If your Fat Rabbit RTA is leaking after filling, there are a few things you can check to resolve the issue. First, make sure the AFC piece is properly tightened but not over-tightened, as an improper seal here can cause leakage through the airflow holes. Inspect the AFC piece and the surrounding threading for any damage, cracks, or residue buildup, as gunk can affect the seal and cause leaking. Even though your wicking has been fine in the past, it’s worth revisiting the wicking setup—ensure the cotton is neither too tight nor too loose around the airflow holes, as either can lead to juice leaking when you fill the tank. Check that the top cap is securely screwed on and the o-ring is intact, as any gap here can lead to leaks, especially around the fill port. Additionally, make sure you’re not overfilling the tank, as this can cause excess pressure and lead to leakage, particularly when the AFC is too wide open. Lastly, try closing the AFC slightly before filling to prevent any pressure build-up. If you’ve gone through these steps and the issue persists, it may be worth considering the replacement of certain parts or the entire tank, especially if any components are damaged or worn out. Reaching out to the manufacturer or a local vape shop could help you find the right
replacement parts or a solution to the issue.
