Hmm, re-reading my question, I missed a little detail. It should read, "do you first notice your guage readings drop, or do you first notice the bubble rate slow ?" Sorry about that.
My cylinder is a 20lb. Filled it about 13 months ago. The bubble rate slows at night (only at night). So every morning I open my needle valve a wee tiny bit to compensate. Then it's fine all day, check it again at night, still fine, but by morning it will have slowed again so I open the needle valve a little tiny bit more, and so on. It can slow as much as half, which to me seems a significant rate change.
Going on like this for almost two weeks now.
But the inlet pressure hasn't budged. Still reads 800psi, same as it's ever been since it was filled. Maybe the guage is stuck.
My needle valve is incredibly fussy. Like, if you so much as touch the valve, it will change the bubble rate even though the valve position does not change. Is this normal, are they all like this? Or is this goofy. I run my outlet pressure at about 20psi.
