Hi all:
I'm curious about a problem I experienced over the weekend. I have an ATX200 second stage as my primary regulator and an ATX 50 as my backup. I love these regulators...very easy breathing and rock solid.
However, I had a minor problem with the second stage (ATX200) over the weekend. First dive was fine...but on the second dive, I noticed that the regulator was flowing a little air. It wasn't free flow, as it happened out of water. It was as if the purge lever was slightly depressed. Sure enough, I took off the cover and the purge diaphragm was putting just enough pressure on the purge lever to allow a slight flow of air. You could get it to stop by loosening the cover.
Between the first and second dive, the regulator got knocked off the bench and onto the dock...there didn't appear to be any damage...but that is my question.
What would cause such a problem? The regulator has been fine for the last year...and then I start to have this problem.
We adjusted the crown orifice to lower the height of the purge lever to stop the problem...but I want to understand what caused the problem in the first place.
Also, let me be clear on one thing...I am taking the regulator in for servicing, just to be safe...I only adjusted it to stop the air flow and went to my backup regulator.
One thing I noticed, when adjusting the crown orifice is that the purge lever would initially lower, then raise back up (while turning the orifice in a counter-clockwise direction). The same would happen when turning the orifice in a clockwise direction. In the end, the actual adjustment as very minimal...just enough to get the purge diaphragm to stop pressing on the purge lever.
Any thoughts?
Thanks;
John
