How to properly pump a well: methods for pumping after drilling and during operation. Well pumping is an effective and simple cleaning method. Is it necessary to pump the well?

An autonomous well solves all the problems of water supply for a private household. Drilling can be done by special companies or by the owners of the site themselves. But with installation casing pipe the work does not end; the next step is pumping the well after drilling. The long-awaited stream from its own source turns out to be dirty and cloudy, completely unsuitable for use. To make the water clear, you need to pump the well.

This activity must be carried out immediately after drilling. Sometimes the rocking procedure is postponed and construction begins, laying pipes and electrical mains. Such a delay in pumping water may result in the need to drill the well again - silting occurs, the speed of which depends on the composition of the soil. Therefore, already at the drilling stage it is necessary to collect necessary tool, study the pumping rules and, after gaining access to water, immediately begin the cleaning procedure.

Pumping out dirty water

Why is pumping done?

The process of water pollution in a well has natural causes. There are many particles dissolved in the aquifer, which, thanks to small size easily pass through the filter grid. Siltation of the bottom conceals the height and reduces the productivity of the source. Over time, sand and other particles will completely clog the well so that it can no longer be used.

Attention. Pumping a well after drilling cleans not only its bottom, but also the area located near the casing.

The length of time you wait for clear water depends on the depth of the source and the type of surrounding soil. Cleaning a shallow well for sand will take about 12 hours, while an artesian well will have to be pumped for several weeks. Autonomous source on clay soil very difficult to swing. Clay is difficult to wash out, so you will have to remove hundreds of cubic meters of water and spend a lot of time. The main thing is not to stop working, the water will definitely clear over time.

How does water change after pumping?

Bleeding pump

Before pumping a well, it is necessary to select equipment. In order for the unit to cope with its functions, it is important to take into account several criteria:

The unit for pumping out suspended sand and turbidity from the bottom must be powerful enough to lift a column of dirty water to the surface.
Submersible models are selected; a surface pump will not be able to cope with a water rise of 9-10 m.
Domestic and inexpensive mechanism. The equipment will only serve to clean the well, after which it will be unsuitable for use. It makes no sense to pay a significant amount for an imported unit, especially since Russian pumps are less sensitive to sand particles.

Advice. Do not forget to periodically pass clean water through the pump, otherwise it will burn out before the end of operation.

Theoretically, you can use 3 types of submersible pumps, which we will discuss below.

Vibrating

The model has the lowest cost, but does not have enough power for pumping, so it will quickly deteriorate.

Screw

The design has low sensitivity to contamination, so it pumps out sand well. Its disadvantage is big size and price.

Centrifugal

This best option in terms of cost, power and other qualities. The most common warrant for cleaning sources.

Bleeding with a vibration pump

Advice. If you purchased a productive and high-quality imported submersible pump, leave it for installation of the water supply system. He handles pressure very well clean water into the system.

Instructions for pumping

After purchasing an inexpensive centrifugal pump, you need to purchase a steel cable for immersion and holding. It is better not to use synthetic cords. The equipment will have to be raised and lowered several times, and it may get stuck in the mud and have to be pulled. A nylon cord cannot withstand such loads, but a steel cable can handle it. It is recommended to install a winch, then you will not have to manipulate the pump manually.

An important question that is decided before pumping a well is where to divert dirty water. The farther the dirty wastewater is from the source, the better. The submersible pump is not lowered into the pipe to the very bottom; it is suspended at a height of 80-100 cm. This distance will allow sand particles to be lifted and drawn in. The equipment will undergo a long working marathon from several hours to several weeks. Timely maintenance will help extend the life of the pump until the end of the process.

Placing the pump in the well

Advice. If clean water does not appear for a long time, experts recommend changing the pump model used. Instead of a centrifugal one, you can install a screw version.

Common mistakes made by newbies

When starting to pump a well on their own, source owners make various mistakes. Knowing about the common mistakes of predecessors, you can avoid in your work:

Significant distance of the pump from the bottom (more than 1 m). In this case, the equipment will pump water without practically capturing sand particles from the bottom of the well and the area near the walls. Poor cleansing will lead to rapid siltation.
Low hanging of the unit (closer than 70-80 cm). The pump, being in the thick of suspensions, will quickly become clogged with particles of sand, clay, limestone and other impurities. You will either have to frequently flush the pump (which is difficult to do because the equipment gets stuck in the sludge), or buy a second one until the end of pumping.
Close water drain. If the dirt removed from the well is drained nearby, it will return to the source, nullifying all efforts to pump it up.

