I'm very frustrated and have no clue what to do. I finally got all my kegging equipment and set up my kegerator. I tested my keg for leaks using the dunk in bath tub technique and everything looked fine. After i siphoned my home brew i connected the gas line set the regulator at 25 psi to seal the lid and then dropped it down to 12 and let sit for a week to carbonate. Last night i was hoping to tap my first glass of kegged homebrew and nothing came out of the tap. I pulled the pressure release valve and opened up the keg to see if the beer was even carbonated and it wasn't. Should i be having this much trouble with this? Any tips or advice is much appreciated.
