I'm familiar with the loss of air bubble problem on Megaflows. Is it ever curable without installing an external PV or is that simply just the way to go for a permanent cure. Client needs convincing, and I don't do or see enough of these things to be authoritative on whats best to cure it of losing its air bubble.
