T&T: Rigid PVC plumbing

[Capefearboat at aol.com]

Sealand's installation manuals show pictures of sch 20 PVC pipe in 
non-pressure blackwater usages. I believe that as long as the piping is well supported 
and not stressed what would cause it to crack? We regularly use sch 40 but some 
long elbows are only available locally in sch 20 so we use that as well. I 
think sch 80 is not necessary. If you need that you may be better off with 316 
stainless steel metallic piping.
