a housing having an interior space, an inlet for coupling the valve assembly with a fluid source, a first outlet directed to the input end of the main body, and a second outlet directed to the input end of the main body; and
a valve core having a column rotatable within the interior space of the housing and a handle extending from the column, the valve core being at least rotatable to at least one closed position corresponding to a closed condition of the valve assembly, a first open position corresponding to a first open condition of the valve assembly from the inlet to the first outlet, and a second open position corresponding to a second open condition of the valve assembly from the inlet to the second outlet, wherein
the valve core is rotatable at least partially around a rotational axis;
the column comprises:
a distal portion through which source fluid can enter from the inlet when the valve
core is in the first open position and in the second open position;
a first output; and
a second output,
wherein the first output and the second output are offset relative to each other along the rotational axis.
