Chamber Tees

Chamber tees are a form of curved sewer that is less than the minimum radius requirements for horizontal bends. Because the radius of curvature is less than that required in PS Appendix 5A Clause 5.8.4, they are designed with a size on size inspection opening to allow non-man access for cleaning or inspection.

These are used where site space prevents the installation of a concrete manhole chamber, but a change in direction is required, therefore include inspection / access capability.

Fabricated from a fitting tee body with segmented angles to provide the change in direction.
