Hello,
Today I checked scrubber again, but this time turned it with spring facing up and tapped it and turn, now bottom is ok but if you try to tighten nut more down it cannot due to thread finish so I think I did the mistake not to fill it properly and needed more tapping. Now if I put in on spring it will take the space as there is about 5mm to 10mm loose, so I will have to scrap it what you guys think? Believe it or not this is after my 2nd rebreather dive during the course as everything happened from weather, buddy going abroad Xmas holidays

Hopefully I will finish couse as I do it on Sundays!
