How to Clear a Flooded Tank

You must be over 18 to purchase products from E-Cigarette Direct

Quick tips on how identify and solved a flooded vape tank

Even experienced vapers sometimes get a flooded vape tank or clearomiser. Fortunately, it’s usually easy to fix. This guide will explain what causes a flooded tank, and what to do about it if it happens to you.

What is a flooded tank?

The term ‘flooded vape tank’ refers to e-liquid gathering in the airflow. It has also been used to describe e-liquid leaking onto the battery connection.

How do you know if you have a flooded tank?

If you inhale on your tank and hear a gurgling noise, you’ll know you’ve got a flooded tank. Alternatively, you may find e-liquid is leaking from the airflow. It’s not just the gurgling noise that is annoying – typically, you’ll also get less vapour, a poor throat hit and reduced nicotine delivery.


What causes a flooded tank?

Any of the following can cause a flooded tank:

1. Firing up your vape before inhaling. Some vapers like to do this to avoid spit back, but it can lead to vapour condensing in the mouth piece.

2. Not changing your coil regularly. As the coil ages, it starts to lose its ability to soak up and vaporise e-liquid. This inefficient operation can lead to e-liquid flooding the mouth piece.

3. Not inhaling correctly. While most smokers take short sharp drags, vaping requires longer, slower drags, with little oxygen taking in.

4. Filling your tank incorrectly. The key here is to ensure your e-liquid does not go down the center tube of the tank. Many modern tanks are built to ensure this doesn’t happen, but its still possible to get e-liquid down the centre tube with older designs.

5. Over-filling. Again, while many tanks have been designed to be fool-proof, it is still possible to over fill some models. Before filling your tank, check to see if there is a line marking where it should be filled too.

6. Using too low a power setting. If you set the power too low, your device will not vapourise all the e-liquid it is absorbing. The best port of call for setting the wattage correctly is usually the instructions that come with the device. These often give an ideal wattage range for the device and tank you are using.

7. Damaged O-rings. Many tanks contain O-rings, which create a seal within the tank. These can get damaged. Fortunately, many kits and tanks now come with replacement O-rings.

8. Loose tank connections.

How do you clear a flooded vape tank?

Hopefully you’ve already got some ideas from the causes above, but if not, here’s a checklist of things to do.

1. Remove the mouth piece from the tank and blow through it.
2. Clean the mouth piece with a cotton bud or tissue.
3. Remove the tank and give it a flick.
4. Check the O ring in the tank is not broken.
5. Clean your tank as described here.
6. Change the coil.

This should work for most tank designs, but do bear in mind that there are often quirks that come with different tanks. If the above doesn’t work, do try contacting your supplier, as they often come to know the different quirks that come with different tanks, and how to fix them!

You Must Be Over 18 to Buy From E-cigarette Direct

Why do I have to prove my age?

To our website you look under 18.

So, as a responsible retailer, we need to check your age.

You'll only need to do this once and it takes less than a minute.

Our age verification system is quick and easy to complete. Simply enter your date of birth, and our system will use the information from your order to do the rest.

On rare occasions, you might find that you don’t succeed on first try. Don’t worry - our super-friendly customer service team is on hand to ensure that, as long as you are 18 or over, you can still get your vaping supplies!

Once you have confirmed your age we won’t usually need to check again. (Exceptions can occur, for example if you change your name).

(You can help us check your age by ensuring your name and address are spelt absolutely correctly in the order form :) )

How your data is used

We use as little data as possible. The only data that ECigaretteDirect keep is information needed to send your order, and your date of birth (so we only have to check once!)

Your age is checked using Experian, which will check the information you provide against information in existing records to confirm you are over 18. No credit check is performed but a record of the search will be visible to you on your credit report. This will not affect your ability to get credit.

Why do we check age?

As you may know, there has been some concern that under-18’s may try vaping.

This is against both our company policy and the law.

And as responsible retailers, we need to do everything we can to ensure that every customer is of legal age.

For more information, see our Terms and Conditions.

How Secure is e-Cigarette Direct?

Your privacy is important to us, and your personal information should remain just that - personal.

See the little green lock in the search bar? That’s our security certificate (SSL or secure socket layer to be precise). It encrypts all the information you enter so that no-one else can see it.

Information you provide for age verification is sent securely to Experian and no details of the checks are stored in our system. Ever.

If you have any concerns, please call our friendly customer services team on 01792 852843 (Mon - Fri, 9am - 5pm).

For the techies: Our SSL certificate uses an sha256 hashing algorithm.
