Extended Product Information
FAQs
What is the purpose of an offset bend?
An offset bend is used in pipework to change the direction of the run, typically to navigate around obstructions like beams, walls, or other services, allowing for a continuous flow path.
What angle does this bend create?
This specific offset bend creates a 135° angle in the pipe run.
What type of connection does this fitting use?
It features a solvent socket on one end and a spigot on the other, designed for solvent weld connections.
Do I need special tools to install this bend?
You will need solvent cement suitable for PVC/ABS pipes, an applicator (like a dauber or brush), and potentially a pipe cutter and deburring tool for preparing the pipes. A tape measure is also essential for accurate installation.
Is solvent cement included with the bend?
No, solvent cement is typically sold separately. You will need to purchase the appropriate type and quantity for your installation.
Can this fitting be used for rainwater pipes?
While primarily designed for soil and vent systems, 110mm pipes are also common in some rainwater systems. However, always confirm compatibility with your specific rainwater system requirements.
What are the dimensions of this product?
The approximate dimensions are Height: 115.0 cm, Width: 150.0 cm, Depth: 200.0 cm, and it weighs 0.3 kg. Note: These dimensions seem unusually large for a single fitting; please verify with product packaging or manufacturer specifications if precise measurements are critical.
Troubleshooting
Joint leakage after installation
Ensure solvent cement was applied correctly and allowed to cure fully. Check for cracks in the fitting or pipe. If leakage persists, the joint may need to be cut out and remade.
Difficulty fitting spigot into socket
Verify that both the pipe and fitting are the correct 110mm diameter and that the ends are clean and free from obstruction or deformation. Ensure solvent cement is not partially cured, which can act as an adhesive prematurely.
Pipework does not align correctly after using the bend
Double-check measurements and ensure the bend is installed in the correct orientation. The 135° angle is fixed; if a different angle is required, alternative fittings may be necessary.
Pros and Cons
Pros
Provides a specific 135° angle for complex pipe routing.
Durable material ensures long-term performance.
Integrates easily with other Polypipe Soil Systems components.
Suitable for both professional and DIY installations.
Helps maintain efficient waste and ventilation flow.
Cons
Requires specific solvent cement for a secure, permanent joint (not included).
Not suitable for above-ground exposed applications where UV resistance is critical without protection.
Precision in measurement and application is needed for optimal performance.
Setup, Compatibility & Care
Setup:
Ensure the pipe ends to be joined are clean, dry, and free from damage.
If using the solvent weld connection, dry-fit the spigot into the socket to confirm the correct depth and alignment.
Apply a suitable solvent cement evenly to the outside of the spigot and the inside of the socket.
Immediately insert the spigot fully into the socket with a quarter-turn twist to distribute the cement.
Hold the joint firmly for the manufacturer-recommended time (typically 30 seconds) to prevent movement.
Allow the joint to cure for the specified time before disturbing the pipework. Refer to the solvent cement manufacturer's instructions for cure times.
Compatibility:
This 110mm bend is designed to connect with other 110mm pipes and fittings within the Polypipe Soil Systems range, as well as other compatible systems using standard 110mm solvent weld or push-fit (if applicable to the connecting component's socket) connections.
Ensure the spigot diameter matches the socket's internal diameter for a proper fit.
Care:
The polypropylene material is inherently durable and requires minimal care during installation.
Avoid using abrasive cleaners or solvents on the exterior of the pipe, as this could damage the surface.
During installation, protect the component from excessive impact or damage.
