Have you ever been troubled by the lack of water at home? Have you ever been irritable because your water pump failed to produce enough water? Have you ever been driven crazy by expensive repair bills? You no longer need to worry about all the above problems. The editor has sorted out the common problems encountered with household pumps to help you quickly catch the problems and repair the faults quickly.

The water pump does not produce water

Main reasons: 1. There is air in the water inlet pipe and pump body

Maintenance method: If the water inlet pipe leaks, you need to replace the pipe; check the tightness of each standard part of the water pump. If it is loose, tighten it with screws as soon as possible; if the sealing ring is severely worn, you need to replace the sealing ring.

Main reasons: 2. The water inlet length or height is too large (the water pump suction lift is too large)

Maintenance method: Find the "required cavitation margin" on the water pump nameplate. Simply put, it is the height difference between the water pump and the suction surface. If the distance is too high or too low, the suction lift of the water pump will increase. At this time, reinstall the water pump to the appropriate height.

Main reasons: 3. Channel blockage

Maintenance method: Listen to the sound of water flow when the water pump is running, whether it is weak or not at all; touch the temperature of the water inlet with your hand to see if there is any heat. If the above two phenomena occur, you can basically judge that the pipe is blocked. Re-clearing the water inlet pipe can solve the problem.

Noisy operation

Main reasons: 1. Unreasonable installation

Maintenance method: The water pump installation ground is loose and the slope is large, causing the water pump to vibrate abnormally, which will cause the water pump to make noise. This problem can be solved by adding shock-absorbing gaskets or adjusting the position of the water pump.

Main reasons: 2. Parts wear

Maintenance method: The aging and wear of bearings, mechanical seals, rotating shafts and other parts will cause the water pump to produce loud noises during operation. Only by replacing worn parts and performing regular maintenance can the service life of the water pump be extended.

Water pump speed is slow

Main reasons: 1. The water inlet valve is not opened

Maintenance method: If the water inlet valve is not opened or is not fully opened, the water pump speed will be slow and the water output will be reduced. Open the water inlet valve and the water pump speed will return to normal.

Main reasons: 2. Motor or impeller failure

Inspection method: After using the troubleshooting method to remove other causes such as voltage, wiring, water inlet valve, etc., if the water pump speed is still slow, it is most likely that the motor or impeller is faulty. In this case, you can only ask a professional maintenance technician to handle it. Do not Solve the problem yourself.
