Situations often occur when the water pressure in the tap has become weak. Due to the thin stream, it is impossible to use the same washing machine or dishwashing equipment. Sometimes it is difficult to take a shower because of such water pressure. In our material we offer methods on how to increase the pressure in the water supply.
Causes of reduced water jet
To find out the source of a weak water jet, you should first go to the neighbors who live on the lower and upper floors and find out the situation. The information will provide insight into the situation regarding the overall pipeline system.
If it turns out that the water flows weakly only in one of the apartments of the riser, then that is where it is necessary to look for the cause. To do this, you should completely inspect the entire water supply system in the apartment.
Let's look at the main reasons why the water flow in the tap may decrease.
The pipeline is clogged
This is the most common reason. This especially applies to the wiring of old steel or iron pipes. Their walls inside are densely covered with plaque, causing the clearance to decrease. The walls themselves become rough. To resolve the issue of insufficient water pressure, new plastic pipes need to be installed.
Oblique filter clogged
It is usually installed in front of a computing device (meter) for water consumption. People called this device for filtering water a “mud collector.” Sand, rust particles and other debris can get into it. Sometimes it needs to be cleared of blockages and washed under water.
The aerator is clogged
A highly specialized device is installed in the drain - a filtration mesh. If it is clogged with debris, then this is also an important reason why the flow of water in the tap is significantly reduced. To correct the situation, just unscrew the mesh and clean it from debris.
If all the neighbors living in the same riser of a high-rise building have a weak stream of water, and others do not have such a problem, then the source lies in the common building water supply.
The supplied power at the mini-pumping station is also important. The power of pressure supplied to the pipeline mains of houses depends on it.
How to detect a problem?
Start troubleshooting by calling the appropriate services . This will allow you to determine if there are problems with the line. If they are not there, then you should move on:
- Talk to the residents of the house to see if they have similar difficulties. If low pressure also worries other people, then immediately contact the service. Sometimes this happens during a serious accident on the highway.
- Talk to the neighbors in the riser. Malfunctions may occur among individual residents of the house who are connected to a single riser. In the case of a new building, you should contact the developer. It is likely that the riser is not designed correctly.
- If the previous methods did not give a positive result and the malfunction is isolated, then the problem lies in the apartment. If the installation is incorrect, the pipeline will have to be redesigned.
The simplest is a clogged faucet. In this case, you will have to clean it or completely replace it. The drain can also be cleaned. This stage is very important, since further actions will depend on it. Some repair work requires considerable material and time investments.
The video explains what to do if there is poor water pressure in the apartment and how to find the cause:
Increasing water pressure in the pipeline
If you don’t want to wait for action from an authorized organization, then you can fix it yourself to increase the flow from the tap. After all, each management company (housing and communal services) has a lot of claims and the turn may not come soon.
To adjust the flow of a pipe, consider several methods below.
Installation of large diameter pipe
To increase the pressure and pass it through the system, you can install another pipe with a slightly larger diameter than it was before. After all, the pressure force and the direct movement of the water flow in the pipes depend on hydraulic pressure. If the pipe has a small hole, then the value of this parameter increases. The same applies to the speed of movement of water currents.
To correct the situation, it is necessary to reduce the hydraulic pressure and water flow speed in the water supply. Here you will need to install a pipe wider than it was before. Thanks to the increased diameter of the water conduit, the speed of the water flow will become lower, and the flow in the washbasin or shower will increase.
More and more apartment owners are choosing this technique to correct the situation with weak water pressure. True, it will still not be possible to achieve a radical improvement if the water pipes in the neighboring premises are clogged.
We use a pumping unit
To increase the water pressure in the apartment pipeline, you can use another method, for example, install small pumping equipment, which is sold in any hardware store.
Even the smallest device can eliminate the source of the cause that causes a decrease in the flow in the apartment pipeline. Ultra-compact pumps with high power can increase the water jet by 1.5 atm. This indicator is enough to comfortably use the apartment pipeline. Install a powerful pump after the tap valve.
To ensure sufficient pressure required for the uninterrupted operation of the device or equipment, a pumping system with good power is mounted directly in front of them. If desired, choose a model capable of increasing the water pressure by 0.8 atm.
The solution to the problem is to weaken the water flow using a mini-pumping station, which gives results if it is installed in a specific apartment.
