I have a Canon housing for my PS 100 that I have used successfully for many dives. On our last dive trip, one day suddenly I couldn't close the housing any more. The o-ring suddenly was too large to fit. Comparing it now with the unused spare o-ring that the housing came with, the old o-ring is not only larger in length, but thicker in diameter and also feels more floppy than the unused o-ring. Is this normal? I know that o-rings wear out over time, but I never expected it to happen in this way. It's almost as if the o-ring absorbed something and grew larger.
