Tuscan EN877 Soil is a socketless cast iron soil, waste and rainwater system made to BS EN 877. Plain-ended pipes and fittings are joined with stainless steel or ductile iron couplings, giving a slim, continuous line on a façade or in a service riser. Cast iron is non-combustible, quiet in use and very long-lived. That is why it remains the specification of choice for heritage buildings, tall stacks, and anywhere acoustic performance or fire safety matters.
Tuscan EN877 Soil Taper Pipe
A taper pipe that joins two different diameters in the same run.
Available in 14 sizes, from 70mm × 50mm to 300mm × 250mm. Nominal weights run from 0.6 kg (70mm × 50mm) to 9.9 kg (300mm × 250mm).
Typical use: Changing pipe size within a stack or drain, or connecting to an existing pipe of a different size.

Frequently asked questions

It is available in 70mm × 50mm (HS3046), 100mm × 50mm (HS4046), 100mm × 70mm (HS4047), 150mm × 50mm (HS6046), 150mm × 70mm (HS6047), 150mm × 100mm (HS6048), 200mm × 100mm (HS8046), 200mm × 150mm (HS8047), 250mm × 100mm (HS10046), 250mm × 150mm (HS10047), 250mm × 200mm (HS10048), 300mm × 150mm (HS12046), 300mm × 200mm (HS12047), 300mm × 250mm (HS12048).
How are taper sizes described?
By the two diameters it joins, larger first. A 100mm × 50mm taper joins a 100mm pipe to a 50mm pipe.
Can I reduce the size of a soil stack going downwards?
A stack should not reduce in the direction of flow. Tapers are normally used to increase size downstream, or to connect smaller vent and waste pipes.
