Inspection Chamber Structure

The inspection chamber comprises f a base, sectional risers with a seal, and a manhole cover that is specific to the required finish.

When is a Manhole Inspection Chamber used?

An inspection chamber is generally used when a branch pipe joins the main drainage run (unless it’s a rainwater pipe).

It can also be used in cases when any drainage pipe changes direction horizontally by30° or more or when there is a straight run of more than 22m.

Is there a choice of Manhole Cover?

Yes, we supply different varieties of manhole covers to fit our chambers, including square, round, recessed and airtight. Your job is to decide the right combination and we’ll do the rest.

Any other tips?

Don’t forget to check whether the rubber seals are in place and all unused inlets have blanking plugs.
