Tap water is usually caused by the following reasons: the water supply is cut off, the water pipe is blocked, and the pump is out of order. When there is no water in the faucet, the pumping power of the motor is not large, because there is no water for the motor, and the motor cannot generate enough power to pump water.
The water pump is driven by a motor to pump water. Its principle is to rely on the rotation of the motor to drive the impeller of the water pump to rotate, thus generating negative pressure, so that water is sucked out of the water source and then transported out through the pipeline. When the water supply is interrupted or the water pipe is blocked, the motor can't work normally, because there is no water, the motor can't form negative pressure and can't pump water.
When there is no water in the faucet, there are several solutions and countermeasures to be considered:
1. Check the water source: first, determine whether the water source is normally supplied. You can check the water meter or check with your neighbors to see if there is any water supply interruption.
2. Check the water pipe: If it is determined that the water supply is normal, it may be that the water pipe is blocked and there is no water flowing out. You can check whether the water pipe is leaking or blocked, and it needs to be cleaned or repaired in time.
3. Check the water pump: If the water source and water pipe are normal, it may be that the water pump is out of order. You can check whether the power supply of the water pump is normal and whether the water pump needs to be repaired or replaced.
It should be noted that the above solutions are general suggestions based on common situations, and the specific situation needs to be judged according to the actual situation. If you encounter complicated problems or unsolvable situations, it is recommended to seek professional help.
In short, when there is no water in the faucet, the pumping power of the motor is not large, because there is no water for the motor, so it cannot generate enough power to pump water. To solve the problem of water-free faucet, it is necessary to comprehensively consider and investigate water source, water pipe and water pump.
