The water pressure really doenst matter considering that usually you would run it from a garden hose, which is fine for pressure to make snow. You have to have an air compressor that puts out at least 40 psi. Then u connect it into one piece such as a >---, one of the two forks is water the other is air and u should something to control them, then on the straight part u put a female thingy so u can attach nozzles to it that spray mist. I got it all figured out, oh and it has to be like 28 degrees fahrenheit for good snow.
