Not a pleasant surprise, there may be a sudden lack of water in your well.
Very often it happens like this:
It seems that a well was drilled quite recently, the drilling foremen promised that it would work for twenty years, and it once became empty. Most often, not suddenly, at first the water flowed cloudy, then generally dirty, with a large admixture of clay, began to flow more and more slowly, and then completely disappeared. This happened due to the fact that, most likely, the well silted up, since it was initially doomed - the drilling masters who drilled it simply either cheated, or simply did not want to, or could not do it correctly - in two columns.
Almost any wells, if they are not made on sand, whether they are not deep twenty meters 
wells, either deep over a hundred meters, should be drilled in two or even three columns. This is done in order to cut off the upper layers of unstable soil, since various quicksand, loams and silty mud, flowing down the outer walls of the borehole casing pipe, settle at the bottom of the well, clog the sump and the entire well, so sometimes even the pump cannot be pulled out.
In order to somehow save and reanimate an aquifer, it is necessary to clean it, the so-called gelling of the well, which is able to restore the debit of the well.
However, let's be honest, if the water well is very young and only works a couple of three 
years, and subject to regular use, it still silted up, then most likely gelling will not help for a very long time, for a maximum of a couple of months. Since cleaning the well by the gelling method does not eliminate the cause of well silting, but only eliminates the consequences that will be repeated again and again. This means that you will have to desire a well again and again, and this pleasure is not cheap.
Especially the alarm should be sounded when the well silted up and stopped producing water very quickly - already in the first year of operation. This should not be, if this happened, then the work on drilling a well for water was done very carelessly, such a well is not viable, it will only cause trouble and disappointment in the future. If this happens, you have the right to demand the return of the paid drilling company Money paid for drilling a well for water, or require drilling a new well for water, but already with full compliance with the technology of all the nuances and subtleties.
The second reason for the loss of water is the aquifer has dried up.
After drilling the well, the water seemed to be the same, even though it did not flow as fast as we would like, but the drilling masters assured that you would use the well regularly, pump it through - there will be more water. But that didn't happen. You seemed to do everything as you were advised, but the water flowed less and less, and after a couple of months it completely disappeared, barely giving a dozen buckets. This can happen for several reasons, here are some of them: - a shallow well was drilled less than 15-20 meters into the so-called perched water - a layer of technical, not suitable for drinking water, formed and consisting of melt, rain and groundwater, into which all the dirt from the surface of the earth gets (from roads, fields, cesspools, and other sewers). In the spring, after the snow melts, and during the doge period, this aquifer is saturated with water, but with the onset of heat, it dries up, most often this happens by the end of summer.
- initially, a well was drilled for water in a low-saturated aquifer, although deep. The depth and water saturation of the aquifer depends on the geological conditions of the area. However, if the aquifer is chosen correctly, then even in a low-water-bearing horizon, a correctly made well will consistently provide the necessary water debit, without interruptions in supply. In order to increase the debit of a well for water, in a low-water horizon it must be drilled and cased with pipes large diameter 168-219 mm., or make a well design, to a greater depth with a large sump. However, not all drilling companies are able to drill water wells with such characteristics, and it is generally impossible to drill such a well with a mobile, portable installation. Our company has the most powerful and modern equipment capable of drilling wells for water in low-water and deep-lying aquifers.
The water in the well disappeared on the sand.
Sand wells are the most capricious, especially when they are also performed incorrectly. The sand does not contain a water-resistant layer of clay, the aquifer is eroded and does not have a specific area of occurrence, the sandy aquifer is unstable, its level is constantly jumping. Its water saturation is greatly influenced by weather conditions, seasons, and even the intensity of water intake from neighboring areas.
The most common sand drilling errors are:
- well casing with a string of very narrow diameter ( plastic pipe diameter 110 mm);
- the well is drilled to a very shallow depth (10-15 meters), at this depth the aquifer is very polluted groundwater and in hot weather it dries quickly, because. goes deeper;
- on the casing pipe, at the depth of the water intake, insufficient perforation was drilled (less than 3-4 meters), as a result of which less water from the sandy soil enters the well.
- at the water intake site, the perforation in the casing pipe was not well covered with a filter, or it was damaged during casing, as a result of which sand enters the well, silting it up and clogging the pump.
Very often, the reason for the lack of water in the well water supply is improper installation. pumping equipment and the entire water supply system. Therefore, first of all, it is necessary to trust the installation of pumping equipment and water supply systems exclusively to competent specialists. Our company provides a full range of services for drilling water wells and installing a turnkey water supply system, providing a guarantee for all work up to 1.5 years.
Each process can fail over time, and where automatic mechanisms are involved, even more so. Whole system autonomous water supply from the well should be regularly and thoroughly inspected for problems. Depending on the specific defect, a certain failure in the system is obtained. This article will discuss the case when water from the well comes in jerks.
