There are many factors that operate the water pump in the best way, and among these factors: the presence of the brand, the appropriate use, the correct configuration, and the use of the device in an appropriate and correct manner, and despite that, a problem may occur with the pump and this problem needs a solution.

We will show you the main reasons why the pumps do not work, especially in centrifugal pumps, which are the most common types of pumps, and how to solve these problems as well.

What you should do when you find the water pump does not work and the reasons for this

One of the common reasons why a centrifugal pump has operating problems is lack of maintenance and improper use of the pump.

The main reasons for a malfunction in the water pump 

There are many reasons for the pump to malfunction. We will show you what happens in order for the pump to stop working. The first reason is noise, vibration, high temperature, and leakage. These are the main problems of the pump malfunction, and here we show you the important information on how to repair these pumps.

Also among these reasons:

Radioactive pollution:

Pollution is the most common reason for the failure of the water pump, and sometimes this pollution occurs due to handling the pump with unclean hands, and the liquid that is pumped may also carry pollutants.

lack of lubrication:

In order for us to be able to use the pump perfectly, oil and grease must be added to the bearings, and the addition of oils to the gaskets and seals occurs through the flow of fluids, and adherence to these orders works to maintain the pump.

 Incorrect use:

One of the problems that happen to the pump is the improper use of it, and the improper use of it leads to corrosion of the bearings, excessive pressure on the shafts, and vibration.

 4 ways to avoid problems that occur in water pumps

Now what is required is some oversight, because these malfunctions are often caused by ignorance or negligence, and we will show you how to avoid these problems that occur in your water pump.

The solution to avoid these problems is to take care of the installation, how to turn on, how to turn off and ensure normal operation, we will explain these factors to you in a precise way.

1. Start the pump properly

The failure of the pump often comes after a period of use, but it is very important to know how to operate the pump correctly so that it does not have a problem after its operation.

We will show you the steps by which to operate a centrifugal pump correctly:

• Fill the pump with liquid.
• The manufacturer’s manual should be seen, and the sealing valve should also be fully open.
• Open the closed sealing valves when the pump starts to operate
• You have to open it 10 seconds after the start of operation when the discharge valve is closed.
• You should now note the vacuum pressure gauge, and then you can know if the water is flowing correctly or incorrectly.
• If you hear a noise inside the box, you should turn off the pump and turn it on again, and this is normal because the box contains air.

Failure to operate the pumps properly is one of the most common cases of pump failure.

1. Restarting the pump again after leaving it for a while without work:

It is normal to find the pump not working after leaving it for a long period of time without running it, so you have to do something else to get it working again

• You have to make sure that the pump rotates in the right direction and find this direction on the cover plate and the rotation must be in the direction of the arrow.
•  The horizontal, vertical and angle alignment of the pumps must be in accordance with the manufacturer’s instructions, as well as with the hoses and the pump correctly.
• One complete cycle
• follow the order
• If the pump has been running for a period of time, you should turn it off to check the alignment and until you know if everything is fine or there is a problem.

If the water pump is left without operation for a long time, it will have problems if it is left without maintenance.

1. Ensure that the pump is filled

You must make sure that the pump does not contain air or any gases before filling the pump, because when there is air in the pump, damage will occur to the impeller, and there are many ways to fill the pumps correctly.

• You have to put the pump inside the liquid and hold it until air pressure and gravity also fill it up.
• It is necessary to leave a vacuum to tighten the air so that we can see when the system is full, which leads to raising the liquid to the casing.
• You have to put a valve at the bottom of the suction tube
• And pumps that cannot be manually maintained, there is an automatic filling according to the manufacturer’s standards.

Filling the pump correctly can achieve perfect use of the pump.

1.  To stop the pump correctly:

When you finish using the water pump, you must continue to focus while closing and opening the device.

• When the discharge valve is closed, the device will stop working.
• You must ensure that the oil is applied to the outside of the gaskets and sealant before shutting off the pump.
• It is important to make sure that the appliance is disconnected from the electrical source after it is switched off.
• If the pump is not in use for a long time, close the valve.
• You should drain the pump and maintain the connection input when you feel a freeze.

The irrigation hose and other parts of the pump must be properly separated when using.

These tips work to avoid the problems of domestic water pumps and will help you prevent making mistakes that prevent the water pump from working, meaning that you can, through these tips, avoid disruption of the pump, its heat, or other problems that result from misuse.

You must maintain the pump before use by taking care of it from the beginning, and you must know the appropriate time for its maintenance, and you must know that the pumps are used with water pressure or with polluted water as well.

When you use manual water pumps, you must maintain them every short period of time in order to keep them from rust and corrosion.

When you try to fix your water pump but you fail to find the problem, we will show you two important videos for you that will help you to fix the pump that does not work or that makes a sound and does not work.
