摘要

A device to avoid the drawbacks of the drains of the sinks, sinks and washbasins, consisting of inserting in replacement of the hydraulic closures commonly used, a small tank (2), from which the dirty water comes out by the action of a siphon formed with the end of the tube (3) that has to lead them to the collection pipe, and by its absorbent action drags all the solid and viscous materials from the water left in the tank, thus making it impossible to clog them.
