To find leaks, a low pressure (30-50 PSI) air test is just as effective as high pressure (150 PSI) water test. This is because the viscosity and surface tension of water is greater than that of air.

What pressure should you test pipework?
According to IRC, for supply system testing. You have to test using the maximum working pressure (80 psi) of water, or 50 psi of air. And you have to maintain the pressure for 15 minutes. For air testing drain-waste-vent (DWV) systems, you have to maintain 5 psi for 15 minutes.

If the pressure is 35-60psi, that is enough pressure and flow to allow most plumbing fixtures to work properly, unless there is a restriction within the system obstructing the flow from what it should be.
Is 60 psi too high for water pressure?
The pressure level can vary in most residential homes, but 60 PSI (pounds per square inch) is recommended. Water pressure should not be higher than 80 PSI. Anything higher can cause major appliances, including water heaters and toilets, to stop working properly because of the stress on plumbing and other parts.
