Sounds good to me and I was going to ask if it was so you didn't have to bend over but I thought that would sound rude but that would be why I would do itI ran mine up like mike did for two reasons
1 looks cool
2 I'm to lazy to bend over and see how open/closed the valves are
I'm no expert but that's my 2 cents. There may be a real reason guys are doing it that way
