I bought an AL80 tank at the LDS last week. Besides hooking up the regulator and taking a few test breath, never dived with it. I took it back trying to exchange for a different color and was told that they cannot take it back BY LAW. They also said they cannot take back any life-support equipment (such as the regulators, which he mentioned clearly) by law.
Does anybody know if there's such law here in the US? Where can I find it (the law)?
