Description
Overview
The 400 mm manhole extension is a large underground chamber with a child-safe lid, used ahead of a septic tank. All the underground 110 mm pipes from the building lead into the chamber, and a single pipe then runs on to the septic tank. It gives you one clean junction point to inspect and clear blockages without digging up pipework. The unit is 1060 mm in diameter and 790 mm high, supplied complete with its lid.
It is moulded from high grade linear low-density polyethylene, made to withstand underground pressure and thick enough to keep roots and rodents out. Use it ahead of a septic tank such as the 600 L combo where you have several drain lines to combine. See more in the septic range.

Where it works
A junction chamber suits buildings with multiple drain lines, such as lodges in Limpopo with several chalets, farm compounds in the Free State, schools and clinics in Mpumalanga and larger homes in Gauteng. Have a qualified builder or plumber do the installation, check the ground for groundwater and clay beforehand and keep vehicles off the chamber.

Questions about this product
What is a manhole extension chamber used for?
It sits ahead of the septic tank. All underground 110 mm pipes from the building lead into the chamber, and a single pipe then carries the flow to the tank. It gives you one access point to check for blockages.
What size is the chamber?
The chamber is 1060 mm in diameter and 790 mm high, supplied as one complete unit with a child-safe lid. Allow for the full diameter when you dig the excavation and for working room around it.
Can I install it myself?
The maker recommends a qualified builder or plumber. Check the ground for groundwater and clay before digging, and keep the chamber away from areas where vehicles can drive. Delivery is to the property entry point, so plan how to move it to site.
