Inspection Chamber Base – PVC – Residential & Commercial Use

Product Overview

The 450mm inspection chamber base is designed with multiple fixed inlets for efficient underground drainage systems. It provides dependable access for inspection, maintenance, and rodding of foul and surface water pipework, making it suitable for both domestic and light commercial installations. Made from high-strength, durable materials, this chamber base ensures long-term performance and watertight integrity. Its multiple inlets accommodate various pipe connection layouts, perfect for junctions, changes in direction, or complex drainage configurations.

This component allows several 110mm or 160mm pipes to converge at a single access point, and serves as a transition between different pipe gradients or levels, maintaining flow performance across vertical changes. It can be installed as an intermediate access point between manholes, typically every 45 metres on straight drainage runs, offering a practical and economical system maintenance solution. The design integrates seamlessly with standard 450mm risers and covers, ensuring a secure modular assembly and straightforward installation.
