Description
The 315mm manhole chamber riser 169mm high is used to build up the height of a compatible 315mm inspection chamber. It helps bring the cover and frame closer to the finished ground level while keeping the chamber accessible for inspection, rodding and maintenance.
This Pipelife riser is part of the 315mm Universal Access Junction chamber system for 110mm underground drainage layouts. It is suitable for domestic drainage, extensions, garden drainage, repairs, outbuildings and light-duty site drainage work.
The riser has a 315mm diameter and a 169mm height. It is stackable and includes a cutting indicator, making it useful when extra chamber height is needed on site.
315mm Manhole Chamber Riser for Drainage
The 315mm manhole chamber riser is designed for compatible 315mm chamber bases. It allows the chamber height to be increased while keeping access available after the drainage system is installed.

315mm Manhole Chamber Riser 169mm High
This 315mm manhole chamber riser adds height to a compatible chamber assembly. It can be stacked where extra height is required, provided the final chamber depth and site specification allow it.
Before installation, check that the chamber base, riser and cover are all compatible. Also, confirm the finished ground level, cover type and loading requirement before fitting the system.
For best results, make sure the joint area is clean before assembly. Use suitable pipe lubricant on seals where required.
315mm Manhole Chamber Riser Installation Use
The 315mm manhole chamber riser should be installed as part of a properly supported chamber system. Correct bedding, backfill and support help keep the chamber stable after installation.
The chamber should sit level, and the riser should connect securely to the chamber base or another compatible riser. The cover and frame should remain accessible after the drainage work is complete.
Always follow the site specification and manufacturer guidance. The number of risers required will depend on the chamber base, cover type and final invert depth.
