Why Is My Cart Leaking from the Bottom?

Vaping has become increasingly popular in recent years, but users sometimes encounter a frustrating problem: leaking carts. This can be a nuisance and waste of precious oil, not to mention a potential health hazard.

In this article, we will explore the various reasons why your cart might be leaking from the bottom and provide some tips on how to fix the problem. We will also discuss some safety precautions to take when dealing with a leaking cart.

By the end of this article, you will have a better understanding of the causes and solutions for leaky carts, and you can enjoy a more reliable and enjoyable vaping experience.

 

Why Is My Cart Leaking from the Bottom?

 

Vape cartridges can leak for several reasons. Overfilling the cartridge creates pressure and forces oil out, especially when heated. Using too high a temperature can also thin the oil and cause leaks. Damaged cartridges with cracks or dents will naturally leak. Finally, improper storage, like laying the vape on its side, can allow oil to pool in the mouthpiece and leak out. To prevent leaks, follow filling recommendations, use the correct temperature settings, handle cartridges with care, and store them upright.

Connection issues

This could be due to the cart not being screwed on tightly enough to the battery, or it could be screwed on too tight and causing cracks. Make sure the cart is finger-tight to create a good seal.

Incorrect Threading with the Battery

If the threading on your cartridge doesn’t properly align with the battery, it can create gaps where the e-liquid can leak out. Ensure that the cartridge is securely and correctly attached to the battery.

Overtightening the Cart onto the Battery

While it’s essential to screw the cartridge onto the battery snugly, overtightening can distort the seal and cause leaks. Tighten the cartridge just enough to create a secure connection without applying excessive force.

Clogged Cart

A clogged cartridge can lead to pressure imbalances, causing e-liquid to leak out from the bottom. Regular maintenance, such as cleaning the cartridge and ensuring proper airflow, can help prevent clogs.

Overheating

Excessive heat can thin out the e-liquid, making it more prone to leaking. Avoid leaving your device in hot environments or using it continuously for extended periods, as this can cause overheating and subsequent leakage.

Overfilled Cartridge

Filling your cartridge beyond its capacity can result in leakage, as there’s no room for expansion when the liquid heats up. Follow the manufacturer’s guidelines for filling the cartridge to prevent overfilling.

Improper Capping

If the cap or seal on the cartridge is damaged or not securely in place, it can allow e-liquid to seep out from the bottom. Ensure that the cap is properly sealed after filling the cartridge.

Incorrect Coil Installation

While there are many reasons your vape might be acting up, a sneaky culprit could be a wonky coil. Vape coils are those little workhorses that heat up your e-liquid, creating the vapor you inhale.  But if a coil isn’t installed just right, it can disrupt the delicate balance and lead to leakage.

Here’s how to make sure your coil’s not the leak-causing foil:

  • Seal the Deal

Most coils have silicone rings that act like tiny gaskets, preventing leaks. Double-check that these rings are snug and properly seated on the coil.

  • Glass Act

For vapes with glass tanks, ensure all the components fit together securely. Tighten things up, but be gentle! Over-tightening can damage the silicone seals, defeating the whole leak-prevention purpose.

  • Screw It Up (Right!)

If your coil screws in, make sure it’s perfectly aligned before tightening. Misaligned coils can leave gaps that become express lanes for e-liquid to escape.

By keeping these coil installation tips in mind, you can keep your vape functioning smoothly and leak-free!

Physical Damage

Damage to the cartridge, such as cracks or breaks in the casing, can compromise its integrity and cause leaks. Inspect the cartridge for any visible damage and replace it if necessary.

 

How to Fix Cart Leaking from Bottom?

 

 

Fixing a leaky cart depends on the severity of the leak and the cause. Here are some steps you can try:

  • Check for loose connection

Sometimes a leaky cart is simply due to a loose connection between the cartridge and the battery. Make sure the cart is screwed on securely, but avoid over-tightening.

  • Store upright

Always store your cart upright when not in use. This helps prevent the oil from pooling in the mouthpiece and leaking out.

  • Use the right temperature

Vaping at a high temperature can thin the oil and make it more prone to leaking. Try using a lower voltage or wattage setting on your battery.

  • Don’t Overfilling

When refilling your vape cart, it’s crucial to avoid overfilling beyond the designated maximum fill line. Exceeding the maximum fill line can cause the vape cart to leak. This happens because the excess juice has no place to go but out through the airflow holes or the mouthpiece seal. Leaking not only wastes your vape juice but also creates a mess and can damage your device over time.

 

If the leak persists, it’s likely a more serious issue and the cart may not be salvageable. Here’s what to do:

  • Don’t use the cart

A leaking cart could potentially damage your battery and could be dangerous to use. 

  • Consider contacting the manufacturer

If you purchased the cart from a reputable dispensary, they may be able to offer a replacement.

 

Here are some additional things to keep in mind:

  • Quality matters

Low-quality carts are more likely to leak. If you’re having recurring problems with leaks, it might be worth investing in higher-quality cartridges.

  • Not all leaks are fixable

If the cart is cracked or damaged, there’s no way to fix it. You’ll need to dispose of it safely. 

 

How Do I Stop My Cart from Leaking?

Check the connection: Make sure the cartridge is screwed on securely to the battery. A loose connection can allow liquid to seep out.

Use the right temperature: Vaping at a high temperature can thin the oil in the cartridge, making it more likely to leak. Try taking puffs at a lower voltage or wattage.

