The FloPlast 300mm Inspection Chamber Base (D820) is designed for professional drainage installers and DIY enthusiasts looking to simplify complex pipe alignments in underground systems. Its primary benefit is the built-in flexibility offered by three adjustable inlets, which can reduce the need for extra bends or connectors, though users should note it is specifically engineered for 300mm diameter systems and requires precise installation for a watertight seal.

Yes, it is fully compliant with BS 7158 standards for inspection chambers.
While it is designed for the FloPlast system, it is intended to connect to standard 300mm drainage pipes, though compatibility should always be verified against the pipe's outer diameter.
Each inlet and the main outlet can rotate 10 degrees in any direction.
This unit is compatible with the FloPlast D820 and D822 side risers.
This chamber base is designed for standard residential or light commercial drainage. Always refer to site-specific loading requirements if traffic is expected.
Using a proper drainage lubricant on the pipe end can make insertion easier and protect the rubber seal during assembly.
Check for debris in the ring-seal and ensure the pipe end is chamfered to allow for smoother insertion.
Verify that the ring-seal is correctly seated and that the pipe has been fully inserted past the seal.
Ensure the area around the base is clear of dirt; minor resistance is normal, but do not force the component if it feels stuck due to soil compaction.
For optimal performance, ensure the base is placed on a stable, compacted foundation of pea shingle or similar bedding material. When connecting pipes, ensure the rubber ring seals are clean and free of debris to maintain a watertight connection. The D820 is specifically designed for use with FloPlast D820 and D822 side risers; do not attempt to force connections with incompatible riser types. Regular maintenance involves periodic inspection of the chamber to clear any debris that might impede flow, following standard drainage maintenance procedures.
