Installation
Step 1: Planning and Preparation
Before beginning the installation, it is crucial to determine the proper location for the inspection chamber. Identify the drainage system and assess the pipe layout. Inspection chambers are typically installed when there is a straight run of pipes over 22 meters, a change in pipe size, a significant change in direction, or the presence of a branch pipe. Choose a location that provides easy access for maintenance and ensure the ground conditions are suitable for excavation.
Step 2: Excavation
Dig a hole at the chosen location, ensuring it is large enough to accommodate the inspection chamber. The depth of the hole will depend on the size of the chamber and the required depth for maintenance access. Remember that plastic inspection chambers are rarely installed beyond a depth of 2 meters. Ensure the hole has a stable base, such as a bed of brick or concrete, to provide a solid foundation for the chamber.
Step 3: Pipe Preparation
Before installing the inspection chamber, prepare the pipes that will connect to it. Cut and remove any unwanted sections of the existing pipe carefully. Use a sharp hammer blow to puncture and collapse clayware pipes, and make full-depth cuts for plastic pipes. Ensure that you do not damage the pipework beyond the desired cut section. Clean the pipe stubs and ensure they are clear of any debris.
Step 4: Connecting the Pipes
Use appropriate adaptor couplings to connect the new inspection chamber base to the existing pipes. As plastic inspection chambers have pre-cut openings, ensure these align with the pipes for a secure connection. For clayware pipes, you may need adjustable BandSeal couplings due to the difference in Outside Diameter (OD) between clayware and plasticware. For plastic pipes, non-adjustable adaptor couplings can be used with uPVC pipes. Ensure a watertight seal is achieved by tightening the jubilee clips on the couplings.
Step 5: Installing the Inspection Chamber
Lower the plastic inspection chamber into the prepared hole, ensuring it is level and securely connected to the pipes. Follow the manufacturer's guidelines for proper placement and pipe connections, as each brand may have specific instructions. Ensure the chamber is stable and backfill the area around it with soil or other suitable material to hold it in place.
Step 6: Final Checks
Once the inspection chamber is installed, conduct final checks to ensure proper functionality. Inspect the connections for any leaks and ensure the pipes are securely attached. Verify that the manhole cover fits properly and provides adequate protection for the system and civilians.
By following these steps, you can successfully install a plastic inspection chamber, providing easy access for maintenance and ensuring the proper functioning of your drainage system.

Preparing the base
Firstly, it is important to identify the appropriate location for the inspection chamber. Inspection chambers should be installed if the piping has a straight run that exceeds 22 meters, there is a change in pipe size or direction, or if a branch pipe joins the main drainage run. This ensures easy access for maintenance and inspection of the drainage system.
Once the location is determined, the next step is to prepare the space for the chamber. The base of an inspection chamber should be made of a sturdy material such as brick or concrete to ensure stability and prevent deformation. It is important to follow manufacturer guidelines for proper placement and pipe connections. The base should be level and well-compacted to provide a solid foundation for the chamber.
When installing an inspection chamber in an area with heavy-duty traffic, it is recommended to concrete the chamber to protect its integrity from the heavy load. Additionally, a clearance of more than 300mm should be reserved between the pressure ring and the wellbore to avoid direct force on the inspection chamber due to the settlement of the pressure ring.
The pipes connected to the inspection chamber should be securely attached and free from any debris or blockages. It is important to prevent the flow of effluent or stormwater during the installation process to ensure that the connections are watertight and secure. This can be achieved by instructing the property owner not to use water-dependent fixtures or, if necessary, by placing a stopper in the drain at an accessible point upstream.
The choice between concrete and plastic inspection chambers depends on various factors. Plastic chambers offer advantages such as lightweight construction, ease of installation, durability, and environmental sustainability. They are also compatible with plastic covers and grates, making them safer and easier to handle compared to heavy concrete alternatives. However, concrete chambers are traditionally preferred for their robustness and may be more suitable in certain situations.
