6.5 Testing

  1. The system shall be tested in accordance with the manufacturers’ recommendations.

  2. Following is a general test procedure for GF Piping Systems. It applies to most applications. Certain applications may require additional consideration. For further questions regarding your application, please contact your local GF representative.

    1. All pressure tests should be conducted in accordance with the appropriate building, plumbing, mechanical and safety codes for the area where the piping is being installed.

    2. When testing plastic piping systems, all tests should be conducted hydrostatically and should not exceed the pressure rating of the lowest rated component in the piping system (often a valve). Test the system at 150% of the designed operational pressure. (i.e.: If the system is designed to operate at 80PSI, then the test will be conducted at 120PSI.)

    3. When hydrostatic pressure is introduced to the system, it should be done gradually through a low point in the piping system with care taken to eliminate any entrapped air by bleeding at high points within the system. This should be done in four stages, waiting ten minutes at each stage (adding ¼ the total desired pressure at each stage).

    4. Allow one hour for system to stabilize after reaching desired pressure. After the hour, in case of pressure drop, increase pressure back to desired amount and hold for 30 minutes. If pressure drops by more than 6%, check system for leaks.

    Note: If ambient temperature changes by more than 10


    F during the test, a retest may be necessary.
