Abstract

Improved drainage system, characterized essentially by the fact that it is constituted by a siphon, which is coupled with a cylindrical tube that is concentrically disposed inside it in considerable magnitude, torn from the body of the siphon the drainage pipe, which is constituted by a short solid section thereof, topped off at the free end by a coupling or thread, intended to connect with the conventional tubular evacuation element, forming the body of the siphon, the concentric cylindrical tube and the drainage tube one piece, being also characteristic is the fact that the projecting upper section of the cylindrical tube housed in the siphon branches into two short tubular extensions terminated by two threaded couplings, in which they fit corresponding elbow tubes which in turn are crowned by threaded couplings that receive the terminal tubes provided with the drainage ports, comprising at least not of said end tubes an overflow, composed of a transverse conduit that, forming a unit with it, is coupled to a corresponding elbow pipe, at the upper end of which is attached a section of straight tube telescopically displaceable and topped by the mouth of the overflow, taking place in each case the coupling that establish both ends, upper and lower, of the elbow tube that involves the overflow, by reciprocal plugging of the spliced tubes, establishing the firmness and the desirable tightness in this joint by means of an O-ring.
