Product Information

Full details

This Polypipe 160mm Double Socket Coupling is designed for professional and DIY underground drainage installations, offering a durable and reliable solution for connecting pipes. Its key benefit lies in the innovative push-fit system that significantly speeds up installation. A minor consideration is that it's specifically designed for the Polypipe system, requiring compatibility checks with existing setups. This coupling is constructed from high-strength PVCu and features a terracotta finish, ensuring longevity and compliance with industry standards.

Extended Product Information

FAQs

What material is the coupling made from?

The coupling is manufactured from high-strength PVCu (Polyvinyl Chloride Unplasticised).

What is the diameter of this coupling?

This is a 160mm diameter coupling.

Can this coupling be used for above-ground drainage?

While durable, this specific product is designed and tested for underground drainage applications. For above-ground systems, please consult Polypipe's product range for suitable alternatives.

What standards does this coupling comply with?

It complies with industry standards including BS EN 1401 and BS 4660:2000 where applicable.

How do I ensure a secure joint?

Push the pipe firmly into the socket until it meets the internal centre stop. A secure, watertight joint is achieved when the pipe is fully inserted.

Is this coupling suitable for connecting different brands of pipes?

The coupling is designed for optimal compatibility with the Polypipe underground drainage system. While 160mm is a standard size, performance with other brands is not guaranteed and compatibility should be verified.

Troubleshooting

Difficulty pushing pipe into socket

Ensure the pipe end is clean and free of debris. Apply a small amount of silicone lubricant to the pipe spigot. Check for any obstructions within the coupling socket. Ensure the pipe is being inserted squarely.

Leak detected at the joint

The pipe may not have been inserted fully to the centre stop. Disconnect and re-seat the pipe, ensuring it is pushed in completely and squarely. Check the rubber seal within the socket for damage or debris and clean if necessary.

Pipe does not sit straight

Ensure the pipe is being pushed in straight and not at an angle. If the pipe is difficult to maneuver, ensure sufficient space is available for the push-fit action.

Pros and Cons

Pros

  • Fast and easy installation due to push-fit technology
  • Durable PVCu construction for long-term reliability
  • Ensures secure, watertight joints
  • Compatible with the full Polypipe underground drainage range
  • Meets relevant industry safety and quality standards

Cons

  • Primarily designed for Polypipe systems, limiting cross-brand compatibility
  • Requires adequate space for push-fit connection
  • May not be suitable for highly corrosive environments without specific precautions

Setup, Compatibility & Care

Setup:

  1. Ensure the ends of the 160mm pipes to be joined are clean, dry, and free from burrs or damage.
  2. Mark the insertion depth on the pipe ends using a tape measure or the coupling's centre stop as a guide.
  3. Apply a small amount of silicone lubricant to the spigot end of one pipe if resistance is expected.
  4. Push the pipe firmly and squarely into the socket of the coupling until it reaches the centre stop. A slight twisting motion can help.
  5. Repeat for the second pipe.

Compatibility:

This coupling is designed to integrate seamlessly with the Polypipe range of 160mm underground drainage pipes and fittings. While its 160mm diameter is a standard, always verify compatibility with non-Polypipe systems before installation, especially regarding joint tolerances.

Care:

Once installed underground, the coupling requires no routine maintenance. However, periodic inspections of the drainage system, if accessible, can help identify any potential issues. Ensure the surrounding soil is compacted correctly after installation to provide adequate support.
