Well, let me start by saying that Atomic and Dive Rite regulators have a factory service interval of TWO years, not one. I know that the Dive Rite regulator is identical to another brand regulator (because they make it), but the other regulator's service interval is only one year. What gives? What I believe is business covering their a$$es. I know the regulators are good for two years.
Now as far as a regulator failing and it causing a problem. Well honestly the only problem is the dive will have to be aborted. Do you really think a failed regulator is going to kill either of us?? Come on, we dive as a good buddy team and also dive completely redundant air sources.
I do have a question for you though, about the "monkey" working on my regulator. I only know of one really qualified regulator technician, and he is located in Chicago (far away from Reading, PA). So my question is how do you find a good regulator tech, rather than a "monkey". My second part of that question is how do I become a regulator tech?
You see, I know from my many years as a locksmith that if you want something done right, you have to do it yourself. I am always fixing other "professinals" mistakes. For example last night I was called out after 3:00am because the front door of a new Starbucks store would not lock. I found that the person that installed the locks, for some reason decided that some of the parts were not important enough to install. SO, I had to fix his mistake to make things right.
Bottom line, I would service my regulators 2 times a year if I could do it myself and I would love to go that route.