Preventative work

Siltation also occurs during well operation. To keep the water clean, you need to take preventive measures. During seasonal operation of the source in winter period his work stops. The pump does not work for several months, the water stands still, and sand particles settle at the bottom. By spring, you may end up with an unsightly picture that requires washing out the bottom sediments with a hose clean water. When bottom sediments rise up the pipe, which means the erosion work is finished. To prevent the problem, you should run the pump for 2-3 hours a day, even if there is no need for water.

Ways to solve problems with a well

Pumping a well after drilling does not require special knowledge and experience; patience is important. In order for the source to provide clean water in sufficient quantities in the future and not silt up, it is necessary to properly pump the well.

Don't forget to rate the article.

The last meters were drilled, the well gave water. Can we consider the job done? It turns out - no! The last technological operation remains - pumping the well. If you neglect it, the case can safely be considered ruined.

This especially applies to shafts drilled using a mud-wash solution. Clay particles tightly clog the pores and cracks of the aquifer, preventing water from passing through to the filter system; it is necessary to remove clay inclusions and “pump” the well.

When pumping water from a new water intake, you need to pay attention to its condition - dirty, cloudy liquid is supplied from the well, unsuitable not only for domestic consumption, but also for irrigation.

There is only one conclusion - you need to flush the aquifer from drilling residues, which is why pumping is used. The process occurs with the continuous removal of water from the water intake, stimulating its intensive influx and leaching of drilling products. If you do not pump the well, all the turbidity will settle to the bottom and walls of the casing and completely paralyze the water intake.

Using a standard pump from a well kit for this process is impractical. There, expensive imported units with high productivity are usually used. And the pump for pumping, as a rule, is a centrifugal pump with a capacity of at least 3 m 3 / hour; most likely, it will fail during such operation or will require disassembly, washing and cleaning during the pumping process.

You will also need a long enough hose to divert the water away from the well. This will prevent it from flowing back into the well and the need for complex land reclamation if the pulp is drained on the site.

The procedure for performing work when flushing the water intake

When water appears in the well, it is necessary to interrupt drilling and establish the actual values of the static and dynamic levels, as well as, to a first approximation, the flow rate of the well. If its indicator is low, drill further, achieving complete opening of the formation. Further actions:

Lower the flushing pump into the well until it stops, then lift it above the bottom of the well to a height of 70 - 80 centimeters and begin pumping out water. To place the pump in the well, you need to use a thin cable with a large margin of safety. If the unit is skewed inside the pipe or the pump is sucked into a mass of silt or sand, it can be reliably removed. When using the cord supplied with the pump for this purpose, there are frequent cases of its loss in the well;
after 1.5 - 2.0 hours of continuous operation of the pump, you need to remove it from the well, disassemble the working chamber and thoroughly clean it and the impeller of dirt;
At the same time, it is advisable to install a bottom gravel filter, for which 30 to 50 kilograms of gravel in a mixture of medium and fine fractions are poured into the casing pipe; the casing column must be raised and lowered 5–7 times, allowing the filter mass to spill beyond the limits limited by the pipe;
lower the pump into the well, set it to the same level of immersion and further pumping can be continued;
control of the immersion depth of the pump is needed in order to most effectively remove polluting components from the well; if it is lowered lower, it will quickly become clogged with dirt, if higher, it simply will not remove it and it will precipitate.

When concluding an agreement with a contractor, you need to especially pay attention to the inclusion of a clause on the complete flushing of the water intake, otherwise the customer will be forced to independently decide how to pump the well after drilling with his own hands.

It is necessary to pump the well until clean water and gravel filter products appear in the drain. How long this will take depends on the nature of the soil and the drilling method.

