3 inch PVC DWV 22-1/2 Degree Elbow Plastic x Plastic

3 inch PVC 22-1/2° Elbow – Schedule 40 DWV Fitting for Directional Offsets

The 3 inch PVC 22-1/2° elbow is a solvent-weld drainage fitting designed for directional changes in non-pressurized waste, vent, and drainage (DWV) systems. It enables a gradual offset in the pipeline—commonly used where angular alignment or vertical-to-horizontal transitions require precise directional control without inducing flow restrictions.

Manufactured from Schedule 40 PVC, this elbow is engineered to meet dimensional and performance standards applicable to residential and commercial gravity-fed plumbing systems. Its hub-end connections are compatible with standard 3 inch PVC DWV pipe, providing a permanent joint when properly solvent welded.

Key Product Characteristics

• ✅ 22-1/2° Bend Angle Facilitates gradual directional transitions to reduce turbulence and backpressure in horizontal or vertical runs.
• ✅ Rigid PVC Body Fabricated from Type I, Grade I PVC conforming to ASTM D1784 for corrosion resistance and longevity.
• ✅ Slip Hub Connections Designed for solvent welding with 3 inch nominal PVC pipe (Schedule 40 DWV).
• ✅ Smooth Internal Bore Promotes efficient drainage flow and minimizes solids accumulation at joint transitions.
• ✅ Standards Compliance Conforms to ASTM D2665 and CSA B181.2 for DWV applications.

Technical Specifications

• Nominal Size: 3 inches
• Material: PVC, Schedule 40
• Angle: 22-1/2 degrees
• Ends: Hub x Hub (Slip x Slip)

Installation Guidelines

Install using PVC primer and solvent cement conforming to ASTM F656 and ASTM D2564. Proper surface preparation and full pipe insertion depth are essential to ensure bond integrity. Joint cure times must be observed before subjecting the system to in-service conditions. All installations should follow local and national plumbing codes.

Applications

This elbow is commonly used in horizontal DWV configurations where a 22-1/2° change in direction is needed—such as in sanitary stacks, fixture drains, and lateral waste line realignments. It is suitable for both new construction and system retrofits in residential and commercial installations.

Material Insight

PVC DWV fittings offer excellent resistance to internal corrosion, scaling, and microbial growth, making them suitable for long-term use in gravity flow systems. Their non-metallic composition also reduces weight and eliminates concerns related to galvanic corrosion in mixed material systems.

The 3 inch PVC 22-1/2° elbow is a durable and compliant solution for directional alignment in DWV system layouts. Its dimensional stability and solvent-weld design provide a permanent, leak-resistant joint that meets the requirements of plumbing professionals across code-compliant projects.
