Storage tank for water in the country. Installing a cold water tank

Organization autonomous water supply on the suburban area provides an opportunity to enjoy the benefits of civilization, regardless of the presence of centralized communications. Most often, in personal baths, a cold water supply system is arranged from a well or a well, and a storage tank is used to provide water pressure. It is also required to collect a reserve supply of water in case of power outages. Where is the best place to place a storage tank for cold water so that the bath water supply system works properly and does not create problems for the owners.

Storage tank in autonomous water supply

Individual water supply system with storage tank arranged very simply. Water from a well or well is pumped by a pump, the type of which depends on the height of the water level in the source. Mostly in suburban farms, noiseless submersible pumps or stations with an ejector and its own hydraulic tank.

The pumping station is good if the suburban building has its own basement. Or there is enough space on the site for the construction of a change house for its placement, tk. this is quite a "sounding" equipment. But buying a station can save you from installing a storage tank if its built-in tank differs in volume sufficient for daily consumption.

Unattractive in terms of sound interference and surface pumps, but they are significantly cheaper. True, they pump water only from wells and wells with a high water table or from nearby lakes, ponds, rivers. For surface pumps, the main thing is that the height difference between the point of water intake from the source and the point of delivery to the storage tank does not exceed 6-7m, which is extremely rare in reality.

Due to the inclusion of a storage tank in the scheme, the water pumped out by the pump does not immediately enter the taps, the tank on the sauna stove, the boiler, the shower, the toilet bowl and other water points. First, water accumulates in the form of a reserve approximately equal to the volume of the reservoir. The water reserve in the storage tank makes it possible to use several plumbing fixtures at the same time. Without a supply of water, normal pressure for use would be in only one open tap, and that is not a fact.

In an autonomous water supply system, the cold water storage tank, in theory, performs the function of a water tower. The supply of water also allows you to reasonably limit the number of pump on / off, which is extremely beneficial for any technique. The storage tank is equipped with a mechanical, electronic or electric float valve to pump equipment didn't work for nothing because:

when the water pumped into the tank reaches the limit level, the float signals that the pump is turned off;
when the level drops, a command is given to turn on the pump to replenish the spent stock.

This eliminates unnecessary work of equipment and overflows. craftsmen Instead of a valve, they contrived to use a toilet bowl float mechanism, which corny closes the hole for water to enter when the required volume is exceeded. The pump can be turned on/off manually or automatically. You will also need a “dry running” relay to stop the pump if the storage tank is completely empty.

There are holes in the cold water storage tank that are required to connect the pipeline and to ensure the normal operation of the system as a whole, these are:

hole for connecting the supply pipe. Before entering the supply pipe, it is recommended to install a coarse mesh filter in order to mechanically prevent small animals and large grains of sand from entering the tank;
a hole for the overflow pipe, through which excess water is discharged from the tank into the sewer. They arrange an overflow a couple of cm below the float valve in case the latter does not work for some reason;
one or more openings for outgoing pipes supplying the water heater and cold water draw-off points. Often they are located in the lower third of the tank, but there must be at least 10 cm between the bottom of the drive and the output points, so that the inevitable for ground water sediment did not enter the line;
a ventilation hole in the cover of the drive, if the cover closes it from penetration into the container of dust, insects and other contaminants.

A hole for entering the supply pipe is sometimes arranged in the upper part of the tank opposite the place where the float valve is installed. However, in order to completely drain the water from the reservoir in order to preserve the autonomous water supply, it is recommended that the inlet pipe opening be located in the lower zone of the reservoir. It still needs to be equipped with a drain valve. If the lower location of the inlet of the supply pipe cannot be used for some technical reasons, then an additional drain hole will be required to preserve the water supply with a storage tank.

Methods for installing storage tanks

The type of water distribution and the set of equipment required for the trouble-free operation of the bath's cold water supply system depend on the location of the reserve tank. In low-rise construction, two main options for the construction of water pipelines with storage are used, these are:

top diagram , according to which the reserve tank is installed on the highest possible platform: on flat roof, a specially erected overpass, on brackets under the ceiling, a concrete podium inside or outside the building, an attic, etc. The installation height of the drive in top diagram– parameter adopted according to individual specifications. Accumulators of year-round water pipes are necessarily insulated if they were installed in an unheated room;
bottom diagram , according to which the reservoir for cold water is buried in the ground in the basement of the building or on the site, if water is supposed to be taken from the reservoir for irrigation and other household needs. For a year-round water supply device, the storage tank is buried below the freezing zone; for a summer water supply, it is enough to position the tank so that there is at least 0.5 m between its upper plane and the earth's surface. A lower entry of the incoming pipe should also be provided and a drain device should be installed on it.

