I really bet that you can do it if you tryed. Half of the fun is messing up and getting sprayed with water while you are testing it. (o wait, thats just me) List out what you have, and I am sure will will be glad to tell you or give you a idea on how to run the hose and stuff like that. But . . . take my advice and have fun putting it together yourself. Then you can tell people "I did this"
*hope I didn't sound like a flamer, didn't mean it to be*
