Inspection chambers provide access to underground drainage systems and are an essential part of underground drains. A manhole cover helps allow easy access to those who need to inspect or clear blockages in drains under the ground. Our inspection chambers are available in a choice of sizes and dimensions and made from high quality materials that are made to last.
It is important that underground drains are inspected regularly and for this, an inspection chamber is required. Inspection chambers provide an access point to underground drainage systems and are made up of a number of elements, including base, risers, seal and cover, which are all vital to a quality working manhole cover.
Where Should An Inspection Chamber Be Installed? Inspection chambers should be present wherever there is a branch pipe joint or where the pipe changes in direction by more than 30 degrees or if the run is longer than 22m. The best way to check if you have installed the inspection chamber in the correct place is to make sure that you can reach a rod to every single part of the drain.
