BTW we pressurize our water systems with air to check for leaks before we allow water to move through them. We pressurize them at around 130psi

Sorry for the confusion

Pat,

I didn't think you were questioning their integrity, I just figured you were ignorant. Most people are about such things. Heck, I went to engineering school and they didn't talk about the Boiler Code much there either. I didn't learn much about it until I started studying for the License Exam.

BTW being ignorant about obscure technical subjects is not a reflection of your general mental abilities. It just means you haven't been exposed to that area of knowledge.

Of course if you are exposed and refuse to take into account what has been learned, then you move from Ignorance to Foolishness. The book of Proverbs in the Bible has a lot to say about fools, none of it good.

Depending on the application, testing piping with air may or may not be a good idea. In this case the pressure is reasonable and it is not for an extended period. Using an ultrasonic leak detector could also help find problems like small leaks before you make a big mess. The air is much more likely to leak through small holes than water and is much easier to clean up than water. But if a fitting was very poorly soldered, then it might also become a projectile.

It all depends on your prefered risk. In new construction for a house it might not be a great idea. But if you're retrofitting a building with lots of wiring and expensive electronics, like a recording studio or radar station then the risk might be worth it.
