**Connect the water outlet pipe to the water pipe to be tested (Note: The connection is sealed).
**Fill the pipe to be tested with water and release the air, then turn off the switch.
**Fill the water tank with fresh water and then shake the lever up and down to start the pressure test.
**If a slight ingress of water is detected during the pressure test, it should be checked and repaired immediately, and the pressure cannot be increased under the condition of water penetration.
**If the display of the pressure gauge to the required pressure. If after the pressure is completed, the pressure shown on the pressure gauge does not decrease, this can prove that the pressure resistance of the pipeline is good. On the contrary, it proves that the pipeline tested has poor sealing performance and a leak is present, thereby decreasing the pressure.
** After completing the pressure test, loosen the water valve first to reduce the pressure to avoid damage to the pressure gauge.
**When the pressure test pump is not used, drain the water in the pump and suck a small amount of oil to avoid corrosion.
