I have bought a secondhand mobile set up for home . When I connect the keg ( fosters ) , it just pulls pints of froth . Then I find the following day the co2 is all used up . The system has a cooler ( think it’s classed as a flash cooler ) . I have so many questions and not to sure where to start . Also , the keg is in the shed , so not that cold . Should I put it in a fridge and drill a hole in the through the door .
Any help really appreciated
