What are the common faults of cold and hot water self-priming pumps?

In our daily life, self-priming pumps for hot and cold water are very common, especially for high-rise residents. This kind of self-priming pump may be chosen for domestic water. In some hotels, apartments and dormitories, in order to increase the pressure of water, this kind of self-priming pump can also be used. How to use the self-priming pump, and what faults are prone to occur? Today, Bian Xiao will analyze it for you.

1. What are the common faults of cold and hot water self-priming pumps?

1, the most common fault is that its motor doesn't work. If this happens, don't worry. It may not be the motor, but the power cord is in poor contact or the plug is faulty. We need to check the wiring first, or change to a new socket. But if all this is handled, it still won't work. Maybe the motor is burnt out. There will be obvious symptoms, it will make a sound, it will not work, and it needs to be replaced with a new motor.

2. Self-priming pump is most likely to be clear in operation, but there is no water. Once this happens, it is likely that the inlet water level is relatively low, even exceeding its self-priming range, because the self-priming pump also has a certain water absorption range, which is generally controlled within 6 meters. Or because the seal is not done well, air will enter the pump body, but it will not come out.

3. The third is that it is easy to see that the faucet has been turned off, but the pump body is still running. This may be because there are sundries in the pump body. Especially on its switch, we can directly unplug the power supply and then clean up the sundries inside.

Second, how to use the cold and hot water self-priming pump correctly

1, before using the self-priming pump, be sure to check whether there are impurities in the pipeline, otherwise the pump will be damaged.

2. When using, be sure to pay attention to its water flow direction. Generally speaking, the outlet should be at the top, and its flow can be controlled by a check valve, which can control its opening and closing.

The above contents are about several fault analysis of self-priming pump. Generally speaking, as long as it is used correctly, this kind of fault problem will not occur.
