There is a certain dive shop that sells a lot of tanks and ships them to customers. The tanks are shipped with unattached valve and VIP sticker to be attached by the customer. Are these tanks actually inspected before they are shipped? Who knows what happens to these tanks during shipping?
The valve and VIP sticker are applied by the customer, who in most cases has no training or certification to do so. It is very doubtful they torque the valve properly. Do they lube the O ring and what did they use? WD-40? Who knows. The sticker could even be applied to a different tank that possibly failed a visual inspection before since the customer is trusted to attach the sticker to the tank they purchased.
Marie, I would trust your sticker before I would trust one from DRIS. That is why I won't fill tanks with their sticker. Would you?
My compressor, my rules.
