How to independently remove a pump from a well if the cable breaks or the device gets stuck in the casing. In both cases, you first need to correctly determine the cause, eliminate it, and only then raise the device to the surface. To ensure that the water pumping device does not remain in the well forever, it must be lifted correctly. Haste and unprofessional actions can damage the entire well, which will require serious repairs or the installation of a new water intake.
It may be necessary to remove the pump from the depths for repair or replacement. Also, pumping equipment must be dismantled before cleaning the well. If the device comes out of the pipe with difficulty or does not move at all, there may be several reasons:
- Overgrowing of the internal walls of the pipe lime deposits or silt sticking to them. The latter settles on the walls during prolonged downtime of the hydraulic structure.
- Foreign objects entering the water source that can get stuck between the device and the inner walls of the pipe, stopping the upward movement of the pump;
- Sagging electrical cable. Ideally, the electrical cable and the cable should have the same tension - for this, when lowered deeper, they are connected to each other using special clamps. If the cable is lowered without this fixation, it may sag and form a loop below the pump or wrap around it. It is these loops that will interfere with the free exit of the device from the well.
In the above situations, the integrity of the main safety rope is preserved. With its help, you will have to lift the pump, having first eliminated the cause of the jamming.
Pulling out a well pump using a cable
How to remove a pump from a well with a working cable
This situation can only arise in shallow sand wells. If the inside is overgrown with silt, which, when dried, turns into a solid substance, then it must first be soaked. To do this, water is poured into the pipe through the head in small portions (1-2 buckets), while the pump is swung to the sides using a cable. After a while, the softened sludge will drain from the side walls of the device to the bottom and the device can be pulled out. Soaking the sludge can take from several hours to a day, depending on the degree of overgrowing of the well.
When overgrown with limestone
This situation occurs in “limestone” wells, which themselves are very deep, plus limestone dissolves much worse than silt. You can remove the pump from the well yourself by acting on the deposits with special household products for descaling kettles, dishwashers or washing machines. Dry powder must be dissolved in the amount indicated on the pack. hot water and pour the solution into the well head. At the same time as pouring the solution, turn on the pump so that the water around it begins to bubble. If you pour in quite a lot of solution, and this will require 10-20 packs of descaling agent, then the limestone will begin to dissolve, and the device can be pulled to the surface without any problems. If the experiment is not successful the first time, it should be repeated several times every 5-6 hours.
Descaling agent
If foreign objects enter
How to get the pump out of the well in this case? Only by rocking the pump in the hope that a stone or other obstacle will slide down and stop preventing the pump from being pulled out. You can try lowering a separate long rigid cable into the well with a metal rod attached to the end. You need to try to push the obstacle down with this rod. To avoid foreign objects getting into the well neck, it must be securely closed.
When the electrical cable sag
If the cable sag, you must proceed according to the following algorithm:
- Using a safety rope, lower the device to the very bottom and very carefully try to align the loop. To do this, you need to swing the cable in different directions, while simultaneously pulling it up.
- Equalize the tension of the cable, cable and water hose. It is better to do this with an assistant who will pull all three elements away from the mouth.
- In the place farthest from the neck, fix three long components together. Fixation should be carried out in other places of their parallel location. Fasten the cable, cable and hose with clamps every 1-1.5 m.
- Pull out the pump and connect together those parts of the cable, cable and hose that were located in the depths.

How to get a broken pump out of a well
A broken cable is the most difficult case. If in the situations described above the device is pulled out using a cable, then if it breaks, you will have to pull the water supply hose or electrical cable. They are also attached to the device, but are not intended to require significant physical force. You can use this method if the pump in the well “moves” freely and is light in weight. If it is heavy, then it is better not to risk it, lower a strong rope with a metal hook tied to it into the pipe. Use this hook to hook the pump and pull it up. In this case, the hose and cable can be used as insurance if the hook comes loose.
Get it borehole pump You can do it yourself if you know exactly the cause of the jamming. Since the device is located at depth, it is almost impossible to carry out diagnostics yourself. Incorrect actions when lifting the device are also fraught with serious consequences. To prevent this from happening, you should turn to professionals - they have special video equipment for diagnostics. Having determined the cause of the stuck pump, specialists will remove it from the depths using professional tools.
Let's now try to figure out together how to pull the pump out of the well and whether it needs to be done at all in cases where it has stopped functioning. Perhaps the reason for stopping the water supply is not in it at all, but in the electrical cable or process automation system.
