Underground Drainage Rest Bend – PVC – Outdoor Drainage Systems

Product Overview

The 110mm Underground Drainage Rest Bend is expertly manufactured from high-quality uPVC, ensuring compliance with BS EN 1401-1 standards for foul and surface water systems. Its robust construction guarantees strength, durability, and long-term resistance to corrosion and chemical attacks.

This rest bend is specifically designed for use at the base of soil stacks, providing a smooth transition from vertical to horizontal drainage. It features push-fit sockets on both ends, facilitating secure and watertight connections to plain-ended pipes. With an 87.5° angle, it is ideal for installation at low levels, near foundations or beneath floors, to minimize blockages and reduce flow resistance.

Features & Benefits

• Heavy-duty uPVC construction: Ensures strength and longevity in underground conditions.
• Rest bend design: Guides waste smoothly from vertical stacks into horizontal runs, reducing turbulence and blockages.
• Secure push-fit sockets: Connects two plain-ended pipes without separate couplers.
• Chemical and corrosion resistance: Withstands foul effluent and aggressive ground conditions.
• Watertight seal: Integrated seals prevent leakage under load.
• Ease of installation: Lightweight and quick to fit with no need for specialist tools.
• 87.5° bend: Provides a controlled right-angle change of direction.
• Double socket connection: Joins two plain-ended pipes directly.

Applications

• Soil stack bases: Connects vertical stacks to horizontal drainage at low level.
• Foundation level installations: Suitable for use near building foundations where drainage exits to external pipe runs.
• Below-floor drainage: Provides smooth directional change under suspended floors or slabs.
• Foul water systems: Suitable for carrying soil and wastewater underground.
• Surface water drainage: Also applicable for rainwater or stormwater systems.

Installation Guidance

• Preparation: Cut plain-ended pipes square, chamfer edges, and clean thoroughly.
• Jointing: Insert pipes into sockets until fully seated against integrated seals.
• Seal protection: Avoid damage to rubber rings during assembly.
• Bedding: Place fitting on a granular base to ensure support.
• Backfilling: Surround with compacted granular material before completing backfill.

• Standard: Compliant with BS EN 1401-1.
• Material: uPVC.
