FAQs

What is the primary purpose of this reducer?

The Polypipe WS28B reducer is used to connect a 32mm diameter ABS pipe into a 40mm diameter ABS pipe within a solvent weld waste system.

What type of jointing method does this product use?

This product uses a solvent weld jointing method, which requires the use of solvent cement to create a permanent bond.

Can I use this reducer with push-fit pipes?

No, this reducer is specifically designed for ABS solvent weld systems and is not compatible with push-fit pipes or other materials like uPVC.

What is the cure time for solvent welded joints?

The cure time varies depending on the solvent cement used and ambient conditions, but it is generally recommended to allow at least 24 hours for the joint to reach full strength before pressurizing the system.

Is this reducer suitable for high-pressure applications?

This reducer is designed for standard residential waste water drainage, which is non-pressurized. It is not intended for use in high-pressure water supply lines.

What are the dimensions of the reducer?

The dimensions are 40mm for the larger socket inlet and 32mm for the smaller socket outlet.

Where is this product typically used in a home?

It's commonly used in kitchen and bathroom plumbing to connect smaller diameter appliance waste outlets or overflow pipes into the main 40mm waste pipe system.

Troubleshooting

Joint is leaking after installation.

This usually indicates insufficient solvent cement application, improper alignment, or premature disturbance of the joint. The joint will need to be cut out and re-made, ensuring thorough surface preparation and correct solvent cement application and curing time.

Pipe does not fully seat into the socket.

Check for obstructions or damage inside the socket or on the pipe end. Ensure the pipe is cut square and deburred. Re-clean and re-apply solvent cement.

Difficulty applying solvent cement evenly.

Use the applicator provided with the solvent cement. Apply a continuous, even coat to both surfaces. Ensure the cement is at room temperature for easier application.

Pros and Cons

Pros

  • Provides a secure and permanent leak-free joint.
  • Offers flexibility in adapting pipe sizes (40mm to 32mm).
  • Durable ABS material ensures longevity.
  • Black finish is ideal for hidden pipework.
  • Compatible with a wide range of Polypipe waste system components.

Cons

  • Requires solvent cement for installation, which needs careful handling and ventilation.
  • Limited to ABS solvent weld systems; not compatible with push-fit or other materials.
  • Specific to residential drainage applications.
  • The solvent welding process demands precision and correct application technique.

Setup, Compatibility & Care

Setup:

  1. Ensure both the 40mm and 32mm pipe ends are clean, dry, and free from burrs. Use a pipe cleaner or fine-grit sandpaper if necessary.
  2. Apply Polypipe solvent cement evenly to the outside of the 32mm pipe and the inside of the 40mm socket.
  3. Immediately push the 32mm pipe fully into the 40mm socket with a slight twisting motion.
  4. Hold the joint firmly for 30 seconds to prevent movement while the cement begins to set.
  5. Allow adequate curing time as specified by the solvent cement manufacturer (typically 24 hours for full strength) before putting the system under pressure.

Compatibility:

  • This reducer is specifically designed for ABS solvent weld waste systems.
  • It is compatible with other Polypipe ABS waste system components, including traps and overflow pipes.
  • It is not compatible with push-fit systems, uPVC pipes, or any other material type without appropriate adaptors (sold separately and not included with this product).

Care:

  • Once installed, ABS solvent weld systems require minimal specific care beyond standard plumbing maintenance.
  • Avoid pouring harsh chemicals or abrasive cleaners directly into the waste system, as these can degrade the ABS material over time.
  • Periodically check for leaks at joint points, though solvent welded joints are generally very reliable.
