Don't take this as some kind of personal attack on your or anyone else, but I don't think anyone should run the Nuetech Tubliss system unless they do their own install and servicing of this system. I say that because if one doesn't know the nuances and pros/cons of this system by being fully capable of installing it, it can bring a fair amount of headache in some cases. Being intimate...sounds sexy...with the system helps in avoiding problems during installation, operation, and diagnosing potential problems.
I've been running the Tubliss system since '09. And even with finding nails, screws, wire, etc. in my rear tire while back in camp during off road trips, I've yet to have a flat while riding. When finding an object stuck in my tire, I've been able to remove the object, plug the hole with an old school string plug and continue my trip/ride until the tire was worn out. And, running sealant like Stan's, tubeless Slime, etc. is another requirement IMO to insure sealing punctures/leaks during a ride...or at least as much insurance as is possible. Like I said, I've yet to get a flat on a ride using the Tubliss system, and that's no BS. I even find it somewhat hard to believe...and I ride a lot.
OP, for an easy step, maybe get a quart of Stan's from a local bicycle shop or Amazon, install about 6oz., and see if that seals up wherever the leak is coming from. This can be a somewhat challenging system to install. No...it's not rocket science and does not require an engineering degree, but quite a few people badmouth the system because of user error during installation and/or operation. One may have success by having a shop or another party install the system on their bike, but I'm really convinced that it will serve anyone a lot better if they know how to install and service the system on their own.
