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.

Types of Inspection Chambers

As chambers are used in a variety of different situations in your drainage system, we think it's only right that we should offer you a choice.

Unlike most merchants who offer two types of chamber, Drainage Sales stock nine different chamber options, in addition to various sectional parts.

So whether you require a round or square cover, a deep or shallow invert, internal or external use, you can find what you need in the list below if you can't, just give us a call on 01206 931404 - the chances are we can make one up for you!
