What a pressure in cold water. Water pressure in water supply: definition of norm

24.04.2019 Cead furniture

Many residents associate a plumbing system with a number of pipes located in walls and cranes, turning which water comes. And also most people have no idea about all the difficulties of the communication network.

Working pressure in the water supply system is one of the main indicators of the efficient operation of the water supply. All plumbing devices can function normally only with stable water pressure.

A weak pressure, which represents itself as slowly current water from the crane, indicates a low pressure in the communications network. In particular, this factor is worried about citizens who own apartments on the upper floors and residents country houses.

Weak pressure stops the operation of washing and dishwashers, shower cabins and baths. This article will review issues on pressure standards, as much as possible and minimum permissible indicator.

Normal indicators

The unit for measuring pressure in water supply pipes in the apartment and in a private house - 1 bar, which is equal to 1, 0197 atmospheres. This indicator fully corresponds to the mass of the water column in a height of 10 m.

The communication network requires a working pressure of 4 bar, which in turn correspond to the weight of the water column with a height of 40 m.

This indicator will provide water consumers all floors, including the topmost. But it should be noted that the stability of the indicator is extremely rare. Moreover, the pressure of 4 bars is not so often found. A typical water supply system implies pressure in the range of 2.5-7.5 bar.

A strong pressure and, accordingly, an increased pressure indicator leads to failures in the water supply, moreover, some plumbing devices are damaged with a 6.5 bar.

And even greater pressure is not at all able to withstand 10 atmospheres by virtue of only welded joints and fittings for industrial use, characterized by conical carvings. Just both high and low pressure leads to malfunctions and failures in the plumbing system.

Some plumbing equipment begins to work at a certain indicator, for example, the jacuzzi will function only at 4 bar. The shower and washing machine will require pressure from 1.5 bar.

In view of these features, 4 bars are considered to be a normal indicator. This border has minimal risks of damage to pipe connections and nodes and enough for the operation of various sanitary devices.

Pressure for autonomous water supply system

The autonomous water supply system functions completely differently and the standard generally accepted norms here do not have much importance.

In this water supply, you can set any pressure indicator, ranging from the minimum permissible, in which water flows almost by a self-sample (1-6 bar). In the case of autonomous water supply, the owner decides everything here.

The minimum allowable pressure for the country house is 1.5 bar. It allows at least to include two plumbing devices simultaneously. The maximum allowable indicator depends on the characteristics of the water source and the performance of the pumping equipment.

But most often residents of country houses are concerned about the problem of weak pressure, therefore many are interested in the methods of increasing pressure in the plumbing system.

Ways to enhance

It is possible to increase the pressure in autonomous water supply: with the help of cumulative capacity or pumping equipment. These methods have their advantages and disadvantages.

Pump equipment

This method is suitable for apartments with a central water supply system and for country cottages, cottage sites with autonomous water supply. Additional pumping equipment applies only if the main device does not fulfill the necessary requirements.

This is possible with the distant location of the well or insufficient power of the water supply to the second floor. An additional pump is installed at the entrance to the home wiring.

In the device, there must be a water pressure sensor that starts it with a normal indicator and turns off when there is no consumer. Most often used vibration pump, which is characterized by a weak sensitivity to high air content.

Station with accumulative capacity

This method works in a completely different principle: pumping equipment shakes water into the accumulative capacity, which functions with a stable pressure of 1.5-2 atmospheres. This means that the liquid is downloaded until the desired indicator appears, then the pump is turned off.

The water supply system in this case consumes water under the strict control of the pressure gearbox, the parameters of which are installed before operation. The pump in such a system will suit both vibration and centrifugal.

To injected pressure in the hydroaccumulator, an internal or outer ejector is used, which creates a discharge in the pipeline. This method does not apply in apartments due to noisy work and some design features.

Water supply pressure is an important indicator on which the functioning of most devices depends. But there are methods of increasing it, which are applicable in urban and rural areas.