For the pump to work automatically, it must do so in parallel with the sensor. When the jet meets the required parameters, the installation will turn off on its own. If the pump is turned off, the water flow can move completely freely in the pipe.
What numbers are considered low?
Before you begin to solve a problem, you need to establish whether it actually exists. Fortunately, indicators are strictly regulated by law. According to the information indicated in the regulatory documents, the pressure should be one atmosphere if we are talking about a house whose height does not exceed 10 meters. For taller buildings - not lower than 2 atm.
Precise regulations define the range that must be observed. From 0.3 to 6.5 atm for cold water supply, 0.3-4.5 for hot water. If the values are beyond the limits, this is a reason to write to the management company and demand that the situation be corrected.
Increasing water pressure in a high-rise building
For hundreds of residents of a high-rise building, weak water pressure in the kitchen or shower will be a significant problem. There can be many culprits for such situations.
The issue can be resolved by installing a pumping device with sufficient power - a mini-water station - at the entrance of the house pipeline system. If there is already one, then replace it with a new, more powerful one.
The mini-hydraulic pump is designed to supply increased water flow directly to high-rise buildings. These devices are equipped with several mini-pumps and systems that operate automatically.
The main task of water mini-stations is to reduce the workload in a temporary dimension when the hydraulic pressure in the water supply increases or decreases and deviates from standard indicators.
To install a similar pump on a high-rise building, all apartment residents will need to collect the required amount to purchase it. The organization will also have to pay for the installation of a mini-hydraulic pump. Installation will be carried out by specialists with extensive experience. After installing the home device, the problem with weak water pressure will be eliminated.

Increasing water pressure in the house
In a private home, you may also encounter a reduced flow in the tap. Although houses from the private sector are equipped with autonomous mini-hydraulic pumping stations. Typically, running water is supplied to the house by a pump from a nearby well or well.
If the pressure pumped by the pump is weak, then it is difficult to water green spaces, shrubs, and trees in the garden. Insufficient water will also have a negative impact on living conditions.
To solve the problem of low water pressure, storage tanks of various sizes are most often built in private courtyards and personal plots. The water supplied by the pumping unit will accumulate in them to the required volume. At the same time, stable pressure is maintained in the autonomous pipeline system.
Care must be taken to ensure that there is sufficient water level in the storage tank. Most often, this requires installing float relays. They will help you figure out what the liquid level is in the tank at the moment. An automatic device is also required to turn the pump off/on.
For an autonomous water supply system to work reliably and efficiently, it is important to install it correctly. Installation and configuration of equipment must be carried out in full. Main components of autonomous water supply:
- Pumping unit: borehole or surface;
- Hydraulic accumulator. The device contains a rubber bladder. The main task of hydraulics is to maintain the required water level over a certain period of time. For example, when the pump is turned off;
- Safety valve. Its task is to keep the water flow strictly in one direction, preventing reverse action;
- Elements that work automatically. For example, this is a relay, sensor. In a water supply system they are responsible for hydraulic pressure. If an emergency occurs, the pump should automatically turn off.
Self-configuration
Studying articles and videos on adjusting the hot water pressure reducer sensor in an apartment, it is easy to understand that the process involves a step-by-step implementation. In fact, it can be broken down into two stages.
Preparatory
Depending on the design features of the selected model, you may need certain tools:
- hexagonal slot 4-6 mm;
- regular flat screwdriver;
- special (universal) wrench for 2-20 mm;
- a pressure gauge that allows you to control pressure;
- adapter for connecting to a shower hose or faucet.
Direct setup
After careful preparation, you need to do the following:
- turn off all taps in the internal system;
- place the pressure gauge-controller on the regulator or connect it to the pipeline;
- using a valve, let the liquid flow through the pipe with minimal pressure;
- record the readings from the meter;
- unscrew the plug from the hole where the adjustment screw is located;
- taking a suitable tool (for example, a screwdriver), carefully rotate the screw element clockwise, as a result the spring will press on the valve and it will begin to slam shut with less atmosphere;
- to increase the flow force, it is necessary to rotate in the opposite direction;
- All that remains is to test the installation and disconnect the pressure gauge.
Selection and installation of a pump to increase pressure
To artificially increase the hydraulic pressure in an autonomous water supply system, you will need to install a pump. An important factor here is proper installation.
