I'm not good at identifying pipes but to get a better look have you tried to screenshot so. You can take a longer look and zoom in? To screenshot hit the print screen key on the top right of your keyboard then go into paint and hold ctrl and V to paste. You'll have a picture of your screen and will be able to zoom infor a better look.I would normally make a pic for you but can't right now since I'm on my black berry lol. Hope this helps =D
