SharkBite U850G50 PEX Tubing Instruction Manual

1. Introduction

This manual provides essential information for the proper installation, use, and maintenance of your SharkBite U850G50 PEX Tubing. This cross-linked polyethylene (PEX) tubing is designed for potable water applications. It features a 1/4-inch nominal size (3/8 O.D.) and comes in a 50-foot coil. The tubing is manufactured without an oxygen barrier, making it suitable for standard potable water systems. A repeating SharkBite imprint pattern on the tubing serves as a visual guide to ensure correct insertion depth into SharkBite push-to-connect fittings.

2. Safety Information

Always observe the following safety precautions when working with plumbing systems:

• Turn off water supply: Before beginning any plumbing work, ensure the main water supply is completely shut off to prevent water damage.
• Wear appropriate personal protective equipment (PPE): This includes safety glasses to protect eyes from debris or splashes.
• Depressurize the system: Open faucets to relieve pressure in the water lines after shutting off the main supply.
• Handle tools safely: Use tools as intended and keep hands clear of cutting edges.
• Consult local codes: Always ensure your installation complies with local plumbing and building codes.

3. Setup and Installation

3.1. Preparation

Before starting, ensure you have all necessary tools and materials, including a PEX tubing cutter and appropriate SharkBite push-to-connect fittings.

3.2. Cutting PEX Tubing

Use a specialized PEX tubing cutter to make clean, square cuts. A clean cut is crucial for a secure, leak-free connection with push-to-connect fittings. Avoid using utility knives or saws, as these can create uneven edges or burrs that compromise the seal.

3.3. Connecting to SharkBite Fittings

SharkBite PEX tubing is designed for use with SharkBite push-to-connect fittings. Follow these steps for a secure connection:

1. Cut: Ensure the PEX tubing is cut squarely and free of burrs or debris.
2. Mark: Use the repeating SharkBite imprint pattern on the tubing as a visual guide. Measure the required insertion depth for your specific SharkBite fitting (refer to fitting instructions) and mark the tubing at this depth.
3. Push: Firmly push the tubing into the fitting until it reaches the marked insertion depth. You should feel a slight resistance as the tubing passes through the O-ring and then a firm stop as it engages with the grab ring.
4. Verify: Visually inspect the connection to ensure the tubing is fully inserted to the mark. A properly inserted tube will have the SharkBite imprint pattern fully covered by the fitting.

3.4. Routing and Support

When routing PEX tubing, avoid sharp bends that can cause kinks. Use appropriate hangers or clips to support the tubing at recommended intervals, preventing sagging and stress on connections. Ensure the tubing is not exposed to direct sunlight or UV radiation for extended periods, as this can degrade the material.

4. Operating (System Activation)

Once all connections are made and verified, slowly turn on the main water supply. Carefully inspect all new connections for any signs of leaks. Allow the system to pressurize gradually. The SharkBite U850G50 PEX Tubing is now integrated into your potable water system and will function as part of the water distribution network.

5. Maintenance

SharkBite PEX tubing requires minimal maintenance. Regular inspection is recommended to ensure the longevity and integrity of your plumbing system.

• Periodic Inspection: Periodically check all visible PEX tubing and connections for any signs of leaks, damage, or wear.
• UV Protection: If any portion of the PEX tubing is exposed to direct sunlight, consider shielding it to prevent potential degradation from UV radiation.
• Freezing Prevention: In cold climates, ensure PEX tubing is adequately insulated or protected from freezing temperatures to prevent damage.

6. Troubleshooting

This section addresses common issues that may arise during or after installation.

6.1. Leaks at Connections

• Issue: Water leaking from a SharkBite fitting connection.
• Possible Causes & Solutions:
  • Improper Cut: The tubing end may not be cut squarely or may have burrs. Disconnect the fitting, re-cut the tubing cleanly, and re-insert.
  • Insufficient Insertion: The tubing was not pushed fully into the fitting. Disconnect and re-insert the tubing, ensuring it reaches the proper depth as indicated by the SharkBite imprint pattern.
  • Damaged Tubing: The end of the tubing may be scratched or damaged. Cut off the damaged section and re-connect.
  • Damaged Fitting: Inspect the fitting's O-ring and grab ring for damage. If damaged, replace the fitting.

6.2. Kinked Tubing

• Issue: The PEX tubing has a sharp bend or kink, restricting water flow.
• Possible Causes & Solutions:
  • Over-bending: PEX tubing has a minimum bend radius. Exceeding this radius can cause kinks.
  • Solution: Kinked PEX tubing cannot be repaired effectively. The affected section must be cut out and replaced with a new piece of tubing and appropriate fittings. Plan your tubing runs to avoid sharp turns.
