Hi folks My Sitech shoulder dump decided to disintegrate before my dive today, so needs to be replaced. I’d like to swap it for an Apeks one, however I believe I need to enlarge the aperture through the suit to enable it to fit. Is it as simple as taking a very sharp knife to it? Is it a straight forward process to replace the dump valves? 15 min job? I need the suit fully-functional for a holiday next week, so if going to an Apeks valve is a major faff I’ll stick with Sitech for the time being, but either way I need to get the fucker sorted PDQ. Cheers! Edit: mods feel free to move thread to ‘drysuits’.
