4. Setup and Installation
The Viega ProPress system simplifies the connection of pipes. Follow these general steps for installation:
- Prepare Pipe Ends: Ensure pipe ends are clean, deburred, and free of any sharp edges or debris.
- Mark Insertion Depth: Use a depth gauge or marking tool to mark the correct insertion depth on the pipe.
- Insert Pipe: Fully insert the pipe into the ProPress fitting until it reaches the marked depth.
- Position Press Tool: Place the jaws of the Viega ProPress tool squarely over the fitting.
- Initiate Press Cycle: Activate the press tool to complete the connection. The tool will cycle automatically.
- Verify Connection: After pressing, visually inspect the connection. The Smart Connect feature will indicate any unpressed connections during system pressure testing.
For detailed instructions specific to your ProPress tool and pipe material, always refer to the official Viega ProPress installation guide.
5. Operation
Once properly installed, the Viega ProPress Bronze Union forms a permanent, watertight seal. The fitting itself does not require active operation beyond its initial installation. Its function is to provide a secure and leak-free connection within the plumbing system. The integrity of the connection is maintained by the pressed joint.
6. Maintenance
Viega ProPress fittings are designed for long-term, maintenance-free operation once correctly installed. Regular maintenance of the overall plumbing system is recommended, including periodic inspection for leaks or signs of wear on pipes and other components. No specific maintenance is required for the ProPress union itself.
7. Troubleshooting
The Smart Connect feature is designed to assist in troubleshooting during the initial pressure test. If a leak is detected:
- Unpressed Connection: The Smart Connect feature will allow water to pass through an unpressed connection during testing, indicating that the fitting was not properly pressed. Re-press the connection with the appropriate tool.
- Improper Pipe Preparation: Ensure pipe ends were clean, deburred, and fully inserted into the fitting.
- Tool Malfunction: Verify that the press tool is functioning correctly and that the jaws are properly calibrated and maintained.
If issues persist, consult the official Viega ProPress technical documentation or contact Viega technical support.
