Product Information

Full details

The FloPlast 300mm Mini Inspection Chamber Set (D300MH1) is an ideal solution for homeowners and contractors managing domestic drainage systems. It provides a reliable, easy-to-install access point for drain maintenance, featuring a robust 35kN load-rated cover suitable for domestic driveways.

Extended Product Information

FAQs

Can this chamber be used under a driveway?

Yes, the provided cover is 35kN load rated, which is appropriate for domestic driveway use.

How do I adjust the height of the chamber?

You can adjust the height by trimming the included 200mm sectional risers with a fine-toothed saw.

Are the side inlets open by default?

No, the side inlets come blanked. You must push out the integral plugs from the inside of the base to open them.

What is the maximum depth of this unit?

The maximum depth from invert to the top of the cover is 740mm.

What type of pipe is this compatible with?

This set is designed for standard domestic drainage piping systems.

Troubleshooting

Side inlet plug is difficult to remove

Apply pressure consistently from the inside of the base unit; avoid using excessive force that could crack the PVC wall.

The chamber cover is not flush with the finished surface

Remove the riser and use a fine-toothed saw to carefully trim the section further to achieve the correct height.

Unstable chamber base after backfilling

Ensure the base is set on a compacted bed of granular material or concrete, and backfill evenly around the sides to prevent movement.

Pros and Cons

Pros

  • Suitable for residential driveway loading (35kN)
  • Easy to customize depth with trimmable risers
  • Flexible inlet options for various pipe layouts
  • Complete kit reduces the need for purchasing additional components
  • Durable, corrosion-resistant PVC material

Cons

  • Fixed width of 300mm may not suit larger commercial pipe requirements
  • Requires careful excavation depth planning
  • Risers must be cut manually for minor adjustments
  • Not intended for high-traffic or public highway use

Setup, Compatibility & Care

  1. Excavation: Prepare a hole that allows for adequate space around the chamber for backfilling with pea shingle or granular material.
  2. Installation: Place the base on a solid, level foundation. Connect the necessary drainage pipes to the main channel or punch out the desired side inlets.
  3. Height Adjustment: Measure the required distance to the surface and trim the 200mm risers with a fine-toothed saw as necessary before stacking them onto the base.
  4. Sealing: Ensure all connections are secure to prevent soil ingress. Use appropriate lubricant on seals if required by specific pipe manufacturers.
  5. Maintenance: Regularly inspect the chamber for debris buildup. The 35kN cover should be checked periodically to ensure the frame remains stable in the surrounding surface material.
  6. Compatibility: Designed for standard domestic drainage pipes; always verify that your pipe outer diameters match the inlet seals provided.
