Product Information

Full details

The FloPlast Ring Seal Soil Stack Complete Kit is designed for plumbing professionals and experienced DIY enthusiasts tasked with installing or replacing domestic and light-commercial drainage systems. This kit provides all the core components needed for a standard 110mm soil stack installation, offering a high-quality, durable solution that integrates seamlessly with existing British and European standard systems. However, users should note that the kit requires specific site preparation, such as chamfering and lubrication of pipe ends, to ensure a secure, leak-free ring seal connection.

FAQs

Can this kit be used with other brands of pipe?

Yes, as the components are manufactured to standard British and European dimensions, they are compatible with most other soil systems.

Do I need solvent weld for all joints?

No, the primary connections use the ring seal system. Solvent weld is provided for specific instances where a permanent, non-moving bond is required.

Is the anthracite grey color suitable for direct sunlight?

Yes, FloPlast soil components are UV-stabilized for external use, though some fading may occur over many years of exposure.

How do I terminate the pipe if it goes through the roof?

You should use a weathering slate, such as the SP320, to ensure a watertight seal where the pipe passes through the roof tiles.

What is the primary function of the vent terminal?

It allows air into the system to prevent the vacuum effect (siphoning) that can occur during high-volume discharge, which protects the trap seals in your fixtures.

Troubleshooting

Joint is difficult to insert

Check that the pipe end is properly chamfered and that sufficient silicon lubricant has been applied to the seal.

Water leaking at the joint

Disassemble the joint to ensure the rubber seal is seated correctly in its groove and is not twisted or damaged.

Stack is vibrating or noisy

Ensure that the pipe clips are securely fastened and that the pipe is not in direct contact with masonry, which can transmit vibration.

Pros and Cons

Pros

  • High compatibility with existing UK standard pipework
  • Complete kit reduces the need for sourcing individual parts
  • Durable design suitable for long-term external use
  • Easy-to-use ring seal mechanism ensures quick installation

Cons

  • Requires professional-level preparation of pipe ends
  • Not intended for industrial or high-pressure chemical drainage
  • Requires additional specialized parts for roof penetration or internal venting

Setup, Compatibility & Care

For a successful installation, follow these foundational steps:

  1. Preparation: Use a file or deburring tool to chamfer all pipe ends. This is critical to ensure the pipe does not cut the rubber gasket inside the fitting.
  2. Clean: Ensure all surfaces are free of debris or grit before assembly.
  3. Lubrication: Apply a silicon-based lubricant to the pipe end to facilitate a smooth push-fit connection into the socket.
  4. Expansion Gap: Always pull the pipe back by approximately 10mm after insertion to allow for thermal expansion.
  5. Roof Termination: If the stack terminates in a roof space, install an `AV110` Air Valve. For external roof penetration, use an `SP320` Weathering Slate to prevent water ingress.
  6. Maintenance: Periodically inspect pipe clips for tightness and ensure the vent terminal is clear of debris or bird nests.
