You really should qualify that challenge. Anyone with a fill whip and high pressure source can easily introduce water into a tank.

We are not talking about adding water to a cylinder under the filling phase... We are talking about a diver being able to add water to a tank when removing the first stage after a dive well the tank has 200 psi in it.. He said tanks "MUST" be returned with 500 PSI in them because that's the law that all diver must surface with at least 500 psi.. He was a A-hole....

... and.... that's why I bought my own compressor. I just took 2 tanks out diving to breath them down prior to hydro (trimix; can't waste it!). Took them down to under 200 before switching to back gas.

Afterward emptied them, removed the valves and shone a flashlight inside. Both were as shiny and clean inside as the day they were made. They are now at the hydro place.

If you get fills, the best advice is to find a great shop (I teach for one on Vancouver Island) and then get fills and service only from them. Obviously not everyone can do this, but dive life is sure nicer if the shop is great.

Note: I bought the compressor (and a booster) because I dive a rebreather and got tired of driving in for 19cf tank fills of O2 and diluent. Again, not everyone is going to go that route.

I'm pretty sure awap was joking.

Yes and no. Shops know perfectly well how water gets into a tank. It occurred during a filling operation. Ops that require 500 psi are just using that to limit dive times or shorten their fill times. But the tank monkey may actually not know any better and is only following instructions.

And some people wonder why some of us don't trust LDS. The pity of it all is that many LDS are honest and trustworthy and always try and do the right thing, unfortunately there is more than just an occasional LDS who is not honest or trustworthy. That tends to taint the whole industry. This is why I did the Dive Technicians course, Hydro and Vis course because I am over trying to find a LDS close enough to me that can do a professional job. Because of the technical nature of diving, it seems that dodgy LDS are not taken to task over ripping uninformed divers off. It is in the interest of divers and honest LDS for this to happen. One must also remember that often the person providing the service on the day are often NOT the owner or a Dive Technician, but simply a poorly informed shop assistant working beyond their skills and knowledge. They often state that "its the law" although untrue, to add weight to their incorrect statement. Sad but true.
 
And that is why I love Bonaire.... I do what I want , When I want... And "NEVER" had a problem with a dive shop... Every place I seem to go... They got some half a$$ rule, "Law" or some kid that just got out of high school telling me my gear is to old ...

Jim,

I didnt realise that if it isnt new and trendy its unsafe to use. Must have missed that in the Tech course, or was it in the unwritten section perhaps? These same smart, full of all knowledge dive shop staff quite often fill tanks in the main shop in front of people. Of course its safe as it has the mandatory safety tape on the floor marking out the danger area (generally 1 metre around the fill area). Good stuff that safety tape, contains all the hazards to the danger area.

My advice is fully support the professionally run LDS and dont go near the dodgy ones, and let everyone know if a LDS is really bad.

What I meant was, he knew you what you were talking about, and agreed with you that it's a stupid policy to insist that renters bring their tanks back with 500 PSI because 'water might get in'. Wet tanks are probably 99.9999% of the time the fault of the filler, not the diver.
