FW: Drain systems

> Hi, anyone out there like to comment on the following:
>
> I have a drain system to layout on a power job for dewatering and absorber
>
> building light slurried wash-down. What was a cast iron spec has been
> changed
> to PVC/CPVC, and general requirements are 3D minimum bends, no tees
> (laterals
> only) and a 5 degree minimum /10 degree preferred slope.
>
> We need short term delivery items for installation ASAP, but standard
> plastic
> catalogues do not indicate sweep elbows or laterals. Also the issue of
> out-of-
> true slope on fitting tolerances are not addressed in the vendor technical
> manuals - i.e. how far out-of-true
> fittings in PVC can be misaligned and retain joint integrity.
>
> Is a PVC system a good choice for this application - obviously weight and
> ease-of-installation are bonuses - or is it a poor substitute for cast /
> ductile iron?

> Thanks