Cleaning time for different wells

It’s already becoming clear how to flush a well, now let’s determine how much time it takes to get rid of silt and unnecessary sand:

for wells for upstream water and the second sandy horizon, it is necessary to flush for 6–12 hours, while acting correctly, you can obtain high-quality water intake with sufficient flow rate;
The most difficult process is cleaning the water intake in the gravel aquifer. The easy penetration of flushing solutions into the formation causes a wide area of contamination, so flushing is usually not possible quickly. To completely clean the water intake, water has to be pumped out for weeks, and the volume of dirty liquid sometimes reaches about 500 cubic meters. This is the reason for the high cost of such water intakes;
It’s a little easier to flush the water intake for limestone. Typically, the aquifer is a fractured structure of this material with many capillaries, so viscous clay is washed out of them extremely reluctantly, and the time spent is not much less than when cleaning gravel wells;
great success will be opening the water lens or achieving a clean water layer at artesian depths. In these cases, you can do the flushing with your own hands in a few hours if the source is properly opened.

Compressor pumping of a well

Any driller knows how to properly pump with compressed air. This method is used when there is no electricity at the work site. Mobile compressors with internal combustion engines are used, capable of supplying 2 cubic meters of air per hour to the water intake shaft.

Air is supplied to the bottom of the pit through a perforated metal tube with a muted end. Air rises through the well pipe, carrying particles of sludge with it and carrying them out.

If the casing diameter is more than 5 inches, it would be correct to use an airlift system. It consists of two tubes. Air flows along one of them, entering the mixer. The second sucks in the sludge and transfers it upward along with the air.

How long it will take to clean a water intake in this way depends on its depth and the height of the dynamic level.

The ease of application of the method determines the possibility of doing the washing yourself.

About the advantages of the compressor flushing method

The method is significantly more effective than any other - the rate of sludge removal is several times higher than using any pump. Consequently, the time required for such a process is minimal.
Removal of sludge containing large amounts of large solids. Since no mechanisms are used, the size of the inclusions does not matter, and there is no wear or breakdown of the equipment.
Well pumping can be carried out in the absence of electricity.
Applicability of the method for doing it yourself.

Disadvantages of the method

These include a sharp drop in efficiency with increasing hole depth due to increased air flow.

Application area

The method is ideal for flushing water intakes in fine sandy, fractured and clayey rocks at relatively high dynamic level wells.

Flushing is the most important technological stage water intake devices. Allows you to check the correct opening of the water carrier, ensure the operability of the well and achieve the production of water with high consumer properties. If you want to save money, it is quite possible to do it yourself. Good luck and clean water!

And the fact that they do not require a license. The flow rate of such a well is quite enough to all year round provide water Vacation home or a dacha. To ensure that the source provides clean water, well pumping after drilling. A well is an expensive structure, so it is important to pump it correctly. How to do this and also How long does it take to pump a well after drilling?, will be discussed in our article.

Why is pumping needed?

When drilling is just completed, the well gives muddy water, unsuitable for consumption either for food or for economic purposes. The fact is that the water in the underground horizons is saturated with small particles of clay, silt and sand, which easily pass through the gravel layer of the filter and settle at the bottom of the well. This is a constant process that gradually leads to silting of the well and a decrease in its flow rate. Leveling up helps to clean the water directly near the well from silt and dirt and make it suitable for use.

How to pump a well

If drilling is carried out by experienced specialists on a turnkey basis, the owner will receive clean water on his site without going into too much detail. technological process. If drilling is done with your own hands, or there is a desire to save money, then you need to understand how to pump a well from sand. At its core, pumping wells is simply pumping water out of it. The procedure is simple, but to successfully complete it you need to take into account a few tips.

