First make sure you have the nylon/fibre washer installed between the
regulator and tank. The easiest way to check for leaks is with a soap
solution. Use a diluted solution of dishwashing soap in a spray bottle. Spray
all valves, regulators, connections and tubing and look for bubbles. The
compressed gas escaping to the atmosphere will cause the soap solution to
bubble. Some plastic tubing is incompatible with CO2. The gas will leech out
of small permeable holes in the tubing. You may want to consider silicon
tubing if this is your problem.
