1. Product Overview
The NIBCO 5807 90-degree elbow pipe fitting is constructed from acrylonitrile butadiene styrene (ABS) and is designed for use in drain, waste, and vent (DWV) systems. This fitting features hub connections, allowing it to slide over the ends of male pipes. Its primary function is to change the direction of flow between two pipes at a 90-degree angle.
Key features of this NIBCO ABS elbow include:
- 90-degree elbow: For connecting two pipes or fittings at an angle.
- Hub ends: Designed for connecting to male unthreaded pipes or fittings.
- ABS-DWV material: Provides chemical and corrosion resistance, performs across a wide temperature range, and is lightweight for quick assembly.
- Smooth interior finish: Reduces friction and inhibits material buildup, ensuring superior flow.
- Certified quality: Meets ASTM D2661 and D3311 specifications for quality assurance.

2. Installation and Usage
The NIBCO 90-degree ABS elbow is intended for use in non-pressure residential and commercial drain, waste, and vent (DWV) sanitary systems. ABS material is resistant to most household chemicals and many corrosive industrial liquids, performing well across a wide temperature range. Its lightweight nature simplifies installation both above and below ground.
Installation Guidelines:
- Ensure all pipe ends are clean and free of burrs before assembly.
- Apply an appropriate ABS solvent cement to both the pipe end and the fitting's hub.
- Insert the pipe fully into the fitting's hub with a quarter turn to ensure even distribution of cement.
- Hold the joint firmly for approximately 30 seconds to allow initial set.
- Allow adequate cure time before testing the system, as per solvent cement manufacturer's instructions.
- ABS can be connected to other materials like steel, copper, or cast iron using appropriate transition fittings.

3. Operating Principles
The NIBCO 90 Degree ABS Elbow is a passive component within a plumbing system. Its operation is based on its fixed 90-degree angle, which redirects the flow of waste, drain, or vent gases within the DWV system. Once properly installed and sealed, it provides a permanent, leak-free directional change without requiring any active user interaction or power.
4. Maintenance
Due to the durable nature of ABS material and the static function of the elbow, minimal maintenance is required. Regular inspection of the plumbing system for any signs of leaks or damage around the fitting is recommended. If a leak is detected, the joint may need to be re-cemented or the fitting replaced. Avoid exposing the fitting to chemicals not compatible with ABS, as this could compromise its integrity.
5. Troubleshooting
Most issues related to pipe fittings stem from improper installation. Common troubleshooting scenarios include:
- Leaks at the joint: This typically indicates insufficient solvent cement application, improper pipe insertion, or inadequate cure time. The joint may need to be cut out and re-installed.
- Restricted flow: While rare for the elbow itself, blockages can occur in the system. Ensure proper pipe sizing and slope during installation to prevent debris accumulation.
- Cracks or damage: Physical impact or exposure to incompatible chemicals can cause damage. The fitting must be replaced if cracked or otherwise compromised.
For persistent issues, consult a qualified plumbing professional.
