Abstract:
1. A flush valve actuator assembly for use with a flush valve comprising: a) a base having a bore extending there through; b) a plunger rod having a central longitudinal axis passing there through, wherein the plunger rod is positioned within and guided by the bore of the base; c) a drive mechanism for moving the plunger rod back and forth within the bore wherein the drive mechanism for moving the plunger rod is a movable handle mounted to the base which when moved displaces the plunger rod within the base bore; d) visual indicia identifying a non-axisymmetric orientation of the bore relative to the central axis passing through the plunger rod, said visual indicia disposed to enable calibration of the volume of water passing through the flush valve for each flush cycle; and e) an outer casing, wherein the casing includes the indicia.
