The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified test pressure. Pressure tightness can be tested by shutting off the supply valve and observing whether there is a pressure loss.
How long does a hydrostatic test take?
Duration of the test is two hours. Special consideration must also be given when multiple piping products are used."
What is the difference between leak test and pressure test?
The pressure test is usually performed at 1.1 to 1.5 times the design pressure of the system. The code leak test is applied to test the pressure boundary of the piping system and not the isolation points in the system, such as the seats or seal in valves.

How long do you pressure test water lines?
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.9 Mar 2016

What is the recommended test pressure?
The test pressure for service air and water piping should be 1½× the design pressure or 700 kPa (100 psi) for steel piping, whichever is higher.
