Inspection Chambers
Inspection chambers are used in drainage to provide access for clearing blocks, inspecting (it’s in the name) and testing the pipework system.
In the picture is a small inspection chamber installed for a customer, they had raw sewage coming up from a gully pot. The pipe from the gulley pot there was connected into the main waste pipe. Unfortunately the original chamber had been buried beneath a pond. This was highlighted by a block that the customer could not clear. The stench pipe ran internally through the living room. In addition, the customer wasn’t keen on a hole being made in the wall and the pipe. Furthermore, if we jetted clear from that point, there is potential of backflow going into the living space. They had another toilet they could use on another run for the time being so we agreed to install a chamber. A hole was excavated to about a 1 meter in depth and 1 meter wide the pipe cut. We then installed a chamber and back filled with pea gravel, we also cleared the block. With the chamber installed the customer can clear any blocks on the run of pipe. In addition, the buried chamber was on a run of pipe connected to a neighbours inspection chamber. If that blocks then it can be cleared from a neighbours chamber.
