Waste to Soil Adapter Cap – 110mm to 32mm / 36mm Glued Pipe Reducer

Waste to Soil Adapter Cap – 110mm to 32mm / 36mm Glued Pipe Reducer

Features

The waste to soil adapter cap provides a reliable, heavy-duty reduction solution designed specifically for connecting smaller basin waste lines into main 110mm soil and vent stacks. Manufactured with a permanent solvent-welded boss reducer setup, this terracotta adapter features a secure rubber rib-ended spigot that pushes firmly into standard 110mm (4″) plain-ended soil pipes. Furthermore, it bridges bathroom plumbing by accommodating 32mm nominal waste pipes (which measure approximately 36mm in external diameter), ensuring a snug and dependable entry point. Because the reducer comes unglued from the cap during delivery, you can easily apply your solvent cement for a permanent, leak-free fused bond on site. As a result, you achieve a professional, tidy, and watertight connection between your waste and drainage systems.

• Permanent Glued Boss Reducer: Engineered with a solvent-weld connection between the boss reducer and cap. Therefore, it delivers a secure, fused joint that prevents slip or leaks over time.
• Standard 110mm to 36mm Sizing: Precision-built to adapt 36mm outer diameter waste pipes (commonly classed as 32mm or 1 1/4″) into a main 110mm / 4″ soil stack. Consequently, it solves complex cross-size bathroom plumbing challenges.
• Ribbed Rubber Spigot Seal: Features ribbed rubber ends designed to grip plain-ended 110mm soil pipe securely. Moreover, it ensures a tight initial hold before final positioning.
• Distinctive Trade Colouring: Styled with a terracotta-coloured cap paired with a black solvent boss reducer. As a result, it matches standard above-ground drainage components.
• Supplied Unglued for Flexibility: Delivered as separate components that fit together. Furthermore, it allows you to apply your own solvent cement in the exact orientation required for your installation.

Details

Connecting a smaller 32mm basin waste pipe into a large 110mm exterior soil stack often requires awkward multi-fitting bodge-jobs that are prone to leaks and poor sealing. Moreover, finding an adapter that bonds permanently without slipping under water pressure can be a challenge.

Fortunately, this waste to soil adapter cap solves the problem with professional efficiency. Because it combines a secure rubber-ribbed 110mm spigot with a permanent glued boss reducer for 36mm waste pipe, it bridges the size gap seamlessly. Consequently, you achieve a clean, secure, and permanent drainage connection.
