Water supply

The manufacture and maintenance of wells is a fairly crucial process. This design when creating requires compliance with certain standards, which subsequently should not only get the maximum efficiency of the product, but also greatly facilitate operation. This is especially related to the process where for maintenance you need to get a pump from a well.

Detailed study of the process

First you need to say that removing the pump is made during repair or cleaning of the well. That is why the design itself involves the creation of all the necessary conditions for this. Given this, in order to understand how to get the pump out of the well, the installation process itself should be considered, which will provide the answer to the question posed.

Installation

First of all, it is worth mentioning that the well is usually located in a specially created compartment underground. He is called a caisson. The purpose of this design is to protect the well from the environment and create a working space.
After the caisson is created, it should contain only a casing column, from which it will be necessary to perform all the necessary actions.
First, the pump is mounted to the pipe, which will be immersed in the well. It is worth noting that the installation manual involves the connection through a non-return valve to eliminate the appearance of water hammer. All connections of this type are usually threaded and fairly reliable.

The phased process of mounting the pump on the pipe with the fixation of the cable

After that, a metal cable is attached to the pump. It is best to use a product made of galvanized iron in a waterproof sheath. This will significantly increase reliability and quality.
The cable is fixed on the pipe, immersing it in the well. At the same time, the distance between attachment points should not exceed 1.5 meters. It must be said that the locking elements should not be clamped too tightly.
If all the work is done by hand, it must be remembered that the dive is not fully performed. First, lower the pipe until it stops and make a mark on it indicating the level. After that, lift one meter.

In the next step, you need the casing tip. Through it is a water pipe from the well. Also to it is fixed on a special clamp and cable, without creating a strong tension.
After that, the cap is installed on the casing, fixing it through the rubber seal with bolts.

Tip! In this case, described a typical way of installing the pump on the well, but it is considered one of the most reliable and correct. If you plan to manufacture a fundamentally different design, then you should worry about the safety of the pump in advance.

The main load when removing the device falls on the cable, which means that its choice must be approached very responsibly

Extract

Based on the installation of all elements, it is easy to understand how to get the stuck pump out of the well.
First of all, you need to remove the casing cap fastener, after disconnecting all water pipes from the system.
Next, gently start lifting. At the same time use only the pipe itself, without touching the cable. The fact is that otherwise it is possible to damage the joint, which is already subjected to strong influences and heavy loads.

If there are no serious damages, then the extraction should be fairly simple and not cause great difficulties. However, there are such situations when the pump breaks off from the water pipe and warps in the system.
In problem situations, you should first dive 20-30 cm.
Try to pull the design again.

Virtually all modern pump systems are designed in such a way as to prevent the occurrence of distortions with proper installation

If this fails, you need to scroll the pipe to try to get it, bypassing the clamps. This action should not cause difficulties if the fixation of the cable was not carried out too tightly.
As a result, only the cable and the pump remain in the casing string. It is worth noting that the price of such insurance is quite high, but if you save on the material, you can ruin the entire well.
Separately, it is worth noting the fact that the pump is fixed on the cable in such a way that when it is hovering it is positioned strictly vertically and without distortions. This allows you to freely remove it from the casing, since by plunging the pipe down first, we freed it from the vertical clamp, and by lifting it, we must completely align its stroke.

Tip! Do not attempt to pull the pump by the power cord. It does not have sufficient strength and can tear.

Only correct and high-quality initial installation can be the key to simple maintenance and repair, and excessive savings can lead to various kinds of difficulties.

Conclusion

After reviewing the video in this article, you can get more detailed information on how to remove the pump from the well. Also based on the text provided above, it should be concluded that this process will be greatly facilitated if the entire system has been correctly installed. That is why it must be approached very responsibly and with skill (see also the article Borehole pump connection diagram: several alternatives).
