We usually test the new boiler at 1 1/2 times the maximum working pressure (or the relief valve pressure). We will hydro-test using water, not air to 45 PSI on a 30 pound boiler, 22.5 PSI on a steam boiler. We always hydro-test after any major repair (Re-tubing for example). The boiler and relief valve are isolated from the rest of the system.
