How to Tee Off PEX Pipe in 5 Easy Steps: Avoid Costly Leaks
What To Know
- Place a PEX crimp ring on each end of the tee where it connects to the PEX pipe.
- The size of the PEX tee should match the diameter of the PEX pipe being used.
- Ensure that the PEX pipe is cut squarely, the crimp rings are tightened properly, and the tee is secured tightly.
PEX (cross-linked polyethylene) pipes are becoming increasingly popular in plumbing due to their flexibility, durability, and ease of installation. However, when it comes to branching off from a main PEX line, homeowners often wonder how to tee off PEX pipe. This guide will provide a step-by-step walkthrough of the process, ensuring a secure and professional-looking connection.
Materials Required
- PEX pipe
- PEX tees
- PEX pipe cutter
- Crimp tool
- PEX crimp rings
- Plumber’s tape
Step 1: Cut the PEX Pipe
Measure and mark the desired location for the tee on the main PEX line. Use a PEX pipe cutter to make a clean and square cut.
Step 2: Insert the PEX Tee
Insert the PEX tee into the cut pipe. Ensure that the barbs on the tee are facing the correct direction.
Step 3: Tighten the Crimp Rings
Place a PEX crimp ring on each end of the tee where it connects to the PEX pipe. Use a crimp tool to tighten the crimp rings, ensuring a secure seal.
Step 4: Install the Branch Pipe
Cut a piece of PEX pipe to the desired length for the branch line. Insert the pipe into the remaining opening on the tee.
Step 5: Crimp the Branch Line
Insert a PEX crimp ring onto the branch pipe and tighten it using the crimp tool.
Step 6: Secure the Tee
Wrap plumber’s tape around the threads on the tee. Screw the tee into the appropriate fitting or valve.
Step 7: Pressure Test
Once all connections are made, turn on the water supply and check for any leaks. If there are no leaks, the tee is properly installed.
Troubleshooting Tips
- If the PEX pipe is not cut squarely, it may not fit properly into the tee.
- If the crimp rings are not tightened properly, the connection may leak.
- If the tee is not secured properly, it may come loose and cause a leak.
Summary: Teeing Off PEX Pipe Made Easy
Teeing off PEX pipe is a relatively simple process that can be completed by most DIY enthusiasts. By following these steps, you can ensure a secure and leak-free connection. Remember to use high-quality materials and follow the manufacturer’s instructions for best results.
