Choosing an Osma Inspection Chamber

The amount of choice available when it comes to choosing an Inspection Chamber can be daunting, so we’ve put together a simple step-by-step selection guide to help you. You, firstly, need to understand the needs of the project. For example, is my drainage installation adoptable or non-adoptable? What is my proposed depth to invert from the cover level? How many inlets do I need and at which angles? What is the diameter of the outlet? Wavin offers a comprehensive range of inspection chambers ranging in shaft diameters from 200mm up to 600mm, having either single or multiple inlets and outlets ranging from 110mm up to 300mm. Once you have answered the above questions, use the inspection chamber selector to decide which to specify or use.
