This one-piece chamber base and riser forms a 250mm diameter mini inspection chamber with a level invert base. It is usually used in conjuction with our UCL2 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 (when using the UCL2 cover) is 612mm. If you need to make 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.

Inspection Chamber Components

Whilst most customers generally order inspection chambers as sets (base, risers and cover) there are often occasions when it is easier to order the chamber in its individual components. This allows for greater flexibility on site, for example where the final drainage layout is likely to differ from that suggested in the plans, or where the finished ground levels are subject to change.

All of these components can be interchanged with the relevant chamber sets, so if you are simply looking for an additional riser then you are in the right place! Just make sure that the manufacturers of each are the same, as chamber bases and risers from different manufacturers are rarely interchangeable.

All of our inspection chamber components are sourced from reputable supplier partners who are leaders in the UK market such as ClarkDrain and FloPlast.

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.