When choosing a pump, look at the following points:
- Length of footage of the water supply system;
- Number of floors of a high-rise building;
- Pipe diameter of the water supply system;
- The amount of water consumed per day.
When purchasing a water pump, it is important to pay attention to two factors - the power of the unit and its permissible performance. In addition, the unit must be made of high-strength material that is not susceptible to corrosion.
If necessary, you can additionally purchase a booster pump. Such units are not intended for installation in the private sector, where there are additional equipment that consume water. The price of a pump to increase water pressure is $40-200.
Some kits may include automated mechanisms, such as a flow sensor. It is responsible for automatically turning off the device when the water tap is opened. By the way, this helps save energy in the house. The price of the kit depends on the degree of protection and the presence of auxiliary elements.
It is necessary to buy pump models that have a high-quality filtration system. The device body is most often made of stainless steel, aluminum or cast iron.
It is advisable to purchase equipment from the store of the brand manufacturer. By purchasing directly, the buyer saves significantly. In this case, a free warranty is provided for several years, and you can also contact us for additional maintenance of the pump.
Models for supplying or increasing water flow may differ in control methods:
- The pump is in manual mode, ensuring uninterrupted operation. Here you need to turn the pump on/off yourself;
- Automatic pump. In this option, the device will automatically turn on/off the system. The unit is equipped with protection, so in dry mode (without water supply) it simply will not turn on. Its operating period is longer than that of a manual pump. Electricity is consumed more economically.
When choosing a pump to increase water pressure, it is important to pay attention to the dimensions of the device itself. It is completely inappropriate to install a device with high power if the daily water consumption is small. The pump can only be designed for cold or hot water.
Where to contact if a problem arises
Unfortunately, it is not always possible to correct the situation on your own. Many people do not have the necessary tools and skills. To solve this you need to involve professionals.
However, there is no need to rush. It's better to wait a few days first. If the low water pressure in the apartment remains so, you need to write a complaint to the management company. This is an organization that provides home maintenance at a specific address.
After submitting the application, employees come within 10 days and take all measurements using special instruments. If the indicators do not meet the standards, work is carried out to improve them.
Where to send a complaint
The authorities where the relevant document must be submitted differ from each other. It all depends on when this is done. If sending an appeal to the Criminal Code remains unsuccessful, you have to involve higher authorities.
The claim must be submitted to the management company in writing. It is recommended to prepare two copies. One is given to the department representative, the other remains with the applicant.
The law regulates the time within which authorities must respond to an application. This period is 30 days. If there is no response, the citizen has the right to go to court. Another option is the State Housing Inspectorate.
How to file a complaint about low cold water pressure in an apartment
Before you start writing, it’s worth going around your neighbors and asking if they have a similar problem. If other residents have a similar situation, you can make a collective appeal. Such acts are most often accepted and considered faster than applying alone.
The first step is to create an application to measure pressure in pipes. Within 10 days, employees of the management company are required to complete it. Next, a decision is made to carry out repair work. Qualified workers determine how to adjust the low water pressure in the apartment in order to achieve maximum results in a short time.
If within the period specified in the regulatory documents the management company has not taken any actions aimed at eliminating the problems, residents have the right to file a complaint. You need to contact one of the two authorities indicated in the section above.
What does a complaint look like?
In the text, it is important to indicate the address, personal information of the owner of the apartment or house, and also describe the problem in detail. In addition, it is necessary to indicate the documents on the basis of which the writer has the right to receive assistance.

Pressure pumps: main types
Pump rotors are available: dry and flow-through (wet). The elements of the wet unit are lubricated by the liquid passing through them. No additional maintenance is required during operation. The main thing at the initial stage is to install it correctly.
Although the dry rotor has stronger power, it needs to be maintained during the process. When turned on, the unit makes a peculiar sound in the form of a mosquito squeak.
Plus: the rotor elements are protected by a waterproof flap. Cons: They need to be cleaned occasionally.
Types of devices depending on the application:
- A pump capable of increasing the hydraulic pressure in a water pipe using manual operation. There are no automatic switches. Most often, the design is used if a “warm floor” system is installed.
- A device that automatically operates immediately after water is supplied. If the valve is closed, the pump will turn off.
