1. | Connect the water outlet pipe to the water pipe under test (note: the connection is sealed). |
2. | Fill the pipe under test with water and exhaust the air, then turn off the switch. |
3. | Fill the water tank with fresh water, then shake the lever up and down to start pressure test. |
4. | If any slight water seepage is found during the pressure test, it should be inspected and repaired immediately, and the pressure cannot be increased under the condition of water seepage. |
5. | When the reading of the pressure gauge rises to the required pressure, you can stop pressurizing. |
6. | After stopping the pressurization, if the pressure shown on the pressure gauge does not decrease, it can prove that the pressure resistance of the pipeline is good. On the contrary, it proves that the tested pipeline has poor sealing performance and there is a leak causing the pressure to decrease. |
7. | After the pressure test is completed, loosen the water valve first to reduce the pressure to avoid damage to the pressure gauge. |
8. | When the pressure test pump is not in use, drain the water in the pump and suck in a small amount of oil to prevent corrosion. |
NOTE | 1. Before use, first tighten the switch clockwise. |
NOTE | 2. It should not be used in the workplace with acid and alkali and corrosive substances. |
NOTE | 3. The color of the actual items may slightly vary from the above images due to different computer screen, thanks for your understanding. |
