Product Overview
110mm Underground Drainage Rest Bend manufactured from uPVC, compliant with BS EN 1401-1 for use in foul and surface water systems.
Its uPVC construction provides strength, durability, and long-term resistance to corrosion and chemical attack.
This bend is designed as a rest bend, specifically used at the base of soil stacks to provide a smooth transition from vertical to horizontal drainage.
It features push-fit sockets at both ends, allowing secure and watertight connections to plain-ended pipes.
Supplied as an 87.5° rest bend, it is typically installed at low level, near foundations or beneath floors, to minimise blockages and reduce flow resistance.
Features & Benefits
- Heavy-duty uPVC construction: Provides strength and long service life in buried conditions.
- Rest bend design: Shaped to guide 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, requiring no 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: Used 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 waste water underground.
- Surface water drainage: Can also be used for rainwater or stormwater layouts.
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.
