Standard uPVC 3 Inch Waste Pipe, 6m Length, Grey

uPVC 3 Inch Waste Pipe

The Standard uPVC 3 Inch Waste Pipe, 6m Length, Grey serves as a fundamental component for domestic and commercial sanitary drainage systems. Plumbers and site supervisors utilize this specific diameter for secondary ventilation stacks or primary waste lines in medium-density residential projects. This high-grade unplasticized polyvinyl chloride material ensures long-term resistance to chemical corrosion common in household detergents and waste liquids.

Built for the Job

This plumbing component handles non-pressure applications where gravity-fed drainage is required. The 3-inch (82mm) external diameter provides sufficient capacity for high-flow fixtures while maintaining a compact profile within wall cavities or floor voids. Contractors prefer this material because it remains rigid over long horizontal spans when supported correctly. The smooth internal bore minimizes friction, which significantly reduces the risk of sediment buildup or blockages over the life of the installation. It withstands standard site handling and resists impact damage during the rough-in phase of construction.

• Vertical soil and waste vent stacks in multi-story buildings.

• Horizontal discharge pipes for bathroom groups and kitchen clusters.

• External rainwater downpipes for large roof surface areas.

Product Highlights

High-Impact uPVC Construction

The material blend provides excellent structural integrity and resistance to common site chemicals and acidic soil conditions.

Hydraulic Efficiency

• Mirror-smooth internal surface prevents debris snagging.
• Consistent wall thickness ensures uniform strength across the 6-meter length.

Technical Specifications

What’s Included

• 1 x 6-Meter Length of 3-Inch uPVC Waste Pipe

On-Site & Workshop Notes

• Always chamfer the cut end of the conduit to a 15-degree angle before applying solvent cement to ensure a leak-proof bond.

• Store these lengths on a flat surface in the yard to prevent bowing or warping before installation.

• Support horizontal runs with clips at maximum 1.2-meter intervals to maintain the required fall and prevent sagging.

• Ensure an expansion gap of roughly 10mm is left in push-fit joints if using compatible fittings to account for thermal movement.
