A Guide to PEX Piping: What You Need to Know

plumbing tools, updating pex pipes in home plumbing

Cross-linked polyethylene, also known as PEX piping, has become a popular choice for plumbing around the world. It’s lightweight, a great insulator, and easy to work with, making it a favorite for both professionals and DIYers. Though the technology behind PEX was discovered in the 1930s, it wasn’t widely used until the 1970s, when production costs dropped. Today, PEX is the second most commonly used piping material, right behind copper tubing.

If you’re considering replacing your PEX piping, here’s a basic guide to help you through the process.

Key Takeaways

  • PEX piping is lightweight, easy to work with, and widely used in modern plumbing.
  • Before replacing PEX, make sure you have the right tools, including a pipe cutter and PEX clamp tool.
  • If DIY plumbing goes wrong, it’s best to call in professionals to ensure the job is done correctly.

Let’s walk through the steps for replacing PEX piping.

Pipe Replacement 101: The Basics

Before you start, make sure you’re working with PEX piping. You can easily identify it by the PEX label on the side of the pipe. Once confirmed, gather the following tools:

  • Pipe cutter
  • PEX clamp tool
  • Tape measure

Also, double-check that the replacement PEX tubing is the correct size for your project.

Step 1: Shut Off the Water

Before you begin cutting into your piping, turn off the water mains and release the pressure in the pipe by running the faucet. This ensures that no water is left in the pipe you’re working on, preventing potential messes.

Step 2: Cut the Old PEX Pipe

Using your pipe cutter, carefully cut the old PEX piping below the area that’s leaking or damaged. Measure the length of the replacement piping you’ll need using your tape measure. You can mark the pipe with a sharpie to ensure you cut the right length.

Step 3: Attach the Fittings

Once your replacement pipe is cut to the correct length, it’s time to attach the fittings. Insert the new pipe into the fittings and use your PEX clamp tool to secure them. If everything is positioned correctly, you should have a newly installed pipe that’s ready to provide free-flowing, efficient plumbing.
