Transform your bathroom: install a new shower faucet with pex, no solder required!

Installing a shower faucet with PEX tubing is a relatively straightforward task that can be completed in a few hours with the right tools and materials. Follow this step-by-step guide to ensure a successful installation.

Tools and Materials You’ll Need:

• Adjustable wrench
• PEX cutter
• PEX crimp tool
• PEX crimping rings
• PEX expander tool (for PEX-A tubing)
• PEX inserts (for PEX-B and PEX-C tubing)
• Shower faucet
• Teflon tape
• Plumber’s putty

Step-by-Step Instructions:

1. Shut Off the Water Supply

Turn off the main water supply to your home or apartment. This is typically located in the basement, garage, or utility closet.

2. Remove the Old Shower Faucet

Using an adjustable wrench, loosen the nuts that hold the old shower faucet in place. Carefully remove the faucet and any remaining hardware.

3. Prepare the PEX Tubing

Cut the PEX tubing to the desired length using a PEX cutter. Ensure the cuts are clean and square.

4. Insert PEX Inserts (for PEX-B and PEX-C)

If you’re using PEX-B or PEX-C tubing, insert a PEX insert into each end of the tubing. This will help prevent the tubing from collapsing when crimped.

5. Expand the PEX Tubing (for PEX-A)

If you’re using PEX-A tubing, use a PEX expander tool to expand the ends of the tubing. This will create a flared opening that will allow the crimping ring to fit properly.

6. Attach the Crimping Rings

Slide a PEX crimping ring onto each end of the tubing. Ensure the ring is positioned correctly over the expanded or inserted tubing.

7. Crimp the PEX Tubing

Using a PEX crimp tool, crimp the rings onto the tubing. This will create a permanent, watertight connection.

8. Install the Shower Faucet

Apply Teflon tape to the threads of the shower faucet’s mounting nuts. Thread the nuts onto the PEX tubing and hand-tighten them.

9. Secure the Shower Faucet

Using an adjustable wrench, tighten the mounting nuts securely. Ensure the faucet is level and stable.

10. Apply Plumber’s Putty

Roll out a small piece of plumber’s putty into a rope. Place the putty around the base of the faucet, where it meets the shower wall. This will help seal any gaps and prevent leaks.

11. Turn On the Water Supply

Slowly turn on the main water supply and check for any leaks. If you notice any leaks, tighten the connections or adjust the plumber’s putty accordingly.

Tips for Success:

• Use the correct type of PEX tubing for your application.
• Cut the tubing cleanly and squarely.
• Expand or insert the tubing properly before crimping.
• Crimp the rings securely using the appropriate tool.
• Apply Teflon tape to all threaded connections.
• Use plumber’s putty to seal any gaps around the faucet.

Troubleshooting:

• Leaking from the faucet: Tighten the mounting nuts or adjust the plumber’s putty.
• Leaking from the PEX connections: Recrimp the rings or replace the PEX tubing if necessary.
• Faucet is not level: Adjust the mounting nuts to level the faucet.
• Faucet is loose: Tighten the mounting nuts securely.

Key Points:

Installing a shower faucet with PEX tubing is a relatively simple task that can be completed with basic plumbing tools and materials. By following these step-by-step instructions and tips, you can ensure a successful installation and enjoy a leak-free shower experience.
