The trapped pump is one of the most common and at the same time most unpleasant problems with drilled wells. Many owners automatically think that they need to pull the pump out of the well as much as possible, but this often aggravates the situation. In reality, there are many cases when the opposite solution leads to results: instead of forcing the pump upwards, you need to carefully move it downwards.
During well cameraing, professionals regularly encounter situations where inappropriate attempts end up causing even greater damage. However, the problem could often be avoided if timely and professional intervention were performed.
Why is one stuck? pump?
There are several reasons why pumps can get stuck. One of the most common problems is siltation and sand buildup at the bottom of the well. Over time, the sediment can surround the pump, effectively „siting” in the well.
Another common cause is a deformed or damaged well pipe. In older wells, the pipe wall may become deformed, cracked, or partially collapsed. In this case, the pump simply gets stuck in the narrowed section.
Problems can be caused by limescale, rust or even an improperly secured electrical cable. Sometimes the cable can get twisted or trapped between the pipe wall and the pump, completely blocking movement.
Another typical case is when the pump is lowered too deep and it is placed directly into the sludge zone. In this case, sediment gradually accumulates around the device, which eventually blocks it completely.
What do the owners do wrong in this situation?
Most of the damage is usually caused not by the original fault itself, but by panicked attempts. Many owners try to pull the pump out with great force, either with the help of several people or with mechanical assistance.
This can be extremely dangerous.
During forced pulling, the support rope may break, the electric cable may be damaged or even the pump itself may be torn off. well At this point, rescue becomes a much more difficult and costly task.
Many people try to "hook" the well into the well using various homemade tools, which can cause further damage to the pipe wall. It is not uncommon for the well to partially collapse as a result of poor attempts.
The biggest mistake, however, is trying to apply force without knowing the exact cause. In the case of a stuck pump, the first thing to do is to determine what is preventing movement.
When you didn't have to pull it out, but push it in
In a real-life case, the owner of a family home contacted the experts saying that the submersible pump was completely stuck in the well. Several people had previously tried to pull it out, but to no avail.
However, during the well camera inspection, it turned out that the pump was not stuck, but was squeezed by the sand and mud that had accumulated underneath it. The pulling only strained the structure even more.
The solution was to carefully move the pump down a few centimeters to loosen the buildup around it. It was then possible to remove it without damage.
This clearly shows how important an accurate diagnosis is. The problem is often not what it seems at first.
How does it help? well cameraing?
Well cameraing is now one of the most important diagnostic methods for examining drilled wells. With the help of a special waterproof camera, specialists can see exactly the internal condition of the well, the position of the pump and any possible obstacles.
During the camera inspection, you can quickly find out:
- is there any deformation in the well pipe,
- Is there any sediment or sand around the pump?,
- Is the pipe wall damaged?,
- Did any section collapse?,
- Is the cable or suspension twisted?.
The biggest advantage of well cameraing is that it makes the problem visible without any disassembly or guesswork. This not only saves time, but also significantly reduces the chance of further damage.
When can it still be saved? research?
Many people fear that a stuck pump automatically means the end of the well, but fortunately this is not always the case. In most cases, the well can still be saved, especially if a professional inspection is carried out in a timely manner.
There is a good chance of recovery if:
- the well pipe did not collapse seriously,
- the pump has not completely broken down,
- no serious structural damage,
- the problem is caused by sand or deposits.
In such cases, the system can often be restored to working order with special tools, cleaning, or compressors.
However, the longer they try to force the problem home, the greater the chance that the well will become permanently unusable.
What to do if the pump is stuck?
The most important rule: don't force it.
If the submersible pump gets stuck or jammed, it is worth contacting a specialist as soon as possible, who can use a well camera to accurately identify the cause of the problem. In many cases, a quick and professional diagnosis can save both the well and the pump.
With the help of modern well testing technologies, it is now possible to accurately determine what is happening below the surface, thus avoiding unnecessary demolitions and costly errors.
