    Essential Components for Underground Drainage

    Build & Plumb offers a comprehensive range of inspection and access chamber components in popular 315mm and 450mm sizes. All components are compatible with standard 110mm drainage pipes, ensuring straightforward integration and installation.

    What is an Inspection Chamber?

    Inspection chambers provide crucial access to underground pipework for maintenance, blockage removal, and the use of inspection cameras or drain rods. They are ideal for domestic and light commercial drainage systems, unlike manholes, which allow personnel entry. Typically, an inspection chamber comprises three main components:  

    • A base with multiple inlets for pipe connections.
    • Risers to adjust the chamber's height.
    • A cover to secure it at ground level and protect against tampering or debris.

    When and Where to Use Inspection Chambers

    To allow for easy maintenance and inspection, and to prevent blockages and costly repairs, inspection chambers should be installed in the following locations:

    • Wherever a branch pipe joins a main drainage run.
    • Where a drain changes direction by more than 30 degrees.
    • Where a straight pipe run exceeds 20 metres.
