What you got for a pump?

I use a CMEPOL or TRS 21 for pressure testing up into the 350psi range (hydro test above 120 or so).

I insist they hold for at least a couple of days.

If you are building and testing our own, when I worked at an ASME fabricating shop, we hydrotested our products to certify them and fully flooded them and brought the pressure up using a Sprague hydrostatic pump, with no compress gases involved.

If we are operating a certified system that is at least 3X stronger than the pressure we are testing it to, and are just looking for leaks, we don’t have to hydrostatically test it, we can simply use air. If you doubt its capabilities, hydrostatically test it first and then with air so you can see the bubbles.

That doesn’t mean we stand in harms way when doing so. We tested our units in a plastic barrel full of water, but only went to 100 psi looking for leaks. We also stood beside it, with it tilted away from us, not over it.

As noted, compressed air rebounds like a big spring when released and at 100 psi is compressed air looking to occupy about 6.7 times more space. In pressure testing a sanitary assembly, the clamps are the weak link, so failures will launch the components vertically from a barrel.