1. Selecting a pump for pumping. For this purpose, you should not use powerful, expensive equipment purchased for permanent use in the well. An inexpensive submersible centrifugal pump is quite suitable, which you won’t mind using for pumping dirty water. During the process you will have to clean it more than once and, perhaps, throw it away after pumping, but it will do its job. And the new pump can be installed to operate in clean water.
2. How to install the pump correctly. For pumping, the pump is suspended less than a meter from the bottom of the well, at the level of the gravel layer. This position will allow the pump to effectively capture sludge and bring it to the surface. If the pump is mounted too high, it will not be able to capture fine sludge particles and will not function effectively. If the pump is installed too low, it will quickly become clogged with dirt and stop, or it may even get buried in the silt, so that it will be very difficult to pull it to the surface. For the same reason, it is important to hang the pump on a strong steel cable. This way, even if the pump gets stuck, it will be easier to pull it out.
3. How long does it take to pump water? It is impossible to answer this question immediately. The process can last from several days to several weeks. clay soils. This is due to the fact that the clay solution formed during drilling penetrates deep into the soil and is difficult to wash out. In any case, intensive flushing must be carried out until the well produces clean water.
4. Where to dispose of dirty water. It's unlikely you'll want to water muddy water plants or use it in some other way. Dirty water can be thrown into a ravine, onto a road, etc. The main thing is to stay away from the well, otherwise it will get there again and the whole process will be useless.

As you can see, even a non-specialist can handle pumping the well. The main thing is to stock up necessary equipment and patience, because as experience shows, after drilling, more than a dozen tons of dirty water can be pumped out of a well.

Solve the water supply problem for the owners country houses succeeds by drilling a well on your site. Often, such a choice is the only way to ensure home ownership of water for domestic and economic needs. It happens that a process that is costly in terms of labor, time and money is completed, but the water coming from the well is so dirty that it is impossible not only to drink and cook food, but even to use it for watering the garden.

The fact is that small particles of soil solution clog the outlet cavities of the aquifer. In order to ensure the flow of clean water into the mine, it is necessary to perform the final technological operation - pumping the well. Let's learn how to pump a well with your own hands.

You can pump a well in your own yard without disturbing the situation

Why do you have to pump a well?

In addition to fairly large solid fragments and sand, the aquifer contains tiny particles that freely pass through the filter elements installed in the system. Precipitating at the bottom and lower part of the well, they reduce its productivity, ultimately reducing the flow rate to zero.

To prevent this phenomenon, it is necessary to rock the well. The purpose of this manipulation is to remove the smallest fragments from the water mirror located near the intake pipe.

In other words, it is necessary to pump the well after drilling.

Basic rules for rocking after drilling

To properly pump a well, you should follow several recommendations. High-quality flushing after drilling allows you to remove contamination not only from the inner surface of the casing, but also a fine suspension of clay from the water surface in which it is immersed. As a result, the cleanest water will flow from the kitchen faucet, but to achieve this result you will have to work hard. The basic rules for performing rocking after drilling are as follows:

right choice pumping equipment;
proper organization of the work process;
determining the time required to complete it.

Obviously you can't drink this kind of water.

There is no need to purchase an expensive pump specifically for pumping. An inexpensive submersible modification of this equipment is suitable, since in the process of pumping a suspension of silt and clay, its working parts will be subject to significant operating loads. For proper organization During the production process, you need to know where to fix the pump and where to drain dirty water. The time it takes to complete the work directly depends on the composition of the soil and its geological structure.

Selection of equipment and organization of drainage area

When choosing pumping equipment, it must be taken into account that large volumes of contaminated liquid will pass through it. As a result, it is necessary to purchase inexpensive domestically produced units, which can simply be sacrificed if necessary.

The pump will need to be periodically removed from the shaft for cleaning. To perform this manipulation you need to stock up on flexible metal cable or a strong cord, otherwise the work will be complicated by removing the pump that has fallen there from the depths of the barrel. During operation, the surface of the cable or cord is checked for abrasions.

According to experts, vibration-type pumps can have a harmful effect on the shaft and walls of the shaft, shaking them, so centrifugal models of this equipment should be used. It is necessary to provide high-quality insulation electric cable nutrition and the ability to increase its length if necessary.

Putting the above circumstances together, you can determine which pump is recommended to pump the well after drilling. Useful information about the selection of equipment can be found in articles and

A pump for pumping is needed more reliable and simpler

In the process of pumping a well, the volume of contaminated water removed can exceed several tons, so it is necessary to properly organize the drainage site. It must be located as far as possible from the well, otherwise dirty water will return to the well and will have to be removed again and so on ad infinitum.

The contaminated liquid can be poured into a tank of suitable volume in which it will settle, after which it can be used for technical needs.

