Charlotte Pipe & Foundry PVC DWV Street Elbow User Manual

1. Product Overview

This manual provides essential information for the proper installation and use of the Charlotte Pipe & Foundry PVC DWV Street Elbow. This fitting is designed for use in Drain, Waste, and Vent (DWV) systems.

The PVC DWV Street Elbow is a durable, corrosion-resistant fitting used to change the direction of piping in a DWV system by 22.5 degrees. Its "street" design means one end is spigot (male) and the other is hub (female), allowing it to fit directly into another fitting's hub without needing an additional coupling.

2. Setup and Installation

Proper installation is crucial for the long-term performance of your DWV system. Always consult local plumbing codes and regulations before beginning any installation.

2.1. Safety Precautions

• Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
• Ensure the work area is well-ventilated when using PVC primer and cement.
• Keep all chemicals away from open flames or heat sources.

2.2. Required Tools and Materials

• PVC pipe cutter or hacksaw
• Deburring tool or sandpaper
• Measuring tape
• Marker
• PVC primer (purple or clear)
• PVC cement (medium or heavy duty)
• Clean rags

2.3. Installation Steps

1. Measure and Cut: Measure the required length of PVC pipe. Cut the pipe squarely using a PVC pipe cutter or hacksaw.
2. Deburr: Remove any burrs or rough edges from the inside and outside of the cut pipe using a deburring tool or sandpaper. This ensures proper flow and a secure connection.
3. Dry Fit: Temporarily fit the elbow onto the pipe and into the receiving fitting (if applicable) to ensure proper alignment and fit. Mark the pipe and fitting for alignment.
4. Apply Primer: Apply a liberal coat of PVC primer to the outside of the pipe end and the inside of the elbow's hub. The primer softens the PVC surface for better solvent welding.
5. Apply Cement: While the primer is still wet, apply a uniform, heavy coat of PVC cement to the primed pipe end and a medium coat to the primed inside of the elbow's hub.
6. Join Components: Immediately insert the pipe into the elbow's hub, twisting the pipe a quarter turn to distribute the cement evenly. Hold the connection firmly for at least 30 seconds to allow the cement to set.
7. Wipe Excess: Wipe off any excess cement from the joint with a clean rag.
8. Cure Time: Allow the joint to cure according to the PVC cement manufacturer's recommendations before putting the system into service. This typically ranges from 30 minutes to 24 hours depending on temperature and pipe size.

3. Operating Considerations

The Charlotte Pipe & Foundry PVC DWV Street Elbow is designed for non-pressure drain, waste, and vent applications. It is not intended for use with pressurized systems or for conveying potable water.

• Ensure proper slope for gravity drainage in DWV systems.
• Avoid exposing PVC fittings to direct sunlight for extended periods, as UV radiation can degrade the material over time.
• Do not use PVC fittings with compressed air or gas systems.

4. Maintenance

PVC DWV fittings are generally maintenance-free once properly installed. However, periodic inspection of your plumbing system is recommended.

• Inspect visible joints for any signs of leaks or damage.
• Ensure that pipes are properly supported to prevent stress on fittings.
• Avoid pouring harsh chemicals or solvents down drains that could degrade PVC.

5. Troubleshooting

Most issues with PVC DWV fittings arise from improper installation.

5.1. Leaks at Joints

• Cause: Insufficient primer/cement, improper application, or insufficient cure time.
• Solution: The leaking joint must be cut out and replaced with new pipe and fittings, ensuring proper priming, cementing, and cure time.

5.2. Fitting Does Not Seat Properly

• Cause: Burrs on pipe end, pipe not cut squarely, or incorrect pipe size.
• Solution: Ensure pipe ends are deburred and cut squarely. Verify that the pipe diameter matches the fitting size (e.g., 4-inch pipe for a 4-inch fitting).
