Test plugs are designed for initial startup and testing, not continuous or frequent use
If continuous or frequent use is desired or expected, a test well should be installed for temperature applications and a needle valve installed for pressure applications
Tests should be made as quickly as possible because the inner plug resealing time is dependent upon the length of time the probe remains inserted, as well as the temperature and pressure of the system
The test plug may take longer to reseal at lower temperatures or pressure
The probe used for testing should never exceed a diameter of 0.156 in
The pressure gauge used for testing should always have a range of twice the system pressure
