Oh yeah - I know what you mean. I've seen that before as well. Although he seems to know his stuff very well, and is very helpful, and takes the time to help out a lot of people. I'm still trying to figure out the physics behind this gravity check valve situation though. I still can't figure out why it doesn't work at a 45deg angle. And more importantly, I don't understand why a checkvalve with a hole in it works any better than a ball valve 1/4 open....
