Some Helpful Tips

Not always a booster pump is needed to solve the problem with low water pressure in the system. To begin with, it does not hurt to diagnose the condition of the water pipes. Their cleaning or complete replacement can restore normal pressure without additional equipment.

To understand that the problem is in the poor condition of the water pipes, sometimes it is enough to ask neighbors who live in apartments on the same floor or higher. If they have normal pressure, you almost certainly need to clean the pipes. If the picture is the same for everyone, there may be more serious problems affecting the entire plumbing system of the house and even the area.

In high-rise buildings, water sometimes simply does not flow to the upper floors. This requires high-powered and rather expensive equipment. It makes sense to cooperate with other tenants to share the costs.It is a good idea to demand that the organization that receives the payment for the water supply solve the problem, since it is they who must ensure the supply of water to the consumer.

The lack of water on the upper floors is a violation of fire safety requirements

When communicating with the water service provider, it is worth paying attention to this point and mention the possibility of litigation due to non-compliance with the law

It is best to entrust the installation of equipment in an apartment building to a full-time plumber of the management company. He is also more familiar with the system, and will be held responsible in case of leaks or breakdowns caused by poor-quality installation of equipment.

Self-priming pump stations

If the apartment is located closer to the top of a multi-storey building, then residents may be completely deprived of water. To get rid of this problem, you can use a self-priming pumping station. The composition of such equipment includes a pressure boosting pump, a pressure switch and an accumulating membrane tank. There may be no hydraulic accumulator, but with it the device turns out to be more reliable and durable - the accumulated water allows the pump to start less often.

The tank is filled with water by means of a pump. The pressure in the tank is regulated by a relay and allows you to supply water to the water intake points. After the liquid has entered the tank, the boost pump for water is turned off. Even if there is no water in the pipes, it is quite possible to use the previously accumulated stock. After emptying the tank, the relay restarts the workstation. Self-priming pumps are successfully used not only in apartments, but also in private homes.

Wilo PB-088EA

This unit is quite compact and is equally suitable for transporting both hot and cold media. The equipment is cooled by the liquid passing through it. The device can operate in automatic and manual mode. Automatic mode is activated by a special sensor that monitors water consumption. The Wilo pump is resistant to overheating and makes almost no noise when pumping liquid.

The performance of this model is as follows:

• Limit pressure - 9.5 m;
• Temperature limit - from 0 to +60 degrees;
• Power - 0.09 kW;
• Productivity - 2.1 m3 / hour;
• The diameter of the inlet pipes is 15 mm or ½ inch.

Injection pump installation

The connection process is simple and includes the following steps:

• Turn off the main water supply valve and drain water from all pumps. Valves must be left open to release trapped air;
• Cleaning the inlet water pipe, to facilitate the installation of fittings;
• Using a pipe cutter, cut the pipe into the water supply line;
• Connect the booster pump, as well as all the fittings that will come out of it to the existing water supply line;
• Cleaning fittings with sandpaper;
• Applying flux to joints and soldering parts.
• Make the connection to the electrical panel (possibly with the help of a professional electrician);
• When ready, open the water supply valve on the meter, and let the mixers run for several minutes to release the air inside the pipes.
• Check the pressure indicator to see the effectiveness of the design.

Features of installing a device for pressure in the water supply

The installation location of the pressure boosting equipment depends on the specific situation. To ensure the normal operation of the faucet and shower head, it is enough to mount it at the outlet of the storage tank. For devices that are more demanding on pressure (washing machine, dishwasher, water heater), it is better to install the pump in front of them.

However, installing several low-power pumps at once is not the best option. In this case, it is worth installing more powerful models that can stabilize the pressure at high flow rates.

Installation booster pump pressure in the water supply of an apartment or a private house is performed in the following sequence:

First, mark the pipe on which the equipment will be installed, taking into account the length of the device and fittings.
Then the water supply is shut off in the room.
After that, in the marked places, the pipe is cut.
At the ends of the pipeline, an external thread is cut.
Then adapters with an internal thread are mounted on the pipe.
Fittings from the kit with the pump are screwed into the installed adapters

For better sealing, wind FUM tape around the thread.
An increasing device is mounted, while it is necessary to follow the instructions of the arrow on the body of the device, showing the direction of water flow.
After that, from the electrical panel to the device, you need to stretch a three-core cable and, preferably, make a separate outlet, and it is better to connect the device through a separate RCD.
Then the pump must be turned on and its operation checked, paying attention to the absence of leaks at the joints. Tighten the fittings if necessary.

