T18e Coils - high percentage of faulty/leaky/floody ones...?

[GrimJim]

Hi,

Only been vaping about a month or so now, after buying an Endura T18e. When it works, the thing's great, but I've had many problems with coils gurgling/spitting/flooding, tank leaking....

Have googled extensively, have tried all suggestions, and am pretty sure I'm not making any schooolboy errors when filling tank/changing coil.

However it just seems like a fairly high percentage of coils are faulty - the ones that work give no problem, and seem to last around a week before starting to taste a burnt. But almost half the coils I've put in so far have flooded immediately, and continued to leak no matter what I try (shaking, blowing, q-tips etc etc). Only way to fix is to change coil again, and then - if it's a good one - no problems. I've found a lot of threads about these Innokin tanks leaking, but I'd say the device itself is fine - the problem is the quality-control on the coils!

I've also dissected a used coil to try and figure out exactly what's going on - and it strikes me that if the cotton isn't perfectly placed, the e-juice is just going to get straight thru the holes in the metal coil casing. This is presumably why some flood immediately?

Just to ward off the obvious replies, I'm not getting any juice in centre-hole, I have checked o-rings (and replaced, just to make sure), I am using appropriate e-juice, I'm not inhaling too fast, I'm not storing device on it's side, and the coils I'm using are verified genuine.

Anyway, because of this, I'm now looking to move to a different device - one that's more reliable, and has better quality control on it's coils!!

Does anyone have similar experience with T18e coils? Or anyone strongly disagree that almost half are faulty?? I'd love to find out this was a user error, as when it works it's great - but right now, it's just too unreliable due to the fact that every time I change a coil it seems to be a lottery as to whether or not the coil will immediately flood....

Are you priming your coils?
Usually you would prime a coil but I've heard that innokin advise NOT to prime the T18 coils and instead to just fill the tank, leave it for ten minutes and then start vaping.
I do it this way and don't have any problems. I also will give a good few pulls on it without firing it before starting to vape.
I did have one pack of five coils that were all crap. But I had bought them off ebay. They looked genuine and they didn't leak or gurgle but they would just start to taste burnt in like a day or 2.
Other than that I've always just bought them as singles from the vape shop and they've always been fine.

Correct. You do not prime these coils.
Just let them absorb for awhile.

the trick I found with T18 coils was to bath them ,, drop a few coils into a 60ml bottle of juice , or similar idea ..and leave the coils in there till you want to use em , fish em out with tweeters , wipe off the excess and fit in device . this gets the cotton soaked , expanded and bedded in .. get a few spits and pops at first but it would soon srttle down .

Many thanks for all the feedback and tips - sounds like I just have been unlucky with coils - and I'm not completely ruling out the possibility I did something stupid a few times while changing coils or filling! It's been fine the last week or so, last 2 coils not flooded, and if occasionally it's got a bit spitty/gurgly, shaking the excess out has worked. I'll see how the next box of coils goes!

I can see how this would help - and I'm wondering if I didn't jettison a few coils too quickly? e.g. the ones that I found flooded immediately on first filling, maybe if I'd taken the out and let them dry off a bit then re-installed, the cotton would have now expanded and might not flood on the 2nd filling? I mean it's still a bit of design or quality control flaw if they flood while following the instructions (i.e. install, fill with juice and leave for a while) but good to know that soaking them first can help with cotton expanding to fill any holes it might not originally cover.

I know this is an old thread, but found it googling as have the same issue.

Just started Vaping a month back. Not had a great experience with Innokin so far!

First kit that came, T20s couldnt charge as USB port didnt line up.

Second one leaked like a tap, even after changing coil and seals. And yes, it was lined up properly and and was using correct juice.

Also checked and both these genuine Innokins.

So, after sending that back to amazon went to a local store who reccomended the T18e instead, said they are still the best seller and never have any returns.

I'm now back on normal cigarettes because this too has started leaking all the juice out every time I top it up. Tried second coil in and doing the same.

Seems to be the coils in all cases as the juice is leaking from the battery connection on the coil itself.

Any suggestions of brands that are less leaky?

Welcome to the forum.

These tanks work on pressure. When you take a drag and pull air through the tank and coil, pressure is put into the tank. This pressure stops the tank from leaking via the airflow. These devices also draw their airflow via the 510 pin. If you look at the pin it has a hole. When you fill the tank you need to make sure you take half a dozen dry hits without firing the mod. Just take 6 good pulls without pressing the fire button. That should stop it from leaking. If you open the tank and release the pressure, fill it up and then leave it, you are pretty much guaranteed a leak via the 510 pin.

Since the initial problems I had with the T-18, I've found it to be very reliable. I know/remember how frustrating it can be to have people reassuring you it's a good product while you're experiencing problems with it, but I'd advise you to persevere! I've still got the same T-18 I had back when started this thread, very rarely does it give me any trouble. I'm still not sure exactly why I had the problems with flooding early on, but have had none since (except when changing altitude! e.g. driving in mountains). Maybe just bad batch of coils? I'd suggest you order some from a different site/shop just in case and try again. Still haven't touched or even really wanted a cig since getting the T-18 over a year ago! Worth finding a juice you really like too - many juices I've tried are horrible, but the find one you like and this helps vaping become a far more attractive option than smoking. Btw, have tried various other devices since, settled on an Innokin Zenith as 2nd device. I'd definitely recommend having more than one device, so you're never without if one does break/leak etc. And incidentally, my Zenith leaked early on too for some reason - but then has been fine since also!

My other tip, is change coils fairly regularly too - you can keep them going for ages, but will taste bad and not produce vapour at some point - if in doubt, change, they're cheaper than a pack of cigs after all. Especially if you're chain vaping (which you're likely doing while quitting cigs), they can go bad a lot sooner than most people seem to claim in my experience - never had a coil on any device stay good for longer than a week, usually less.

Anyway, try again is my advice, or get a Zenith!
