OK, so let me understand this then. I have a Sherwood Blizzard with an air bleed system that maintains positive pressure to keep it dry.(Probably not the right terms to describe the bubbles that flow from the first stage)I'm thinking that by losing that pressure the little rubber poppit would be pressed in and so seal off the first stage preventing water from coming in?

<DIV>I'm probably going to get an Apeks DS4 later on and I'm not sure how that sealed system is designed.</DIV>
