Why Is My Vape Leaking? Here’s How to Fix It for Good

A simple guide to stopping leaks and keeping your device clean.

Ponder this: This sticky smear is in your pocket when you reach for your vaporizer. Some e-liquid spills from the mouthpiece or base. Does this sound familiar? Despite their inconvenience, vape leaks are prevalent. Repairable most of the time.

This thorough lesson will show you the most common vape leak causes, the fastest fixes, and the best ways to prevent them. Everything for pod systems and vape kits is here.

What causes vape leaks?

Start with basics. A leak occurs when e-liquid spills from a pod or tank into the airflow chamber, battery connector, or pocket.

Most common reasons:

1. Overfilling the Pod or Tank

Filling it to capacity may be tempting, but it could cause issues. Airspace is needed for most vapes. If you fill it too high, pressure will force liquid out through airflow system openings.

Fill to the line or just below it, leaving some airspace.

2. Broken or misplaced O-Rings

Those small rubber bands that come with your gadget? They are crucial for seal waterproofing. If these elements are broken, missing, or misaligned, your tank or pod may leak.

Take apart your device and check the seals to fix it. Replace cracked or missing O-rings. Extras are usually included or available online.

3. Excess or excessive breathing

Drawing gently and steadily from devices, especially MTL pods, is ideal. Quick, forceful breaths can fill the coil with liquid, causing flooding and leaks.

I advise against huffing. Draw softly and evenly to achieve the greatest taste and avoid leaks.

4. Unsuitable e-liquid for product

Each juice has unique qualities. A pod designed for thicker VG-heavy liquids may leak with a high-PG e-liquid.

Solution: Choose a device-compatible drink. Sub-ohm kits use 70/30 VG liquids and low-power pods use 50/50 or nicotine salts.

5. Coil issues or improper setup

Vapor can leak from an improperly placed pod or coil.

Correction: Don't overtighten screws when installing coils. Check that the pods fit snugly and align with the device. Recheck after each filling.

6. Temperature changes

Leave your vaporizer in a hot car or light window? Because e-liquid swells, it can leak from seals when hot.

Always store your device in a cold, dark place while not in use.

The best leak repair method

If something goes wrong, cleanup is simple.

Disassemble your item.

Remove the tank, pod, and battery.

Eliminate dust.

Use a gentle cloth or paper towel to clean. Dampen it with warm water (not the battery port) to remove sticky places.

Examine ventilation and charging ports.

Use a Q-tip to clean the charging port and gently blow into the airflow aperture.

Let it dry naturally.

Pause, then reassemble.

FAQs

1. Why is my vape leaking out of the air holes?

Vape leaking from air holes is often due to overfilling the tank, a worn-out coil, or improper sealing. When the tank is too full or the coil is flooded, excess e-liquid escapes through the airflow vents. Using thin (low VG) e-liquids can also cause leaks in tanks not designed for them.

2. How to fix a pod leaking from the bottom?

To fix a pod leaking from the bottom:

Remove and clean the pod and battery contacts with a dry cloth.
Check if the coil or pod is properly seated.
Avoid overfilling and make sure the rubber seals are intact.
Replace the pod or coil if it’s old or damaged.
Store your device upright to prevent pressure buildup.

3. Is a leaking vape dangerous?

Minor leaks are usually not dangerous, but:

E-liquid is toxic if ingested, especially to children and pets.
Leaks can damage your device if liquid reaches the battery area.
If the device is leaking badly or consistently, stop using it until the issue is fixed to avoid possible short circuits or malfunctions.

4. Why is my vape leaking juice in my mouth?

This is called “spitback” and happens when e-liquid pools on the coil and heats up too quickly. Causes include:

Drawing too hard or too quickly.
A flooded coil.
Overpriming or overfilling.
Using low wattage with a high-power coil.
To fix it, clear excess liquid from the coil, take slower draws, or replace the coil.

5. Why is my Smok vape leaking from air holes?

Smok vapes can leak due to:

Loose or worn-out O-rings.
Incorrect coil installation.
Overfilling or filling the tank too fast.
Using very thin (high PG) e-liquids.
Make sure all seals are intact, coils are properly tightened, and avoid overfilling.

6. Why is my vape leaking out of the air holes?

(Repeated question—same answer as #1):
It typically leaks from air holes due to flooding, overfilling, worn seals, or using the wrong e-liquid type. Keep the device upright, avoid overfilling, and replace old coils regularly.

7. Why is my cart leaking from the bottom?

Cartridges (carts) can leak from the bottom due to:

Overfilling or high temperatures causing expansion.
A cracked or damaged cartridge.
Poorly fitted or faulty seals.
Storing the cart horizontally or upside down.
Check for visible damage, store upright, and replace the cart if needed.
