The mounted drain comprises a circular anchoring plate fastened concentrically to a hole in the floor. To the lower surface of the anchoring plate an internally threaded base is fastened by the threading in of a flanged externally threaded pipe that hangs from the inner rim of a circular perforation in the anchoring plate, said flange pipe threading into the base beneath said plate. A novel seal is equipped with a horizontal annular flange that is sandwiched between the bottom surface of the flanged externally threaded pipe on top and the internally threaded base beneath said plate. Said seal also is equipped with a vertical perforation with annual features that seal against the penetrating tubular tailpiece circumference to prevent air and water leakage.