Before you spend money on new equipment, you need to inspect all available parts for problems. For example, a malfunction of the pump elements is possible, in particular valve incontinence. It is also worth checking the supply voltage when the pump is turned on and during its operation directly on the contacts of the pressure switch, as well as the air pressure in the hydraulic accumulator empty without water (should be 10% pressure than the RD pressure). In the event of a hull defect pumping station to eliminate it, use the method " cold welding". Perhaps there is no pressure switch at all. The malfunction may be damage to the diaphragm (membrane) inside the tank.
If the pump is in good condition, then air is leaking into the system. All communications between the well (well) and the pump should be checked for leaks. Special attention it is necessary to pay attention to the water level in the source and the correspondence of the pipe diameter to the suction height. The smaller the diameter, the lower the height should be, that is, for example, a pipe diameter of 25 mm corresponds to a suction height of about 9 meters.
If all equipment is working smoothly and has no defects, the reason may lie in the well itself. In this case, the decrease in the amount and pressure of water occurs, as a rule, due to a decrease in well productivity.
"Silting" of the well means an increase in the amount of sand, silt and clay in the well. This is a natural process that increases when the water supply is not used for a certain time. Various deposits block the filter part of the well, the working part of the filter decreases and, as a result, its decrease occurs. bandwidth. The productivity of the well is also reduced.
Problem solving - well cleaning. Our company, which is engaged in drilling wells for water in St. Petersburg and the Leningrad Region, will help you with this.
How will this solution help? It will free the filter zone from various natural deposits in the water. The well filter is also cleaned, on which growths in the form of bacteria form. It should be noted that the cleaning of the well is carried out mechanically, without the use of chemicals. Sometimes there are situations in which cleaning the well is ineffective and it is not possible to get rid of the sand, since the filter has mechanical damage. In this case, you need to do overhaul wells, for which it is worth contacting specialists.
It is worth noting that it is advisable to seek help from the relevant companies immediately so as not to aggravate the situation and not bring more harm to the water supply system at home.
When building a water supply system country house an important role is played by the choice of water source, equipment, pipe material, etc. But no less important is who you entrust the installation to. The stability of your water supply system, its service life, as well as the amount of troubleshooting costs will depend on the above factors.
Any complex engineering system may require repair. The water supply system is no exception. The most important thing in this case is to quickly find the cause of the system failure and eliminate it so as not to lose water for a long time.
More often owners of cottages, private houses, summer cottages equipped with an autonomous water supply system, face the following problems:
Water from the tap does not flow in a constant stream, but in jerks.
When several taps are open in the house and / or Appliances(washing machine and dishwasher), water stops flowing.
The water just doesn't flow from the faucet.
Eliminate the causes of problems with the water supply system
Consider ways to troubleshoot problems with autonomous systems water supply.
1. Water from the tap flows jerkily
The cause of this problem is most likely a malfunction membrane tank. Sometimes it is also called a hydraulic accumulator, a storage tank.
This equipment is designed to provide stable supply water into the pipeline from a water source under constant pressure.
The hydraulic tank has two sections separated by a rubber membrane. Water is pumped into one section by a pump, air is under pressure into the other. When water enters the tank, the air pressure increases and, having reached a certain point, the pressure switch will turn off the pump, the water supply will stop. When you open a faucet or water flows, for example, into dishwasher, water is pushed out of the first section under the action of air pressure. At this time, it drops, and at a certain minimum pressure value, the relay will turn on the pump, the tank will begin to fill with water.
A battery problem may be associated with a decrease in air pressure below the required value. To remedy the situation just enough air ordinary car pump. If this does not help, then the membrane may have torn. In this case, it is better to buy a new hydraulic tank.
2. Lack of water with intensive water consumption
This problem may occur when the equipment is not properly selected and installed, or for other reasons during the operation of the water source.
For a water supply system, the characteristics of the pump that will pump water from the well are very critical. If its productivity does not match (lower) than the productivity of the well, then the pump just won't keep up pump water as much as you can consume. And it is very important to mount it correctly. It is not enough just to lower it into the water, you need to understand how much the water level in the well pipe can change - the pump must be submerged below the possible minimum value water level.
To perform the selection and installation work correctly, you need to contact an organization that has considerable experience in this area.
If the pump is selected and installed in accordance with all the rules, and the problem of a lack of water with the simultaneous use of several water consumers still arose, then most likely the filter of the water treatment system or the pipes are clogged well pump. Service specialists will help you to solve such problems.
3. Lack of water
Most probable cause this problem is a malfunction in the well pump. This does not mean that the pump is out of order. You may need to change the fuse or check circuit breaker in the electrical box and turn it on. You can fix these problems yourself.
If the pump itself breaks down, then you can’t do without the help of a specialist. At a minimum, dismantling a pump from a well requires special equipment and certain skills. A pump failure can be caused by improper installation, so do not trust the construction of a water supply system to inexperienced organizations.
