LDS and Nitrox fills.

[Bob DBF]

I have heard of dive shops which won't fill a tank arriving empty because they say it could have been emptied during the dive and water could have gotten in. So they only fill it after a visual inspection.

That's one reason I own a transfer whip. I don't need any crap because I decide to change my own valve or set up doubles. Some people understand DIY and others are d**ks, I just choose to avoid the confrontation.

As to the op, make sure you are talking the same language when you tell some to "do it".

You don't have to go all the way down - If you were to drain an air cylinder to 100 PSI, then top with banked 32%, you'd end up with ~31.7% on a HP fill, or ~31.6% on a 3000 PSI fill.

Don't many shops require you pay them for a VIP if you bring in an empty tank? I think draining the tank first is not good advice unless he knows for sure the shop hit him for a VIP fee.

I've read about shops who will do that ... I even knew one here once that would ... but they went out of business.
