The most imitated Made in Italy toilet flushing system on the market, the best in terms of materials and performance. The system is made with cast iron body and details in brass, rubber and high quality plastic that make it durable over time. Designed by Giuseppe Campiglia who uses the notions of physics, applying the Venturi effect to the siphon. This is an oversized model, designed and produced ad hoc for higher or non-standard cisterns. (Out of production)..
