Pex plumbing: All you need to know

Pex plumbing is a type of plumbing system that uses cross-linked polyethylene (PEX) tubing instead of traditional metal piping. This type of tubing offers a variety of advantages, including increased flexibility and durability, cost savings, and easier installation compared to other types of pipe. In this article, we’ll take a look at all you need to know about the installation and maintenance of a Pex plumbing system.

Benefits of Using Pex Plumbing

The biggest advantage of using Pex plumbing is its increased flexibility. Unlike rigid metal pipes, which must be run in straight lines and can take up a lot of space, PEX tubing can bend around corners and fit into smaller spaces. This makes it ideal for tight or awkward installation spots.

Pex plumbing also offers two major advantages in terms of cost savings and durability. The tubing is constructed from resistant materials such as PEX-A, PEX-B, and PEX-C. This makes it resistant to corrosion and abrasion, which means that it will last longer than traditional metal pipes. Additionally, since Pex plumbing is cheaper and easier to install, it can save you money in the long run.


Installing a Pex plumbing system does not require special tools or knowledge; most of the components are easy to use and will fit together without much effort. The process begins with cutting the tubing into the desired lengths, typically with a tubing cutter. After this is done, you’ll need to attach the fittings to the tubing: brass or plastic compression fittings are generally used for Pex plumbing installations.

The next step is to do the pex piping – connect the pipes and valves needed for your system. You will then need to test your installation by turning on all of the valves and ensuring that everything is working properly. Finally, once the installation is complete, you can insulate the pipes to reduce heat loss or noise from running water.


Just like any other type of plumbing system, Pex plumbing requires regular maintenance in order to keep it functioning properly. This includes inspecting all joints and fittings for signs of corrosion or leaks, as well as checking for any loose connections. Additionally, it’s important to regularly check the pressure in the system, since a drop in pressure can indicate a leak somewhere in the system.

In terms of cleaning your Pex plumbing system, you should avoid using harsh chemicals that could corrode or damage the tubing. Instead, use a mild cleaner and some warm water to rid the pipes of any buildup of sediment or other debris.

Overall, Pex plumbing is a great choice for anyone looking for an efficient and cost-effective way to install their plumbing system. With its increased flexibility and durability, as well as ease of installation and maintenance, Pex plumbing is sure to be a wise investment.


Pex plumbing offers many advantages over traditional metal piping, including flexibility, cost savings and easier installation and maintenance. If you are looking for a reliable system that will provide long-lasting performance without requiring any special tools or knowledge, then Pex plumbing is definitely worth considering. Now that you know all about the installation and maintenance of a Pex plumbing system, you’ll be ready to get started on your own project. Good luck!