Often, independent home craftsmen prefer the upper scheme. It is easier to build a water supply system with an upper storage tank with your own hands, and it will not require less expenses than an underground one. Water is distributed by gravity to the water points without additional devices stimulating its movement. The only disadvantage of the upper scheme is recognized as quite weak pressure, depending on the installation height of the storage tank. To create a pressure of 0.1 atmosphere, the tank will need to be raised by 1 m, for 0.5 atm. by 5 m. Do not forget that for the operation of a washing machine, for example, you need a water column pressure of 1 atm.

A water supply system with a lower storage location is sometimes referred to as a system with pneumatic capabilities. The pump pumps water into the underground tank, which compresses the air cushion there. When the water in the tank reaches a certain level, compressed air will begin to push it up to the water points. True, the pneumatic abilities of water pipes with lower wiring are rarely relied upon. They are too small. Most often, to supply water with a stable pressure from the lower storage tank, an additional submersible drainage-type pump installed directly into the tank with a float signaling device is used.

Optimum storage tank material

The volume of the storage tank should be equal to the one-time water consumption. In this aspect, everyone's preferences are different. Therefore, the acceptable capacity of the tanks ranges from 100 to 1000 liters. Requirements for storage tanks for cold water supply determine the upcoming operating conditions. In any case, the container must be airtight, wear-resistant, stable, and inert to chemical and biological contaminants.

As a storage device in the organization of autonomous water supply, you can use:

a home-made welded tank with or without a lid, if the quality of the water is not too worrying for the owners of the summer cottage;
factory opaque plastic container, instead of which it is quite acceptable to use eurocubes connected by pipes;
a concrete cavity poured into an underground or above-ground formwork.

With your own hands, the tank can be welded from sheet steel, aluminum, from cutting a large diameter pipe. The budget alternative will be presented metal barrel or old bath with well-preserved enamel, if it is planned to organize a temporary summer water supply system with an upper storage tank. For it, you still need to make a cover with a vent.

The drive material is selected based on the place of its installation:

in the upper scheme, a ready-made plastic tank or a metal container of our own manufacture can be used. The structure, on which the drive will be installed, must first be strengthened, because it will have to carry from 100 to 1000 kg of additional weight. If the tank is located outside, it must be carefully attached to the overpass so that after draining the water, the empty tank is not turned over by the wind;
in the lower circuit of bath water supply with a storage tank the best choice there will be a ready-made container made of food-grade plastic or eurocubes. A tank with concrete walls is perfect, which can also serve as a protective “shell” for a plastic tank. Concrete protection will protect the empty or half empty plastic product from ground pressure. Those. two in one is the perfect choice.

If the owners of a stationary bath water supply with a lower storage tank leave their beloved estate for several days in winter, the water from the underground reservoir can not be drained. It will not bloom because its environment resembles a thermos, and it will not freeze because the tank is below the freezing horizon. But cleaning an underground tank can create problems if the tank is not equipped with a maintenance hatch and the inlet pipe is not connected at the level of the bottom of the tank.

Membrane accumulator instead of storage

A hydraulic accumulator with a membrane is a high-tech descendant of conventional accumulators. His cost is not very humane, but he solves all issues with supply, water supply and pressure provision on his own. The membrane tank is a metal container, divided inside into two parts by an elastic bag-like partition-membrane. Air or nitrogen is pumped into one of the parts of the tank. Traditionally, a gaseous medium has a pressure of 2 atmospheres, but it can be adjusted.

When the pump is running, water fills the second part of the tank, stretches the membrane and compresses the gaseous medium, which, when the tap is opened, pushes water to the points of consumption. The hydraulic accumulator filled according to the specified parameters automatically turns off the pump. When the tank is empty and the pressure in the tank is reduced, the automation turns on the pumping equipment again.

The membrane tank is mounted in front of the branching of the pipeline. It can be installed in the caisson of the well, in the pit of the well or directly in the bath. At the entrance to the tank there must be check valve, excluding the flow of the injected water back into the source, at the outlet a pressure gauge to check the pressure. To remove air from the system, the accumulator is equipped with an automatic valve. The membrane tank works in dynamic mode, so you can not get carried away with too large internal volumes.

A membrane-type hydraulic tank is a very useful thing in the household, but not cheap. You should not take on its installation and configuration without having experience in this matter. Incorrect pressure setting may cause diaphragm rupture. The fastening of the device vibrating in operation must be very reliable. Without knowledge technological subtleties connecting the tank will disturb with a rather unpleasant sound. But the hand-made installation of a conventional storage tank for supplying water to a bath is very recommended and economically justified.

