I use taps from the Miller/Coors system and do not have a problem with it venting.
When I first received the TAD Adapter, I had trouble with leaking (my own fault). Once I solved it, all was well. First I will chill the TAD keg in my fridge, then apply between 10-15 psi (depending on the level of carbonation I want) for about two weeks. I'm more of a set and forget type of person, and I'm also afraid what it will do if I apply too much pressure. This doesn't save a ton of time over priming with sugar, so I don't do it that often. I don't know if this is needed, but I will turn down/off my regulator before my first pour, then set it and leave it at 7 psi. I am curious to what others do.
I hope this helps and I hope it's clear. Can others comment if they've applied more pressure or tried shaking the TAD keg to see if that improves the speed of carbonation? I'm also curious to hear others experience with force carbing a TAD keg.
