To ensure compliance with building regulations, a chamber reducing ring is required to be used if the height (or depth) of a 450mm inspection chamber exceeds 1200mm.

The reducing ring brings the clear opening size of the chamber down to 350mm, the size permitted for all 450mm chamber installations over a depth of 1200mm and up to a maximum invert depth of 3000mm.

The reducing ring clips inside the frame of the manhole cover using a clever snap lock design. It is specifically designed for use with the following chamber covers;

  • CLKS452
  • CLKS456
  • CLKS1657 (not CLKS1657KMB)
  • CLKS450SR
  • CLKS450SR/46SL

This reducing ring, manufactured from recycled polypropylene, is lightweight and easy to install.

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.
