Soil Pipe & Fittings
110mm soil and vent pipe and fittings in black, grey and white.
Soil Pipe & Connectors
110mm soil pipe in 3m and 4m single socket lengths and 3m plain ended, with double and single socket connectors, pipe clips and spacer brackets to fix it.
Most lines come in black, grey or white to match your stack.
Soil pipe is supplied with fittings only, so add the fittings you need to your basket.
Soil Pipe Bends
92.5° and 45° bends in single and double socket, a tight 90° bend where space is short, an access bend for the foot of the stack, and an adjustable bend for awkward angles.
The 92.5° bends give a built-in fall on horizontal branches.
Most bends come in black, grey or white.
Branches, Bosses & Access
T and Y branches bring a WC or another 110mm branch into the stack, and a double T branch takes two branches at the same level.
Strap-on bosses and a boss pipe give you waste connections for basins, baths and showers, and a socket plug blanks off a spare socket.
Access pipes and an access T branch let you rod the stack if it ever blocks.
Vents & Air Admittance Valves
Vent cowls and a mushroom cowl finish the top of the stack and keep out birds and debris.
A weathering collar and angled flashing seal round the pipe where it passes through the roof.
Air admittance valves let air into the system and stop foul air escaping, which in many installations removes the need to take a vent through the roof.
Reducers & WC Pan Connectors
Reducers step 110mm soil pipe down to 82mm or 68mm, and the soil/rainwater reducer joins a 68mm downpipe into a soil stack.
Straight and bent pan connectors join the WC to the soil pipe, and a 250mm pan extension adds reach where the pan sits further away.

Choosing the Right Soil Fittings
Single socket fittings have a socket on one end and a plain spigot on the other, so they push straight into the next fitting. Double socket fittings have a socket on both ends, so plain pipe pushes in either side. Pick whichever means fewer cuts and joints on your run.
Use 92.5° bends and branches on horizontal runs: the extra 2.5 degrees gives a built-in fall. Use 45° bends in pairs to offset round a joist or a wall.
Put an access point at the foot of the stack and where branches join, so the system can be rodded if it ever blocks. An access bend or an access T branch does the job without an extra fitting.
A vent cowl finishes a stack that goes through the roof. Where the stack stops inside the building or below the roofline, an air admittance valve lets air in and keeps foul air out. Check with your building control officer which suits your job.

Installation Tips
Cut soil pipe square, remove any burrs, chamfer the end and wipe it clean. Apply a thin coat of silicone jointing lubricant and push the spigot fully into the socket.
Clip the pipe at every joint and at regular spacings along the run. Use spacer brackets where the pipe needs to clear render or cladding.
Fit an access bend or access pipe at the foot of the stack so the system can be rodded. Bring waste pipes in through a strap-on boss or a boss pipe.
Where the stack passes through the roof, seal it with a weathering collar or angled flashing and finish with a vent cowl.
Check with your building control officer for the requirements on your job.
