Why ABS instead of PVC?

Can't we disagree with each other politely?

Sorry for the rant, but I am confused by the overall tone. The sharp elbows are, without doubt, discouraging questions by newbies and others who really would like the benefit of the members' collective wisdom, which is considerable.

Thanks for considering this request!!

While I do respect your request. I didn't think this thread was so bad.
The conversation concerning "stuff flows downhill and payday is on Friday" is an old plumbers joke known by everyone in the trades.

I think the biggest point of this thread that Chum Lee shed some light on is PVC use vs. ABS is a very regional. Local Codes determine which product is used. The composition and additives used in ABS and PVC are regulated by local codes as well
If ABS is generally cheaper to manufacture as implied ealier in this post, than I'm sure the RV manufactures main reason for using it is price.
For the record I would have no problem using PVC in my RV. PVC is used exclusively in my area. ABS is not stocked at the big box stores or plumbing wholesalers in my area.
If I were concerned about the integrity of the pipe I may step up to schedule 40 PVC, otherwise I would just stick with foam or cellular core PVC pipe
