Water piping for the distribution of hot and cold water within building shall be of material listed in Plumbing Codes. Most commonly used material for water supply pipes is CPVC(Chlorinated Poly Vinyl Chloride, PP-R (Polypropylene) and PB (Polybutylene). CPCV stands for chlorinated polyvinyl chloride which is a polymer of hydrocarbon. CPVC is light weight, non-toxic, high mechanical properties and has low friction and low thermal concavity.
