Introduction to Home Plumbing Materials
A home plumbing system will have different types of piping materials for different types of use such as domestic water supply, waste drainage, appliances, irrigation and so on. Being able to identify the type of piping material you have is important but can sometimes be confusing.

Some plastic pipe used in plumbing (such as PVC and CPVC) may also be used in the venting of high efficiency condensing furnaces. However, in this tutorial I will focus on piping use in plumbing applications. I'll outline the most common types of plumbing piping materials found in homes of different ages, what they are used for and how to cut and fasten them together. We will look at the following types of plumbing materials used in piping for waste lines, water supply and natural gas supply:

  • Waste Line: Cast Iron
  • Waste Line: PVC (Poly Vinyl Chloride)
  • Waste Line: Chromed Brass
  • Water Supply: Chromed Copper
  • Water Supply: Galvanized Iron
  • Water Supply: Copper (rigid and flexible)
  • Water Supply: CPVC (Chlorinated Poly Vinyl Chloride)
  • Water Supply: PEX (Cross-linked Polyethylene)
  • Gas: Black Iron
