Winter water supply at the dacha.
DRAINING WATER PIPES FOR WINTER - 3000 rub.
Many gardeners build houses on their plots that are quite suitable for living in winter. How nice it is to enjoy the silence of the countryside and breathe in the clean, frosty air. What if you flood the bathhouse, take a steam bath and swim in the snow? This is great, but for complete comfort you need winter water supply in the country and sewerage. Many people already have summer water supply, but for winter accommodation will require significant revision. It is much easier to plan the system right away, starting from the drilling stage, but if there is already a water supply system, let's look at how it can be improved.
1. Well.
It is much better if you already have a well with a diameter of casing pipe at least 108 mm. Why is that? In the hole 40 mm. or 60 mm do not lower submersible pump, diameter is too small. To organize water supply country house from wells of small diameter it is necessary to use surface centrifugal pumps or automatic pumping stations. Why is this bad? Surface pump must be installed in a room with positive temperatures. There is no way to simply drain the system into the well. To start the pump, you must fill the suction pipe with water, which is VERY problematic in winter. For example, a 3-inch pump GILEX Poplar 3D 70/40 with a diameter of 75 mm. + the well adapter inside the pipe takes up 25 mm, a total of 75 + 25 = 100 mm, and there must also be a gap left, otherwise the pump will not fit into the well. It is the borehole adapter that allows you to connect to a well at a depth below freezing of the soil. Recently, Chinese pumps LadAna 2QGD 1-50-0.37 appeared on the market, which can correct the situation for owners of wells of 70 mm (the minimum diameter for this pump according to the instructions), but without a well adapter, only with the heating cable inserted into the well.
What to do if you have a small diameter well?
If you have good finances, drill a new well large diameter as close to home as possible so that there is no extra costs on the dig. If you have a small budget, use an existing well. It is worth noting that “narrow” wells are often very good quality and despite the diameter, they have good performance, quite sufficient for water supply to the cottage. How can our specialists help with the installation of a winter water supply with a small diameter well?
a) mandatory installation of a self-regulating heating cable into the well.
b) Installation pumping station in a heating cabinet, for example Balcony Thermal Cabinet Cellar-200. Slightly reduces station noise. The heating cables go directly from the heating cabinet underground. The heating cabinet will also accommodate a filter for mechanical water purification; it also does not have to be drained before leaving the dacha.
c) Installation of the caisson. Relevant for wells of any diameter, but in the absence of high groundwater. Reduces pumping station noise. Instead of a caisson, you can place the pumping station in a bathhouse or basement, so you will not be annoyed by the noise of the pump in the house. The caisson requires considerable financial investment.
2.Installation of winter water supply from a well.
The pressure pipe must enter the well in the same way as with a well at a depth below freezing of the soil. The entrance must be concreted and sealed with gasoline-bitumen mixtures to prevent it from entering the well. surface waters. If the area is swampy and there is only 1.5-2 meters to the water, then there is a risk of the well freezing. In this case, it may be necessary to insulate the well and construct an insulated cover. A trench is dug along the entire perimeter, the depth of which is at least 1.5 meters and lined, for example, with polystyrene foam. You can also build decorative house. The simplest thing is to run the heating cable directly into the well inside the pipe below the freezing level of the soil.
3. Pipe laying.
When supplying water to a private home from a well or borehole, the pipeline must be laid at a depth below freezing. In the Leningrad region, this is an average of 1.5 meters.
Loams, clays - 1.16 m.
Fine sands - 1.41 m.
large sands - 1.51 m.
If the trench depth is insufficient (for example, it is excessively flooded with groundwater or a limestone slab, etc.), a heating cable and insulation must be installed. Our specialists always install a heating cable inside the HDPE pipe, so heating is more efficient, there is no point in heating the ground; there remains the possibility of replacing the cable in case of breakdown. We put thermal insulation on the supply/suction pipe. We protect everything with a fan pipe or corrugated sleeve. We perform pressure testing of the corpse pipe before digging the trench.
