Pilot design of an efficient, leak-proof and economical flush system

ABSTRACT

In the last decades, water consumption per capita has been reduced. Nevertheless, several countries look for additional reduction in water consumption through better process of equipment functions. This paper describes a new design for an economical flush system in which there is neither flapper nor gasket that could leak. Prototypes with new design have been made and tested; after a 12 months’ test with one of them, by a family of 4 people, the project had good performance, with reduction in water consumption. This new design does not use gasket, works with two boxes (internal box and external box), presents good drag ability and demonstrates good water efficiency both for 3 L and 6 L flushes.
