PEX is an innovative, sturdy plastic tubing that has taken the plumbing world by storm. Crafted from high-density polyethylene and boasting impressive flexibility, these pipes are ideal for a wide array of applications. From water supply lines to radiant floor heating tubes, PEX is quickly becoming the go-to choice for all kinds of projects.

When it comes to plumbing, PEX tubing is the optimal choice. This cross-linked polyethylene piping offers an affordable and non-corrosive solution that outperforms copper or galvanized pipe options in terms of cost and longevity. Not only that, but its immunity to wear and tear makes this a hugely popular pick for all types of applications.

PEX VS.Copper

When it comes to choosing between PEX vs. copper pipes, the choice largely depends on your specific needs and budget. Copper is a tried-and-true plumbing material that has been used for years, but it’s becoming increasingly less common as the cost of PEX continues to decrease.

On the other hand, PEX pipes are highly flexible and resistant to corrosion, making them a top choice for radiant floor heating systems or cold water supply lines in new construction. Copper, while still a popular choice for some projects, is more prone to leaks and corrosion over time, so for most homeowners and professionals, PEX is the better option.

Ultimately, it’s important to weigh the pros and cons of both PEX and copper pipes when making your decision. Whether you decide to go with PEX or copper, there’s no denying that both options will help you get the job done quickly and effectively.

By taking a few straightforward steps and utilizing simple tools, you can quickly and easily connect PEX to your faucet with no hassle.

Materials & Tools Needed

To connect PEX to a faucet, you will need to gather the following supplies and tools:

  • Two pieces of 1/2 inch PEX piping, appropriate length
  • PEX pipe cutter
  • Two 1/2 inch x 1/2 inch PEX faucet connectors
  • Two crimp rings
  • Basin wrench
  • Crimping tool


Step 1: Cut the PEX Pipe

First, you will need to cut the PEX pipe so that it is the right length for your project. To do this, use a PEX pipe cutter or a sharp utility knife to carefully cut the pipe to the desired length.

Step 2: Crimp the Fitting

Once you have cut your PEX pipe to the right length, slide a crimp ring onto both pieces and fit each end with a barbed connector until it is completely inserted.

Place the crimp ring at the very tip of these pipes, making sure that it covers up the barb connection tightly before clamping down with your tool’s handles to ensure a secure connection.

Step 3: Connect to the Faucet

Once your PEX pipe is connected to the faucet, you can slide your newly-made connection into place. If necessary, tighten the connection with a wrench or pliers to ensure that it is secure and won’t leak.

Step 4: Check for Leaks

To finish up double, check your PEX connection by turning on the water supply, and look for any indications of leaking. After you’re satisfied that all fittings are up to standard, switch on the faucet and examine for any leaks.

If a threaded nut is where the leak occurs, give it an additional 1/2 twist with a basin wrench to seal off the gap.

Frequently Asked Questions

When should you not use PEX?

PEX is a highly versatile material and can be used in many different applications. No matter the temperature, PEX plumbing is great for use indoors and can always be insulated. Unfortunately, though, its usage outdoors in cold climates isn’t as successful due to there being no way of protecting it from freezing temperatures.

Do PEX fittings ever leak?

Unlike conventional pipes, PEX is nearly leak-proof. Plumbing leaks tend to occur at the connection points, often because of improper installation. Fortunately, PEX tubing is just as simple to repair as it was to install.

Is PEX crimp or clamp better?

There is no right or wrong answer when it comes to crimp versus clamp fittings for PEX. Crimping is generally the preferred method as it provides a more secure connection, but clamps may be a better choice for some applications.

Ultimately, the best method will depend on factors such as the type of PEX tubing being used, the conditions of your project, and your personal preferences. As always, it is important to consult with a professional before making any decisions about your PEX plumbing.

Do rodents chew on PEX?

Although rodents are unlikely to bite into PEX tubing, they can be attracted to the insulation surrounding it or any other materials connected with it. If you fear that these critters may damage your plumbing, then keep an ear out for rustling noises coming from your attic as a sign of their presence.

Do I need a special tool to crimp PEX?

In most cases, you will need a special PEX crimping tool to properly connect and secure PEX fittings. However, there are a few alternative methods that can also be used, such as using a pair of pliers and a PEX clamp or simply hand-tightening the fittings.


PEX is a versatile material that can be used for a wide range of plumbing applications, from water supply lines to radiant floor heating systems. While it may require some special tools and fittings to connect to a faucet, it is generally considered an easy and effective option for DIYers and professionals alike.

Whether you are a homeowner looking to tackle a small plumbing project on your own or a professional contractor working on a larger job, PEX is an affordable and durable material that will get the job done efficiently and effectively.

However, it is important to make sure that all of your fittings are secure and free from leaks in order to prevent any water damage or other issues down the line.