4. Entering the house.
Depends on the foundation. If the house has a basement, then there is no problem. If the house is on a pile or strip foundation, then the entrance to the house is always at risk of freezing. In practice, there is no constant water supply during the day; at night the taps are closed and no water flows in the pipe. So winter nights This is the most dangerous time for standing water to freeze. Insulation and heating cable installation are always necessary.
5.Insulation fan pipe.
Heating sewer pipe This is done by wrapping a cable around it and putting on insulation. Relevant for pile foundations with the installation of a waste pipe under the house. Insulation is required when the pipe slope is too small, where water can stagnate.
6.Using a compressor.
If you often leave your cottage for the city, and the electricity in your village is cut off for a long time, then you need to blow out the pipes with air and drain the boiler. To do this, the system provides for the connection of a stationary compressor with an appropriate valve. You open the taps, turn on the compressor and after 10 minutes you can go about your business without thinking about the fact that the pipes will burst due to freezing. This method is suitable for a system with a submersible pump. Can be combined with the method from step 7.
7. Installation drain valve.
Auto drain valve G15 or valve for automatic winter water drainage (for example, Gilex water drain valve, Debe automatic winter water drain valve, EMS automatic winter water drain valve Dellain (Sweden), Belamos automatic drain valve for well FV-B1/2”). Its main advantage is that it does not require human participation in the water draining procedure (except for Gilex). He works very simple principle. The fact is that when the pump is turned off, the pressure in the pipe drops, and when it drops below 0.5-0.9 bar, the drain valve opens and releases water back into the well. When the pump is turned on, the pressure increases and the valve closes again.
8. Draining the system for the winter.
The simplest solution is conservation of country water supply systems. You just call us and we will blow out the system with a compressor, drain the boiler and hydraulic tank, undock and drain the pumping station, disassemble the filters, thus preserving the water supply for the winter. Only 3000 rub.
In the installation of summer water supply systems we provide:
As you can see, there are solutions. Our company is ready to help you modify summer water supply in the winter or create a winter water supply from scratch, so that it doesn’t look like the picture below. =))
We are happy to help you if you don’t have time to do the plumbing in a private house with your own hands!
When going to a dacha outside the city, few people are ready to completely abandon the benefits of civilization, especially if we're talking about about the water supply. Agree, the importance of water supply summer cottage plot difficult to overestimate.
Water is necessary for watering the garden and vegetable beds, as well as for solving everyday problems. What can we say about using household appliances requiring connection to the water supply network. To arrange the water supply, you can hire specialists or do it yourself.
To make water supply at your dacha with your own hands, you must first decide on the source of water, select necessary equipment and materials, study the sequence of work. These are the questions we will help you solve.
For a better understanding of the water supply process, we have illustrated the material visual diagrams and photographs, supplemented the information with video clips.
The installation of any water supply system begins with the selection of a water supply source. Although the choice is usually not great. It could be centralized system water supply, .
Not only its quality, but also the methods of constructing the entire plumbing system, its technical complexity and cost.

Winter plumbing is a much more complex system. Everything must be taken into account - from the natural slope of the terrain to the depth of soil freezing. A pump is required to provide water pressure. In short, a winter-type country water supply system is no different from the water supply system for residential private houses.

To organize water supply at the dacha, water from a well is most often used. An autonomous source allows you to organize your life with all the benefits of civilization. To avoid having to carry water in buckets, summer residents install a water supply system. If Vacation home exploited all year round, it will be necessary to ensure the laying of communications that prevents water from freezing during negative temperature. Do-it-yourself winter water supply from a well must take into account all requirements and building codes.
Well - an autonomous source in the country
Dig your own source - for many summer residents this is the only opportunity to provide for themselves and their garden life-giving moisture. For autonomous water supply construct a well or borehole. The first option is easier to arrange with your own hands, so this is what they choose for their dacha. Among the advantages of using a well:
Considering the many advantages hydraulic structure, we must not forget about the disadvantages:
At the water supply design stage, it is necessary to decide which system option to choose - for summer or year-round use. A seasonal water supply system requires less effort and implementation costs. Do-it-yourself installation of a winter water supply from a well is carried out according to special requirements:
Well water supply diagram
Attention. Standards for pipe laying depth depend on the region. You should focus on data on the level of soil freezing.
