Liquid at the mouthpiece or in the pod bay has one of about six causes, and they are easy to tell apart. Work down this list in order; most leaks are the first two. The advice applies to the refillable pod systems in the Vaperan catalog (2 to 15 mL pods) and, with the differences noted, to disposables.
First: is it a leak or condensation?
Vapor that cools inside the mouthpiece turns back into a few drops of liquid. If you get a drop on the lips after a long session, or a little moisture inside the mouthpiece and nothing in the pod bay, that is condensation, not a leak. Wipe the mouthpiece with a tissue, blow gently through a disposable’s mouthpiece onto a tissue once a day, and carry on. A real leak leaves liquid in the device’s pod bay, on the contacts, or on whatever the device was lying on.
Refillable pod systems: causes in order
- Overfilled pod. Filling to the brim leaves no air pocket, and the next temperature change pushes liquid out through the coil. Fill to the line, or leave about 10% air. The pod system guide shows the fill steps.
- Pod not seated or plug not closed. A silicone fill plug that is not fully pressed in, or a pod not clicked onto its magnets, lets liquid seep. Remove the pod, dry the bay with a tissue, reseat it firmly.
- Flooded coil. Priming a new pod with too many drops, or taking very short sharp puffs, pulls more liquid into the coil than it can vaporize. Symptoms: gurgling and spitting with the leak. Fix: take a few puffs without firing (or with the airflow open) to clear it; blow the pod out onto a tissue from the mouthpiece end; if it keeps happening the coil is worn, replace the pod or coil.
- Worn pod seals. Pods are consumables. After a few weeks the O-rings and the coil’s seal harden; the pod begins to weep at the base. Replace the pod.
- Pressure and heat. Flying, a hot car, or a pocket on a summer day expands the air in the pod and pushes liquid out. Keep the pod less than full before a flight, carry the device upright, and never leave it in a hot car (also for the battery).
- Thin liquid in a high-resistance pod. Very thin (high-PG) e-liquid in a tight coil is drawn through faster than it vaporizes. Match the liquid to the pod: most pod systems are designed for nicotine-salt liquids of normal thickness; check the pod’s resistance and the liquid maker’s guidance.
Disposables
A disposable cannot be overfilled or reseated, so its list is shorter: condensation (by far the most common), heat and pressure (the same hot-car and flight cases), lying on its side for days, and a device that was dropped and cracked. 66 of the 93 disposables we stock have adjustable airflow; closing it fully when the device is in a bag reduces seepage from the airflow slots. A disposable that leaks from the bottom or is wet in the packaging is defective: see the warranty and returns pages, and do not use it.
Cleaning up
Pod bay and contacts: cotton swab, then a dry tissue; a dirty contact is the main reason a pod stops firing after a leak. Mouthpiece: tissue. Never rinse a device with liquid in the pod bay under the tap; water in the bay reaches the battery. Keep leaked e-liquid off skin and away from pets; nicotine absorbs through skin.
Questions
Why is my pod leaking from the bottom?
Usually an overfilled pod, a fill plug not fully closed, or a worn pod. Dry the bay, reseat the pod, fill to the line next time; if it continues, replace the pod.
Why does my vape spit liquid into my mouth?
A flooded coil: too much priming or sharp short puffs. Clear it by blowing the pod out onto a tissue and taking longer, gentler draws.
Why is my disposable vape leaking?
Most often condensation in the mouthpiece rather than a leak. Real leaks come from heat, pressure changes, days on its side, or a cracked device; a device that arrives wet is defective.
Can a leaking vape be fixed?
A refillable one, nearly always: it is the pod or the fill, not the device. A sealed disposable cannot be repaired.
