Crown tank leaking

[Debbiej]

dont understand why it started leaking. I've cleaned it, replaced o rings. Had it for 3 weeks no problem. The last two times it started leaking out of the air intakes . It did it again tonight, using the last bit of my favorite juice. Store closed tomorrow for Thanksgiving. Boo
Also noticed that the tank gets cloudy, the vape is getting in there. That can't be good. Any advice?
I'm using a Seigeli 150 and vaping at 80 watts using 80 VG. Again every time it leaks I clean and make sure o rings are in good shape. Thanks for any comment! I'm about ready to throw it away. Juice isn't THaT cheap

If you chain vape it, most particularly doing mtl hits, to the extent the tank is so hot you can't touch it, yes you might get a drop of liquid. Of are you using the RBA?

 

[Debbiej]

No not the rba, just coils .25. Within the past hour cleaned again and rechecked that top gasket. Didn't even hit it yet, picked it up and Eunice came pouring out of air holes.

Like lots of juice......... I'm not a mouth to lung hitter. Straight to lung

Have you replaced the coil. Sounds like it's running out the bottom. There is the Orrington at the top of the coil. In the tank. Seals the tank and coil. Have you replaced all the o-rings?

 

[Debbiej]

I haven't changed coil, will give it a try. Didn't wanna throw a good coil away. Lol but if it's lost me this much juice.......I looked and it appeared that the o rings on coil looked good too. I did notice it didn't screw in as well as one previous. Will try

You noticed what "didn't screw in as well as [the] one previous?"

It's kind of sounding like, in putting something (back) together, you may have got it cross-threaded? That could be tricky to correct, if so.

tested this? "You need to close the air holes on the afc before filling up the tank. After you have filled the tank up and put the top fill cap back on, turn it upside down and open up the air holes on the afc. This creates a vacuum seal and your tank should not leak at all." Seen on Fasttech forum.

I had the bottom gasket on the coil come off and got stuck in the threads..didn't know till I tried screwing in a new coil.. When it didn't want to seat I thought WTF and looked closely as part of the old coil gasket was stuck in the base.. I removed it with a pair of tweezers and my new coil screwed all the way down, seating on the base...vapes great and no leaks!

I'm sorry, but that's just voodoo. I know what the directions say, but closing the AFC doesn't change a single thing. It just gives Uwell a BS out and users a warm fuzzy they are doing it "right".

It's an open vessel. The AFC does not make it a closed one. I stopped closing it the first week I had it. Mine never leaks. The only time it does leak is when I fill it all he way into the little top braces. Then the juice has nowhere to go when you screw the top back on. Just have to bur it off real quick before it runs down to the base.

And turning it upside down isn't doing anything. Well, except turning it upside down.

I fill mine to just below the top. Never close the AFC, never have a problem with flooding.

I agree with Powerman. It's much more likely that the coil wasn't properly screwed in (there's a little tiny clear O ring on the coil that can move around).

 

[Powerman]

I have had a flooded base before. Can't tell you why. New coil. Didn't tighten it. Seal on top of coil moving around. Don't know. What I mean is that juice ran into the base, poured out of the AFC holes. I said WTF. Took it apart, nothing obvious, no more problem. And not closing the AFC isn't why juice drained into the base.

Overall, the Crown has been a very reliable leak free tank. Anything with liquid and o-rings will leak. For the most part, the Crown has been pretty trouble free.

The Crown is the only tank I've ever owned (and I've owned many) that doesn't consistently leak. I've never had an actual leak, worst case a little weeping mainly because I tend to overfill it - and I'm using a different drip tip that doesn't fit quite like the stock drip tip.

Powerman...... I'm with you. Never had it leak before, but now I have. After taking apart cleaning, putting in o rings, I finally changed the coil. Seems that was the culprit. Wanted to make sure so I waited a couple days.----No leaks! Thanx for all the advice. I like the crown tank, it's handy at work. BUT.......I love the taste of a RDA, plus I can make my own coils and wick. The Velocity is my favorite. Crown is second, looking into a RTA for it. Thanx everyone for the advice. What a great site

I also love the velocity mini, and the Crown is amazing. But I found the Crown RBA disappointing

 

[AmandaD]

That is so weird. I've had at least 15 and have never had any tank leak on me. (that wasn't my fault)
That includes both coils head tanks and RTA's.
Some get like a drop in the condensation chamber over time, but none do what I would refer to as leaking.

I can't really blame the tanks - it's my vaping style. I think I vape them to the extent they get really hot, then the metal expands, and voila - leaks! But the Crown doesn't do that (with the stock coils) which is partly why I'm so enamoured with it!

I got really tired of wiping off the leak spots on my tops

The problem with heat is differential expansion. If everything heats and grows at the same rate then heat itself is not much of a problem. Just a guess, but the most likely would be the joint between the atomizer and base. Specifically the atomizer deck. The shell is thin and would heat easily. The juice itself acts as a heat sink. The base is a bigger chunk of metal with more mass and would take longer to heat.

So I suppose it would be possible, but probably not that big of a deal. If anything it would be many cycles over the day and amount to long term seepage. But I can't see it being responsible for anything we would actually deem a "leak".

It's the only explanation I can think of. For instance, I have 4 subtank minis and one big one, and everyone of them spits juice onto my top once the level starts to go down. My billows V2 both leak,even my Crius leaks. It has to be me! And we're not talking seepage here, these are full fledged leaks!

 

[Powerman]

One thing about leaks... Metal doesn't seal. Nobody is going to machine a perfect sealing surface. So you need a gasket in some form. Regular rubber o-rings probably would not take our heat. Silicon can. There are some high temp silicone sealants. So we get silicone o-rings. They are marketed as sort of better quality, but really they are just better suited for our application.

But I'm more surprised how small they are. We don't need some big fat honking big ring, but they seem to small to me. You need a seat for a ring, or use a flat washer style. Then you need compression to compensate for any irregularities or even expansion from heat. It's not enough to just slap a ring in and call it good. Seems to me most are pretty minimal. Bottom line is the ring is the only thing sealing. If it's leaking, it's damaged, or not enough.

I would love to source my own rings. Not hard to do, but it hasn't been enough of a problem for me to look into. For you, you just need some calipers to measure inside/outside diameter and get some fatter ones. First place to go is tank to base. The coil/deck seal. The top and bottom of tanks seem fine. If juice is running into base it's the seal. If it isn't the seal, then the tank is simply running through the coil. So the cotton or wick or venting of tank isn't enough.