Timely insulation of the winter well will help avoid problems with freezing of the underground section of the mine. The formation of an ice crust leads to negative consequences:
Attention. The rate of freezing of a liquid depends on its level; the higher it is, the sooner ice forms.
The structure can be insulated with slabs of polystyrene foam or other material with similar properties. To ensure effective insulation, the rings are dug out to a depth of 1.5 m, and then covered with insulation and covered with earth. This option has several advantages:
Expanded polystyrene is used to insulate the well
Installation of a wooden well house is an effective, but expensive method of insulation. Wood serves as a good heat insulator, eliminating the risk of freezing in the upper part of the shaft. Original wooden structure besides practical use it serves decorative decoration summer cottage plot.
Such a house is one of the options for insulating a water supply source
One of the methods for protecting a source from winter frosts– spraying polyurethane foam on the outer part of the barrel. This results in a durable monolithic layer that reliably protects concrete rings by cold. The work is quite labor-intensive; you will have to dig a shaft 1.5-2 m deep, and fill it up again after the foam has hardened.
Polyurethane spraying
Attention. If the length of the straight section of the highway exceeds 30 m, then the installation of a manhole will be required.
At the design stage, a water supply system diagram is developed, the quantity required material. For reliable water supply, the system must include the required elements:
Water supply scheme
These elements make up any water supply scheme. The winter option requires insulation of the pipeline and the pit in which the pumping equipment is located.
To prevent water supply from stopping in winter due to ice jams, pipes are laid below the freezing mark or insulated. The first method requires digging a ditch up to 1.5 m deep. A sand layer 10 cm high is poured onto the bottom of the trench; it will ensure soil stability. It is better to choose pipes made of polypropylene; this material is not subject to corrosion like steel and is not afraid of pressure like polyethylene. Among the advantages of the products:
They are laid at a slope of 3 cm by 1 m, directed towards the well. Optimal diameter pipes 32 mm.
Pipeline trench
Advice. On top of the main line, place an insulating layer of up to 30 cm of expanded clay, slag or broken brick.
Piping in a house is carried out in one of 2 ways:
If the terrain features do not allow the pipeline to be lowered to a sufficient depth, then a trench of 50-60 cm is dug and insulation is performed. You can insulate pipes from frost using solid and soft materials. Rigid insulation for pipes is a foam shell, characterized by an affordable cost and excellent thermal insulation properties. Other materials are also popular as soft energy-saving shells:
Insulation materials are not susceptible to low temperatures and are easy to install. Simply put them on the pipe and seal the seam with metallic tape.
Pipe insulation can be soft...
...and tough Attention. For pipelines in regions with cold climates, a pipe with ready-made factory insulation and a channel for installing a heating cable is recommended.
Pipe with heating cable
If pipes are laid close to the surface of the earth, they are at risk of freezing. Thermal insulation materials partially protect the pipeline from low temperatures, but cannot withstand severe frosts. The most unprotected area is the point where the pipe passes through the foundation of the dacha. The water temperature at the entrance to the house is close to zero, so additional insulation is required. Ensuring uninterrupted water supply will allow the use of heating cable. For installation on a water supply system, 2 types of devices are used:
Self-regulating cable
The heating cable can be laid along the entire length of the winter water supply, but this is an expensive procedure. You will need to buy a cable and protective thermal insulation. To save money without sacrificing quality, it is enough to install a self-regulating cable at the point where the pipeline enters the building.
Winter water supply is necessary at the dacha if you are going to be there regularly or live there.
It can be used not only in winter, it will be relevant at any time of the year.
It is also noteworthy that such a device at the dacha will not stop functioning, even if you do not visit it.
If you have to drain the water from the pipes at your dacha every time so that they don’t freeze, winter is The best decision.