In order to understand this, you need to clearly understand the source device and connection diagram, which will now be discussed and, in addition, you can watch the thematic video in this article as additional material for clarification.
Construction and repair of the water supply system
Some possible reasons for stopping
Note. A borehole primarily differs from a water well in its small diameter and, in almost all cases, greater depth.
Drilling can be carried out “on sand”, or to the aquiferous artesian layer, which is much deeper.
- If your pump does not pump water from the well, this does not mean that it is out of order and needs to be replaced, so let’s take it in order. First of all, you should take into account the factor of what kind of well you have - “sand” or artesian, since in the first case the filtration layer may become heavily silted and the pump may not be able to cope with the thick liquid.
- One more possible reason If the pump in the well is not working, there may be problems in the terminal box at the head of the well, if the cable was connected through it (there could be a splice using a heat-shrink sleeve, but practically no problems arise there). In any case, the electrical cable will be short and will have to be extended, and the instructions suggest doing this through terminals like these, although this is not the best option.
- Before you pull the pump out of the well, you should also pay attention to the pressure switch, as the unit may not start due to the fact that the minimum starting limit is missing. There may be several reasons: settings failure, oxidation of contacts, or complete failure of the sensor. In addition, you need to determine whether voltage is supplied to the electrical cable at all (this can be done with an ampere-volt meter (tester)).
- Only after checking all these components and factors can the unit be pulled out of the well. Please note that this will have to be done together with the main pipe, so this work requires at least two people.
We take the pump out of the well
The question of how to hang a pump in a well is identical to the question of how to remove it, since both installation and dismantling are carried out according to the same scheme. The main fastener for the unit is a steel cable, one end of which is attached to the eye on the body, as shown in the photo above, and the other to the well head.
In the diagram you see the structural components of the well cap and, although its cover may not have a round, but an elongated shape (the cable entry may extend to the side), everything else remains the same. So, the steel cable is attached to the eye bolt and, in the same way as on the pump body, is clamped with special clamps (the clamp for the cable is made taking into account its diameter).
Note. In most cases, to steel cable The electrical cable is secured using clamps or ordinary copper or aluminum wire, so that you pull them out together.
Related articles:
We have figured out the cable and now we need to find out how the water intake is carried out - through a caisson (pit) or an adapter, since this will radically change the method of dismantling the unit from the well.
If the main line is routed through a caisson, then in 99% of cases it is polyethylene pipe 32 mm diameter. And the first thing you need to do is cut this hose in the pit, stepping back 15-20 cm from the casing.
After this, you need to insert the protruding pipe into the service pipe and only then lift the pump itself using a cable, pulling it up.
To do this, unscrew the cover, but do not remove the cable from the eye bolt - if it slips out when you lift it up with your own hands, it will still stay on this fastener, so you will not encounter force majeure circumstances.
But if the main pipe for water intake is connected via an adapter, then you cannot do without a rod with an external thread at one end. The fact is that the adapter consists of two parts, where one is tightly attached to the service pipe, and the other to the pipe that connects it to the submersible pump.
These two elements are connected to each other by a sled connection - the clutch is quite tight, especially since there is always a special waterproof lubricant.
On the top of the adapter part, which is attached to the pipe, there is a special hole with internal thread for fixing the rod. Therefore, you will have to find the right barbell ( metal pipe, A the required thread you can cut it yourself) and, lowering it into the well, screw it to this hole.
Once you get onto the threads and screw the rod, try to pull the whole thing up, just don't wobble it so you don't damage the threads or the adapter itself.
Most likely, the adapter will not disconnect the first time, since it is quite difficult to remove the pump from the well - the salts contained in the water clog the connection, and it needs to be moved from its place.
Therefore, you will have to make several strong upward movements to disconnect the adapter, and perhaps even use some kind of homemade winch or jack to do this.
Recommendation. If you cannot disconnect the adapter, then use two ordinary car jack.
To do this, you will need a crossbar with a clamp that will grip the barbell and two T-shaped supports under it.
Place jacks under these supports or instead of them and lift them gradually to avoid severe distortion - the adapter will definitely disconnect.Most likely, those who were involved in the installation knew which pump to install in the well and its diameter was several centimeters smaller than the cross-section of the pipe. Therefore, the lifting should occur without complications, except that in the first case the pipe will rub against the production pipe.
Conclusion
In conclusion, I would like to remind you once again that you do not rush to take out the submersible pump when it stops, but first make sure that the other components are working. Still, the price of such a unit is not a penny, and the labor costs associated with its dismantling are also considerable. Good luck!
