went off on one ment 2 give u 2 kegging tips that might save u time n cash
1) always check the gas bottle mating face when u exchange a refill, soft brass and even tho caged in the neck can get a clout or 2 and get damaged, if gnarled at all it will probably seal ok on your reg but will chew up n kill the wsher so the next bottle u attatch could just drop out overnight,,, yep it happened..
2) flow control taps are great for low-med conditioned beers served upto 8psi (according to my gauges) over that pressure the sweetspot is impossible to hit nd needs a constant fix each pour never hitting it. at lower pressures tho they are great and can be set once and pour.
happy kegging
