1. Connect the pressure test pump: The pressure test pump is connected to the indoor water supply pipeline system from the lower pipe outlet of the indoor water supply pipeline through the connecting hose.
2. Fill water into the pipeline: Open the main water valve to fill the indoor water supply pipe system, and turn on the pressure test pump pressure relief switch at the same time. After the pipeline is filled with water and the water tank of the pressure test pump is filled with water, the total water entering the household is closed immediately. valve and test pump pressure relief switch.
3. Pressurize the pipeline: Press the handle of the pressure test pump to pressurize the indoor water supply pipe system, and stop the pressurization when the pressure gauge of the pressure test pump indicates that the pressure reaches the test pressure (0.6MPa).
4. Discharge the air from the pipeline: slowly loosen the plugs of each water outlet, and tighten the plugs immediately when you hear the air is discharged or water is sprayed out.
5. Continue to pressurize the pipeline: Operate the handle of the pressure test pump again to pressurize the indoor water supply pipe system, and stop the pressurization when the pressure gauge of the pressure test pump indicates that the pressure reaches the test pressure (0.6MPa). Then complete the pressure test of the indoor water supply pipe system according to the specified inspection method. After the test is completed, turn on the pressure test pump pressure relief switch to release the pressure in the pipeline.