How to install a simple top drive

Let's analyze a common option with the location of the drive in the attic. So, we do it ourselves or choose a container that can crawl into attic hatch or window. Restrictions on volume and dimensions are not terrible for those who, while still in the process of construction, thought out a scheme for constructing a water supply system. Then the container can be pre-installed on the upper floor, if it does not interfere with the construction of the truss system.

Now we will analyze in detail how to install and connect a cold water tank to a year-round bath:

pre-strengthen the base by laying thick boards on the beams of the upper floor;
install the container in its place;
install the float valve. To do this, we mark a point, departing from the upper edge of the container 7-7.5 cm, and cut out a hole of the size we need. We insert the valve shank into the formed hole, after putting a plastic washer on it. On the other side of the tank wall, we first put on a stiffening plate, then a second washer and screw on the nut. We tighten the fasteners and screw the connector to the shank so that the supply pipe can be connected;
we drill holes for outgoing pipes according to their dimensions. FROM inside tank, we insert a connector with a plastic washer into each hole. We strengthen the thread by screwing two or three layers of FUM tape, after which we put on the washer and wind the nut;
we cut a shut-off valve into each outgoing pipe;
we make an overflow, for which we mark a point 2-2.5 cm below the marking point of the float valve and drill a hole. The overflow pipe is discharged into the sewer, we fasten it to the tank with connectors by analogy with the previous one;
we bring pipes to the tank and fix them by the compression method. We attach the newly created sections of the pipeline to walls or beams;
we fill the storage tank with water in order to check the tightness of the connections, at the same time we adjust the position of the float in accordance with the position of the overflow;
we insulate the container by attaching long pieces of polystyrene around to the walls or wrapping it with mineral wool.

In such a democratic way, you can organize cold water supply with a storage tank for a bathhouse. Essentially this general recommendations- a kind of information for reflection, which should be corrected according to technical features buildings.

Everything ingenious is simple! Even in the 21st century, where technical achievements are sometimes incredibly difficult to understand, there is a place for simple and ingenious inventions. One of them is a storage tank for water.

What is a storage tank and do you need one?

The storage tank is a simple, but very useful device, almost indispensable in the conditions of autonomous water supply. Even calling it a device seems wrong, because it is an ordinary container into which water is supplied from a well or well, and from where it subsequently enters a boiler or pipes.

It is difficult for city dwellers to understand what problems an illiterate arrangement of an autonomous water supply system in a private house can turn into. They live in an apartment that was originally connected to water, they have a hot shower, the opportunity to take a bath at any time, wash the dishes, start the washing machine, not to mention water heating - the designers, builders and utilities took care of everything. The source of water supply for a city dweller is the most reliable, and all problems with interruptions in the flow of water are not solved by him.

However, those who live in cottage and holiday villages know how difficult it is to organize a reliable and affordable source of water, to which you can connect a pumping station and get the necessary water pressure. Most often the conditions country house not so perfect, for example:

The house has a connection to a centralized water supply, however, water is supplied here not around the clock, but several times a week (this is typical for many summer cottages);
There is a well on the site, but its productivity is not too high - it quickly empties and it takes time to fill up;
Water comes from an artesian well, which is almost impossible to drain, however, only an automatic pump can be used to supply water, which is turned off in case of network outages.

The storage tank acts as an accumulator, storing water during the period when there is no need to supply it to the house.

Private water supply system with storage tank

There are two types of water supply systems of a private house with the participation of a storage tank - with an upper and lower tank. As the name implies, the fundamental difference here lies in the location of the tank relative to the water supply.

Water supply with top tank

The storage tank in such a system is located on the top floor of the house. It works on the principle of a water tower. The advantage of this option will be, first of all, the possibility of autonomous operation of the equipment. Water will flow to the water intake points in a natural way, without the use of a pump. However, one should not expect a strong pressure - as we remember, the height difference between the water source and the tap, equal to 10 m, creates a pressure of 1 atm. If we apply this to real conditions and assume that the tank will be installed in the attic two-story house with a ceiling height of 3 meters, the pressure in the taps on the first floor will be only 0.6 atm, and on the second floor - half as much. At the same time, we do not take into account the hydraulic resistance of the pipeline.

Due to the low pressure of water coming from the upper tank, such a system is recommended for use in country houses where the need for comfortable water supply is minimal. For permanent residence the house will need a more modern approach

In addition, a fairly large tank installed indoors will take up useful space. As summer version you can install the tank on the street on a special flyover, but this option is not suitable for winter. However, there is a way out here too - electric heating of the tank and insulation of the pipeline. Calculate how much this venture will cost you ... No, definitely worth looking for more rational solution! And, fortunately, it has been around for a long time.

