Tuscan Mechanical BS416 Soil is a coupling-jointed cast iron soil and waste system, dimensionally compatible with BS 416 pipework, in 50mm, 70mm, 100mm and 150mm. Plain-ended pipes and fittings are joined with bolted ductile iron couplings, so a stack goes together quickly and fittings can be replaced later without disturbing the run. Conversion couplings connect it to existing socketed LCC pipe, which makes it well suited to repairs and extensions on period buildings as well as new work. Everything is supplied factory coated and can be painted on site.
Not sure which system you need? Our guide to choosing a cast iron soil pipe system compares all five, with a decision guide for listed and period buildings.






























Yes. Conversion couplings are available in 70mm and 100mm to join the mechanical system to traditional socketed LCC pipework, so damaged sections of an older stack can be replaced without rebuilding the whole run.
Yes. It is cast iron throughout, so it matches the material and weight of original soil stacks. The slim coupled joints and factory-coated finish suit internal and external runs, and the pipe can be painted to match surrounding rainwater goods.
