Pod System Leaking

If you use a pod system chances are you’ve asked yourself the question, Why is my pod system leaking?. Let’s be honest, any of us that use pod systems know this constant headache of leaky pods.

I have come to the conclusion that if I’m going to test a new pod system, I pretty much assume it’s going to leak, at least a little bit. At least for the cheaper pod systems ($30 and under.) The higher end systems, we should expect a little more from. If you are looking for a pod system that is higher end and doesn’t leak, check out the Mi-Pod. It is worth the extra bucks to retain your sanity.

Maintaining the assumption that it’s going to leak going into it helps to some degree with the frustration levels. Ya know, set the bar low, you won’t set yourself up for disappointment. It reminds me of when I met my wife. Because we met at a time in our lives when we were a bit older and set in our ways, at our first sit down dinner date, we discussed expectations and not setting the bar too high for each other. It’s been marital bliss ever since and the bloom has not left the rose. 🙂

Various Pod Systems

Over the last few years, I have used and tested many pod systems. Too many to count actually, and a majority of them leak at least little and need constant attention with q-tips or paper towels to keep them working. If we don’t keep the inside area free of liquid where the pod inserts, it can compromise the system and cause it to short out or stop working.

In my experience of using hundreds of pod systems, most of the pods themselves have one thing in common. Their conceptual design. That design being, a reservoir that holds juice and inside the reservoir, an atomizer apparatus that vaporizes the liquid. Additionally, various plastic and metal parts that make up the pod. Some of these parts are put together well and some not so well and can attribute to some pod leakage. It is possible to get a bad pod. A bad pod can definitely get your frustration levels rising.

Much of the pod system leaking has do with a multitude of factors and if we are aware of them, we also have less frustrations. Below I’ll attempt to highlight some of my experiences with the various pod systems and in turn, hopefully help someone with this plaguing issue.


#1 Reason for Pod System Leaking… Chain Vaping

First I’d like to point out the #1 reason I have found for the pod system leaking. Chain Vaping (hitting the pod system over and over in one smoke session to where it heats up considerably.) When we take a puff off the pod system, it draws air through the system and in turn creates a vacuum and pressurizes the liquid and air in the pod.

If we chain vape a pod system, not only do we create more of a vacuum but we also generate more heat on the pod itself. By doing so, we heat up the liquid which makes the liquid more viscous (runny) and can result in the vacuum forcing a larger amount of liquid through the cotton (or ceramic) wick. Then flooding in the air chamber can happen and in turn, “spit back.” Spit back is where we have ejuice running out the mouthpiece and into our mouths.

Along with creating spit back, the heating of the juice for prolonged periods can cause juice to seep through the fill plug on the bottom or side and also through any other crevices that may not have been 100% sealed at the factory.

Keeping our puff sessions to a limited number of puffs and avoiding the over-heating of the system, should lead to less frustrations. If you are the type of vaper like me, and like to take a good number of puffs each time, keep two systems or more handy (I usually keep four at a time on my desk and rotate through them.)

#2 Reason for Pod System Leaking… Too thin of Juice Blend

I’ve tried different ejuice blends 30/70, 40/60, 50/50 and High VG in pod systems. The best blend for non-leaking pods is going to be High VG. Because VG is a thicker compound, the ending result is the ejuice is thicker. Thicker ejuice makes it harder to leak. The 30/70 PG/VG mix would be the next choice for a less leaky system and the ejuices thin out as the PG increases. The thinner the ejuice the more chance of leaking. It just the way it is and we have to deal.

It’s helpful to know how these different PG/VG blends affect your vape experience. VG is the thicker compound and the most noticeable factor to vaping is the vapor production. The higher the VG, the more vapor the juice will produce. The caveat here is that VG is not a flavor booster but more of a flavor muter and is also smoother on the throat hit.

On the other hand, the PG in vape juice is more of a flavor carrier and harsher on the throat hit. So usually ejuices with a higher PG content will be more flavorful. When it comes to salt nic ejuices, more PG becomes necessary. Because salt nic ejuices have a higher nicotine content, a good portion of a 30ml bottle is taken up by nicotine. So, more PG is needed to boost the flavor to make up for the lost bottle space. Also, because of the higher PG content, the juice is thinner making pod systems more susceptible to leaking with higher PG content ejuice.

As you can see, the juice you use plays a big part. I think it’s funny that some of the pod system manufacturers out there state on their manuals 30/70 PG/VG juice recommended. If you like the 50/50 Salt Nic juice, which I do and is the most popular PG/VG blend for salt nic juices, you can pretty much guarantee some seepage. I don’t know the actual percentage of pod system users that use Salt Nic juice but I would guess at least 50% use salt nic ejuice. So pod systems that recommend 30/70 PG/VG would alienate a good portion of users.

#3 Reason for Pod System Leaking… Letting it sit

Letting your pod system sit in a drawer and not use it for a few days will promote leaking. Because these systems become pressurized through usage, leaving them sit and evaporating the standing liquid that soaks into the atomizer, can cause gradual seepage. I have tested this with a variety of pod systems namely the OneVape Lambo (Lambo is actually a good system with minimal leaking until you let it sit for few days), SMOK Fit and Infinix, SMOK Nord and Novo, Suorin Drop, Air and iShare to name just a few.

Additionally, letting your pod system sit in a car in the heat will almost always guarantee leaking. Same goes for leaving it in the cold. Dramatic temperature changes to pod systems does not serve them well.

#4 Reason for Pod System Leaking… Not Keeping the Juice Level Full Enough

As explained earlier, pod systems use a pressurization system in which the system pressurizes the juice inside the pod when using. Keeping the juice level at or above 50% at all times will help prevent excessive leaking. I do know it’s tough to do especially if you take your pod to work and don’t want to mess bringing juice also.
