Yes. PHIX pods can leak due to a plethora of reasons. Fortunately, the leaks don't necessarily mean that the machine is defective. To be precise, the leak is a normal occurrence that you should never worry about. For instance, your PHIX can leak because of direct contact with the liquid. However, PHIX pods leaks can be uncommon if you consider the following techniques:
Wiping off the juice liquid before you decide on inserting it back again into your machine.
Do not puff aggressively, especially on the mouthpiece.
Squeeze gently.
