The check valve = that Andair sells for this application has two tiny holes that allow = flow in the outward direction. So they don't completely stop the leak = but they slow it down significantly. They also should help prevent = siphoning if you are having that problem. I would be interested in more detail about the glasair setup if you have = access to more information.