Water supply with bottom tank

The lower tank is a solution for those who strive for comfort and know how to properly use the space of the site and at home. The tank is buried in the ground here. And even this plot of land you can use - by digging a tank half a meter below ground level, you get a site suitable for growing flowers or plants that are not related to root crops. The dimensions of the tank in this case are not limited by anything, and the larger it is, the longer it can cover the difference between the needs of the inhabitants of the house in water and the available resources.

Of course, there are cons, but they have a completely familiar form:

You will need pumping station to extract water from the tank and supply it to the house;
By placing the tank underground, you make cleaning and repair difficult to access - to make the task easier, make holes for revision and cleaning, and position the tank itself slightly at an angle so that the sediment masses accumulate in one place (preferably under the cleaning hole);
In winter, without insulation, the tank may freeze, and in spring, when wrong location will lead him.

A plastic tank buried in the ground should have either a round shape or stiffeners, if both options are not available, create a concrete shell around it

How to calculate the volume of the storage tank?

In counting required volume storage tank involved two quantities:

Water consumption. The average data will be here a very average value to start from it. Consumption depends on the set of possibilities for using water in the house and the number of inhabitants. Your home may only have a couple of sinks and a toilet, or it may also have Dishwasher, shower cabin, washing machine, etc. Of course, the difference between the two options will be great. In general, the consumption per person per day is about 200 liters of water in the presence of all the benefits of civilization. In conditions country house where water is used for cooking and washing dishes, this consumption is reduced to about 60 liters per day. However, it is best to calculate your expenses yourself;

Frequency of use. Measure your needs and the possibilities of your plumbing. You can choose a huge tank that will hold water for all your needs, but if the capacity of the system is not enough to pump enough water into it in the allotted time, the need for a large tank simply disappears. In addition, it is worth considering the reasons why you decided to purchase a storage tank - if it serves to insure against rare and short-term power outages (when powered from a well) or water (when supplied from a centralized water supply), a small tank will be enough for you.

Do not confuse a storage tank with a hydraulic accumulator, which serves to get rid of frequent short-term switching on of an automatic pump - it stores 25-100 liters of water and is used to conserve pump resources and extend its service life

What is the storage tank made of?

Accumulative tanks are made of food stainless steel or food plastic. In production, they strictly monitor the quality of the material, because it will be enough for a long time contact water, which will subsequently be used for food purposes.

Design features are:

Float valve mounted on the inlet pipe. If the house is used autonomous water supply, faucet replace float switch pump. To prevent emergency situations in the event of a float breakage, an overflow pipe cuts below the inlet, it joins the sewer;
A filter is also installed at the inlet, which is selected depending on the degree of water contamination - mud collectors are chosen for relatively clean water, and cyclones or centrifugal pumps are chosen for water with a large amount of sediment;
Also, a strainer is installed on the outlet pipe or right before wiring to the house;
If the tank has opaque walls, it is worth embedding a level into it;
Underground tanks are equipped with hatches for cleaning, and the upper tanks are equipped with a drainage pipe embedded at the bottom;
It is better to use a diffuser to fill the tank with water - this will prevent mixing and agitation of the sediment;
At the top of the tank, a ventilation pipe should be placed, bent at an angle to the ground. When the water is drained and there is no air access, the tank is deformed.

So, you have already made sure that the storage tank is indispensable for a private house. Whatever it is, one thing is clear - it definitely should be. Our consultants will help you choose the right storage tank, and it will be brought and installed by specialists who have been dealing with plumbing equipment for private houses for many years.

Cold and hot water plays a big role in everyone's life modern man. It is hard to imagine that a city dweller could do without a hot shower or without hot water for dish washing. To ensure a constant supply of water to the taps of private houses for domestic use, it is recommended to equip water supply systems. For this the best option will buy membrane tank for water supply.

Where can I use the structure for water supply

The tank in question, as well as the accumulator, can be used not only to accumulate excess water during the heating process. Thanks to them, you can maintain pressure in the system, as well as protect and protect against potential damage. If you decide to buy a hydraulic tank and install it, you can immediately feel its benefits. Water is supplied right up to the end, it works in a well-functioning manner, and the moisture that has accumulated makes it possible to turn the pump on and off much less often. Consequently, such equipment wears out much less. Buying hydraulic accumulators will also be the right decision, as an attachment to a hydraulic tank. Tanks can be used in systems where hot and cold water is supplied to houses, in those systems that are responsible for heating, for underfloor heating. In addition to domestic use, there are also larger tanks, they are often installed in cleaning systems, as well as where there are devices for extinguishing fires.