From time to time, many homeowners have to deal with the problem of a pump stuck or falling to the bottom of the well. If you wish, you can remove the pump from the well, as well as remove it yourself. But you need to do everything in accordance with the instructions so as not to harm the equipment and the well. And before you figure out how to remove the pump, you need to know why it might get stuck or fall.
To avoid the pump getting stuck in the well, all work must be carried out extremely carefully.
Why can pumps get stuck in wells?
In order not to pull out the pump in the future, you need to immediately find out why it might get stuck or fall. In practice, this most often leads to the following:
To avoid the pump getting stuck in the well, it must be selected according to the diameter of the well.
- Incorrect selection of well pump. If the diameter of the purchased unit does not meet the manufacturer's requirements, it may get stuck. For example, if the pump has a diameter of 100 mm (4 inches), then it must be installed in a well with a diameter of at least 110 mm. If you don't follow this important requirement, during installation the pump may become skewed, and when lifted it will simply jam. This problem occurs especially often where the steady water level is located in the open trunk of the source. In such situations, the installation of a deep-well pump is carried out in an open hole. In such sources, due to the backwater of water, cracks widen and rocks break off. As a result, the pump may jam due to rock particles. Of course, you can pull out the pump, but you will have to spend time and money. Therefore, it is better to immediately select the appropriate equipment.
- The pump may get stuck due to errors during its installation. In particular, when the pump is lowered into the well, it is necessary to tie up the submersible cable in the pipe every 3-4 meters, a maximum of 5 m. Everything is done so that the cable is under slight tension. There is no need to tie a safety rope to the water-lifting pipe. If you do not do this, the pump will get stuck during lifting due to the submersible cable being tangled. In some situations, this type of problem occurs when using a rubber hose to act as a water riser. It is highly recommended not to omit deep well pump using a flexible rubber hose.
- The equipment may break or unwind from the pipe and hang on the cable. Most often this problem happens with powerful pumps, especially with domestically produced units such as ECV. Typically, installation of this type of equipment is carried out without the use of a safety rope. Instead, a steel water-lifting pipe is used. When the equipment starts up, a strong torque effect occurs. And due to the fact that there are no additional safety measures, the pump is twisted with the water-lifting pipe.
How to free a stuck pump?
The pump can be reached using homemade instrument consisting of a pipe and a curved spiral of fittings welded to it.
There are several methods to remove the pump from the well and return it to its normal position. A specific solution is selected taking into account what exactly led to the equipment getting stuck.
Thus, the pump may get stuck at the moment of lifting and stop moving upward even with great force. This is one of the most common problems. In this case, pulling the pump out of the well is quite simple. The reason, as a rule, is that the cable has sagged and is wrapped around the unit. To get rid of the problem, you need to carefully lower the equipment into the well, remove the slack in the cable and try to lift the unit. Make sure that there is no slack along the length of the cable, cable and hose. Preventing this is extremely simple. To do this, attach the cable to the hose using special clamps. In the future, if you need to lift the pump, these clamps will have to be removed and new ones installed instead, but it will definitely take you more time to pull the pump out of the well if it gets stuck.
Sometimes it happens that the pump that for a long time served without any complaints, it gets stuck so that it is impossible to get it out. Most often occurs in sand wells. The reason is their silting. The equipment is simply blocked by precipitation. In this case, the structure has to be “rocked”. To do this, you will need to carefully pull the cable up, and then also carefully lower it down until the unit is torn away from the sludge. The water will flow into the gap and gradually wash away the sediment, allowing you to carefully remove the pump. To avoid this annoying problem, clean your well annually.
To remove a stuck pump, you need to carefully swing it in different directions.
The pump can also get stuck in a limestone well if it is not maintained for a long time. The situation is almost the same as in the case described above. Wells on limestone do not silt, but the so-called. reverse siltation. This is caused by deepening the equipment too much. Because of this, the water surrounding it begins to stagnate. The water contains iron and potassium salts. When interacting with oxygen, they gradually turn into sediment. The latter is assembled at the end of the unit and pipes. Flushing the well in such a situation will not give any results, because... The sediment has a very high density. As in the previously described situation, the pump will need to be pumped carefully and slowly. The pump must be turned on. This way the water will get rid of the nozzle faster. In the future, pay more attention to source care and correct installation equipment.
When should you turn to professionals?
