant. Gluing ABS together is much easier.
It seems like there were some problems with ABS because it was being manufactured with re-processed resin and now Calif. at least has new code requirements. California ABS code requirements Maybe problems with ABS prompted a switch to PVC? When you look at the various properties between the two, in the overall, one doesn't appear to be far superior and it would be interesting to know why some jurisdictions want only one or the other.
