Manual pump for water from a well: overview of models and the price at which you can buy a manual pump. Drilling wells in the country How to make water columns

Standpipe especially needed for use in populated areas where there is a lack of water coming from centralized water supply.

It is impossible to say that the device works perfectly, but it performs its functions perfectly, at least in the warm season.

The design of the water column is simple. It is installed in a well or on the ground and consists of:

valve;
ejector;
pipes for lifting water;
columns;
lever mounted to the column (these two elements are on the surface).

Disadvantages of standpipes

Despite the obvious need for use when the water supply is poor, this equipment also has disadvantages:

V water supply network should be enough high blood pressure, otherwise the performance of the column is noticeably reduced, in particular, when drawing water from a centralized network;
freezing of water in winter, especially at low pressure;
often soil and rainwater, if the corresponding valve, designed to limit the ingress of third-party liquid, is damaged or shifted (in some cases, water users who arrange it do not even know about it, but household water is already supplied with impurities).

The main functions assigned to the column: water intake and supply. Therefore, it is better to choose high-quality equipment for installing the column; moreover, this will increase the chances of maintaining the integrity of the gasket for collecting exclusively purified water from the water supply.

Water taps are used not only in populated areas, but also on construction sites and in suburban industrial establishments.

Basic requirements for a water standpipe

In order for the installation of the water dispenser to be correct and the device to work for a long time, the following requirements must be met:

it is better to install it near an intersection or near the sidewalk (however, it all depends on. If the installation takes place in a well, the location is determined; if not, it is recommended to do it as close to the sidewalk as possible);
installation of a water standpipe should be carried out on the basis that the service radius of the device should not be more than a thousand meters;
so that there are no problems with drainage, it is better to install it on a hill (but not at a significant height). The main thing is to maintain natural drainage;
It is not recommended to install on a dead-end line if it is carried out in the ground.

In general, standpipes are used over a wide temperature range: from -40 degrees to +40 degrees.

Installing a water standpipe yourself

Installation of the column must be carried out in the following sequence, as stated:

we connect a threaded pipe and a flange (you can take either welded or flat);
take a column into which a threaded pipe is carefully screwed;
we make sure that the flange does not exceed the size of the thinnest pipe that connects to it;
we install concrete pads that will form the basis for the standpipe. It is enough that their size slightly exceeds the dimensions of the future installation. It is recommended to take care in advance of providing the installation with concrete pads;
install sewer hatch, at the same time we provide high level stability and quick access to the device;
We wash the column with a specially prepared bleach solution (do not forget to take into account the proportions indicated on the package).

We considered the option of installing a water standpipe in a well. The device can be equipped with additional functional elements to expand the control and measurement capabilities.

Also, in order to protect the column from freezing, winter period can be insulated with any thermal insulation materials, covering the walls of the well with them.

This will be more reliable and stable. In the case of installation in the ground, this is not recommended, since it will not be possible to disassemble the heating material in the summer.

It is better to carry out installation at a depth of at least 75 centimeters and no more than 4 meters. What determines the installation depth?

From where the pipes are installed. The greater the installation depth, the greater the chance that the device will not freeze in winter.

The length of the pipe connecting the upper and underground parts can be different - it depends on the location of the device and, accordingly, the depth of the pipes.

This will allow the installation to be tightly fixed and not washed out with melt and rain water.

The installation schemes for a column in a well and in the ground are almost identical, but in the case of installation in a well, it is necessary to create two concrete pads, while one is suitable for a ground column.

As the heroine of the famous film said, whoever takes a pack of tickets will receive... Well, why not a water pump? , so that you don’t dig a well or drill a well? The problem can be easily solved.

At first water pipe d 25 mm, clamp it with a clamp and pull it to the beam, which has the shape of a half-beam. On one side of the pipe we screw in a metal tip shaped like a cone.
Together, and then, if possible, then four of us, using a wrench, we drive the pipe into the ground until it stops.
Using a coupling, we extend another pipe and forcefully (again with the help of a wagon) drive the pipe into the ground.
In the same way, we build up another pipe and continue to drive the entire pipeline into the ground until it reaches the aquifer.
In one stroke, the pipeline is clogged by 40-50 cm (if on clay).
During clogging, it is recommended to turn the pipeline clockwise and add water from above to facilitate clogging.
Then you will need to pull out the entire pipe string, unscrew the metal tip from the first pipe and instead screw in a perforated pipe section of 1-1.2 m and re-lower the entire pipeline into the already completed well.
Make and connect to the pipeline hand pump (water column). Its device is shown in the drawing.
It is possible to connect an electric suction pump.

Advantages of such a column: if all required material prepared in advance, the entire device can be installed in 5-6 hours. The design is simple, and the materials are quite affordable. In 5-6 presses of the handle, a bucket of water is filled.
Flaws: The depth of the aquifer should not exceed 10 m. It is impossible to break through the soil in rocky soils.
