Lost here for sure Id say get a book. I dont see why are how you had a gate valve on the swamp cooler. No that is not the type valve you would use on a washing machine. they are more like a boiler or sill drain C**k. When you say needle valve. that should be one on the swamp cool water line in. it goes in to the saddle valve set up for water to go into the cooler. you would put it on a water pipe and it would make its own hole in the pipe if you have it on open it all the way .As the float in the cooler will let the water in
