View Valsir S.p.A. on TEKEN44Tropea S represents an absolute novelty on the international scene, a state-of-the-art and innovative product: the first cistern in the world designed to reduce the noise generated during use. The experience gained by Valsir in the Triplus, Silere and PP3 soundproof waste systems has enabled us to develop a special plastic compound with the aim of making the flush cistern silent. Laboratory tests show that the perceived noise from Tropea S is 5 times lower compared to the most widely-used cisterns on the market. Furthermore, the internal components of the Tropea S have been certified at the prestigious Fraunhofer Institute in Stuttgart as Class I quietness (both at 3 and 5 bar) according to ISO EN 3822. Tropea S is the only in-wall cistern on the market with a float valve and a stop valve certified at the top of the category in terms of reduced noise emissions
