ABSTRACT:
An alternator valve assembly particularly suited for use in septic systems for diverting flow from a single inlet to either of two separate outlets. The valve is comprised of a relatively thin walled, blow molded plastic housing which defines a valve chamber having an inlet and a pair of outlets. Valve plug seat areas are located in the housing adjacent the outlets and the outlets themselves each include a hollow sleeve-like collar extending outwardly of the valve housing and tapering slightly inwardly from adjacent the housing. A rubber valve plug is adapted to be received in the valve chamber and placed in one of the outlets to selectively block flow therethrough. The plug includes a sealing lip which is cooperable with the valve seat of the associated outlet and further includes an elongated handle protruding outwardly of the valve housing to facilitate selective movement of the plug between blocking positions with each of the outlets. An outlet box comprised of a relatively thin walled blow molded plastic defining a hollow outlet box chamber is disposed in operative communication with each of the valve housing outlets. Each outlet box, in turn, includes an exit area to permit flow therethrough.