Do-it-yourself well cleaning technology

Cleaning the well yourself is quite possible. The technology for pumping up a well after drilling is not particularly difficult. Flushing a well after drilling is performed as follows:

pumping equipment is placed in the mine shaft so that the inlet pipe is located above the bottom;
the equipment is started and the process of pumping out contaminated water begins;
after some time, the pump is removed from the well and cleaned of contaminants;
then it is placed back into the mine and work continues;
These procedures are repeated until absolutely clean water steadily comes out of the pipe.

The inlet pipe of the pumping equipment should not be located too close or too far from the bottom surface. If located close, a very intense flow of silt and sand will quickly damage the equipment, moreover, it can be sucked into silt deposits, and it will be very difficult to remove the pump.

Layout submersible pump for pumping a well

If the inlet pipe is too far from the bottom surface, it will not capture the bulk of the contaminants, and the well flushing will be of poor quality. In practice, the immersion depth of the pump is determined as follows. Lower it until it touches the bottom and then raise it approximately forty centimeters. If the outgoing stream is too contaminated, another ten or twenty centimeters of cable are selected.

Cleaning time depends on well parameters

A reasonable question arises: how long does it take to pump a well yourself? The time to clean a well depends on such parameters as its depth and diameter, the power of pumping equipment, as well as on the composition and geological structure of the soil. It is very difficult to clean a well from clay. Cleaning a fifty-meter-deep mine shaft takes about 48 hours. In the case when the depth into the ground is twenty meters, the amount of work in time is much less: shallowly buried wells are much easier to pump.

A special place should be provided for pumped water

It is most difficult to remove fine clay contaminants; the more of them there are in the soil, the longer the time it will take to pump the well. Sometimes it can be measured in months. The more powerful the pumping equipment, the greater the volume of liquid it can pump per unit time, that is, the time to clean the well is directly dependent on this parameter. Minimum time pumping is twelve hours, you can understand that the process is over by the steady flow of crystal clear water at the outlet of the pumping equipment.

What to do if the build-up is prolonged

If the build-up has dragged on for too long, you need to analyze the production process for the presence of the most common errors in its organization. These include incorrect placement of the pump above the bottom surface and incorrect location of the dirty water drainage point. If the suction pipe is positioned too high, the bottom layers are simply not cleaned; if it is too low, the internal parts of the structure quickly become clogged with dirt, and the efficiency of the pump decreases sharply, until it completely fails.

This water is currently only suitable for irrigation.

Dirty water will penetrate back into the well, contaminating it again, if the drainage point of the pumped liquid is close to it. It needs to be equipped as far as possible; it would not be amiss to build a clay castle. Consistently eliminating these errors will help improve correct work. If these actions do not lead to success, you need to seek help from specialists.

Methods to combat siltation and quicksand

Flushing the well after drilling is not enough to ensure good quality water during the entire period of use of the source. Over time, the bottom and walls of the mine become covered with silt deposits, and this situation is common. At the same time, cleaning a well with low flow rate from silt and sand increases its filling capacity.

During the period of snow melting, soil water moves, along with which sand layers called quicksand move. They can clog the outlets of the aquifer. Signs of siltation of a well and the formation of quicksand in it are a decrease in its flow rate and the appearance of water supplied from it. musty smell. Mineral deposits give it a brown color. To prevent such phenomena, the following methods are used:

increasing the intensity of operation of pumping equipment, especially if no one lives in the house during the winter;
washing out contaminants with high-pressure water jets;
carrying out well pumping.

Clean water is the result of proper well pumping

The most popular hydraulic flushing method. A hose is lowered into the well, through which, using a pressure pump, high pressure fluid flow is supplied. It destroys contaminants and washes them out. The process continues until clean water with filtration backfill elements comes out.

Also applies mechanical method cleaning using the so-called bailer. The special shape of a heavy metal product allows you to destroy contaminants when thrown into the shaft and scoop them out when lifting to the surface. It is necessary to clean the well at the end of winter and rinse it for preventive purposes.

Dear reader! Your comments, suggestions or feedback will serve as a reward to the author of the material. Thank you for your attention!

The following video has been carefully selected and will certainly help you understand what is presented.