Avoid chain vaping: Taking puffs too frequently can overheat the cartridge and cause leaks. Take breaks in between puffs to allow the coil to cool down.

Inspect for damage: Look for any cracks or damage to the cartridge itself. A damaged cartridge may not be salvageable and should be replaced.

If you’ve tried all of these and your cart is still leaking, it might be best to replace it.  Unfortunately, some carts are just duds.

 

Why is My Cart Leaking out the Top?

Leaking from the top of a vape cartridge can be caused by several factors. By addressing the following causes, you can reduce or eliminate leaks from the top of your vape cartridge.

  • Overfilling

Overfilling the cartridge can cause the liquid to overflow and leak out the top. Make sure not to fill the cartridge beyond the recommended level.

  • Temperature Changes

Extreme temperature fluctuations can cause the liquid to expand and contract, leading to leaks. Try to keep your vape pen at a consistent temperature, avoiding both high heat and freezing conditions.

  • Improper Storage

Storing the vape pen upside down or on its side can lead to leaking. Always store your vape pen upright to prevent leaks.

  • Faulty Cartridge

Sometimes, the cartridge itself may be defective. Check for any cracks or damage. If the cartridge is faulty, consider replacing it.

  • Incorrect Voltage/Wattage

Using the wrong voltage or wattage can cause the liquid to thin out and leak. Ensure you are using the correct settings for your cartridge.

  • Clogged Airflow Holes 

If the airflow holes are clogged, it can create pressure that forces the liquid out. Regularly clean the airflow holes to prevent clogging.

  • Drawing Too Hard

Taking hard draws can create too much pressure, causing leaks. Try to take gentler puffs to reduce the pressure build-up.

 

How to Fix Wax Coming Out of a Cart?

To fix wax leaking from a vape cartridge, avoid inhaling too firmly as it can force oil out of the wick; instead, take long, slow puffs. Use high-quality cartridges made from durable materials like stainless steel, ceramic, and borosilicate glass, and ensure you’re using the right type for your concentrate. Avoid overfilling the cartridge to prevent forcing oil into the coil assembly, and always store cartridges upright to maintain the vacuum and prevent leaks.

  • Don’t Inhaling Too Firmly

Using too much air pressure while puffing is a common reason for wax or oil to leak from a cartridge’s mouthpiece. When you’re new to vaping, remember that harder puffs won’t increase vapor production; only increasing your device’s power can do that.

To maximize vapor without changing power, take long, slow puffs. If you’re using a puff-activated battery, use just enough air pressure to activate it. If you have a manual fire button, puff lightly to draw vapor into your mouth. Excessive air pressure forces oil out of the cartridge’s wick and into the coil assembly, leading to leaks.

  • Using a High-Quality Cartridge

Not all vape cartridges are created equal. Some are more reliable than others. If leaks persist despite your efforts, consider switching to a higher-quality brand. We manufacture cartridges with top-quality materials like stainless steel, ceramic, and borosilicate glass to ensure consistent performance from first to last puff.

  • Using the Right Type of Cartridge

Using the right cartridge for your concentrate is crucial. Oil-based concentrates require cartridges with ceramic wicks, like our Easy-Fill and Titan 2 Cartridges, which are designed for thick oils. Wax-based concentrates need cartridges like our Wax Tank, intended for solid concentrates at room temperature. Using the wrong type leads to clogs and leaks.

  • Don’t Overfilling the Cartridge

Overfilling can cause oil or wax to leak from the mouthpiece. Most cartridges appear to have room after adding the correct amount of oil, but the chimney or mouthpiece takes up space when closed. Overfilling forces oil into the coil assembly, causing leaks. Our Easy-Fill Cartridge has a clear maximum fill line to prevent this. Use measuring tools and know your cartridge’s capacity.

  • Storing the Cartridge Correctly

Store filled cartridges upright unless sealed in the original package. Once the silicone caps are removed, a weak vacuum maintains the oil in the cartridge. Storing it on its side breaks this vacuum, causing leaks through the wick.

 

What Are the Symptoms of a Bad Cart?

Leaking: A clear sign that something is wrong with the cartridge itself. Leaking oil can damage the battery and cause shorts.

Burnt taste: This can happen if the coil is burnt out, or if the oil is too old or has been stored improperly.

Off-brand packaging: Legitimate cartridges will have cannabis packaging that is professional-looking and includes information about the product, such as the strain, THC content, and manufacturer.

If you experience any of these symptoms, it’s best to err on the side of caution and throw the cart away.  Using a bad cart can be dangerous, so it’s not worth the risk.

 

How to Clean a Leaking Cart?

 

Why Is My Cart Smoking from the Bottom?

When your cartridge smokes from the bottom, it often indicates that the tank is nearly empty. Ensure the oil level is sufficient near the tank’s bottom, where it meets the battery and tends to heat up. Cleaning the toke hole with a small pipe brush can help remove residue.

Some cartridges use cotton felt to hold heated oil near the heating element, while others, typically more expensive, use a ceramic piece for heating without cotton felt. Felt cartridges are prone to developing a burnt taste over time and should be replaced if they start tasting bad, unless you can dismantle and clean the cotton/felt inside.

 

Final Words

Leaking carts can be a frustrating and messy problem, but by understanding the causes and following the tips in this article, you can prevent or fix the problem and get back to enjoying your vape. Remember to always use caution when handling a leaking cart, and dispose of it properly if it is damaged or cannot be repaired. With a little knowledge and care, you can keep your vaping experience safe and enjoyable.
