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.
