Kangertech Protank 4 Leaks - advice needed

[stevie1981]

If anyone is still having issues with this tank then try holding the tank upside down after filling then push and screw the cap shut, make sure the airflow is set to open.
You will see air bubbles being pushed up through your juice while you screw it shut. This is what was causing my leaking issues, the trapped air is forcing the juice through the coil wick and it escapes out through the airflow.

Just to add

My Subtank was giving me problems with resistance fluctuations so I decided to use my ProTank4. I didn't like it's RBA so I fitted the Subtank RBA to it. Worked well but it leaked all over the place. Found the solution on the Internet.

Close the airflow before filling using the supid 'side fill' technique. Fill – wipe excess – turn upside down over a tissue – open airflow ... juice will weep out! Why?

No significant leakage after this
