Another "way to test for leaks is to mix some washing up liquid with water in an old detergent bottle, shake it up so the bottle is full of froth and squirt the froth onto the regulator, if there is any leaks it can clearly be seen bubbling through the froth"
Mod edit...This is done at your own risk and the poster or forum take no responsibility
