Test fluid should be deionized water, with quality level set by quality control engineer. In all cases, test must be donehydrostatically. Air test is not allowed2. Filling the system: Open all valves and vents to purge the system of air. Slowly inject the water into the system, making sure thatair does not become trapped in the system.3. Begin pressurizing the system in increments of 10psi. Bring the system up to 100psi and hold. Allow system to hold pressure fora minimum of two hours and up to a recommended 12 hours. Check pressure gauge after one hour. Due to natural creep effectson plastic piping the pressure will have decreased. If drop is less than 10% pump the pressure back up. At this time the system may be fully pressurized to desired test pressure.4. If after one hour the pressure has decreased more than 10%, test is considered a failure.