One of the most important indicators High-quality work of the water supply system of a multi-storey house is the level of pressure. Too low or, on the contrary, the high pressure of water in the water supply system negatively affects the work of plumbing devices and household appliancesconnected to the water supply system, as well as entails a number of other problems. And if we can learn about the reduced pressure on the weak point of the jet from the crane, then the increased will know about yourself to know the leaks and the rupture of the pipes. Each owner must have an idea of \u200b\u200bthe number of bar of the pipeline within its own apartment in order to take action on time and avoid many inconveniences.

What should be the water pressure in the apartment?

Let's start with the fact that water pressure is measured in bars or atmospheres. Since 1 bar is 0, 99 atmospheres, these units are considered to be conditionally equal. 1 bar (1 atm.) Is able to create a water column with a height of 10 m.

There are documents in which the minimum and maximum allowable pressure in the pipeline are stipulated. apartment house (Snip 2.04.02-84, SNiP 2.04.01-85). Some of these norms relate to the pressure at the entrance to the building, others - at the entrance to separate apartmentThe latter stipulate the magnitude of the pressure in an intravartic wiring near the plumbing devices. We learn how much the water supply system should be on each site.

At the introduction of a water supply network in cottage The pressure should be 10 m of water column or 1 atm. (1 bar). For each next floor is added 4 m. We will calculate for a standard 9-storey building: 10 + (4 x 9) \u003d 46 m. \u200b\u200bSo the pressure at the input must correspond to 4.6 atm.
The pressure in the plumbing at the apartment will be lower than this value, since water rises to the above-mentioned floors on the complex pipe system. For cold water, the value should be in the range from 0.3 to 6 atm., For hot water - from 0.3 to 4.5 atm.
The level of water pressure at plumbing devices must match the following values:
- for a mixer installed on a washbasin - at least 0.2 atm.;
- to the toilet bowl - from 0.2 atm.;
- for the mixer on the bath - from 0.3 atm.;
- for a shower faucet - not less than 0.3 atm.

Necessary level of pressure for everyday needs

An important nuance is the fact that building rates indicate the extreme permissible borders, and it is impossible not to notice that the dispersion is very large. The minimum allowable pressure is not able to provide comfortable use of water in the apartment and normal operation. household appliances.

The optimal pressure in the intra-ordinary part of the water supply for cold water is 4 atm. In everyday life, this figure usually fluctuates within 2.5-7 atm.

Low pressure

If the pressure is low, then problems may occur even with such an elementary procedure as the adoption of the soul. With insufficient pressure, such devices such as washing and dishwasher, shower and jacuzzi will not function.

Normal level

What pressure will allow water supply with comfort?

Only 2 bar enough for such daily needs as:

washing and taking the soul;
washing dishes manually or with the help of a household device;
washing in a washing machine.

Some plumbing devices need a higher water pressure equal to 4 atm. Among them:

bath-jacuzzi;
shower cabin with hydromassage function.

The effects of increased pressure

With too high pressure - from 6.5 bar - the fittings and connections in the pipes suffer, at 10 bar they can easily endure and burst. Such high pressure is able to withstand only welded joints and industrial fittings. The pressure of 6-7 bar can also lead to violations in the work of highly sensitive plumbing, damage to the valves from ceramics.

Tip: When choosing mixers, cranes, pumps and pipes, it is necessary to take into account the possibility of sharp pressure surges in the network, called hydrowarders. To avoid unpleasant situations in the form of accidents and flooding, it is necessary to purchase devices and elements for installation in a system with an increased margin of strength: in normal operation, they must withstand 6 atm., But be designed for a short-term increase in pressure to 10 atm.

Causes of reduced pressure

Clogging of pipes with small garbage and deposit on the inner surface, which reduce the flow diameter. To eliminate this problem, you will need to replace the risers and intra-ordinary wiring.
Filter clogging rough Cleaning Or not to the end of an open input valve. In this case, you need to check the valve and filters. Perhaps it will only be enough to replace the grid on the filter so that water is poured as usual.
Break through the pipes of urban water pipes. In this case, the tenants of the apartments cannot do anything, it remains only to wait for urban services to restore the integrity of the water supply network.
Increased water intake by residents at home - is usually observed in the evening and morning hours when the water supply is particularly actively used.
Malfunctions of the pump on the distribution station or weak provision of its electricity.

