Components and Features
The Viega Propress 90 Drop Ear Elbow (Model 79185) is a high-quality plumbing fitting characterized by:
- Propress Technology: Enables fast, flameless, and secure connections.
- 90-Degree Bend: Ideal for changing pipe direction in tight spaces.
- Drop Ear Design: Features an integrated mounting tab with holes for secure attachment to structural elements, preventing pipe movement and reducing stress on connections.
- Zero Lead Material: Constructed from lead-free material, making it suitable for potable water applications and compliant with relevant health standards.
- EPDM Sealing Element: Equipped with a durable EPDM sealing element for reliable, leak-proof connections.
Setup and Installation
Follow these steps for a successful Viega Propress connection:
- Pipe Preparation:
- Cut the pipe squarely to the desired length.
- Deburr the inside and outside of the pipe end to remove any sharp edges or burrs.
- Clean the pipe end thoroughly to remove any dirt, grease, or debris.
- Fitting Insertion:
- Ensure the sealing element is properly seated within the fitting.
- Insert the prepared pipe end fully into the Propress fitting until it reaches the pipe stop. Verify that the pipe is visible through the inspection hole (if present) to confirm full insertion.
- Pressing:
- Open the jaws of the Viega Propress tool and place them squarely over the fitting's bead.
- Activate the pressing tool. The tool will cycle automatically, pressing the fitting onto the pipe.
- Once the pressing cycle is complete, the tool will release. Remove the tool from the fitting.
- Visual Inspection:
- Visually inspect the pressed connection to ensure the fitting is properly crimped and the pipe is securely joined.
- Mounting (Drop Ear):
- Secure the drop ear tab to a suitable structural element using appropriate fasteners (not included) to provide stability and support for the piping.
Functionality and Post-Installation Check
Once installed, the Viega Propress 90 Drop Ear Elbow functions as a permanent, leak-proof connection within your plumbing system. After installation, it is crucial to perform a system pressure test to confirm the integrity of all connections before putting the system into full operation.
- Pressure Testing: Gradually pressurize the system to the recommended operating pressure.
- Leak Detection: Carefully inspect all connections for any signs of leaks. Address any leaks immediately by depressurizing the system and re-pressing the fitting if necessary, or replacing it if damaged.
Maintenance
Viega Propress fittings are designed for long-term, maintenance-free operation once properly installed. However, regular inspection of your plumbing system is recommended:
- Periodic Visual Inspection: Periodically check all visible connections for any signs of corrosion, damage, or leaks.
- System Health: Ensure the overall plumbing system is operating within its design parameters (e.g., pressure, temperature) to prevent undue stress on fittings.
Troubleshooting
Most issues with Propress fittings arise from improper installation. If a leak occurs:
- Leak at Connection:
- Cause: Improper pipe preparation (not deburred, dirty), incomplete pipe insertion, or incorrect pressing tool/jaws.
- Solution: Depressurize the system. If the fitting was not fully pressed, it may be possible to re-press it with the correct tool. If the pipe was not fully inserted or damaged, the fitting and potentially the pipe section may need to be replaced. Always ensure proper pipe preparation and full insertion.
- Damaged Fitting:
- Cause: Physical impact, excessive stress, or incorrect handling.
- Solution: Depressurize the system and replace the damaged fitting.
For persistent issues, contact a qualified plumbing professional.
