The FloPlast 450mm Inspection Chamber Set (450MH1) is an essential solution for homeowners and contractors managing 110mm drainage runs, providing a secure and accessible point for system maintenance. It features a robust 450mm diameter base with multiple inlet options and an 800mm total depth, making it ideal for domestic driveway applications. The primary caveat is that while the risers can be trimmed for shallow installations, achieving depths greater than 800mm requires the purchase of additional sectional risers.

Yes, the included circular cover is rated to 35kN, which is appropriate for domestic driveway traffic.
Yes, this unit is specifically designed for 110mm drainage runs.
The set provides an overall depth of 800mm from the invert to the top of the cover.
Yes, you can purchase additional sectional risers to increase the depth beyond 800mm.
The integral plugs can be removed by applying pressure; a hammer and a blunt tool may be used to carefully tap out the plugs if necessary.
The base has a diameter of 450mm.
Ensure the pipe is inserted fully and check that the rubber seal is correctly seated within the inlet housing.
Purchase additional 235mm sectional risers to achieve the required depth.
Check that the frame is perfectly level and that no debris is trapped in the frame recess.
To install, prepare a level sub-base of granular material. Connect your 110mm drainage pipes to the base unit inlets by pushing out the factory-fitted plugs. If the site depth is less than 800mm, use a fine-toothed saw to carefully trim the riser height before securing it to the base. The chamber is compatible with all standard 110mm PVC-u drainage systems. To maintain, periodically remove the 35kN cover to check for debris or blockages within the base channel, ensuring the system continues to flow freely.