In the event that you stopped laying water pressure, try first to determine the reason for its decline.

Ask your neighbors around the landing, whether they have problems with pressure. If they are all in order, it means that the reason is not in violation of general water supply.
Will the neighbors on the riser that lives the floor above and below. So you will learn whether the problem with a separate riser is connected. In the event that there is no complaints from the neighbors, the reason you need to search in the wiring inside your apartment.
Compare the pressure in different rooms Apartments - in the kitchen and in the bathroom, see if there is a difference between the jet of cold and hot water. Perhaps the problem is of a local character, and a certain section of the pipe clogged.

How to increase pressure

If all the measures to stabilize constant reduced pressure, such as the appeal to the HSEK or the replacement of intra-ordinary wiring and filters, do not give results, can be resorted to the installation of special equipment. There are two ways to increase pressure:

Connecting the circulation pump that increases the pressure by drawing water. it perfect solution For an apartment: the device has a small size, it can be mounted in a plumbing before water access points.
Installing the pumping station. Despite the advantage of such equipment in terms of power, this option has serious disadvantages: the station requires special coordination and takes a lot of space.

Reduced pressure

You can lower constant high pressure by installing at the entrance of the water supply in the apartment of a special gearbox, which will help adjust the water pressure. In order to monitor the pressure of the pressure, near the gearbox you need to install a water pressure gauge.

For the uninterrupted functioning of plumbing devices, it is necessary that the water pressure in the plotting corresponds to a specific indicator, which is usually calculated individually.

But faithful calculations do not guarantee that in practice water pressure will be optimal. Owners of country houses are most often faced with the problem of a small water pressure in the pipes. It is possible to solve it by implementing equipment.

We propose to understand what is the norm of pressure in the plumbing of the private house and for which reasons there is a decrease in pressure. Suggest effective methods Increase water efficiency. Material We completed detailed photo instructions and videos.

Residents of private houses are forced to calculate the pressure in the plumbing individually. In case the system is autonomous, the pressure may exceed the border permissible on the regulatory documents. It can hesitate in the area of \u200b\u200b2.5-7.5 bar, and sometimes reach 10 bar.

Standard values \u200b\u200bfor normal operation of the system C is the interval of 1.4 - 2.8 bar, corresponding to the factory setting of pressure switch indicators.

If you provide excessively high pressure in the system, some sensitive devices may fail or incorrectly operate. Therefore, in the pipeline, the pressure should not exceed 6.5 bar.

High pressure in the water supply can cause pipes, so it is important to pre-calculate the optimal level of pressure on your own

Fountaining artesian wells are capable of pumping out the pressure of 10 bar. Such pressure is able to withstand exclusively welded compounds, most of the fittings, shut-off-regulating nodes under its action are destroyed, resulting in leaks in areas.

It is necessary to determine what kind of water pressure is necessary for the normal functional of the country house water supply, it is necessary to consider the domestic appliances used. Some types of sanitary devices do not work at low pressure.

For example, for a jacuzzi, a pressure of 4 bar is needed, for the shower, fire extinguishing system - 1.5 bar, for washing machine - 2 bars. If you provide for the possibility of watering the lawn, then there should be a strong pressure in 4, sometimes in 6 bar.

Household plumbing devices connected to the water supply are capable of working exclusively from a certain pressure, which is usually not less than 1.5 bars.

The optimal pressure indicator for the country house will be the mark of 4 bar. Such a pressure is enough for good job of all sanitary devices. At the same time, the majority of fittings, knotting and regulatory assemblies are capable of withstanding it.

4 bar pressure can provide far from each system. Typically, for country houses, the pressure in the water supply is 1-1.5 bar, which corresponds to the selfotek.

Causes of low pressure in water supply

IN country houses Water in the plumbing network comes from or.

If the system is completely autonomous, then two points should be taken into account to create the desired pressure:

the need to ensure water lifting;
it is important to produce a hydraulic calculation correctly and implement it correctly in practice - to provide the necessary pressure in the points remote from the catchment and points located at different heights.

