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

22-1/2° PVC Elbow – Engineered for DWV Flow Redirection

The 22-1/2° PVC elbow is designed to provide a smooth, controlled change in direction within drain, waste, and vent (DWV) systems. Its shallow angle enables gradual flow transitions, minimizing turbulence and improving hydraulic efficiency in horizontal pipe runs.

Manufactured to meet ASTM standards for non-pressure applications, this fitting integrates seamlessly with standard Schedule 40 PVC systems. Its structural integrity and dimensional consistency ensure compatibility with solvent-welded assemblies in both new construction and renovation scenarios.

Performance Attributes

• ✅ Accurate Mold Dimensions Allows for consistent joint makeup and proper pitch control.
• ✅ Rigid PVC Composition Delivers excellent corrosion and chemical resistance in gravity-fed systems.
• ✅ Compliance-Oriented Design Manufactured to conform to ASTM D2665 and D3311 for DWV fittings.
• ✅ Ideal for Offsets Used to gradually redirect flow while maintaining drainage velocity and code-required slopes.
• ✅ Solvent Weld Socket Ends Designed for permanent bonding with PVC piping using approved cements.

Installation Guidance

Use standard DWV assembly practices, including pipe cutting, chamfering, dry fitting, and solvent welding. Apply primer and solvent cement per ASTM F656 and F493 specifications. Maintain proper orientation and slope during installation to ensure flow performance and system compliance.

Application Context

This 22-1/2° elbow is typically used in multi-fixture drainage lines where a gradual redirection is required to maintain flow velocity without introducing excessive head loss. Common placements include under-floor drainage runs, horizontal offsets, and layout adjustments behind framing members.

Material Insight

PVC DWV fittings are preferred in modern plumbing due to their ease of handling, resistance to internal scaling, and long service life in wastewater systems. Their low thermal conductivity and lightweight design simplify installation while reducing structural loading.

When system reliability and code compliance are priorities, this 22-1/2° PVC elbow delivers consistent performance and installation efficiency. It’s a fundamental component for any contractor aiming to build durable, well-graded drainage networks with minimal service callbacks.
