PEX (cross-linked polyethylene) tubing has become a popular choice for plumbing projects due to its flexibility, resistance to corrosion, and ease of installation. However, when working with coiled PEX tubing, you may encounter some challenges in getting it to lay flat and run smoothly. This article will guide you through the steps to effectively run coiled PEX tubing, including preparation, installation techniques, and troubleshooting common issues.
PEX tubing is available in various sizes and types (A, B, and C), each with unique properties. It is typically used for water supply lines and radiant heating systems. The flexibility of PEX allows it to be bent around corners without the need for additional fittings, which can save time and reduce potential leak points.
Before you begin running your coiled PEX tubing, it is essential to gather the necessary tools and materials:
- Tools Needed:
- PEX cutter
- Crimping tool or cinch clamp tool
- Go/no-go gauge for crimp connections
- Pipe supports or clamps
- Measuring tape
- Marker
- Materials:
- Coiled PEX tubing
- PEX fittings (crimp or push-fit)
- Crimp rings or cinch clamps
Start by carefully uncoiling the PEX tubing. To prevent kinks:
- Lay the coil flat on the ground.
- Use a helper if necessary to hold one end while you pull from the other end.
- Avoid stretching the tubing too tightly as it can lead to deformation.
Using a measuring tape, determine the length of PEX needed for your installation. Mark the tubing and make a clean cut with a PEX cutter to ensure a straight edge.
Depending on your connection method (crimp or push-fit), follow these steps:
- For Crimp Connections:
- Slide a crimp ring over the end of the tubing.
- Insert the fitting into the tubing until it reaches the shoulder.
- Position the crimp ring about $$ \frac{1}{8} $$ inch from the end of the tubing.
- Use a crimping tool to compress the ring securely around the fitting.
- For Push-Fit Connections:
- Simply push the fitting into the end of the tubing until it clicks into place.
To prevent sagging and ensure proper alignment:
- Use pipe supports or clamps every 16 to 24 inches along horizontal runs.
- For vertical runs, secure at least every four feet.
While PEX is flexible, sharp bends can cause kinks:
- Use bend supports if necessary.
- Avoid using metal straps that can pinch; opt for plastic straps instead.
Once all connections are made, conduct a pressure test:
- Close all fixtures connected to your PEX system.
- Attach a pressure gauge to one end of your system.
- Pressurize to check for leaks at each connection point.
Running coiled PEX tubing can present some challenges. Here are some common issues and their solutions:
- Kinking: If you accidentally kink your PEX, cut out the damaged section and replace it with a new piece.
- Difficulty Uncoiling: If your coil is particularly tight, warm it slightly with a heat gun (on low) to make it more pliable.
- Leaking Connections: If you notice leaks after pressurizing your system, check each connection with a go/no-go gauge to ensure they are crimped correctly.
To further enhance your installation process, consider these additional tips:
Using high-quality tools designed specifically for PEX installation will significantly impact your success. A good quality PEX cutter will provide clean cuts that reduce potential leaks.
When working with PEX in cold environments, it's important to keep it warm before installation. Cold temperatures can make PEX more rigid and difficult to work with.
- You can warm up your coiled tubing by placing it in warm water or running warm water through it before installation[4].
When securing fittings with crimp rings or cinch clamps, avoid over-tightening as this can lead to damage or cracking in both the fittings and tubing[3].
As you install your piping, mark each run at junctions or where they connect to fixtures. This practice helps avoid confusion later on during maintenance or modifications[9].
Even with careful planning and execution, problems may arise during installation. Here are some common mistakes and how to fix them:
- Improper Crimping: If you find that your fittings are leaking after testing, they may not have been crimped properly. Use a go/no-go gauge immediately after crimping to ensure that connections are secure[5][10].
- Incompatible Fittings: Ensure that all fittings used are compatible with your specific type of PEX tubing (A, B, or C). Using mismatched components can lead to leaks or system failures[6].
- Kinking During Installation: If kinks occur while routing your tubing through tight spaces or around corners, consider using bend supports or gradually curving around obstacles instead of making sharp turns[1][2].
Running coiled PEX tubing can be straightforward if you follow proper techniques and take precautions against common pitfalls. With its flexibility and ease of installation, PEX remains an excellent choice for modern plumbing projects.
You will need a PEX cutter, crimping tool or cinch clamp tool, go/no-go gauge, measuring tape, marker, and pipe supports or clamps.
Yes, PEX is flexible and can be bent around corners without additional fittings; however, avoid sharp bends that could kink the tubing.
You can use crimp fittings or push-fit connectors to join PEX tubing with existing plumbing systems.
Support horizontal runs every 16 to 24 inches and vertical runs at least every four feet.
If you find leaks after pressurizing your system, check each connection with a go/no-go gauge and re-crimp any that are not secure.
