<p>The improved sanitary flushing system is comprised of a radially expansible joint (5) made of rubber or elastomer, held by a conical nut (6), and providing both for the tightness between the reservoir (4) and the system, and for the securing of the latter by wedging, both being achieved in a single operation, without using any tool. The system is intended to be retrofitted in reservoirs of flushing systems, regardless of their types, which are integrated to the W.C. bowl or which are independent.</p> |
