Product Information

Full details

The Polypipe WS64W Knuckle Bend is designed for plumbers and DIY enthusiasts needing to create a secure 90-degree directional change in 50mm solvent weld waste systems. Its key benefit is providing a reliable, leak-resistant connection for domestic drainage. A potential caveat is that it specifically requires solvent weld cement for installation, which is not included and requires proper ventilation during use. This white ABS fitting integrates seamlessly into household waste removal from sanitaryware and kitchen appliances, forming a crucial part of a comprehensive waste water management system.

FAQs

What type of adhesive is needed for this knuckle bend?

This knuckle bend requires a solvent weld cement specifically designed for ABS waste pipes. This adhesive is not included with the fitting and must be purchased separately.

Can this fitting be used with push-fit waste systems?

No, this fitting is designed exclusively for solvent weld jointing. It cannot be directly connected to push-fit systems without appropriate adaptors.

What is the maximum temperature this fitting can withstand?

While ABS is robust, continuous exposure to very high temperatures (above 60°C) is not recommended for standard waste applications. For most household waste, it performs reliably.

Does the anti-microbial technology require any special maintenance?

No, the BioCote® anti-microbial technology is integrated into the material during manufacturing and does not require special maintenance. Standard cleaning practices are sufficient.

Is this fitting suitable for outdoor use?

While ABS is UV resistant to some degree, prolonged direct sunlight exposure may accelerate degradation. For external applications, consider specific UV-resistant piping systems if longevity is a major concern.

What is the main advantage of using ABS over PVC for waste systems?

ABS offers a good balance of strength, impact resistance, and ease of joining with solvent cement. It often performs well in a wider range of temperatures compared to some PVC formulations.

Troubleshooting

Joint leaks after installation

Ensure the correct solvent weld cement was used and applied properly. Check that the pipe was fully inserted into the socket and held firmly during the initial setting period. Re-cutting and re-joining may be necessary if the initial joint was compromised.

Difficulty inserting pipe into fitting

Ensure both the pipe end and the fitting socket are clean, dry, and free from debris. Verify that the pipe is the correct diameter for the fitting (50mm). Ensure adequate solvent cement has been applied, as it acts as a lubricant.

Fitting appears to be degrading or softening

This may indicate exposure to incompatible chemicals. Ensure only standard household waste is being discharged. Check that excessive heat is not being applied to the pipework.

Pros and Cons

Pros

Provides a secure and leak-resistant 90-degree turn in waste pipe runs.
Durable ABS construction ensures longevity in residential applications.
Solvent weld jointing creates a permanent and robust connection.
Compatible with a wide range of Polypipe waste system components.
Includes anti-microbial technology for enhanced hygiene.

Cons

Requires specific solvent weld cement for installation (not included).
Installation requires adequate ventilation due to solvent fumes.
Not suitable for push-fit or compression jointing systems.
Color is specifically white, which may not suit all aesthetic requirements.

Setup, Compatibility & Care

Setup:

Ensure pipes and fitting are clean and dry.
Cut pipes to the required length and deburr edges.
Apply Polypipe solvent weld cement evenly to both the pipe end and the inside of the fitting socket.
Immediately insert the pipe into the fitting socket with a slight twisting motion.
Hold the joint firmly for 30 seconds to prevent movement while the cement sets.
Allow adequate time for the joint to cure according to the solvent weld cement manufacturer's instructions before pressurizing the system.

Compatibility:

This 50mm knuckle bend is designed for use with other 50mm Polypipe ABS solvent weld waste system components. It is suitable for domestic drainage applications, including waste from sanitaryware and kitchen appliances. It is not compatible with push-fit or MUPVC solvent weld systems unless specific adaptors are used.

Care:

Clean the exterior of the fitting with a damp cloth as needed. Avoid using abrasive cleaners or solvents on the fitting itself, as this can damage the ABS material and the anti-microbial coating. Ensure the waste system is flushed regularly to prevent build-up within the pipes.
