ABSTRACT:
An overflow arrangement which includes an upstanding fluid retaining wall spaced radially outwardly from and encircling an upstanding externally threaded fillneck on a surge tank or overflow reservoir so as to define an annular channel therebetween. A cap adapted to be screwed onto and off of the upstanding threaded fillneck is provided, the cap having a generally circular-shaped top wall, a skirt depending downwardly from a radially outer periphery of the top wall and a radially outwardly extending flange contiguous with a lower extremity of the skirt to a radial extremity overlying an upwardly facing extremity of the upstanding fluid retaining wall. An elastically compressible seal is oriented between the upwardly facing extremity which becomes compressed between the upwardly facing extremity and the radially outwardly extending flange in response to a screwing of the cap onto the upstanding threaded fillneck, the radially outwardly extending flange moving toward the upwardly facing extremity in response to a screwing of the cap onto the threaded fillneck and away from the upwardly facing extremity in response to an unscrewing of the cap from the threaded fillneck. A drain connection is provided leading to a location remote from the tank or reservoir for facilitating a removal of fluid connected in the annular channel therefrom.
