I just tapped the first keg in about 3 mos tonight and have no pressure at all. I had my main tank turned off so there was no leak. The regulator seems to be working since I took it off and reset it and when I opened the tank both gauges went back to their right numbers. Inside the fridge I split the line with simple 2 line splitter. I have tried both in lines, replaced the IN poppet valve on the keg. The only thing I can figure is that something is keeping the CO2 from exiting the regulator even though the gauges work. There is a small inline shut off just after the reg but that is open also. Any suggestions???