Two main problems of individual water pipes flow out of this:

Lack well resources - Debit holes does not allow to maintain normal pressure, and, consequently, to increase the pressure.
There are many water in the well, Therefore, the pumps can be pulled out high pressure (up to 6 bar), which can lead to the breaks of compounds, leaks, rapid equipment wear.

In the first case, the pumps swing fluid, creating its circulation until a certain pressure occurs, but over time it weakens. In the second case, it is necessary to choose a pump with a productivity, which is equal to the daily rate of water consumption.

From the flow rate directly depends on water pressure in the pipeline and its litter supplied for one pumping

However, most of the owners of private houses concerns the question of how to competently increase the pressure in their own water supply, and not to lower it, because only some artesian wells have a necessary flow rate for creating high pressure.

Most of the holes generate a weak water pressure, and they are not capable of producing any pressure.

If there are standard household appliances in the house, it is enough to lift the pressure to 2.3-2.5 bar - this wave is enough for their uninterrupted simultaneous functioning with good pressure. If a jacuzzi or irrigation system is provided, then a higher pressure is needed.

To measure pressure, the instrument is used manometer. It is bought separately and embedded at the point of entry of water to the house. Also, the water meter is also installed. Some equipment goes in a complete set with a manometer. For example, a heating boiler, if it is provided for HSV.

The principle of adjusting the pressure of water supply networks of private houses is the same as the autonomous system, is distinguished by the network only with dimensions

A simple pressure gauge has a scale from 0 to 7, which allows you to install it in an apartment, a private house.

Methods for enhancing pressure in the system

If the pressure in the water pipe is low, then the reason may be as follows:

Water in the pipeline is, but there is no pressure.
Water in the pipeline is absent on the upper floors.

To solve the first problem, it is necessary to implement the system that increases the pressure to solve the second to establish a cumulative station.

Before introducing hardware to the water supply system, you must first check the network for clogging:

# 1: Pump Implementing Pressure

If water in the pipeline is present, but there is no pressure, then the injection pump is installed. Also, the device can be implemented in case there is no pressure in the apartment with centralized heating.

The reason for the lack of pressure can be as follows:

the well is located remotely at home;
the power of the base pump is not enough to provide water to the upper floors.

The pump is usually mounted at the entrance to the home pipeline network in front of the collector or the first tee.

There is one lack of central pumps - they create a discharge, that is, they can swing water saturated with air. The usual injection centrifugal pump is sensitive to the air content in the liquid, so it is worth preferring to vibration modifications.

Water pump runs from the electric motor. The inner element rotates, thereby increasing the pressure in the pipes. The body of the device is usually made of durable plastic

To install the device in apartment house It is important to choose the modification of the loyal power, otherwise the owner of the "pumped" water supply will lower the pressure in neighboring apartments. It is recommended to put the pump on the pipe leading to a specific domestic instrument.

In general, the pump is cut into a common pipe, which is responsible for the flow of water in an apartment or a house. The device itself is quite compact and is inexpensive.

# 2: main types of injection pumps

There are models with a dry and wet rotor (flowing). Pump elements with wet rotor lubricates passing fluid. The devices of this class do not require additional maintenance, if you initially connect them correctly.

Electric pump, in contrast to vibration, is installed between the water supply and water source

A good capacity has a dry rotor pump, but it needs regular maintenance, it gives some kind of sounds when working, resembling a mosquito squeak. The details of it are fenced with the waterproof damper, so you will have to clean the device once a month.

By type of operation, pumps are divided into the following types:

pump, boosting pressure manual and having manual control. The model constantly works, does not have automatic switches. The device has a simple design for ordinary people; Most often, the device is used in the "Warm floor" systems;
automatic pump - It starts only when the crane or household appliances is turned on. After closing them, it turns off.

The automatic pump is more expensive than manual, consumes a little energy, promptly reacts to changes in pressure and today is the most popular.

Select the discharge pump is quite simple.

It is important to determine the following:

the device will be installed on hot or cold water;
the required level of pressure is the higher the indicator, the greater the pressure in the system.

Accordingly, the higher the pressure, the greater the power and capacity bandwidth.

