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 88° Single Unequal Branch

An 88° single branch with a smaller inlet than the main run, for example 100mm × 50mm. It brings a smaller pipe into the stack or drain without a separate taper.

Available in 4 sizes, from 70mm × 50mm to 150mm × 100mm. Nominal weights run from 1.5 kg (70mm × 50mm) to 5.1 kg (150mm × 100mm).

Typical use: Waste and branch connections into a larger stack or drain.

Frequently asked questions

What sizes is the Tuscan EN877 Soil 88° Single Unequal Branch available in?

It is available in 70mm × 50mm (HS3020), 100mm × 50mm (HS4020), 100mm × 70mm (HS4021), 150mm × 100mm (HS6020).

How are unequal branch sizes described?

The first figure is the main run and the second is the branch. A 100mm × 50mm branch fits a 100mm stack and takes a 50mm branch pipe.

When should I use an 88° branch?

The 88° branch is the standard choice for bringing a horizontal branch pipe into a vertical stack. The branch pipe is laid to a slight fall, so the junction sits just short of a right angle.

What size cast iron hopper head do I need for my project?

What size cast iron hopper head do I need for my project?

The right size depends on the width of your gutter run and the volume of water you need to collect. The Strayton H42A is available in four widths: 305mm (12"), 355mm (14"), 457mm (18"), and 610mm (24"). As a general guide, wider hoppers suit larger roof areas and heavier rainfall zones. If you are unsure, our team can advise based on your gutter profile and catchment area — call 0333 987 4452.

What is BS 460:2002?

What is BS 460:2002?

BS 460:2002 is the British Standard governing cast iron rainwater goods — gutters, pipes, and fittings. It sets the dimensional tolerances, materials, and performance requirements a component must meet, so that joints seal, sections align, and the system performs as a whole rather than as isolated parts. All Tuscan Foundry Products components are manufactured to comply with BS 460:2002, which is worth citing directly in specification documents and listed building consent applications. The same manufacturing standard applies to bespoke and copy-cast work, even where the profile itself isn't from our standard range.

What building types is the Regent Cast Iron Hopper Head No.1 (H1) suited to?

The Regent H1 is well suited to Victorian and Edwardian terraces, listed commercial buildings, civic and institutional properties, and ecclesiastical buildings where a traditional funnel-form hopper is architecturally appropriate. Its multi-faceted tapering body reads as period-accurate on Gothic and classical building types alike, and it is a commonly specified choice for conservation and listed building projects across the UK.

What building types is the School Board Airbrick suited to?

What building types is the School Board Airbrick suited to?

The School Board Airbrick suits Victorian and Edwardian institutional, civic, and residential buildings where the square-grid airbrick pattern was standard — including school buildings, civic halls, estate housing, terrace houses, and warehouses. It is also appropriate on listed buildings and conservation area properties as a like-for-like replacement for worn square-grid cast iron vents.

Is a brass rooflight opener suitable for use on a listed building?
