Step 1 - Understand the needs of your project

Our online Inspection Chamber selector can help you decide on the right chamber for your next project, but there are also some simple questions you can ask yourself, such as:

• Is my drainage installation adoptable or non-adoptable?
• What is my proposed depth to invert from cover level?
• How many inlets do I need and at which angles?
• What is the diameter of the outlet?