It is equally important to choose a discharge pump taking into account the brand, because in case of breakdown, not each repair service will take into order a model of the production of an unknown company. The most famous and all recognized manufacturers - Grundfos., Wilo., Sprut.. Each firm specializes in the release of different modifications of the device.

The pump Wilo PB-401SEA is designed to increase the pressure in the water supply networks of housing. Can be installed both on the suction and submission

For example, Grundfos. Releases Circulating Pumps of Small Volume, Wilo. Develop models with built-in hydroaccumulator.

To connect the circulation discharge pump you need:

Relapce water on the site.
Release water from the pipeline and the system as a whole.
Cut off the pipe in which the installation will be made.
Attach fittings and nozzles to the place of joints.
Cut the equipment into a plumbing.

It is also permissible to use a polypropylene or rubber hose to simplify installation. In modern circulation pumps, such pipes are included.

# 3: Increasing pressure with a tank tank

When the pipelines are in the house without water or if the water is present on the lower floor, and it does not reach the upper, it is necessary to acquire a cumulative pumping station. It is also introduced into the system when the main pressure is less than 0.2 bar, and the flow rate is less than 2 l / m.

Any pumping station Works on one principle. Mount it at the point of pairing an external or inner branch of the home pipeline network

The principle of its work is next. The pump pumps fluid to the station (tank or hydroaccumulator), which operates under a pressure of 1.5-2 bars. Water enters the moment when the tank appears in 1.5 or 2 bars. If the station is equipped, the pressure being created may be an order of magnitude higher.

After generating the necessary pressure, the pumping station turns off automatically.

The design of the accumulative station introduced special pressure sensors. When the head is dropped to 1.5 bar, the main pump turns on, while increasing to a certain mark it turns off.

The system with the pump and the accumulative tank has many nodes, which makes it difficult to install it. So that the equipment worked correctly and smoothly, it is better to contact the specialists (+)

The pump in the station can be one of two species - or vibration.

By type of suction distinguish:

designs with removable ejector - Certain pressure per 5 bar. The ejector is immersed in the well, and the tank itself can be located at home, since it is practically no noise. The station is mainly used in cases where the water source is deeply located, and its disadvantage is the sensitivity to mechanical elements - sand, dirt, etc.
equipment with built-in ejector - Suitable for shallow (up to 8 meters) wells and wells, works effectively in dirty waternot sensitive to air intake, but differs in high noise, therefore it is usually installed in special extensions.

Models with cumulative tank are different in economy (the launch occurs when the tank is emptying), but have many drawbacks: generate a small pressure, they have large dimensions, there is a probability of a break, as a result of which the room can be flooded.

Stations with cumulative tank today are practically not used. On the replacement they came models with a hydroaccumulator. They have small sizes, no noisy when working.

Install the device can be installed in the basement, direction, separate an extension. This minimized the risk of leaks. But the hydroaccumulator has a small capacity of the tank (about 25 liters) and it is not used for wells with a small flow rate.

Pumping stations are often used in complex and extended water pipes as an increase in water pumping water from cumulative Tank Points of water treatment

Also share stations to superficial (when the pump is located on Earth) and submersible (the device is immersed in water), the latter are conventionally divided into well and well.

To increase the pressure level of water in the apartment pipeline, pumping stations do not use the characteristics of the design and noise during operation.

Despite its impressive cost, the pumping station has a number of undeniable advantages:

it is possible to establish any desired pressure in the house, which will allow you to use any plumbing devices, including those that require high pressure to function;
water supply will be uninterrupted even if it is absent in the central highway (due to the presence of a cumulative tank).

There are deficiencies in the system - she is cumbersome, takes a lot of space.

It is important to correctly determine the amount of cumulative capacity. Take this magnitude taking into account the average daily rate of water consumption. If the family consists of 3-4 people, then approximately 500 liters of water.

When calculating it is also important to take into account that water from time to time needs to be updated to avoid the appearance of bacteria.

If the water in the tank is enough (or the pressure in the system drops), the pump automatically starts, which pumps the required pressure on the network, and after reaching a certain mark it turns off

It is important timely and regularly clean the accumulative capacity, since pathogenic bacteria accumulates. Prevent their reproduction small bags with technical silver placed inside the tank.