It will not freeze because it is laid below the freezing depth - which is usually below 2 meters.
The main devices are:
Pipes for winter water supply
It is better to choose polypropylene pipes, because they have a number of advantages:
Installation is performed by thermal welding, which ensures the integrity and safety of the entire system.
Surface or submersible pump for winter water supply
The best option will be use . It supplies water well to the system and is economical.
You need to choose the brand yourself, which depends on the depth of the water source and the type.
Natural cooling of the engine is carried out automatically, and during operation it does not create any noise.
Drain valve for winter water supply
The valve is installed after the pump, and the water can be drained into a source or into a well.
You can build a bypass pipe instead of the drain valve. This option is good when the winter water supply is located near the house.
Pressure switch for winter water supply
The device is necessary to maintain the pressure in the water supply within a certain range.
When the maximum pressure is reached, the relay will turn off the pump. If the pressure drops to a minimum, the relay will close the contacts and the pump will resume operation.
Hydraulic accumulator for winter water supply
This device will protect the water supply from water hammer and stabilize the pressure.
If it suddenly turns off, you will still have water, since the water that has accumulated in the tank will enter the system.
It is better to use a hydraulic storage tank with a membrane.
Winter water heater
In practice, this process is best handled storage water heaters.
The power and volume of the boiler must be selected based on your water consumption. Typically, for a family of 5 people, 100 liters with a power of 2.5 kW is enough.
If winter water supply is carried out near the house, then you will need a water heating cable. It can be placed in the basement or under the floor.
There are only three options here:
The most convenient and easiest way is winter. It has a number of advantages over the above:
To drill a well, you need a decent amount of money, and its maintenance costs even more, therefore, winter water supply from a well is a profitable way to obtain hot water.
Winter water supply project
Without a project and diagrams, it is almost impossible to create a proper water supply system.
It is important to consider when creating a route design and the location of connections to the plumbing.
Here are examples of diagrams and projects you can use
If you want to do it yourself, then you need to stock up on basic tools:
Laying pipes for winter water supply
First you need to dig a trench. Since we are talking about creating a winter water supply from a well, the depth of the trench should be up to 2 meters.
It is imperative to make a slope in the direction of the well.
Laying it down polypropylene pipe into the trench and connect it to the pump.
We seal the pipe coming out of the well with liquid glass. This will prevent your well from flooding with groundwater.
After the pipe is laid, we fill it with 15 cm of sand, and top it with the soil that remains after digging.
If you have dug a trench to the required depth, there is no need to insulate the pipes. If it is not possible to dig the required depth, put insulation at the bottom of the trench that does not absorb water (slag, expanded clay) and lay the pipe on it, covering it with a 30 cm layer of insulation on top.
Fill with sand or soil and compact.
Now you will always have warm water!
After the well is built, it is necessary to take care of installing the water supply. If a country house is used all year round, then winter water supply from a well will be needed. In order to carry out the entire process yourself, you need to know about the possible nuances and risks associated with connecting the pump and joining the pipes.
IN in this case, the word “winter” means year-round.
If we talk about winter water supply, the water will not freeze if one of the special methods is used for installation:
Advice. If the depth of soil freezing is up to 0.8 meters, then you can use the first method.
Winter water supply to a well, more details about the methods:
Sealing and winter water supply from a well:
Advice. If HDPE pipes with a diameter of 32 mm are used, it is recommended to install an adapter fitting for joining. In order to connect the pipes to each other, you will need soldering or fittings.
Advice. In order to supply water to a dacha from a well in winter, the immersion depth of the pipe must be below the middle of the water level. If the pipe is brought too close to the bottom, the pump may become clogged.
Pipe installation:
Winter water supply can be done in several ways. Here it all depends on how often the country house is used: all year round or we are talking about periodic operation with the ability to start the water supply at any time.
Let's look at each method in more detail:
Advice. In this case, it would be advisable to install check valve right in the house, and the pressure will be created when the pump is turned on. To drain the water, you will need a bypass pipeline.