For special installation of a circulating pump with pressure injection, you must perform the following steps:
- Turn off the water.
- Where the device will be installed, cut a section of pipe of the required size.
- At the joints, install fitting fittings for connection.
- Connect the pump to the pipeline.
Making a stream in a tap is no longer difficult. It is necessary to clean the pipe from plaque or replace it completely. Install a device that regulates hydraulic pressure in the drainage system.

Legal regulation
The required pressure in pipes is specified in legal acts, as well as Building Codes and Rules. They are relied upon when carrying out installation work and connecting the relevant equipment.
The main document is SNiP 2.04.02-84. It contains information about the minimum acceptable indicators. According to it, there should be one bar for every 10 meters.
In addition, the required numbers for communications are indicated. For a faucet installed in the bathroom, the value should not be less than 0.3 atmospheres, in the kitchen - 0.2, in the toilet - at least 0.2 atmospheres.
The legislation regulates not only the minimum pressure, it also stipulates the maximum indicator. It should not exceed 6 atm. If renovation work is being carried out on the building, an exception is made. In such a situation, 10 units are allowed.
Risks of emptying a well that has not been used for a long time
Often suspicions about the complete disappearance of water are erroneous. There may simply be so little of it that it becomes impossible to pump out the liquid with a pump.
Reasons for abandonment:
- Siltation, sand accumulation, soil collapse, which block the access of water to the trunk.
- Fouling of the internal cavity of the pipe with a layer of minerals.
- Violation of the integrity of the filter.
- Rare well operation. Water stagnates, and the walls and bottom become covered with inorganic deposits.
- Errors during drilling, installation and installation or during operation (cracks in the casing, lack of depth, incorrectly selected filter, etc.).
- Too powerful pumping of liquid from one aquifer. This happens when new wells appear in neighboring areas. Springs usually dry up in sandy layers up to 10 m deep.
New place. Feedback from Yegor Konchalovsky about the installation of a septic tank:
So, what to do when there is little water in the well or it disappears completely? If one of the listed reasons is detected, serious measures will be required to clean and pump the individual source. You can’t do this on your own without involving professionals. In addition, you need to be prepared for the fact that it will not be possible to restore the well and new drilling will be required.
Equipment
Reducers can be equipped with pressure gauges for visual monitoring of pressure and the ability to regulate pressure according to instrument readings.
Regulators can be produced in the same housing with a coarse filter. For use in pumping stations, automatic pressure regulators are used.
More modern gearboxes are equipped with an electronic unit that allows you to control the pump using an installed program. There are regulators with an electric rod drive that operate based on a signal from an electric pressure sensor. Such devices require a constant power supply.
Best models
A quick glance at the samples on offer is enough to form an idea of the brands in this segment. The cheapest (but often low-quality) products are from China. Price range from 450 to 800 rubles.
Following are the well-known manufacturers:
- Valtec,
- Uni-Fitt,
- Officine Rigamonti (OR),
- Itap,
- FAR,
- Stout.
All are made in Italy.
It seems that 80% of all regulators are Italian. In fact, most of them are produced in Russia. However, the quality of these products is not inferior to the original brands. The price range starts from 600 rubles.
Manufacturers from Germany are no less famous:
- Honeywell
- ProFactor,
- Watts.
However, the list of limitations here is short. The cost of their products starts from 1000 rubles.
The most expensive models are from Danfoss (Denmark), its products are of high quality, but prices are many times higher than those of competitors.

Preventive measures
In order to maintain well productivity within the established norm, prevention is necessary:
- Periodic pumping of the well, even if its flow rate has not decreased at first glance.
- Selection of equipment and components for the construction of a certain capacity, taking into account the flow rate of the aquifer.
- When constructing a well on sand, its diameter should be in the range of 15–21 cm.
- The casing must extend below the water level in the mine.
- It is extremely important to choose the correct mesh size for the filter mesh. There should be a sufficient number of perforations at the bottom of the pipe.
- The pump in a new well must be installed at least 1 meter from the bottom and 50 cm from the water surface.
- It is important to rock the hydraulic structure well. In the first days after startup, the injection equipment must operate continuously.
- The well should be used year-round, this will prevent siltation of the lower part of the shaft.
Problems with source flow can be avoided by following these simple recommendations.
