uPVC Waste Reducer 4 Inch x 2 Inch Solvent Weld Fitting

uPVC Waste Reducer 4″ x 2″

The uPVC Waste Reducer provides a critical transition point between 110mm soil pipes and 50mm waste lines in gravity-fed drainage systems. This fitting ensures a secure, leak-proof connection for domestic and commercial plumbing stacks. It utilizes high-grade unplasticized polyvinyl chloride to maintain structural integrity under standard temperature variations.

Built for the Job

Plumbers and site supervisors specify this adapter for integrating secondary waste branches into main soil stacks. The component is essential when connecting sinks, showers, or washing machine outlets to the primary 4-inch discharge pipe. Its robust wall thickness handles the pressures of standard waste flow without deformation. The smooth internal bore prevents debris accumulation and maintains optimal flow velocity throughout the drainage network.

• Connecting 50mm bathroom waste pipes to 110mm main stacks.

• Adapting kitchen discharge lines for vertical soil pipe entry.

• Reducing vent pipe diameters in multi-story ventilation systems.

Product Highlights

Chemical Resistance

The material resists corrosion from household detergents, caustic cleaners, and acidic waste fluids.

Joint Reliability

• Deep socket depth ensures maximum surface contact for solvent welding.
• Precision-molded stops prevent over-insertion of the smaller waste pipe.
• Tapered entry allows for easier alignment during rapid site installations.

What’s Included

• 1 x 110mm to 50mm uPVC Solvent Weld Reducer

On-Site & Workshop Notes

• Ensure all burrs are removed from the cut pipe ends before applying solvent cement to this fitting.

• Verify that the cement used is specifically rated for uPVC to ensure a permanent chemical bond.

• Store these components away from direct sunlight for extended periods to prevent UV-related brittleness.

• Check local building codes regarding the orientation of the reduction to maintain proper air-flow in vent stacks.
