It happens again recently and yesterday I was fed up so I dismantled the flow control to do a cleaning (and replace the o-rings). I did not replace the o-rings (they are a pain in the ass to remove, and also, still elastic), but found out a loose piece of metal where the spring is. No idea where it came from. Remove it, do some cleaning, and low and behold, everything is good again. No hissing sound, no drop!
I can’t still make the flow control to completely stop. Even at the tightest level it still have some flow. Am I missing something?
