Product Information

Full details

The FloPlast 300mm Mini Inspection Chamber Set (DMH3005) is an ideal solution for contractors and DIY enthusiasts managing domestic drainage systems. This comprehensive set provides a versatile base and riser system that reaches a standard depth of 725mm, allowing for easy access to inspect or clear blockages in drainage lines. While the unit is durable enough for driveway installations rated at 35kN, it is specifically designed for lighter-duty domestic use rather than heavy commercial traffic areas.

Extended Product Information

FAQs

Can this chamber be used under a path with heavy foot traffic?

Yes, the 35kN load rating is well within the requirements for pedestrian and residential vehicular access areas.

How deep is the system out of the box?

The total depth from the invert to the top of the cover is 725mm.

What tools are needed to cut the risers?

A standard fine-toothed hand saw is sufficient to cut the plastic risers to the desired height.

Is the unit watertight?

When assembled correctly according to the manufacturer's instructions, it is designed to manage drainage flow effectively.

Can I add more risers to increase depth?

The system is designed for the provided configuration; adding extra risers may exceed the structural stability of the assembly.

Does it come with a seal for the base?

The base features internal integration for connectivity, but ensure you follow standard plumbing practices for pipe-to-chamber connections.

Troubleshooting

Difficulty inserting pipe into side inlet

Ensure the internal blanking plug has been fully removed and check the pipe for burrs or sharp edges that might catch on the seal.

Cover does not sit flush with the frame

Check for debris in the frame channel or ensure the frame is installed on a perfectly level surface.

Riser seems loose during assembly

Verify that all O-rings or seals are correctly seated in the groove before tightening the connection.

Pros and Cons

Pros

  • Lightweight construction reduces physical strain during installation
  • Modular risers allow for precise depth adjustments
  • High 35kN load rating makes it safe for driveway use
  • Integrated blanking plugs simplify multi-directional drainage connectivity

Cons

  • Not suitable for heavy commercial traffic or main road applications
  • Requires professional cutting tools for height adjustment
  • Square frame requires accurate ground leveling during installation

Setup, Compatibility & Care

Installation requires a level, compacted bed of pea shingle or sand to support the base. Ensure the side inlets are oriented correctly before finalizing the base placement. For the risers, check for any debris before sealing the joints to ensure a watertight fit. The cover should be bedded into the frame using a suitable mortar or sealant consistent with standard paving practices. Regular maintenance involves simply removing the square cover and clearing any sediment or blockages that may have accumulated in the open base channel.
