Also relating to "tank cracking", pods are designed so as to eliminate, or minimize connection to metal. The only tank I had crack was due to the poly-carbonate getting fused to the metal base.
That was a chemical to physical reaction of the juice on the materials. In essence the acid of the juice caused a chemical fire, melted the poly-carbonate which then welded itself to the metal from the heat.
Since pods now lean toward limited connection points, agree with @5150sick , you'll likely be fine.
