I've just bought (picking up this weekend) a set of PST LP120's with a 200 Bar manifold. As it is late in the season and this is my first double, I do want to use them on my next dive but not as doubles. Also, I dont want to get into a huge boyency issue with two 120s straped on my back. What is the procedure for splitting them up? The valves are DIN with yoke adapters. Do you back out the manifold and screw in a cap. I'm going to go to my regular shop but I'd like to know what should happen before I go. Ill put them back together to play arround with them at my club pool session.
