Inspection Chamber Complete Set Level Invert - 250mm Diameter
|Brand||Marley Plumbing & Drainage|
|Material||PVC/ Polypropylene Cover|
|Chamber Type||Level Invert|
|Dimension||Height to Top of Cover 612mm|
This chamber set includes all of the components required to form a 250mm diameter mini inspection chamber with a level invert base. The contents are a one piece base and riser section a circular PVC cover and frame.
Level invert chambers are often used when the installer has little fall to play with on the pipe run, such as when connecting a new section of drainage to an existing pipe run. A standard mini access chamber has an integral fall from the side inlet to the base, and this can take up valuable height when trying to minimise the fall on the new pipe.
The overall depth of the chamber from the invert level to the top of the manhole cover is 612mm. If you need to make small adjustments to the height then the side riser may easily be cut to size using a standard fine-toothed saw.
The main channel of the base is left open and the side inlets are blanked off with integral blanking plugs - simply remove the blanking plug by pushing it out from within the base to open and use the side inlets.
The cover has a 15Kn load rating making it suitable for use in pedestrian areas.

Inspection Chamber Sets
Our chamber sets represent the most popular configurations of bases, risers and manhole covers based on our experience of selling these products over a great many years. We only source these chamber components from market leading suppliers in this field such as ClarkDrain, FloPlast and Marley.
Inspection chamber sets are ideal for those customers who have a good idea of the finished height of the chamber required and the type of manhole cover that will be needed. Final alterations can still be made on site by trimming the risers if required.
On new build sites and extensions, inspection chamber details are usually shown on the plans, making the purchasing of chambers sets a relatively straightforward proposition. As we also sell all of the components individually is it still easy to make amendments (for example adding additional risers) should the chamber specification need to be changed during the build process.
Inspection chambers are a vital part of the underground drainage system, whether it be residential or commercial. They are necessary to provide access into various key points of the underground drainage system. Such access points are used for maintenance tasks such as inspecting and testing pipes to ensure that effluent is flowing correctly and to clear any potential blockages with drain rods or high pressure jetting as required.
