What is a soil pipe?

Generally, most homes have a 4-inch (110mm) soil system – but occasionally 6-inch (160mm) pipes will be used. 160mm soil stacks with a soil vent pipe are more common in industrial and commercial installations – and the pipes will be used to transport sewage and waste from toilets, baths, sinks, and appliances into the underground drainage system.

As well as pipework that carries the waste to the sewer, there is also a need for a soil vent pipe – installed to carry potentially unpleasant odours away from the home, to vent above roof level. According to building regulations A soil vent pipe should terminate at least 900mm above the height of any window within 3m. Vent pipes are commonly run outside the building – although soil vent pipes can also be run internally with an air admittance valve added to the vent pipe.

Connecting a waste pipe to a soil stack

To connect a waste pipe (usually either 32mm, 40mm, or 50mm) to your soil stack or soil vent pipe, you’ll need to use a boss. Sometimes, bosses are included on soil branches – but if you need to enter the system somewhere other than a branch or soil manifold, you’ll need to attach a strap on boss.

Fixing a boss into place is relatively simple. You’ll need a hole drill to create the appropriate size hole (to fit the internal lugs of the boss – not the pipe diameter) – and when your hole is tidied, you should apply solvent weld and fit the boss according to its specific instructions. When complete, you’ll have a permanent, watertight boss that’ll bring a waste pipe into the soil stack.

Connecting a plastic pipe to a cast iron soil stack

Of course, it’s not always as simple as connecting into existing plastic pipes – so if you’ve got cast iron or clay drainage, you’ll need to use an adaptor to connect a soil pipe. Generally, an adaptor will fit inside a cast iron pipe – bringing the size of the ground pipe down to the size of the soil pipe or junction you’re connecting in.
