Pod leaking? Why it happens and how to stop it

A refillable pod is a tiny tank with a coil built into the bottom. The cotton in that coil holds liquid by capillary action, and the airflow channel runs right next to it. Anything that pushes more liquid into the cotton than it can hold, and it seeps into the air path.

Liquid then runs down to the contacts and magnets where the pod meets the battery. That is why the first sign is often a sticky pod, a gurgle, or the device saying it cannot find the pod at all.

Leaks show up in two places: inside the pod housing and on the mouthpiece. This guide covers the housing. Liquid reaching your lips is covered in our e-liquid in mouth guide.

When the leak happens says more than where it happens. Pick the answer that matches and start with that fix. Most people find their culprit on the first tap.

Do not skip the wipe-down at the end of each fix. Liquid sat on the contacts can short the connection and make the device misbehave long after the leak itself has stopped.

If you have tried every answer below and fresh pods still leak in a day or two, the problem may be the liquid rather than you or the pod. That is covered in the next section.

Pods are built for a gentle mouth to lung draw, roughly like sipping through a straw. A hard, sharp suck creates strong negative pressure that pulls liquid straight through the coil and into the airflow.

If your pod has an airflow slider, open it a notch. A tighter draw means more suction on the coil, and more suction means more liquid pulled into the airway. A slightly looser draw is often the single quickest leak fix there is.

Also check you are not covering the airflow intake with a finger. People do this constantly without noticing, especially on small kits with the intake on the side.

Most refillable pod coils are 0.6 to 1.2 ohm with small wick holes. They work best with 50/50 freebase or nic salt liquids, which are thin enough to wick quickly but thick enough to stay put.

Thick 70/30 shortfills tend to cause dry hits in small pods rather than leaks. But liquids with more PG than VG, some flavour concentrates and very warm liquid straight from a sunny windowsill are all thin enough to slip through the cotton.

Nicotine strength does not affect leaking, but keep it in mind for satisfaction: nic salts in the UK top out at 20mg/ml, and nicotine is addictive whichever strength you choose.

Pods do not last forever. As the coil cotton breaks down and the silicone seals soften, a pod that was fine for a week starts leaking for no obvious reason. That is the pod telling you it is done.

Most refillable pods last roughly a week of steady use, longer on clear liquids and shorter on sweet ones. If your pod is leaking and tasting dull at the same time, swap it rather than fighting it. Our range of replacement pods covers most popular kits.

Run through the checklist below before you bin anything. It catches the quick fixes that are easy to miss.

Here is a scenario that catches a lot of people out. Your pod is a week old, it has been perfect, and now the contacts are wet every morning. You have not changed liquid or how you vape.

Think about what has changed inside the pod rather than outside it. Coils and seals wear in a predictable way, and the symptoms creep in slowly enough that it is easy to blame something else first.

If you guessed right, you have already worked out most leaks for yourself. If you did not, the explanation under the answer tells you why, and the faster fix is usually the cheaper one.
