How to Fix a Traditional Sub-Ohm Tank in 2024

A sub-ohm tank is a type of vape tank that's designed for vaping with resistances below 1 ohm. The term "sub-ohm" originates from Ohm's law in physics, which relates the voltage, current, and resistance in an electrical circuit. In the context of vaping, resistance is a crucial aspect because it determines how much heat the coil in the tank will generate when a certain voltage is applied from the battery. That’s why these tanks are popular among vapers seeking large vapor production.

Now, if you're having issues with a sub-ohm tank, the solution will depend on the specific problem you're facing, and that’s what we are going to be covering here today.

How Can a Traditional Sub-Ohm Tank Break?
Here are various reasons why a sub-ohm tank might break or malfunction:

1.Physical Damage: Dropping the tank can crack the glass, damage the threading, or break other components.

2.Wear and Tear: Over time, the O-rings and seals can wear out, causing leaks.

3.Improper Assembly: If the tank is not properly assembled after cleaning or replacing parts, it might leak or not function correctly.

4.Defective Coils: A faulty coil might not heat evenly or at all. Over time, all coils degrade and must be replaced.

5.Cross-Threading: If the tank or coil is screwed on too tight or at an angle, it can damage the threading, making it difficult to unscrew in the future.

6.Temperature Changes: Extreme temperature changes can cause the glass or plastic of the tank to crack.

7.Chemical Reactions: Some e-liquids can react with the plastic of certain tanks, causing them to crack or warp.

8.Over-tightening: Screwing parts of the tank too tight can damage the seals, threading, or even crack the glass.

9.Pressure Changes: Traveling to high altitudes (like in an airplane) can cause changes in pressure that might lead to leaking.

10.Manufacturing Defects: Sometimes, a tank may have defects from the manufacturing process that can cause it to break or malfunction.

11.Overheating: If the mod (the device to which the tank is attached) malfunctions and overheats, it can potentially damage the tank or its components.

12.Electrical Issues: Short circuits or other electrical issues within the coil or tank can lead to malfunctions.

13.Improper Cleaning: Using harsh chemicals or not drying parts properly can lead to damage over time.

14.Excessive Force: Using too much force when opening, closing, or adjusting the tank can lead to breakage.

How to Fix a Sub-Ohm Tank
Below are some common issues with sub-ohm tanks and the potential solutions:

1.Leaking Tank:
·Ensure that all the parts are screwed together tightly.
·Check the O-rings and seals for any damage and replace them if necessary.
·Make sure the coil is properly seated and screwed in.
·If your coil is old or burnt, replace it.
·Avoid overfilling the tank.
·Close the airflow when filling the tank.

2.Gurgling Sound or Spitback:
·Ensure the tank isn’t overfilled.
·Check if the coil is flooded with e-juice. If it is, take the tank off the mod, place a paper towel on the airflow and blow into the mouthpiece without firing.
·Replace a saturated or old coil.
·Check the e-juice’s VG/PG ratio. High PG liquids tend to be thinner and might flood the coil easier.

3.Burnt Taste:
·Prime the coil properly before use by dripping e-juice directly onto the cotton wicking material.
·Start at a lower wattage and gradually increase.
·Replace old or burnt-out coils.
·Ensure the juice flow holes on the coil are not obstructed.

4.Not Producing Vapor:
·Ensure that the battery/mod is charged and turned on.
·Check if the coil is burnt and replace it if necessary.
·Ensure that all connections are clean and making contact.
·Check the mod's settings to ensure they are appropriate for the coil's

5.Tank Getting Too Hot:
·Take breaks between puffs to let the tank cool down.
·Ensure proper airflow. Open up the airflow control more.
·Reduce the power setting on your mod.
·Make sure you're using a coil within its recommended wattage range.

6.Airflow Issues:
·Check for obstructions in the airflow path.
·Clean the tank thoroughly, especially the airflow control ring area.
·Replace damaged O-rings.

7.Thread or Connector Issues:
·Clean the 510 connector on both the tank and mod.
·Avoid over-tightening the tank onto the mod.
·Check for damages on the threading and consider replacing parts if they are stripped.

8.Cracked or Broken Glass:
·Many tanks come with replacement glass, or you can simply purchase one separately.
·Remove the damaged glass and replace it.

Note: If after trying the above steps your tank still doesn't work, it might be time to consider purchasing a new one. Always ensure that any modifications or repairs you make/do to your vaping equipment are safe and in line with the manufacturer's guidelines.

General Sub-Ohm Tank Maintenance You Need to Know
Regularly clean your tank to avoid build-up and potential issues. This involves disassembling it and cleaning all parts with warm water (avoid using soap). Let all parts dry thoroughly before reassembling and using. Also, always have replacement O-rings, seals, and coils on hand. These parts wear out or get damaged over time, and having spares can save you a lot of hassle.

To reduce the chances of breaking a sub-ohm tank:

·Always handle it with care to avoid drops or impacts.
·Properly assemble and regularly maintain the tank.
·Avoid extreme temperature changes.
·Use e-liquids that are compatible with your tank material.
·Don't over-tighten components.
·Replace worn-out or damaged parts promptly.
