Trade Grade 40mm PVC Waste Y Tee, 45 Degree, Solvent Weld

40mm Waste Y Tee

The Trade Grade Waste Tee is a critical component for managing greywater flow in residential and commercial sanitary plumbing installations. This uPVC fitting allows for a 45-degree branch connection, ensuring efficient drainage without the turbulence associated with standard 90-degree junctions. It is designed for standard 40mm waste pipes commonly found in kitchens, bathrooms, and utility rooms.

Built for the Job

Plumbers and site supervisors prioritize flow efficiency when designing waste systems to prevent long-term maintenance issues. This 45-degree branch facilitates a smoother transition for wastewater, significantly reducing the likelihood of debris buildup and potential blockages within the stack. The solvent weld sockets provide a permanent, chemically bonded seal that withstands standard household chemicals and consistent temperature fluctuations. Whether you are retrofitting a sink or installing a complete bathroom suite, this fitting ensures the structural integrity of the secondary drainage network.

• Connecting kitchen sink waste lines to the primary vertical discharge pipe.

• Branching basin drainage in multi-unit residential or hospitality projects.

• Installing high-volume condensate lines for commercial HVAC drainage systems.

Product Highlights

High-Impact uPVC Build

The material is engineered to resist corrosion from harsh detergents, domestic cleaners, and high-temperature water discharge.

Hydraulic Performance

• Precision-molded smooth internal walls minimize friction for rapid waste clearance.
• The 45-degree sweep angle prevents solids from settling at the junction point.

Technical Specifications

What’s Included

• 1 x 40mm 45-Degree Waste Y Tee Junction

On-Site & Workshop Notes

• Ensure all pipe ends are cut square and fully deburred before attempting to seat them in the junction.

• Clean both the pipe exterior and the internal socket with a dedicated PVC primer to ensure a high-strength chemical bond.

• Apply solvent cement evenly and allow the joint to cure fully according to the adhesive manufacturer’s specifications before running water.

• Verify that the fall of the pipework remains consistent after installing the branch to maintain gravity-fed flow rates.