If the equipment is stuck in the middle of the source and there is a sound of impact, then the progress of the unit is hampered by damage to the pipe. It may appear due to the appearance of a dent, flattening of the edge, divergence of the joint, etc. In this case, you will need to give the equipment a rotational movement. Thanks to such manipulations, the pump can pass by the interfering place, but there are no guarantees. If you can’t do everything yourself, then in order to pull the pump out of the well, you will have to call specialists.
If the pump gets caught on a protrusion casing pipe, then it must be slowly lifted, while simultaneously rotating the hose around its axis so that it goes around the obstacle.
If the unit suddenly gets stuck, the reason may be that a stone, bolt, etc. was accidentally dropped into the source. The object falls into the space between the well wall and the pump, causing the equipment to jam. The most reasonable decision in this case, it is a call to professionals, because You most likely will not be able to fix the problem on your own.
If no effort to free the stuck pump produces positive results, try pushing the unit down. This can be done, for example, by means of connected steel couplings or other suitable devices. If the stuck pump is very close long distance, you will have to use a drilling rig with a fishing tool.
What to do if the pump falls?
It is quite difficult to lift the pump from the well, but if you really want to, you can do it. You will have to spend a certain amount of money and time, but the cost of developing a new well will definitely require much more significant investments. To lift the pump you will need the following:
- Steel wire. The length will have to be calculated individually. To do this, add 5 m to the depth of your well. As for the diameter, 3-4 mm will be enough.
- Tempered steel rod. 1 m is enough. The diameter should be about 0.5 cm.
- Welding machine.
- A crane-manipulator designed to lift weights weighing at least 100 kg and to a height of 7 m.
- Protective gloves.
In most cases, it is not possible to do without a crane for the reason that it is difficult for even two strong men to lift the pump from the well. The equipment is quite heavy, and it needs to be lifted continuously, which is very difficult. If you stop, the pump is almost 100% likely to fall off the hook. In addition to the crane, you will need one reliable assistant.
A hardened rod is used to create a grip. He bends into a hook. The ends need to be further sharpened. this work will require use welding machine. The finished hook is welded with steel wire. The second end of the wire is attached to the arrow of the crane.
The work itself is extremely simple.
You need to lower the hook into the well and, making screw and rotational movements, securely hook the hose or at least the pump wires. The method is suitable for sources of almost any depth.
If the pump is successfully engaged, it must be lifted and removed from the well using a crane.
Preparing for such work will take you a maximum of 1-1.5 hours. It may take several hours to lift the pump itself. It all depends on how successful your hooks are and how quickly you can hook the cable or hose of the unit. As for costs, the main component is the price of renting a lift. If you have the time and desire, you can make such a device yourself. This way you will reduce costs and save additional money. Good luck!
It may be necessary to remove a well pump submerged tens of meters various reasons. And during the ascent it often occurs unpleasant situation when the unit gets stuck or, even worse, falls down. What to do if the pump is stuck in the well and how to lift it in the easiest and most convenient way in a safe way? There are several reasons for such troubles, which will determine the choice of actions to remove equipment. Under no circumstances should you panic and use brute force: this may result in damage or loss of equipment (the cable may break and the unit may fall down), water intake equipment, and even complete loss of the well.
Borehole pumps are manufactured in such a way that their geometry matches as closely as possible the cylindrical shape of the casing pipe and its diameter. Average case diameter pumping equipment is 10-15 cm, and usually there is a small distance between the walls of the well and the unit - only 2-4 cm. Therefore, pumps can get stuck quite easily.
Fig.1 Modern borehole pumps
How to get the pump out of the well if it is stuck? It all depends on the reasons why the equipment remains inside despite efforts made to remove it. The most common factors that prevent the smooth removal of pumping equipment are:
- wrapping a broken or sagging cable around the equipment casing;
- siltation due to prolonged lack of maintenance;
- various damages casing pipe;
- objects falling between the walls of the unit body and the well.
Before pulling the pump out of the well, it is recommended to observe the situation while attempting to remove the equipment. Based on some indirect signs, it is possible to determine why the unit cannot be removed outside. If possible, a special video camera is used, which is immersed in the well and transmits the image to a PC monitor, allowing you to determine exactly why it is impossible to remove the unit.
Cable wrapping
When lifting stuck pumping equipment, the power cable is often in a free state without additional fixation, which is why it sags. When removing equipment, the broken wire is often wrapped around the housing, forming a loop, which makes lifting the unit up impossible. Main sign that a winding has occurred - complete immobility of the unit, which remains in place even with significant efforts when trying to lift it.
