PVC (AKA: Poly Vinyl Chloride) is the white colored plastic piping used for drainage, vents and various utility applications that do not require pressure ratings. The piping is available from 3/4" though 8" in some applications larger sizes are available but are for industry specific applications. PVC utilizes a solvent weld type system to attach fittings to the pipe. PVC is not compatible with CPVC piping systems.

Some people believe that PVC is suitable for cold water supply line applications, but (aside from local building codes, etc) we don't recommend mixing and matching PVC with CPVC in any supply line plumbing application.
