Do you use a cloth in the exhale lung?
After diving the Revo for a year, the most irritating thing was getting water in the loop. This could be due to leaky lips from a knock to the mouthpiece, poor switching techniqu, or lung butter on a longer dive. Due to the "trapless"design of the Revo any liquid ends up in the loop, especially when diving flat, resulting in gurgling on exhale and eventually liquid in the mouthpiece.
I tried a second absorbent cloth in the exhale lung, the same as is installed in the inhale lung, but this didn’t position particularly well due to the smaller size of the exhale lung and I was always concerned that it could interfere with the ADV (automatic diluent valve) in the centre of the lung.
After some thinking, I cut the cloth in half, rolled it lengthways (short, fat) and located it on the left-hand-side but vertically behind the oxygen & diluent pipes. As this is directly below the loop connection, it should do its job more effectively.
I've found this works extremely well over a few months. Firstly, it never moves as the pipes seem to hold it in place. Most importantly, I have never suffered from gurgling loop syndrome. Opening the unit, the cloth is definitely doing it’s job — after two dives totalling 3h30 it was disgustingly soaked in slimy lung butter, yuck.
Wonder what anyone else does?