It should be remembered that there should be no shut-off valves on the overflow pipe. If the float valve fails, the water will take place through it.

You also need to install bypass, so that in the event of a station breakdown, it was possible to turn off the system without a complete shutdown of water supply.

Conclusions and useful video on the topic

Roller # 2. The video describes the highlights when installing the injection pump:

As you can see, lift the pressure in the plumbing is easy. To solve the problem, an injection pump is used or a special pumping station. If the pump mounting is possible to be carried out on its own, then the station entry is followed by professionals.

It often happens that water from under the tap flows a small pressure. At the same time, it may not work at all or work incorrectly different devices (washing machines, water heating boilers, etc.), and in general, use water for swimming, washing something uncomfortable. So with what pressure, tap water should come to the consumer?

Norma pressure

The required pressure is normalized at several documents at once. SNiP 2.04.02-84 determines the minimum pressure at the entry into the building. For one-storey development, this indicator is 10 m (1 atm.), Each floor is added 4 meters. The same SNiP indicates the maximum pressure already at entering the apartment - no more than 60 m (6 atm.), If the value is higher, then the installation of regulatory mechanisms is necessary.

Directly at sanitary devices, according to SNiP 2.04.01-85, the pressure in hot water pipes should not exceed 45 m (4.5 atm. Or 0.45 MPa).

Resolution of the Government of Russia No. 307, describing the procedure for providing utilities to citizens, indicates that in cold water systems at the water parsing point, i.e. In each specific device (mixer in the bathroom, kitchen, etc.) the pressure must be in the range of 0.3-0.6 MPa. For hot water, this indicator is in the range of 0.3 - 0.45 MPa.

Causes of insufficient pressure

Emergency situations in the central water supply, as a result of which water is applied to the house with insufficient pressure;
Leaks and other faults inside the house;
Non-regulated water supply system in the house;
Old dried pipes;
Significant modifications of the water supply system produced by someone from the tenants. Water supply is calculated based on the configuration of the system, the number and species used by the plumbing devices. And if, for example, in a residential building, someone does not suit the original car wash, a bath or some other institution with a large water consumption, then naturally tenants will experience problems with pressure in the cranes.

In case of insufficient pressure, contact the management company and the utilities service that is responsible for water supply. Their representatives are verified, based on the results of which are required to eliminate the existing violations. For that period, when the pressure in the pipes did not correspond to the standards, i.e. The water supply service was improper quality, according to the already mentioned government decree, a change in fees for utilities in the direction of reduction.

Water B. modern house - This is something integral. Someone 20-30 years ago, people could easily live in uncomfortable houses and misfortunes did not know. But times are changing, today even in rural areas, almost every private house has a water supply. This markedly facilitates life and makes it better. But everything is fine when everything is fine. Water pressure is very important moment. Bad water pressure annoying almost more than its complete absence. Today we will talk about everything related to this point.

Water pressure in plumbing: standard

According to regulations currently operating in the country, 4 atmospheres should be the pressure in the water supply system of urban networks. Of course, no one will give ordinary consumers of the plumbing urban network of accurate information about these indicators. But you need to say, based on reviews, you yourself will realize when something goes wrong and the pressure in the system will decline much.

If you are from those people who do not give slack municipal services, and you want to get exactly 4 atmospheres for which you pay, you can install the water pressure sensor, that is, a pressure gauge. For example, it can be embedded in the system after a water meter in your apartment for tracking data.

A private house

If we talk about a private house and your own water supply system, where the source of water is a well or well, then here you are the owner. You can determine the pressure value in your plumbing using pumping equipment. Usually people try to adhere to the same values \u200b\u200bas in centralized networks, that is, the power of water pressure in their home is 2.5-4.0 atmospheres.

If you decide to overestimate the pressure, then consider that all the elements of your system (tube joints, washer, boilers, dishwasher and so on) should be moved normally. It is worth knowing that the pressure above is 6.5 atmospheres can damage the entire water supply system, it is critical! Such an indicator should not be allowed!