The main advantages of tanks for water supply

Buying an expansion tank for water supply in Moscow will be the right decision, since it is convenient to install, it is simple in terms of design, and easy to configure.

When water is heated, it does not come into contact with air, therefore, it stays hot longer. Due to the tightness of the entire tank, hot water loses heat in minimal quantities. It also saves on energy resources. Buying hydraulic accumulators in Moscow is easy, you just need to choose the right store for this. Choosing a tank for serving clean water for drinking, you need to specify what material the inner membrane consists of. It will be in contact with water. This is explained by direct contact. Installation and installation of the tank is convenient, you can always install it on the floor, hang it on the wall, or choose a flat version.

It is possible to buy a hydraulic accumulator for water supply systems in a store. There is a wide range that will allow you to choose what you need, and their cost plays an important role here. Hydraulic accumulators are very affordable in Moscow. If necessary, get advice from experienced managers who know the assortment both in theory and in practice. It is profitable to buy hydraulic accumulators for water supply in Moscow in a store that provides the most profitable terms for every client who came here. Goods of the High Quality, prices are reasonable, you can ask any questions by phone or just leave a request on the resource. You will be contacted as soon as possible and will help you make a choice if you are not sure yet.

Often, a water storage tank is needed for a house. When supplying water using a pump from a well or from a well, the system must similar device- hydraulic accumulator. He is the #1 helper for the pump. When supplied from a central water conduit, a hydraulic accumulator, strictly speaking, is not needed. But in both cases, the owners are not averse to acquiring a supply of water in the storage tank in the amount of 250 liters. Let's consider how this is achieved.

Water supply in the house - how much

Many agree that the average suitable amount of water in the storage tank is 250 liters. This is enough for mass flow, for example, for washing the car and cleaning, for filling the bath ... At the same time, the water will not stagnate, it will be exchanged faster and fresh portions will arrive. 150 - 200 liters is usually not enough (but with good well will do), especially if water is not often supplied to the house from the conduit - once a day or less. In this case, it is recommended to choose a volume closer to 300 liters.

Which storage tank to choose

Stainless steel metal or enameled water storage tanks are expensive. They are used mainly for storing a large supply of hot water. For cold water, tanks (with a food sign) made of polypropylene are more suitable. But here it is important to choose a quality thing, not made of “smelling plastic”, which is only suitable for purely technical water.

Such storage tanks are equipped with one large neck and can be different forms. More often, plastic containers for use as a water storage tank are chosen squat, with a large footprint.

Typical installation locations and piping schemes for water storage tanks

You can do it simply and install a water storage tank in the back room, in the bathroom under the ceiling. It can be suspended on cables to solid floor beams, or on a welded stand.
Water supply - tie at the top, here is a control descent into the sewer, tie at the bottom - water intake.
From the tank, a trickle in the taps will always be provided by gravity.

Most different ways install a storage tank more securely ...

You can increase the height by a meter - another and install a water tank in the attic (attic). If it is not heated, then it is easy to achieve non-freezing by covering it in a foam plastic casing ( wooden frame glued) which mates with the insulation of the floor. Under the tank, everything that significantly interferes with the access of heat from the house is directly removed. You can automate the filling of the water tank with a float switch, which is also achieved independently.

Installation on the floor or in the basement. Here you need a pump, which will create pressure in the water intake network. It usually turns on with a button. It is also possible that it is equipped with its own hydraulic accumulator and switch-on relay, which greatly simplifies the use of water from the tank.

Water is supplied to the house from a tank using a pump with an accumulator.

Hydraulic accumulator

The hydraulic accumulator not only provides rare switching on of the supply pump, but can also serve as a water reserve. The larger the device, the better, but the price also increases significantly. It is important that it can store water drinking quality- sealed system. The usual scheme for the house is a pump - a filter - a hydraulic accumulator - food water. The second branch is also connected here after the pump - a storage tank, which is filled under human control, but the analysis can be organized in any way, including with an additional pump.

Installation of an intermediate water storage in cold water. The tank is filled manually, after turning on the inlet valve (and the pump in the well ...) The analysis is equipped with a pump with a hydraulic accumulator for the same network.

water heater

Often in houses, as well as in apartments, without further ado, electric water heaters are installed. closed type, which also serve as water storage just in case. Installation is simple, but warm water maybe outside heating season regardless of heating...