Fig. 2 A wrapped pump cable is one of the common causes of problems when extracting from a well There is no need to forcefully pull or pull the cable: it will break and the device may be lost forever. This problem can be solved simply: you need to lower the equipment back to its previous depth, loosen the cable to increase the diameter of the loop, and then carefully pull the pump up again. In most cases, the equipment is pulled out on the first or second try.
Siltation of the well
If the well has not been cleaned for a long time, then it is very likely that the pump has become stuck in a layer of silt, and it will be blocked by a thick layer of sand, clay or limestone, which can be up to several meters thick. To remove the pump in such a situation, you need to be patient.
The method of releasing equipment from under a thick layer of sediment takes time: it is necessary to slowly remove it, gently “swinging” and moving the cable up and down so that particles of sand or clay gradually sag along the edges of the case. As soon as the sediment is washed away with water, the pump can be easily removed. In the future, it is necessary to regularly clean the well to avoid re-sucking of the equipment into the sludge layer.
Damage to the casing wall
During long-term operation of a well, various damage often occurs. If during lifting the pump gets stuck in any area, and when you try to lift it you feel a mechanical obstacle and hear the sound of impacts, then the problem is damage to the pipe. A dent, chip, or discrepancy could form on its inner surface weld and other similar damage.
To safely remove the equipment, it must be rotated to allow it to clear the obstacle. However, in this case there is no guarantee that the pump will come out on its own. In some cases, the situation may turn out to be hopeless, and it will be necessary to drill a new well.
Hitting objects
If during the operation of a well some object falls into it - a bolt, a pebble - then this can firmly block the unit and, unfortunately, it is very difficult to cope with such a problem without the help of specialists. In most cases, you have to call a team with probing equipment. If you're lucky, specialists will offer the optimal solution, but most often you will have to sacrifice technology.
The pump came off and fell inside
If the cable holding the equipment breaks and the submersible pump falls into the well, then careless and unprofessional actions on the part of the well owners can lead to irreparable consequences. Therefore, it is better in this case to also call specialists armed with special equipment and a set of cables for extraction. Even if you believe in your strength, lifting broken pumping equipment from the bottom of a well or well will be technically difficult.
Fig.3 Crane for removing the pump from the well
Since the depth of wells is usually several tens of meters, lifting will require a specially shaped load, crane or one or two winches, a long thin cable, special gripping elements (cats), metal wire, canvas gloves. During the lifting process, it will be necessary to take care of protection against falling foreign objects.
All this requires a balanced and thoughtful approach, and optimal solution in 99% of cases there will be a call to specialists. Don’t risk the well, but trust to raise it fallen pump professionals!
Ecology of consumption. Lifehack: Submersible pumps used to supply water from wells drilled on site require periodic lifting...
Submersible pumps used to supply water from wells drilled on site require periodic lifting for preventative maintenance and minor repairs. Also, the rise of pumping equipment is also associated with the replacement of an outdated unit with a more powerful device.
However, the extraction operation is not always submersible pump from the well pipe passes successfully. It also happens that the pump gets stuck tightly in the pipe. Well owners who are faced with such a problem for the first time do not know how to remove the pump from the well without breaking the cable.
Reasons for pump jamming in the well body
Basically, all the reasons leading to the occurrence of this unpleasant problem are due to the human factor. When, during pump installation, the technological requirements for fastening elements of pumping equipment are violated, and due attention is not paid to their workmanship, it is difficult to expect a favorable outcome during pump dismantling.
1. Sagging electrical cable
For this reason it happens greatest number cases of equipment jamming. This happens by biting the slack electrical cable into a loop that is tightened around the pump body.
In this situation, you should not pull the device with all your might, as this will not lead to success. But what you pull on may break. Then it will be difficult to do anything on your own.
Experts who have lifted pumps from wells more than once advise in this case to try pushing the device back. Repeating the attempts, try to feel the slack and at this moment continue to slowly rise.
In general, “it is better to prevent a disease than to treat it.” In order to avoid encountering sagging electric cables in your practice, it is necessary to fasten it with special clamps to a pipe or hose at the installation stage of the system. Moreover, it is not recommended to attach an electric cable to the cable, since when it is tensioned, the clamps may fly off.
When lifting the pump, you must also ensure that the cable and hose exit simultaneously to the surface. There should be no slack in either the cable, the cable, or the hose.
