FAQs
What is the primary purpose of this 92.5° bend?
The 92.5° angle allows for precise directional changes in soil and vent pipe runs, ensuring efficient waste and odour flow while accommodating complex routing in residential installations.
Can I use this bend with pipes from other manufacturers?
While it is designed for the Polypipe PolySoil® system, the 110mm diameter and standard connection types (push-fit/solvent weld) may offer compatibility with other systems. However, using components from the same range is recommended for guaranteed performance and integration.
What is the difference between push-fit and solvent weld connections for this bend?
Push-fit uses an integral rubber ring seal for a watertight connection that is quick to install. Solvent weld uses a chemical adhesive to create a permanent, fused bond between the pipe and fitting, often requiring more time for curing.
Is this bend suitable for underground use?
Yes, when installed correctly using appropriate jointing methods (typically solvent weld for underground applications) and integrated into a properly supported system, it is suitable for underground use within residential drainage.
What is the correct way to clean this component?
Once installed, the bend requires no special cleaning. Standard drain cleaning procedures can be followed. If the component itself is dirty before installation, wipe it clean with a damp cloth.
What does 'SB409B' signify?
SB409B is the Polypipe manufacturer part number (MPN) for this specific product, the 110mm Soil 92.5° Bend with Single Socket in black.
Can this bend be used for rainwater pipes?
This bend is specifically designed for soil and vent applications which carry waste water and manage odours. While 110mm is a common size, it is best practice to use components specifically rated and designed for rainwater systems.
Troubleshooting
Leak at joint
Ensure pipe is fully inserted into socket for push-fit. For solvent weld, verify proper surface preparation and adequate cement application. Re-joint if necessary, ensuring full cure time for solvent welds.
Blockage forming
Check for obstructions within the bend or downstream pipework. Ensure system slope is adequate for gravity flow. Periodic flushing may help prevent buildup.
Difficulty connecting pipes
Verify that pipe ends are clean and de-burred. Use a silicone lubricant for push-fit connections. Ensure the correct pipe diameter and type are being used.
Pros and Cons
Pros
Provides precise 92.5° directional change for optimal pipe runs.
Offers installation flexibility with support for both push-fit and solvent weld connections.
Seamlessly integrates with a broad ecosystem of Polypipe soil and vent accessories.
Designed for efficient waste and odour removal in residential settings.
Durable construction for long-term performance.
Cons
Specific to 110mm diameter; not suitable for other pipe sizes.
Requires careful consideration of connection method (push-fit vs. solvent weld) for proper sealing.
Color is black, which may not suit all aesthetic requirements if visible.
Primarily designed for residential soil and vent, may not be suitable for industrial applications.
Setup, Compatibility & Care
Setup:
Preparation: Ensure the ends of the pipes to be joined are clean, dry, and free from burrs. For solvent weld, lightly abrade the pipe end and fitting socket if recommended by the solvent cement manufacturer.
Connection:
Push-Fit (Ring Seal): Apply a thin layer of silicone lubricant to the pipe spigot. Insert the pipe fully into the socket until it meets the integral ring seal.
Solvent Weld: Apply a suitable solvent cement evenly to both the pipe spigot and the fitting socket. Immediately insert the pipe into the socket with a quarter-turn twist to distribute the cement. Hold firmly for 30 seconds to prevent joint push-out.
Curing: Allow adequate curing time for solvent weld joints before testing or stressing the system, as per the cement manufacturer's instructions (typically 24 hours for full strength).
Compatibility:
This 110mm bend is compatible with other Polypipe PolySoil® system components of the same diameter.
It supports both push-fit ring seal and solvent weld jointing methods. Ensure compatible push-fit pipes or solvent weld pipes and appropriate fittings/adhesives are used.
Integrates with Polypipe ancillaries such as air admittance valves, fire collars, and pan connectors.
Care:
Under normal operating conditions, the installed bend requires no specific maintenance beyond standard drain system checks.
Avoid flushing the system with aggressive chemicals that could degrade seals or pipe material.
Ensure no external impact or excessive load is applied to the pipework.
