A leaking pod is one of the most common complaints with any refillable vape. The Caliburn is no exception, though it is usually caused by something simple. A Caliburn most often leaks because of overfilling, drawing too hard, a pod that is not sealed or seated properly, plus sometimes a worn or cracked pod. Nearly all of these are easy to prevent or fix. Here is how to stop your Caliburn leaking.

If a tired pod is to blame, our guide on how long Caliburn pods last helps. Our guide on filling a Caliburn pod shows the correct technique.

First, is it really leaking?

Before troubleshooting, it is worth checking whether you have a true leak or just condensation, since the two look similar but mean different things. A small amount of moisture gathering in the pod bay is normal and harmless, especially after refilling or temperature changes, with a quick wipe of a tissue sorting it. A genuine leak is a steady seepage of e-liquid from the pod or device. If wiping it clean and using the device for a while shows no fresh liquid appearing, it was only condensation. If liquid keeps pooling, you have a real leak to address with the steps below.

The most common cause: overfilling

By far the most frequent cause of leaks is overfilling the pod. When you fill right to the very top there is no air space left, so as the pod warms and pressure changes the liquid has nowhere to go but out through the airflow holes. The fix is simple: fill to around eighty percent and always leave a small air gap at the top. Avoid getting liquid into the central airflow chimney, the tube running up the middle, since anything in there will flood the coil and leak straight out. Filling correctly prevents the large majority of Caliburn leaks before they start.

Drawing too hard

How you vape matters more than people realise. Taking very hard, fast draws pulls more e-liquid into the coil than the wick can absorb, forcing it up into the central air tube where it then drips back, floods the coil and leaks out, sometimes even reaching your mouth as spitback. The Caliburn rewards a slow, gentle mouth to lung draw rather than a forceful pull. If you find yourself getting gurgles, spitback or leaks, easing off the strength of your inhale often cures it immediately. This is a free fix that also improves the flavour and feel of every puff.

Sealing and seating

Two simple mechanical checks catch many leaks. First, after refilling, make sure the silicone fill plug is pushed all the way back into its hole, since a plug that is not fully seated leaves a gap for liquid to escape. Second, ensure the pod itself is pushed firmly into the device, plus on models with replaceable coils that the coil is screwed or clicked in fully and sitting flush. A loose coil or pod lets liquid seep into the chamber and out of the device. A few seconds checking both after every refill prevents a surprising number of leaks.

If your pod is worn or cracked, the Uwell Caliburn collection stocks genuine replacement pods and coils for every model, so a fresh one is an easy fix.

Worn or cracked pods

Sometimes the pod itself is simply past its best. Over time the seals inside a pod degrade, which can cause slow leaks even when you fill and vape correctly, so a pod leaking near the end of its life is a sign to replace it. A pod can also crack if the device is dropped or knocked about in a pocket or bag, where a cracked pod will leak no matter what you do, even if the crack is too small to see. If a pod leaks persistently despite correct filling and gentle vaping, the simplest and most reliable fix is to fit a fresh one.

How to clear a flooded pod

If your pod is already gurgling or leaking from flooding, you can clear it quickly. Remove the pod from the device, cover the mouthpiece with a tissue and gently flick the pod downward a few times to push the excess liquid out. You can also blow gently through the mouthpiece into a tissue to clear the air tube. Then wipe the base of the pod and the device contacts dry before refitting. Taking a few light, gentle puffs afterwards helps settle it. This quick routine clears most flooding and gets you vaping smoothly again in moments.

Related issues and prevention

Leaking often travels with a couple of related problems, so it helps to know the connections. A pod that has been flooding and leaking can also start to taste burnt as the coil struggles, which our guide on why your Caliburn tastes burnt covers in full. And if liquid from a leak reaches the device contacts, it can stop the device firing, which our guide on why your Caliburn is not hitting explains how to sort. Wiping up any leak promptly stops it from causing these knock on issues.

Prevention really is the best cure with leaks, since good habits make them rare. Filling correctly, vaping gently, sealing the pod and using the right liquid handle most of the risk, while keeping the device clean handles the rest. A regular wipe of the pod bay and contacts stops small leaks turning into bigger problems. Our guide on how to clean a Caliburn covers the quick routine, so following it alongside the filling tips above will keep your Caliburn dry, reliable and tasting its best.

The bottom line

A leaking Caliburn is nearly always down to overfilling, drawing too hard, an unsealed fill plug or a worn pod, all of which are easy to fix or prevent. Fill to around eighty percent with an air gap, vape with a gentle draw, push the fill plug and pod fully home, then use a 50/50 nic salt. If a pod still leaks after all that, it is likely worn or cracked, so fit a fresh one. The Caliburn uses leak resistant pod technology, so with correct use, leaks should be rare.
