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 resistance.

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.
