hello everyone my first post on the forum.i,ve spent ages trolling the forums on this,my question is:atm my friend brews beer using beerkits and makes a fine job.this is dispensed from 2 king keg top tap barrels which have s30 valves fitted.to save hassle and time we are looking to use a standard pub style co2 cylinder for gas.the idea is to have a primary reg and 2 secondaries,1 to each barrel.are the king kegs suitable for this system?also i,m not sure how to connect to the barrel cap,plus what type of prv i should use.any advice on fittings and any help would be much appreciated cheers
