450mm Diameter Chamber Riser by Brett Martin

The diameter and invert of this drain riser from Brett Martin are 450mm and 325mm, respectively. Wherever a branch pipe connects a major drainage pipe, inspection chambers should be placed. The drain inspection chamber riser is ideal for shallow access chambers. This specific drain riser is attached with a rubber seal that makes the joint waterproof and rests on top of the inspection chamber base.

Although more drain risers may be added to increase the height, this drain riser is best for shallow access inspection chambers.
