Abstract: A greywater control valve includes: a housing having an input port and at least two output ports; and an insert including a port connection element and a vent. A rotary greywater control valve includes: a housing including: an input port; a first output port; and a second output port; and an insert that rotates within the housing, the insert including: a connection channel that couples the input port to one of the first output port and the second output port; and a vent channel that couples the connection channel to one of the output ports. A fluid control valve includes: an input port located along a first axis; a first output port located along a second axis that is perpendicular to the first axis; a second output port located along the second axis; and a fluid channel that selectively couples the input port to one of the output ports.
