So lately, a few days ago to be exact I noticed a problem with my t3s tank connection to my vv ego battery. If I try to screw it on completely to make a flush fit. my battery will flash and not allow me to vape. Only when I unscrew it a little bit off the battery will than proceed to work. However this is becoming a hassle because it will sometimes dislodge from the battery all together. I did notice on the bottom of the t3s head, that the white o ring has a little bulge off the metal. Would this be the issue, and is their any fix to this problem or should I just buy a new head? Just looking for a fix because I been recently getting into rebuilding my wicks to save money. Any feedback is welcomed, thanks!
