Drainage Sales offer what is probably the largest range of complete inspection chambers in the UK. Inspection chambers generally come in two diameters, 300mm and 450mm .The choice is governed by the depth and the number of inlets required. Please click here to watch a short video outlining the various choices available.
Inspection Chamber Structure
The inspection chamber itself is comprised of a base, sectional risers with a seal, and a manhole cover that is specific to the required finish.
Additional risers may be added if required, and the last riser can be cut to size to ensure a perfect match with ground level.
You can read more about what inspection chambers are and how they connect in your underground drainage system or watch an instructional video on the use of inspection chambers.
Using Inspection Chambers at a change of direction
When a drainage pipe changes direction by 30° or more, an inspection chamber should be used. Click here to watch a video on how to set up the chamber for a change of pipe direction.
