How to Install a Shower Valve with PEX- A Step-by-Step Guide for a Successful DIY Project
How to Install a Shower Valve with PEX
Installing a shower valve with PEX (Cross-Linked Polyethylene) piping is a modern and efficient way to update your bathroom. PEX is a flexible, durable, and easy-to-install piping material that offers numerous benefits over traditional copper or CPVC piping. In this article, we will guide you through the step-by-step process of installing a shower valve with PEX, ensuring a successful and leak-free installation.
Materials and Tools Needed
Before you begin the installation, gather the following materials and tools:
– PEX piping (copper or PEX-a)
– PEX crimp rings and crimp tools
– PEX compression fittings (for copper piping)
– Shower valve and handles
– Teflon tape
– Adjustable wrench
– PEX cutter or saw
– PEX crimper
– PEX glue (if using PEX-a piping)
– Plumbing tape
– Threaded connectors (if using copper piping)
– Threaded nipples (if using copper piping)
Step 1: Turn Off the Water Supply
Before starting the installation, ensure that the water supply to the shower is turned off. This will prevent any water from escaping during the installation process.
Step 2: Remove the Old Shower Valve
If you are replacing an existing shower valve, remove it by unscrewing the mounting nuts and disconnecting the water supply lines. Be sure to keep track of the parts and order them if necessary.
Step 3: Install the New Shower Valve
Attach the new shower valve to the wall according to the manufacturer’s instructions. Ensure that the valve is securely mounted and that the handles are in the correct position.
Step 4: Cut the PEX Piping
Measure the distance between the shower valve and the water supply lines, and cut the PEX piping to the appropriate length. Use a PEX cutter or saw to make a clean, straight cut.
Step 5: Attach the PEX Piping to the Shower Valve
For copper piping, use PEX compression fittings. Slide the PEX piping into the compression fitting, then place the crimp ring over the piping and fitting. Use the crimp tool to crimp the ring securely in place. For PEX-a piping, use PEX glue to attach the piping to the compression fitting.
For PEX piping, use PEX crimp rings and crimp tools. Slide the PEX piping into the crimp ring, then place the crimp ring over the piping and fitting. Use the crimp tool to crimp the ring securely in place.
Step 6: Connect the Water Supply Lines
Attach the water supply lines to the shower valve using the appropriate connectors and fittings. For copper piping, use threaded connectors and nipples. For PEX piping, use PEX crimp rings and crimp tools.
Step 7: Test the Installation
Turn the water supply back on and check for leaks at all connections. If there are no leaks, the installation is complete.
Step 8: Finishing Touches
Install the showerhead and any additional accessories, such as a hand shower or body sprays. Adjust the water pressure and temperature to ensure they are comfortable and consistent.
By following these steps, you can successfully install a shower valve with PEX piping, providing a durable and efficient solution for your bathroom. Always remember to consult a professional plumber if you are unsure about any aspect of the installation process.
