4 inch x 3 inch x 3 inch PVC Double Wye – Designed for Efficient Drainage Systems

The 4 inch x 3 inch x 3 inch PVC Double Wye fitting is engineered to facilitate smooth directional transitions in drain, waste, and vent (DWV) systems. Its geometry supports dual branch connections to a main line while maintaining optimal flow characteristics and minimizing flow disruption.

Constructed from high-performance polyvinyl chloride (PVC), this double wye is suitable for non-pressurized sanitary drainage applications. Its smooth interior walls reduce frictional losses and resist accumulation of solids, contributing to long-term system efficiency.

Professional Performance Features

Designed for code-compliant installations, this double wye offers durability and dimensional accuracy where system reliability is critical:

• ✅ Injection-Molded PVC Fabricated from rigid, corrosion-resistant material meeting ASTM D2665 specifications.
• ✅ High Flow Efficiency 45° angle branches promote unobstructed flow, reducing the risk of clog formation at junctions.
• ✅ Solvent Weld Socket Ends Slip-style connections provide secure joints when installed with proper primer and cement.

Technical Specifications

• Material: PVC (Schedule 40, DWV-rated)
• Configuration: Double Wye – 4 inch x 3 inch x 3 inch
• End Type: Slip x Slip x Slip
• Standard Compliance: Meets ASTM D2665 and CSA B181.2 requirements
• Use: Non-pressure DWV systems

Installation Guidelines

Installation requires proper cleaning, priming, and solvent welding per manufacturer and code requirements. Joint curing time must be observed prior to pressure or flow testing. Orientation must ensure correct directional flow for all branches in the system layout.

Typical Applications

Commonly installed in multi-branch drainage configurations, this fitting supports horizontal-to-horizontal connections in sanitary DWV systems. Ideal for use in residential, commercial, and institutional plumbing systems where multiple fixture branches converge into a main waste line.

Material Consideration

PVC is inert to a wide range of household and industrial chemicals, does not degrade in moist environments, and offers a long service life under standard operating conditions. Its low thermal conductivity and resistance to microbial growth make it ideal for sanitary systems.

The 4 inch x 3 inch x 3 inch PVC Double Wye is a high-performance component for gravity drainage systems, offering dependable flow control and installation flexibility. Specify this fitting for projects where system performance and code adherence are non-negotiable.
