110mm Black Soil Pipe & Fittings – Bends, Reducers, Vents, Branches & Bosses

The 110mm black soil pipe system is an essential part of above-ground drainage, designed to carry wastewater and ventilation from toilets, sinks, and baths to the main drainage system. Made from high-quality PVC-U, it is durable, lightweight, and resistant to corrosion.

• Application: Used in soil, vent, and waste systems

2️⃣ 110mm Black Soil Pipe Fittings

📌 Bends (Elbows) – Changing Pipe Direction

• 87.5° Bend: Standard right-angle turn in a soil system
• 92.5° Bend: Slightly more open angle, often used in stacks
• 45° Bend: Used for smoother directional changes
• 30° / 15° Bends: Ideal for gradual adjustments

📌 Reducers – Connecting Different Pipe Sizes

• 110mm to 50mm Reducer: Adapts large soil pipes to smaller waste pipes
• 110mm to 82mm Reducer: Connects to smaller diameter systems
• Multi-Size Flex Reducers: Flexible rubber adaptors for mixed material pipes

📌 Vent Pipe & Air Admittance Valves (AAVs)

• 110mm Vent Pipe: Allows air circulation, preventing siphoning in waste systems
• Air Admittance Valve (Durgo Valve): Auto-opens to balance pressure & prevent bad smells

📌 Branches – Connecting Multiple Waste Pipes

• 110mm 87.5° Double Branch: Joins two horizontal pipes into a vertical stack
• 110mm 92.5° Branch: Alternative design for vented systems
• 110mm 45° Branch: Provides a smoother connection for waste pipes

📌 Boss Fittings – Connecting Smaller Waste Pipes

• 110mm Boss Pipe: Allows 32mm, 40mm, or 50mm waste pipe connections
• 110mm Boss Adaptor: Converts boss outlets to fit various waste pipes

3️⃣ Installation Notes

✔ Use solvent weld or push-fit fittings depending on your system
✔ Secure pipes with brackets every 1m vertically & 2m horizontally
✔ Vent pipes should terminate above roof level
✔ Use a silicone lubricant for push-fit connections
