The present invention discloses a hydrant for selectively supplying water and air under pressure to a snow making apparatus having multiple water nozzles with corresponding water supply conduits and at least one air nozzle with a corresponding air supply conduit. The water hydrant includes a hydrant housing having a water inlet and an air inlet for respectively supplying water and air under pressure to respective water and air chambers within the housing from respective water and air sources. A valve operating shaft is mounted for axial rotation in the housing and spaced water and air valve seats are respectively mounted in the water and air chambers. Water and air valve actuators are secured to this shaft for axial rotation therewith and these actuators respectively rotatably engage the water and air valve seats for selectively valving multiple water ports in the water valve seat on and off while simultaneously valving at least one air port in the air valve seat on and off for selective supply of water and air under pressure to respective of the supply conduits feeding the snow making apparatus.
