Manholes and Inspection Chambers
A correctly installed inspection chamber will be essential for clearing blockages, reducing the possibility of costly repair work in future. As a vital access point for maintaining underground drainage, every part of the drainage system should be accessible from the inspection chamber or rodding eye.

Inspection Chamber Sizes
300mm diameter inspection chambers can be effective up to a depth of 600mm. These mini access chambers are usually located close to house and therefore near the top of the drain.
450mm diameter inspection chambers are the standard for rodding and cleaning domestic underground drainage. You can use these chambers at any depth up to 3m, although remember to add a chamber reducing ring to your basket for anything greater than 1.2m in depth.