The well must be pumped immediately after drilling, this must be done according to the instructions, and until the water is clean. Also, pumping wells is important during operation, as it silts up over time. In order for the aquifer structure to work correctly, it needs to be monitored and pumped in a timely manner!

Why do you need to pump a well?

Well pumping is the most important stage of the organization autonomous water supply, which cannot be ignored. IN groundwater contains a lot of contaminants, impurities and insoluble inclusions, which is why it is prohibited for use for drinking or other household needs. To eliminate the problem and effectively clean the liquid, you will need a comprehensive well pumping.

In most cases, heavy mud is present only after drilling activities are completed. But the problem may arise in the future.

Small clay particles or larger inclusions collect in the lower part of the trunk, which leads to siltation. The problem is aggravated when the well is rarely used. So, if the water was not used during the cold season, when spring returns, a lot of sediment may appear, which will create problems.

How to pump a well after drilling

To figure out how to pump a well after drilling on your own, you need to study step by step guide and familiarize yourself with each stage of the procedure. If it is performed by a team of professionals, and not by amateurs with budget equipment, the pumping service should be included in the contract.

In other cases, you will have to solve the problem yourself.

Preparing for work

Any pumping of a well begins with preparatory stage. First of all, water is pumped out using a pump. Modern installations can pump out 3-6 m3 of untreated liquid per hour of operation. This increases the final cost of the project, but is an indispensable action.

The exact time it will take to pump depends on a lot of factors. On average, events take from 12 hours to 2 days. Sometimes beginners have to pump out dirty liquid for a couple of weeks or even months. Among the key conditions that determine the duration of pumping are:

Well depth.
Specifics of soil layers and pollution.
Professionalism of the performers.
Operating principle and performance characteristics of pumps.

If the depth of the well is relatively shallow and the water is contained in limestone or sand, the problem can be solved in 1 working day. And when processing heavily contaminated fluid from an artesian well, it often takes up to several weeks or even months.

If the work is delayed, do not despair and stop the process. Only in rare cases do experts conclude that a well is unsuitable for operation.

The biggest nuisance is the increased content of clay deposits in the water. There were situations when water was completely pumped out of the well along with the clay. However, once the previous level was restored, the user was provided with clean and safe water with a pleasant taste.

Any well is a complex structure with a lot of individual properties. Even if on neighboring plot pumping took a couple of hours, there is no guarantee that it will take the same amount of time on yours.

Wells with lime deposits are considered problematic.

Possible delays in pumping may be due to damage to the pumping equipment.

Selection of equipment and preparation of the drainage site

Before starting work, it is necessary to determine which pump to pump the well after drilling. You should also take care of a place to dump the pumped out liquid.

To treat dirty compounds, you cannot use simple pumping units, which are intended to supply water to the room. Not all models are able to cope with large volumes, sand deposits and other suspended particles.

To eliminate possible malfunctions in the operation of the pumps, it is better to buy powerful equipment with an extended service life in advance. Homework can be carried out using domestic systems "", "Rodnichok", "". Another problem is solved well by submersible.

It is not recommended to use for treating water with high content sand device with a snail-shaped metal impeller. This design is subject to rapid clogging and requires frequent replacement of consumables. Often the system fails after the first use.

Experts also advise against vibration equipment in favor centrifugal devices. There is evidence that vibration negatively affects the well, destroying column connections and rocking the casing.

If the drilling service is performed by specialists with professional equipment, be sure to ask them for a passport for the well and recommendations for pumping.

When preparing the pump, make sure it has a long enough cable. You should also prepare a cord for hanging the pump.

Since the equipment will often have to be removed from the well, the cord must be as strong as possible. Otherwise, it will break and damage expensive devices. During the procedure, its condition should be regularly assessed to determine abrasions.

When figuring out how to properly pump a well, it is necessary to provide a place for liquid drainage, because its volume can exceed a couple of tons. Dirty compounds are poured as far as possible from the well, otherwise they will need to be pumped out again and again. If dirt gets into the well, it will not only make the water unfit for drinking, but will also lead to cracking of the walls due to increased pressure.

