7 Various Types of Sewer Pipes

Plumber Parramatta

For easy repairs on your pipes, you must be able to classify the different types of pipes. The first two types discussed below, clay and cast iron sewer pipes, may not be familiar to you since these two are old versions of a pipe. PVC, ABS and copper are the most commonly used pipes today. Listed below are the 7 various types of sewer pipes.


      Vitrified clay sewer pipe is still established these days. This type of sewer pipe is quite heavy and tough to cut. So I guess you won’t consider this as a replacement to your damaged pipe. Clay pipe is made of inert. It makes clay pipes to be hardly resistant to chemical deterioration. The negative side of using this type of sewer pipe is that it attracts roots to stick the pipe’s porous surface.

    Cast Iron

      This type is usually installed to older but this is still available for installation these days. Cast -iron sewer pipe is astonishingly firm since it is a 4” sewer pipe and can handle up to 4,877 pounds of pressure per linear foot. Just like a clay sewer pipe, you’ll be needing a plumber to cut it since it is heavy and difficult to cut. I believe a DIYer can’t handle the heaviness of these two types of pipes.

    Plastic: PVC and ABS

      Plastic sewer pipes are for underground installment. It is available in two types: PVC and ABS. The two types have a smooth interior suitable for carrying accommodation for matters such as solid waste. The smooth exteriors of these types are also an aid to repel root anchorage. These types are commonly used in pipes since it is non – toxic and can resist to scratches. Below shows the difference between the two types:

      • PVC (polyvinyl chloride) is flexible but a durable type of pipe. It can be availed at a very affordable cost. This commonly used in cable insulation, pipes, toys or even clothes.
      • ABS (Acrylonitrile Butadiene Styrene) can also be bought at a cheaper price. This is typically used in instruments, toys, pipes, luggage, appliances and canoes. This type has a rigid and tough property. ABS is easier to install compared to PVC.


      Orangeburg sewer pipe, also known as fibre conduit pipe, is typically made of wood. This sewer pipe is made of ground cellulose fibres coerced as a group plus special water defiant. This is also saturated with liquefied coal tar pitch.

    PEX (cross-linked polyethylene)

      PEX is the advanced pipe for residential use. PEX is easy to install since it is easy to cut and also flexible. It also uses compression fittings. The negative side of this type is, it costs twice than copper or plastic.


      Steel pipes are commonly used in older homes. Galvanised steel pipes are but can last for a maximum of 50 years. Instead of replacing it, you can just have a professional to repair it first.


      Copper pipes are commonly used in water supply lines by most homeowners since it can resist to corrosion. It can last long and is as affordable as plastic does. Listed below are the two types of copper pipe:

      • Rigid Copper consists of three types: The thinnest but is also strong for most homes, Type M. Type L and K are both used in outdoor and drain applications. In cutting a rigid copper, you will need a tube cutter, wheel cutter, or maybe a hacksaw. Pipes are commonly linked with a soldered fitting and the compression fitting could be linked to the pipe to shut-off valves.
      • Flexible Copper is typically used for refrigerator, dishwasher, icemaker and appliances that require water supply. This is easy to bend but once it kinks, you should cut off the piece and replace it. Its sections can be linked by the use of soldered fitting or compression fitting.