It is quite difficult to determine on your own the cause of unstable operation or failure of the water supply system of your home. If you are not sure what exactly caused the problem with the water supply, invite a specialist, because self repair water supply systems can lead to larger and more costly repairs.
If you are the owner of a private well, then your site is located on individual water supply and thus you are not dependent on anyone. But it is worth facing a problem called “the water in the well has disappeared”, and all the worries fall on your shoulders. Because it is you who single person, making a decision about its water intake source and identifying the reason why this happens.
What to do if the water in the well is jerky, if there is little or no water in the well, we will understand below.
Possible problems with the source
The most common problems that can arise with a well and the presence of water in it are:
- Reducing the water level in the well (partial, periodic or permanent);
- Drying out of the well (meaning the complete drying of the well or a situation where water can quickly run out);
- The supply of water to the water supply system is jerky.
It is important to remember that the occurrence of such problems can often be the result of improper drilling and arrangement of the source. Therefore, to perform the work, it is always necessary to invite experienced professionals.
If the water level in the well drops
You all year round use your well and have never noticed a lack of water in your house before? Faced with a situation where the water in the well quickly runs out or is it periodically not completely up to the bottom level? Why did it happen? Dealing with possible reasons and ways to fix the problem. The main prerequisite for this behavior of the source can be:
- Natural change in the conditions of geology at the location of your well. That is, there is a displacement of the bottom of the reservoir from which you draw water).
- Change in aquifers according to the season (most often in the summer the reservoir may decrease, in the cold season - increase).
- Defects made during the arrangement of the well or during its operation (here we mean an insufficiently deep well, lack of sealing of the rings, the appearance of cracks, an incorrectly selected filter, etc.).
- Silting filters(if the well has not been used for a long time).
Important: all of the above possible problems are taken into account if professionals are working on the well. When self-fulfillment work may be allowed design error for the arrangement of the flask.
The reasons for the change in the water level in the well can also be third-party factors, such as:
- Drilling in close proximity to your well;
- Connecting to the horizon from which you draw water, another user.
- In this case, you need to wait a period of 25-30 days, and if the water level in your well does not return to its usual state or the phenomenon repeats with periodic regularity, then you can raise the question of deepening the well. Especially if initially the depth of the well does not exceed even 10 m.
Important: deepening the well is necessary only after a thorough analysis and identification of the causes of the situation.
The decision to deepen the well will be relevant in such cases:
- If in total you are confused only by the level of water, and its quality completely suits you.
- If drilling a new well is not suitable for you due to lack of free space on the site.
- If not found horizontal offsets between the rings of the well and the flask itself is not curved.
If the water is completely gone
This phenomenon often happens if your well is no longer new and has been in operation for more than three years. Often, such a well, dug to the level of the perch, gives either a small amount of water over time, or the water in it runs out (dries up) completely. The reason is the work of the aquifer at two or more points or its drying up. In this case, you need to either make (drill) a new well (or rather artesian well), or deepen the old one to a depth of more than 10 meters. The decision is made on the basis of financial capabilities and the available area of the site.
The flow of water in jerks
If the water pressure in the water supply system from the well changes periodically, then this indicates a change in the pressure force in the communication (that is, the pressure has dropped). It is only necessary to calculate at which level of the structure pressure fluctuations occur: at the level of pumping equipment, when water enters the pipe, or exclusively at one point of water supply.
You need to figure it out by elimination. First, you should check all the points in the house by opening the water. If the water comes in jerks, and there is no good constant pressure at all points, then the problem is in the pipe leading to the house. In this case, air can enter the pipe along with water and a kind of airlock, which does not allow water to flow with a constant pressure.
And yet the most common causes, along which the water pressure in the system changes and it goes in jerks, can be as follows:
- Insufficiently good tightness of the entire water intake system. It is necessary to check the operation of communication in all its sections from the pump hydraulic tank to all pipes.
- Breaking check valve pump or other moving parts of pumping equipment.
- Debris entering the pump. In this case, when the unit is turned on, the pressure rises too quickly and the pump is switched off. After the pressure drops again, the pump turns on. In this case, the water flows in jerks. The pump needs cleaning and filter replacement.
- Insufficient amount of water in the well or incorrectly selected pump immersion depth.
- Pump hydraulic tank diaphragm rupture. In this case, the pump may also be contaminated with small particles of debris. The hydraulic tank needs to be replaced to continue the operation of the well and normalize the pressure in the system.
- Or it may happen that air has escaped from the hydraulic tank for natural reasons. In this case, it must be pumped up with a simple bicycle pump. After such a procedure, the pressure in the system returns to normal, and the water again flows with a normal constant pressure.
From all of the above, it is worth drawing conclusions that well construction should be carried out at the level of professionals. They will accurately calculate the debit of your aquifer, the productivity of the well and the duration of its work, as well as select the optimal equipment. And in order not to encounter similar problems when arranging a well on the upper aquifers, it is best to immediately drill an artesian well.