Some of the liquid can be used for economic needs, such as watering. Before this, the water must be cleaned of all impurities, for which a primitive sand trap is created. A barrel with 2 holes is used as the main container - in the upper part and in the middle. Contaminated water is added to the sand trap at the top, settles, and then moves to the second hole. From time to time the device is cleared of precipitation.

Well pumping

To understand how to pump a well on clay, follow these instructions:

The pump is immersed in such a way that it is placed 30-40 or 50-70 cm from the bottom of the well.
The device turns on and water is pumped out.
After some time, the unit is taken out and washed in clean water. After this, it is placed back into the well, continuing the pumping process.
The action is carried out until a steady stream of clean water appears.

At the end of drilling, the well must be pumped to remove any remaining soil from it. When the flow rate decreases, the well needs to be pumped. The “Malysh” pump is perfect for the pumping process. Rocking up surface pump. Water drainage during pumping process. Container for pumped water The initial color of the water when pumping the well. The end result is clean water from the well.

If the pump is damaged, you will have to purchase a new one. During intensive flushing, the bottom of the structure may sink. In some conditions, the pump is fixed at a height of 50-70 cm from the bottom.

If the device is fixed higher or lower than required, the processing result will be negative. When excessive high mount the degree of purification will decrease, because debris will not be able to get into the pump. In the second case, the flow of contaminants will become as intense as possible, which is why the system will quickly begin to clog and may fail. The device may also get sucked into mud or sand, making it difficult to free it.

To improve cleaning efficiency, the pump should not be left static during operation. Experts advise moving it in a vertical plane by 4-6 cm with smooth movements. Any sudden movements should be avoided, otherwise the equipment may be damaged.

To select the correct pump fixation depth, do not rely on the length of the cord. After each successive flushing stage, the pump sinks lower.

If fluid does not flow, the system must be turned off. This is often explained by the fact that the pump was sucked into the sludge, or it burned out. To determine the problem, it must be removed from the mine and inspected. If normal operation has been restored, further flushing can begin.

If the pump fails, you will need to purchase a new device. It is better to purchase 2 units at once, so as not to waste time if 1 is damaged.

What to do if pumping takes too long

Some wells require multi-stage pumping, which takes a couple of months. If the work continues, but the result is not visible, you should familiarize yourself with the main mistakes that beginners often make:

The pump is located at a high altitude, which is why the bottom layers are not cleaned.
The unit is located low and becomes clogged with silt deposits.
Dirty water is directed back into the mine, causing the structure to become constantly polluted.

By assessing the points listed, you can find and fix the problem before complications arise. If the pumping work was very delayed, it is better to use the services of experts.

Causes of siltation and how to eliminate it

To know how to properly pump dirty water, it is important not only to purchase suitable pump to pump up a well with a low flow rate, but also to study the causes of pollution. If the liquid is constantly filled with sand, as a preventative measure you can use the idle method or run the pump for a couple of hours and pump out the liquid.

When figuring out how to properly pump a well, you should take into account the recommendations of specialists, which are suitable for most cases.

So, someone pumps the well with their own hands using a fire hose. This technology allows large volumes of water to be supplied inside and break up major contaminants or partially wash them out to facilitate further cleaning. The method is quite interesting, but is only suitable for those structures that have been in use for a long time, but for some reason require re-processing.

You can understand how to pump a well from clay right on site after completing the drilling procedures. For example, in addition to pumping the well with a compressor, you can use the technology of manual processing with a bailer. She is a heavy metal object, which sinks to the bottom of the structure to break up dirt and sand. Then the bailer is taken out, released and thrown back.

The well is also pumped using a vibration pump and motor pumps from Caiman, Hitachi, and Honda. Such devices sell for a couple of thousand dollars, but are worth their cost high efficiency and reliability.

Knowing how to pump a well on clay or sand, you can safely revive a hydraulic structure and protect the residents of your home from drinking dirty, silty and unsafe liquid.

Conclusions and useful video on the topic

To become more familiar with the specifics of pumping, it is recommended to watch informational videos that describe in detail each stage of drilling or cleaning a well.

Complete purification of water from impurities can require a lot of time and effort. But if you approach such events wisely, the task can be implemented in a short time and with minimal costs.
