Introduction:

When working with plumbing, it’s not uncommon to encounter different types of piping materials. More often than not, you may need to connect Pex piping to copper for various reasons in your home or construction project. In this article, we will explore three ways to effectively connect Pex tubing to copper pipes.

1. SharkBite Push-to-Connect Fittings:

One of the most user-friendly and popular connections used in plumbing is the push-to-connect fitting by SharkBite. These fittings can be found at most local hardware stores and are compatible with both Pex and copper pipes.
To use this type of fitting, simply follow these steps:
a. Cut both the Pex and copper pipes cleanly and evenly.
b. Deburr and clean the edges of the pipes.
c. Ensure that both pipes have a matching diameter.
d. Attach the SharkBite push-to-connect fitting on one side.
e. Push the other pipe end into the available opening of the fitting, ensuring it goes in smoothly and securely.

2. Brass Compression Fittings:

Another tried-and-true method of connecting Pex piping to copper is by using brass compression fittings. This method requires a few more steps but creates a strong connection.
To implement this method, follow these steps:
a. Cut both the Pex and copper pipes evenly and cleanly.
b. Deburr and clean the pipe edges.
c. Slide a compression nut onto each pipe end.
d. Place a brass ferrule over each pipe end.
e. Align both pipe ends together with the help of a brass compression fitting connector.
f. Tighten both compression nuts onto each pipe end, making sure to create a secure connection without overtightening.

3. Soldered Copper Connections with Threaded Adapter:

The last method for connecting Pex to copper pipes is by soldering a copper connection with a threaded adapter in place. This method involves heating the pipes, so be cautious and wear appropriate safety gear.
To perform a soldered connection, follow these steps:
a. Cut both the Pex and copper pipes cleanly.
b. Deburr and clean the pipe edges.
c. Attach a threaded adapter (usually a female thread) to the copper pipe using a soldering technique.
d. Mount a corresponding male threaded adapter to the Pex tubing with Pex clamps or rings.
e. Screw both threaded adapters together tightly, forming a secure connection.

Conclusion:

Each of these methods can effectively connect Pex tubing to copper piping, ensuring a safe and secure plumbing system in your home or project site. Be sure to take the necessary precautions and follow steps carefully, depending on your preferred method. Happy plumbing!
