Valve device for improved drainage characterized in that the body of the valve, which is coupled to the lower part of the drain, has, from the coupling flange, an inverted conical extension that occupies approximately half of the height of this body, initiating internally another area of greater inverted conicity that ends in an internal narrowing flange, in the upper part of which is formed with a crosspiece of three radial nerves that at its point of central incidence is constituted in a concentric vertical cylindrical sleeve to the hollow and threaded internally to receive the fixing stud of the upper filter well that closes over the drain hole, with the interposition of a watertight seal; the valve body forming a small, externally cylindrical and threaded conical settlement at its inner lower extremity, in whose seat a triangular section washer is fitted, opened at a perimeter point by a diagonal cut, which by the action of the nut pressure, with flange, threaded to the lower part of the body presses on the end of the drainage duct which serves as a penetration stop the internal narrowing flange, closing hermetically when the washer is compressed against its seating.
