Well tried to answer a thread asking about the Pro tank 3 and the leaking problem I am having with this unit . I got another one same issue after refill it starts leaking or gurgling and spitting and popping blew the tank out and all the juice was blown . removed and installed another atomizer and that one had no draw and started leaking again even with a new atomizer and replacement unit is this common seems to be the unit wasn't machined currently..how about you guys?
