The bigger shops are using nitrogen for testing because the
sniffers are <br>
cheaper and it does work, but I have CO2 on hand for the
welder so why <br>
have a bunch of extra bottles to pay for.<br>
<br>
I've found a lot of leaks just using the cheap bubble fluid
you can get <br>
in the dollar stores. Doesn't have all the extra stuff like a
dish soap <br>
has and it creates larger bubbles.<br>
