Lavatube + Vivi Nova = Not working?

[SlimXero]

Ok so i've had a lavatube for some time (6+ weeks) and I've been using a 510-ego adapter to use my Kanger T2's on it, with no issues other than cheap adapter issues. I ordered a Vivi nova from mountolympus and originally had no issues. Switching around atomizers today, talking with a friend, and now my vivi nova will NOT fire on the stock 510 threading, but when i screw on my 510-ego adapter, it fires just fine.

My question is, has anyone else experienced this issue? What caused it and/or how did you resolve it? My lavatube has no warranty as it was on sale extremely cheap ($45 for the kit with charger, 2 batteries, LR 510 atty, drip tip).

start by testing your vivi on another device to make sure the head isnt bad

i've heard in lots of places they tighten down too far and cut off all air flow thus not working. loosen it up a bit, if that doesnt work buy a 510-510 adapter to extend it up a bit to allow airflow

 

[SlimXero]

well, like i said it works with the 510-ego adapter so i know the head is good, and when i draw i'm getting airflow. Thanks for the suggestions though.

Check the threading on your PV. If there's a substantial amount of juice on the threads, it'll prevent it from firing.

Also, what's the resistance on the head? If I'm not mistaken, if the resistance is lower than 1.8, the lt won't fire.

The center post in the LT is probably pushed down slightly. It makes contact with the adapter but not with the Tank by itself. GENTLY pry it up a little.

BTW adapters are commonly used to fix "center post contact" problems.

 

[SlimXero]

Thanks AttyPops, that's exactly whats going on. You're the man.

 

[SlimXero]

hmmm still having issues with this. It worked at first but now i'm back to the adapter. I went as far as popping the top cap off of the lavatube and pushing the center pin up with a small screwdriver and i'm still not getting anything.

 

[SlimXero]

Ok, I have finally narrowed down my particular issue. I don't know if it's from the combination of equipment i use or what, but i figured it out. If anyone else has this issue, now that i've figured it out, it's fairly easy to fix.

1. ) Take the head off the post
2. ) With tweezers or your finger nails, pull the center post on the HEAD out about 1/16 of an inch, so that about 1/32 of an inch is showing on each side of the little silicon grommet.
3. ) Screw back into place.

Tada! It's been working for me like this, and I've tried it with all 3 heads, it works now! WHEW. I was starting to very VERY angry.

Also, i was not fortunate enough to end up with one of the Vivi nova's that had that extra silicon cap inside the mouth piece, so mine pools liquid inside the top cap. Until yesterday. I had an epiphany and decided to try something. I took the silicon cap and metal "lid" off of the head, flipped the "lid" over and replaced the silicon cap. now the stem of the lid goes through the cap and into the mouth piece, making it much more difficult for liquid to travel up and virtually eliminating the liquid in the mouth piece. Picture:

So far, no liquid in the mouth piece, and very, VERY little liquid around the reservoir in the cap.

Alas, I'm still having connection issues. I'm going to go insane.

 

[Tramane Moulton]

I had the same problem I finally just put a drop of solder in the lavatube and now it makes great connection everytime

 

[SlimXero]

It's not the lavatube not making the connection. I've pushed the center pin up by taking the top cap off, and i've placed the atty head directly on the 510 connection on the lavatube and it works. It's the center pin on the vivi nova giving me a fit.

Common issue that I've seen. Most people just use an adapter or ego skirt and it solves the problem.

 

[AttyPops]

Huh. lol. They can't win. Originally, they had the center post too long and it hosed PV connectors. Since 2.5 it's close to flush (but should still protrude a bit).

So you pushed the center contact post down somehow?

 

[kiwivap]

Hi Slim,
I've heard of this happening before with some other pvs. The air holes for the vivi nova are down under the base of the vivi on the pin. In some pvs, when the vivi is screwed on, the air holes are blocked by the pv because they go down into the pv when screwed on.
That's why an adapter is working - its lifting the vivi up high enough for the air holes to work.

Raising the centre pin on your pv was a temporary fix, but the centre pin has probably moved back down a bit again. The best fix I know of is to keep using an adapter.

 

[JBR3AK]

Sounds like an internal electrical problem. I'd see if its under warranty and get it replaced. :/ sorry

 

[SlimXero]

The problem is electrical, it's not a venting issue. It's not that i'm not getting airflow, it is not firing at all. And now even with the adapter, it's hit and miss. I'm sure it has something to do with the center pin on the vivi, it seems to move freely. as far as i can tell, it has a single gasket close to the 510 connection and that's all that's holding it.

Lava tubes are nothing but junk especially the young june models.

 

[tc1]

Oh wow ... yeah, that center pin on the Nova shouldn't be moving around like that.

 

[AttyPops]

Epoxy (like JB Weld) is an insulator....

Of course, you'd have to make sure there's an air path (but maybe it's through the center anyway). So if the grommet is not holding the center tube in place, maybe you can gorp it up.

Of course, if you have to go buy the epoxy you're 1/3 to 1/2 way to a new V.N. And you'd have to find a way to rig the center post to stick out slightly while the epoxy dries.

I've not had center post problems with them yet (Knocks on wood)
