Flush trap designed by Catis with Venturi effect to fit the toilet water cistern. Utmost care in the choice of suppliers, carefully selected materials, Italian production, every element of the Catis flushing system is of high quality and guarantees products that are both durable and replaceable with equal parts.

The Catis siphon is a battery that includes gaskets and blocking kit, purposefully made for toilet flush box installation. This particular flush siphon is a complete push-button control system using the Venturi effect, made with a cast iron body and high quality brass, rubber and plastic parts. Some modern toilets can be suction operated, thanks to a special siphon placed inside them that creates a Venturi effect, a suction that makes the water flow faster by increasing the cleaning power.
