Sep 18, 2025

Household water pumps are widely used in our daily lives, and some households install them due to their own needs. However, when the household water pump malfunctions, sometimes there is nothing we can do and we don't know how to repair it. Today, the editor will introduce common faults and maintenance methods of household water pumps, so that everyone can do it themselves in the future.

1. The household water pump has no response after being powered on.

Most of them are caused by short circuits in power plugs, power leads, and motor windings.

2. The household water pump is difficult to start or cannot start, accompanied by a buzzing sound.

During maintenance, a small bamboo blade can be used to quickly move the fan blades in the direction of operation. If the motor starts running quickly, it indicates that the starting capacitor or winding is damaged and should be replaced with a capacitor of the same capacity or repaired; If the motor malfunctions, it is mostly due to mechanical problems with the motor and pump head, such as bearing damage, impeller jamming, etc.

3. The motor can operate, but the speed is slow, and the casing is overheated and has a burning smell.

Most of them are caused by short circuits in the motor windings, and the motor should be disassembled. Depending on the damage, measures such as welding, jumper wires, isolation, and rewinding should be taken to repair it.

4. Household water pumps produce loud noise and vibration during operation.

Most of them are due to bearing damage or improper fit between the bearing and the casing, and the motor needs to be disassembled for inspection. If the bearing is damaged, it should be replaced; If the bearing deviates from the outer circle, the mating surface of the pump casing can be treated with chiseling; If the bearing runs inside the circle, chiseling can be used to treat the worn parts of the motor shaft. If the wear is severe, the method of welding first and then turning can be used for repair.

The above is the relevant content on common faults and maintenance methods of household water pumps. Please remember that once you encounter the above phenomena, you can troubleshoot according to the above methods without waiting for the arrival of maintenance workers. Of course, if you are not confident, you still need to wait for the help of the repairman to avoid causing greater damage to the pump.
