The FloPlast Inspection Chamber Riser (D916PK2) is designed for drainage professionals and contractors looking to customize the depth of inspection chamber installations. Providing a durable, 450mm diameter extension for FloPlast D910, D900, and 6D900 bases, these risers ensure a reliable, watertight seal for underground drainage systems; however, users should note that exceeding a total depth of 1200mm requires additional components to meet building regulation standards.

These risers are compatible with FloPlast D910, D900, and 6D900 chamber bases.
Yes, each 235mm riser can be cut to size using a standard fine-toothed saw.
Yes, each riser features an integral rubber seal designed to provide a secure and flexible joint.
You can build up to 1200mm in total height. Beyond this, a CLKS499 chamber reducing ring is required.
The pack contains 2 individual riser units.
No, only a standard fine-toothed saw is required for trimming the height if necessary.
Ensure the groove is free of dirt or plastic burrs from the cutting process; use a silicone lubricant if necessary.
You must incorporate a CLKS499 chamber reducing ring to maintain compliance with building regulations.
Verify that the integral rubber seal is seated correctly in the bottom groove and that the riser is pushed down evenly without tilting.
To install, clear the base of the inspection chamber of any debris. Place the integral rubber seal into the bottom groove of the riser. Align the riser with the chamber base and press firmly to seat the seal. If you are stacking multiple risers, repeat the process for each joint.
Important: If the final stack height exceeds 1200mm, you must integrate a CLKS499 chamber reducing ring to comply with building regulations. For maintenance, periodically inspect the chamber access points to ensure the joints remain secure and that no soil or silt has compromised the integrity of the seals.
