Hello Bob...when you say the seconds are simple, what about adjusting them?? I mean, isn't there an adjustment that has to do with pressure {or vacuum} required to make it open??? I guess if you have the gauge it's easy?? Or is it more like as long as it's not leaking air and it opens when you try to breathe it's considered good to go?? Thanks for any info. I bought a used bc with a reg on the inflator. It was only used on one dive. When I tried it out the reg leaked air. I turned the adjustment until it just stopped leaking and it seems to work okay, but doesn't it still really need to be put on a gauge to be sure it's dead on or no????
Go back a few posts. Follow
@Bob DBF 's advice. Go thru
@couv 's checklist, in your case step #10. You'll have your answer.
Yes, I have a magnehelic, and I fine tune my second stages to just where I want them. But telling whether you're in spec or not is as simple as filling the sink.
Whether or not you're trained to adjust a regulator, all divers can check their equipment health with couv's checklist, and probably better than what some shops do for their $200.
As for "adjusting" your spare air until it just stopped leaking, you may have done well, or you may not. There is a fine art to this, which is at least one reason why service is not cheap, and one reason why we crab so much about the quality of the service we get from our LDS. There is indeed a limit to the effectiveness of DIY, unless you put in the effort to learn the theory. Think "Regulator Savvy" for $80 from ScubaTools.
You can do this! But it does take effort.
As for neglected BCD's and their power inflators? There is a reason that that is the most failure-prone piece of gear we dive - it gets neglected. Salt water moisture and small chrome and brass parts do not coexist well. There is a reason that emergency disconnection of your LPI hose is part of dive instruction 101. But if you treat your BCD like you treat your $500 regulators, it doesn't have to be that way. Just disconnect a dump valve after every salt water trip, fill the BCD with warm soapy water and drain it via your LPI, and all will be well.
Sad to say, 90% of the complaints about gear performance that we see in the shop are, shall we say, self-inflicted? It's a fact of diving life, just like it's a fact of flying military jets: every hour cranking and banking means at least two hours of boring maintenance. It's just the price we pay for our joy.
