I have refilled my tank twice and each time the liquid leaks into the base and through the airflow holes. The first time, I was using the coil that came with the tank but the second time I was using one from a pack of replacement coils. The replacement coils are official Nautilus BVC replacement coils from Aspire. While I am using the tank, no liquid leaks and it works fine but as soon as I loosen the base to refill, it comes out through the airflow holes. This leaves me with having to do a lot of clean up before I can use it again. I have made sure that the tank is sealed tightly but not too tight.
Am I doing something wrong or is it possible the product is defective?