2. Siltation of the well as a result of long-term downtime
There are often cases in practice when a long-term shutdown of a well leads to severe siltation. The resulting layer of sludge becomes an insurmountable obstacle to the pump. When a pump is stuck in a well for this reason, experts recommend starting to rock it, during which the device is either raised or lowered.
What does this lead to? Water may gradually begin to erode silt deposits. In the end, it is possible that the path up will become clear, allowing the pump to be removed outside. The main thing is not to rush things and do not be overly active in order to prevent the pump from jamming.
There are also non-standard way combating silted wells. It is necessary to involve firefighters in solving the problem, who, with the help of a hose lowered into the well, will be able to wash away the silt deposits. The released pump will move smoothly upward.
To prevent the process of silting of a well, it is necessary to carry out preventive cleaning, the frequency of which should be once every three years.
3. Solid obstacle - complex barrier
There may be a solid obstacle in the path of the pump movement, which will act as a wedge. Such a barrier could be:
- a dent in the pipe caused by soil movement;
- flattened edge of the pipe;
- burrs from a sloppy weld;
- a defect in the assembly of the sedimentary column, in which instead of threaded connection pipes, they are welded, allowing axial displacement.
Meeting such an obstacle is accompanied by a characteristic hard knock, while the downward movement of the pump occurs freely.
Is it possible and how to pull the pump out of the well in this situation? There are known cases when rotation of the pump with the help of a pipe around its axis helps to go around an obstacle that stands in the way. However, a 100% probability of freeing the movement of the device is not guaranteed. This could be a one-time success. But it’s worth a try, maybe in a specific situation the problem will be solved this way.
A tool, fastener part, or other foreign object that accidentally falls into the well can also become a solid obstacle. In this case, the pump stops abruptly and unexpectedly during ascent. This happens when a solid object gets into the gap between the well wall and the pump, which leads to jamming. In this case, the downward movement is free, and the upward jamming intervals change depending on the selection of the cable. The object will not be able to slip through, the gap is too narrow. Therefore, experts advise stopping and calling specialists. The special equipment they have is capable of removing the interference from the well.
4. Reverse siltation effect
This effect is observed in wells drilled in limestone soils. As a result of long-term operation, a sedimentary layer forms above the pump location, turning into a “plug”. To stop this process, clean the well every three years.
- A stuck pump in a well with a cable broken as a result of the applied efforts can be pulled out with a metal device with pins, popularly called a “cat”. Hooking the pump directly is considered a great success. Most likely, you can grab the end of a cable or hose while trying to pull the equipment up.
- To push down a stuck pump, some inventors manage to use a crowbar tied to a cable. The main thing is to tie the crowbar tightly so that when you throw it into the well, you don’t leave it there. Of course, this can be done if the old pump is no longer intended to be used, because the probability of its damage is very high. It may work at a shallow depth of the pump.
- Weld an “ear” to a meter-long section of pipe. After passing the cable, hose and cable through the pipe, lower the pipe on a separate cable into the well. Under the pressure of its weight, the pump can slide down and hang freely on the cable. Next, the pipe and pump are simultaneously pulled out of the well. Since the weight of the structure can reach 50 kg, the work must be carried out with an assistant.
- If the pump suspension has not yet been torn off when trying to forcefully remove the equipment from the well, you can fix it taut and periodically tap it. If any slack occurs in the cable, re-tension it and tap again. These actions can be carried out over several days. This is a method for those who are especially patient, but in some cases it is crowned with success.
What pushes people to invent in various ways solutions to the problem with a stuck pump? The answer is simple: the high cost of services from companies specializing in this area.In some cases, their cost reaches the cost of installing a new well. Therefore, in order to save your budget, you need to do everything possible in advance to prevent the pump from jamming.
1. Do not skimp on the quality of the cable used to suspend the submersible pump. It is advisable to purchase a cable and fastenings for it made of stainless steel.
2. Try not to use pieces of hoses and cables spliced together inside the well. After all, during lifting, these weak points can separate, the pieces can bend and jam the rising device.
3. It is advisable to buy pumps with a minimum diameter in order to increase the gap between the walls of the well and the equipment casing. It is clear that pumps with a small thickness are more expensive than their larger counterparts. However, if you compare the difference in the price of pumping equipment with the cost of a new well, then buying a thinner device becomes not so unprofitable. Replacing the pump in the well will reduce the likelihood of the device jamming again.
4. Install a factory-made head on the well that fits tightly to the walls of the well pipe. This part will prevent debris and various random objects from getting inside the well.
And do not forget to carry out preventive cleaning of the well. published
