How To Stop Your Tank From Leaking

    It can be extremely irritating if you have a leaking tank, however most of us have experienced the frustration at least once. Losing your expensive e-juice is bad enough, but it’s even worse when you don’t seem to be able to stop the leakage from occurring. The good news is that there are several ways you can deal with the problem.

    Filling Your Tank Incorrectly

    By far the most common cause of tank leakage is incorrect filling, which is good news since it’s easy to rectify. Tanks have a central air flow tube called a chimney which runs through the tank’s body to the drip tip. Although all vapers know that they’re supposed to avoid the chimney when filling the tank, many accidentally get their e-juice down the tube and this leads to leaking. If your e-liquid somehow gets into your chimney while filling your tank, you should use a paper towel to clean the chimney before vaping. If you avoid overfilling the tank that will also help since an air pocket at the top of the tank creates a vacuum which stops the e-juice from coming out.

    Damaged O Rings

    This is another common cause of leakage. If you’ve taken care to fill your tank properly and are still have problems with leakage you should take your tank apart and examine its O rings. If there are broken, worn or missing, the air seal of your tank won’t be working properly and you’ll need new O rings (in the right size, of course.)

    Poorly Fastened Tanks

    Another simple problem to rectify is a tank which isn’t property fastened together. If the tank isn’t screwed on tightly enough or is accidentally cross-threaded, it’s possible for e-juice to leak out. Check your threads are correctly threaded and that the tank is screwed on properly (although not too tight). Sometimes, it’s impossible to screw the tank on properly as the threads have become worn. If this occurs, you’ll simply need to get a new tank.

    Poor Positioning

    Some tanks don’t cope well with being stored horizontally, and e-juice may leak through the airflow holes if left in that position for any length of time. Try standing it up vertically instead, especially when charging overnight.

    Coil Issues

    Occasionally, it is the coil which is at fault because of a manufacturing flaw. You may need to buy a new coil and try replacing the one that you have to see if it solves the problem.

    Dirty Tank

    Sometimes, when a tank hasn’t been cleaned for a while, old e-juice will build up a residue inside the tank’s components and this can end up causing leakage. Take your tank apart, wash it with cold water and leave to dry completely before putting it together again. If you like, you can give it a deep clean by separating the tank parts and washing them all with detergent and water.

    Damaged Tank

    Sometimes, your tank will have a crack or damage that you haven’t noticed. A bit of bent metal or a narrow crack in the glass will mean that the tank isn’t airtight any more and the e-liquid will leak out.

    Incorrect PG/VG Ratio

    If you are using a very power hungry coil head, any e-juice which is less than 70% VG content is likely to be too thin and will end up leaking through the large juce port.

    Missing Top Cap

    As tanks are pressurized, if the tank has no top cap e-liquid will start to leak from the airflow holes. Always ensure that you only ever leave the top cap off for an extended period if the tank is empty.

      How To Clean A Vape Tank

      Be Sociable, Share!

        Keeping your vape tank clean is one of the best ways to make sure that your flavour remains good and that your vaping experience is as good as it can be. If you allow grime and residue to build up on the inside of your tank, you’ll find that eventually your e-juice will start to develop an unpleasant taste, and your e-cigarette’s performance will begin to deteriorate. You can rectify this by maintaining your vape tank regularly and keeping it in good condition.

        Here are some of the quickest and easiest ways of cleaning a vape tank.


        This is a common and simple way of keeping your vape tank clean. First, take your tank apart into as many pieces as it can break down into. You will also need to remove the O rings carefully as much of the old flavour will be trapped there. If you’re using a device that has replaceable coil heads, remove the coil head before you clean. If it’s still in reasonable condition you can re-use it, but if flavour is a problem, replacing it with a new coil head is the best idea Fill a bowl with water and microwave it for around 2 minutes while you rinse your tank parts in the sink. Once the water is warm, take it out of the microwave and put your tank pieces into it. Allow the tank to sit in the water until it cools then rinse once more under the sink. Dry the tank carefully with a paper towel then leave to fully dry. You may use a small cleaning brush to keep your tank clean. These are available cheaply or alternatively, you can use a child’s toothbrush instead.

        Soaking In PG/VG

        Should you prefer not to use tap water, you could soak the tank in PG instead. Just fill the bowl with unflavoured PG and allow your tank to soak. While you could use VG instead, this is a thicker liquid so isn’t as effective when cleaning tanks. After your tank has soaked for a while in PG, put it upright on a napkin and allow it to drip dry.

        Other Rinse Agents

        There are a number of other substances which you may have in your home which can be used as an alternative to PG or water.

        Vinegar – its acidic properties make it great for cleaning tanks, however you need to rinse it thoroughly as otherwise its smell will linger.

        Baking soda – this will get your tank sparkling clean.

        Ethanol – grain alcohol is another excellent cleaning substance but don’t confuse it with Isopropyl alcohol.

        Dishwashing detergent – remember to rinse well with water afterwards.

        Ultrasonic Cleaners

        The most thorough cleaner of all is an ultrasonic cleaner. Usually used for cleaning precious metals and jewellery, vapers can also use it to clean an atomizer and in fact, some vaping companies have now started making specific vaping versions!

        Change The Coil Head

        If you’ve tried all of these methods and your flavour still isn’t quite right, try changing your coil head. You can either buy a fresh one or build your own. If you already use a rebuildable atomizer though, try taking the cotton out, burning off the remainder of the e-juice and then rinsing first before throwing away the coil. You can brush the coil with a toothbrush and see if it makes any difference.

        There are many excellent ways of cleaning a vape tank, although some methods are easier and quicker than others. Experiment with the various methods here and see which suits your needs best.
