ABSTRACT:
A snow making system wherein snow making devices, such as snow towers or snow guns, are distributed along a ski slope for producing man made snow with the supply of compressed air and water under pressure in subfreezing conditions. Valving for the supply of air and water to each snow making device is housed underground in a control pit enclosure with a removable access lid. The valves are ganged together for simultaneous operation by a single handle which is exposed through and above the lid for manual operation. The air and water connection hoses are also exposed through and above the lid for connection to an associated snow making device. The handle and these connection hoses are removable to present a flush nonhazardous ground surface in the off ski season. The valves are three-way valves which are adapted to drain all water from the associated snow making device when they are in the off condition in order to automatically drain the devices and protect them from freeze-up.
