1-1/2 inch PVC DWV Vent 90 Degree Elbow Plastic x Plastic

1-1/2 inch PVC 90° Vent Elbow – DWV Fitting for Directional Venting in Drainage Systems

The 1-1/2 inch PVC Vent 90 Ell DWV PXP is designed for use in non-pressurized drain, waste, and vent (DWV) systems where controlled changes in direction are required. This fitting enables a smooth 90-degree transition in horizontal or vertical vent piping layouts, maintaining system airflow and compliance with mechanical code requirements.

Molded from high-strength PVC, the elbow offers excellent dimensional stability and chemical resistance, making it suitable for use in residential and light commercial sanitary systems. Socket end connections allow for solvent-weld joining to schedule 40 DWV piping.

Key Product Features

• ✅ Schedule 40 PVC: Manufactured from rigid polyvinyl chloride suitable for DWV systems per ASTM D2665 or D1785.
• ✅ 1-1/2 inch Nominal Size: Compatible with standard drainage and vent piping in residential construction.
• ✅ 90° Ell Configuration: Facilitates sharp directional changes in vertical or horizontal vent runs without flow obstruction.
• ✅ Socket x Socket Connection: Designed for solvent cement welding to provide a permanent, leak-resistant joint.
• ✅ Corrosion-Resistant: Impervious to rust and common household effluents, extending service life in sanitary systems.

Installation Guidelines

Install using appropriate primer and solvent cement for PVC materials. Ensure full socket insertion and alignment before setting. Fittings must be supported in accordance with code to prevent joint stress or misalignment. Not intended for use in pressurized systems or applications subject to high thermal expansion.

Application Use

This vent elbow is commonly used in DWV systems behind walls, in ceiling spaces, and within vent stacks. It maintains proper atmospheric balance in drain lines, preventing siphoning of traps and promoting efficient waste discharge by allowing air movement.

Technical Note

Proper vent system design is critical to maintaining neutral air pressure in drainage systems. Fittings such as the 90° PVC vent elbow play a vital role in allowing gases to escape and preventing pressure fluctuations that can compromise trap seals.
