ABSTRACT:
This diverter valve (12) is used in conjunction with a faucet (14) and provides for partial diversion of the water supply to a chemical block feeder (20). The diverter valve includes a body 24 having an inlet (26) an outlet 28 and a connecting intermediate passage (32). A transverse diverter passage (42) on one side of the body 24 communicates with the intermediate passage (32) and the diverter passage is closed by an aligned plunger (50) mounted to the opposite side of the body (24). The plunger (50) is withdrawn from its closure position by pulling outwardly and is maintained in the open position by water pressure to partially divert water into the diverter passage (42) to supply diluted chemical into a sink (16).
