Fill Lines Can Differ Per Tank

Every vaper knows that he or she needs to properly fill the tank in order for coils to become properly saturated and for each hit to be perfect. But how do you properly fill a tank? Surprisingly, this is something many vapers do incorrectly. When filling is done incorrectly, problems from dry hits to leaky tanks occur. Filling tanks differs for each and every device you use in small ways, but the general procedure remains the same.

There is one absolutely critical piece of terminology you need to remember when you’re filling up your tank with vape juice. That one term is “fill line”. Many don’t even realize there’s a fill line on tanks, and therefore inadequately fill them with e-liquid. There should be a visible line on the tanks that indicates not to fill past that point. This line is in place due to the physics behind vaping. Clearomizers and atomizers rely on the vacuum created when the tank is sealed to keep liquid from falling out of the tank completely. If the tank in a bottom-filling device is overfilled, then it’s likely that some liquid will spill over the edge and drain down the center channel. This in turn will flood the tip, leaving a strange taste in your mouth. Top fill tanks need air in the very top of the tank to maintain a space for airflow and to keep gravity at bay. It’s imperative to remember that fill lines will certainly differ with every tank you use. For example, fill lines in MODs will be in a different location relative to those in an e-cigarette. Even within device types, there’ll be differences in fill lines. An RBA will’ve a fill line at one point, while an RDA won’t.

Fill lines in e-cigarettes are usually very noticeable, but some designs may not have them. If there’s no fill line on your e-cig, then use the general rule that you shouldn’t fill past the bottom of your wick. The bottom of your wick should be located after it leaves the center post. Fill the tank up to a few millimeters below that and you should be good to go.

In portable vaporizers, vape pens, and MODs, you’ll need to consider whether your tank is a top-filling tank or a bottom-filling tank. If it’s a bottom-filling tank, you’ll need to first unscrew the base from the tank and turn the whole thing upside down. You should be able to locate a fill line. If there’s no fill line, just make sure your e-liquid isn’t high enough that it’ll flood into the center post. Top fill tanks just need that little bit of air at the very top to maintain airflow. MODs will usually need significantly more e-juice due to the massive amounts of vapor they produce. Don’t be alarmed if you’re filling your tank up for much longer than in any other type of device.

Filling up tanks is probably not something you thought would take finesse, but it’s definitely helpful if done correctly. Make sure you pay special attention to the fill line built into the tank, and keep a steady hand when filling. Incorrect filling can lead to leaky tanks or strange flavors in your mouth, both things that can be easily avoided. Make sure you consider what type of tank you have, its size and shape, and where the fill line is located. Fill it up and have a good vaping session - you deserve it.
