This range covers the core 110mm black soil pipe and fittings used to move foul waste safely away from toilets, bathrooms and stacks, whether you’re working on a new install, an extension, or altering an existing run.

FAQ’s:
Is this standard 110mm soil pipe compatible with existing systems?
Yes. These fittings are standard 110mm soil pipe components and are designed to connect directly into most existing black soil pipe systems without modification.
When would I use an air admittance valve instead of venting through the roof?
Air admittance valves are typically used where extending a vent through the roof isn’t practical. They allow air into the system to prevent siphonage but don’t release gases externally.
Do I need access fittings on every soil run?
You should always allow access for maintenance. Access bends, access pipes or access branches make future cleaning or inspection far easier and are often required by building control.
