Product Information
Full details
The Wavin OsmaSoil D/SW double socket coupler is designed for professionals and DIY enthusiasts involved in sanitary waste removal systems. Its key benefit is providing a secure and reliable joint for 110mm PVC-U soil pipes using a solvent weld method, ensuring long-term integrity. A potential caveat to consider is the requirement for specific solvent cement for proper installation, which is not included with the coupler itself.

FAQs
What is the purpose of a double socket coupler?
A double socket coupler is used to join two pieces of pipe of the same diameter, allowing for extension or repair of a pipe run.
What type of jointing does this coupler use?
This coupler uses a solvent weld jointing method, which requires PVC-U solvent cement to create a permanent chemical bond between the pipe and the fitting.
Is solvent cement included with the coupler?
No, solvent cement is not included with the Wavin OsmaSoil D/SW double socket coupler and must be purchased separately.
What standards does this product meet?
This product is Kitemarked to BS EN 1329-1:2000, ensuring it meets relevant British and European quality and safety standards for soil and waste discharge systems.
Can I use this coupler with push-fit pipes?
No, this coupler is specifically designed for solvent weld jointing and is not compatible with push-fit pipe systems.
What material is the coupler made from?
The coupler is made from PVC-U (Polyvinyl Chloride-Unplasticised), a durable and corrosion-resistant plastic.
How long does the solvent weld joint take to cure?
The initial set time is usually around 30 seconds to a few minutes, but the joint requires a longer period (typically several hours, depending on temperature and humidity) to fully cure and reach its maximum strength. Always refer to the solvent cement manufacturer's specific instructions.
Troubleshooting
Joint leaks after installation.
This typically indicates insufficient or uneven application of solvent cement, or the joint was disturbed before curing. The affected section may need to be cut out and re-jointed correctly.
Difficulty pushing pipe fully into socket.
Ensure the pipe end and socket are clean and free from obstructions. Check that the correct size pipe and fittings are being used. Reapply solvent cement if the initial application has dried.
Solvent cement not bonding properly.
Verify that the correct type of solvent cement for PVC-U is being used and that it has not expired. Ensure surfaces are clean and dry before application, and that the joint is held securely during the initial set time.
Coupler appears to be the wrong size.
Double-check that you are using a 110mm pipe with a 110mm coupler. Ensure no damage or deformation is present on the pipe end or coupler socket.
Pros and Cons
Pros
- Provides a strong and permanent watertight seal.
- Durable PVC-U material ensures longevity and resistance to common waste materials.
- Kitemark certification offers assurance of quality and compliance.
- Designed for easy integration into existing 110mm PVC-U soil pipe systems.
- Solvent weld jointing is a reliable method for waste systems.
Cons
- Requires specific PVC-U solvent cement for installation (not included).
- Solvent welding requires appropriate ventilation and safety precautions.
- Not suitable for push-fit systems; requires different tools and techniques.
- Limited to joining two 110mm pipes; specialized fittings needed for other configurations.
Setup, Compatibility & Care
Setup:
- Ensure both ends of the 110mm PVC-U pipes to be joined are clean, dry, and free from burrs or damage. Use a deburring tool if necessary.
- Dry fit the pipes into the coupler to check the fit and alignment.
- Apply a sufficient, even coat of appropriate PVC-U solvent cement to the outside of the pipe ends and the inside of both sockets of the coupler. Follow the solvent cement manufacturer's instructions carefully.
- Immediately push the pipes firmly into the sockets of the coupler with a quarter-turn twist to ensure even distribution of the cement.
- Hold the joint firmly for approximately 30 seconds to prevent movement while the initial bond sets.
- Allow the joint to cure for the time specified by the solvent cement manufacturer before handling or stressing the pipework.
Compatibility:
- This coupler is designed specifically for use with 110mm PVC-U (Polyvinyl Chloride-Unplasticised) soil pipes.
- It is intended for use with solvent weld jointing systems only.
- Ensure all pipe and fittings are Kitemarked or certified to relevant standards (e.g., BS EN 1329-1).
Care:
- Wavin OsmaSoil products are generally maintenance-free once installed.
- Regularly check accessible parts of the soil system for any signs of damage or leakage. In case of issues, consult a qualified plumber.
- Avoid using harsh chemicals or abrasive cleaners on the exterior of the pipes or fittings, as this may damage the material over time.
