Five Types of Pipes Used in Plumbing

Plumbing supplies are used for domestic and commercial plumbing applications. There are several different types of plumbing pipes, all of which have their own benefits and drawbacks. Therefore, before selecting a pipe for your particular plumbing project, it is important to know the different kinds of pipes available in the market. Here are five types of pipes that you should be aware of:

Plumbing Pipes

Copper Pipe

Copper piping is the first choice because it is rigid, non-combustible, and resistant to corrosion. It comes in lengths of up to 12 feet and can be joined with fittings, soldering, or compression joints. Although copper resists corrosion well when constantly supplied with water, it does corrode when exposed to air or soil for extended periods of time. Copper pipe begins to corrode as soon as it has been installed and exposed to air or soil.


PVC is a durable and inexpensive plastic pipe that is used for many different plumbing, water supply, and drainage projects. It is most commonly used in commercial buildings and houses with newer plumbing systems. PVC is resistant to corrosion and chemicals. This type of pipe will come in many different schedules (wall thicknesses). Depending on your planned use, it will be important to choose the appropriate schedule for the job.


PEX is short for cross-linked polyethylene. This type of plastic tubing was developed as an alternative to copper tubing in the 1980s. PEX has undergone some changes since it was first introduced and now comes in different formulations such as PEX-A, PEX-B, or PEX-C. Each formulation has different performance characteristics, but all are flexible, durable, and easy to install. This type of tubing resists corrosion, abrasion, and freeze-breakage. It is also able to withstand high temperatures (up to 200 degrees Fahrenheit) and pressures (up to 150 psi).


This type of pipe is used more often in outdoor plumbing applications, like irrigation systems and swimming pools. The biggest benefit that polyethylene offers over other types of pipes is its flexibility. It’s easy to work with & easy to install, making it a popular choice for many homeowners. Polyethylene is a durable material that can withstand the effects of weathering and corrosion. However, it’s vulnerable to damage from ultraviolet rays, which means it will eventually wear out when exposed to sunlight over time.

Galvanized Steel

This is arguably the most prevalent type of steel pipe. It is capable of delivering both cold and hot water, as well as trash. This type of piping has a long history dating all the way back to the nineteenth century, which means it has a strong track record for longevity and durability. The only downside with this kind of pipe is that it has a tendency to corrode over time if it’s exposed to chemicals from harsh cleaning agents or minerals from hard water.
