This is my first time kegging so I hope i'm doing it right. I followed the directions and put the keg below 40deg @ 30psi and rocked it for 2 minutes. Then i let it sit for an hour and a half and tryed to see if the carbonation took. Well I was letting the pressure out through the release valve to get it to the recomended 5psi but when it goes below 10psi the seal on the keg lid starts letting out air and breaking the seal. What do i do.