Old houses

Also we can talk about go home old builderwho or do not serve unfair communal communals, or these houses waiting in the wings, being in an emergency or dilapidated fund.

What is the water pressure in the plumbing of an apartment building in this case? This is a big riddle, no one will give a response. As a rule, people have to be content with what is. Or decide the issue with improved pressure own forces. It is about such ways that we will talk further. They are applicable in all houses, and not just those who are under demolition in the near future.

How to increase water pressure in plumbing

There are several ways to solve such a problem. The easiest is cleaning pipes. Or replace them, if cleaning is not possible or no longer help. If you have steel old pipes in your home or apartment, you may not even try to clean them. Most likely, when you dismantle them, the diameter of the channel for water in them is hardly exceeded by a centimeter, or even multiple times less than this indicator, the rest of the space will occupy, rust and so on. In this case, it is easier to replace the plumbing pipes than trying to raise water pressure in them. Change pipes is better for analogue of metal plastic or polypropylene.

If you have already changed pipes, you should be cleared, you can do it special chemicalswhich can be purchased in the store, and if it does not help, with mechanical means (rash and so on). It is worth noting that if the cleaning passes successfully, the water pressure will grow noticeably, the result will exceed your expectations. For some reason, traditionally, people believe in the apartment or house, people believe weakly. But only until this method tries this method.

Another way to obtain a good water pressure at home or in the apartment is the use of special circular pumps. Pressure increases are often used in apartment buildings. But this, of course, is a little dishonest towards your neighbors. Increasing the low pressure of water in your apartment will lead to a decrease in pressure in their water pipes. But there are no friends or neighbors in personal comfort.

The most important thing in this matter is not to apply about this act by your neighbors, otherwise they will come in the same way, while offended by you. And everything will fall into the "Arms Race" of the pumps, the winner will be the one who will have a powerful device. What water pressure in the water supply can be obtained using such a pump? Increase to the norm established by standards, you will definitely work. The main thing, choose the pump model is not the cheapest from the store presented in the assortment.

There are cases when the water pressure is quite suitable, but some kind of device (for example, a washing machine or dishwasher) refuse to work. Then the centrifugal pump can be installed directly in front of the device. It will not create problems with your neighbors. Also in this case, you can use a cheap pump, because the load on it will be minimal.

Collective complaint

If the water pressure is reduced and yours, and your neighbors, that is, it makes sense to file a collective application for solving the problem with relevant authorities. Why solve the problem to each yourself and at your own expense, when the general situation is obliged to eliminate special services? Of course, this business can delay, but in the end, it will decide in your favor, despite all the bureaucratic difficulties that will be waiting for you on the way to success.

Problems in private houses

Sometimes the cause of low water pressure in the private house water system is incorrectly selected equipment or incorrectly mounted system. The power of your pumping equipment for lifting water from a well or well may not be enough. It happens when you incorrectly chosen the pump model. It is recommended to take models with a reserve in power by about a third of the nominal stated by the manufacturer.

Also in your system may be too thin pipes. In them, the pump is difficult to pump pressure. It will constantly work under heavy load, and the water pressure will not please you anyway. It is recommended to choose pipes with a diameter of about inches (or more) for the normal functioning of the tap system at home.

Pressure may be reduced due to improper installation of pipes. Consider an example on a polypropylene water supply. Due to the wrong installation of the pipes, the inner diameter of the pipe decreases (part of the molten polypropylene goes intoward and thereby reduces the diameter of the pipe in the junction). Such a problem may occur only if the soldering technology is violated polypropylene pipes. The same nuances can occur with other material, so it is necessary to strictly observe the installation technology of the water supply.

After all, it is easier to do everything at once well than to redo what is done wrong. Good plumbing B. own home It can easily stop you up to several decades, and the line service will only be changed in the filter cartridges and cleaning the water source once a few years (well, well).

Suitable

Today we have disassembled questions regarding how to increase the water pressure in the water pipeline of the house or in the apartment. Methods exist, they are not so little. All of them are not too difficult in implementations. And they all give effect. What method stop? Only you decide to weighing all the nuances of each option.