Proper installation of the device will provide water needs for many years.Adhere to the following recommendations during the installation of equipment:

• in order for the pump to work longer, it is better to install a mechanical filter at the inlet to it. So you can protect the device from getting into it unwanted particles;
• it is better to install the unit in a dry and heated room, since low temperatures can freeze the liquid in the device, which will disable it;
• vibration from the operation of the equipment, over time, can loosen the fasteners, causing a leak, so sometimes you need to check the connections for leaks.

A properly selected and correctly installed device can solve the problem of low pressure in the water supply.

Connection diagram - recommendations

When determining the location for the optimal location of the pump, it is guided by the following considerations:

1. For the correct operation of household appliances in the form of a boiler, washing machine or dishwasher, the pump is placed directly in front of them.
2. If the house has a storage tank located in the attic, pumping is placed at its exit.
3. As with the installation of circulation units, in the event of an electric pump failure or removal for repair and maintenance work, a bypass with a shut-off ball valve is provided parallel to it.
4. When installing a pump in apartment buildings, it is likely to leave residents without water in the riser, dramatically increasing the volume of its consumption when the pumping is turned on. In this situation, it is necessary to provide for the placement of storage tanks in the apartment, which are more practical to hang from the ceiling.
5. Many, when installing more powerful units in a line, do not get the desired result indicated in the passport data.Not knowing the laws of hydrodynamics, they do not take into account the increased hydraulic losses in the pipeline with an increase in the volume of pumped liquid - to reduce them, it is necessary to change the pipes to a larger diameter.

Rice. 14 Installation of booster pumps in the internal water supply

Booster electric pumps are usually installed in apartments or private houses when using public water supply networks, whose services do not fulfill their obligations to create working pressure in the system. Standard wet rotor household units increase the pressure by an average of 0.9 atm. To obtain a higher figure, it is necessary to install a centrifugal electric pump, a pumping station or an installation with frequency control of the impeller rotation speed (the best, but too expensive option).

Model selection options

The main characteristics to consider when choosing are the flow rate, cooling method, calculated pressure increase and power.

By type of cooling

The required head is determined by the type of cooling system, which can be wet or dry. In this case, they are guided by the nominal value of the required pressure (usually from 5 to 15 m).

Note: When cooling with fresh water, cooling rate, heat exchanger characteristics, flow and head ranges are taken into account.

With air (indirect) cooling, cooling occurs with an air jet. The specific flow rate of the coolant is about the same, but a more sophisticated ventilation system is required.

By type of constructive solution

The features of the use of units of various designs have already been described above.In particular, circulation models are characterized by low power consumption, but are unable to increase the pressure by more than 3 atm. For higher values, self-priming or vortex designs should be adopted.

Rules for selecting the power of the unit

The main parameter of the pump for water pressure in the pipeline the maximum flow rate is considered, which describes the maximum achievable volumetric flow rate through the pump. The highest pressure increase indicates the maximum achievable addition of pressure to the existing pressure or head of the system. The pressure to be supplied by the unit is the difference between the required system pressure and the nominal pressure. This pressure difference is expressed as the volume of liquid that must be supplied to the booster pump at the desired flow rate to meet the requirements.

In order to select the required pressure, it is necessary to take into account the additional losses within the plant and in the system due to changes in friction and flow conditions.

It is used mainly as a downhole pump, but can also work as a booster pump. It is characterized by good build quality and undemanding to water quality.

Comfort X15GR-15

Of the advantages, it is worth noting the democratic price, low noise, reliable automation, the ability to work on hot water. Of the minuses - a short installation cord, a meager selection of accessories, a low level of pressure increase in the network.

What are the pumps that increase the water pressure in the water supply

An additional way to increase the pressure in the system is to install an electric pump.Pumping equipment is selected based on the following criteria:

• the length of the water main;

• the diameter of the pipes used;

• height of water supply;

• required daily cubic capacity.

The main functional indicators of the pump are its performance and power. These parameters are indicated in the instructions, and are also usually encrypted in the pump model index. The quality of workmanship and the materials used are the main criteria for choosing a pump.

A booster pump should not be used in private homes that have additional equipment that consumes water.

The range of prices for pumps is from 2500 rubles to 12 thousand rubles, depending on the brand of the manufacturer and the power of the pump. Pumps come in different configurations. Additionally, the pump can be equipped with a flow sensor, as well as a check valve that protects consumer devices from water hammer.

In addition, there are pumps with automatic shutdown and variable power. Such functions save on electricity and extend the life of the pump, as they reduce its operation time and power to optimal values. Additionally, the pump can be supplied in a moisture-proof design or be equipped with a water purification filter.

To increase the pressure, one must also take into account the modes in which the pump operates:

• manual control implies continuous operation of the pump without stopping. Human presence is required to switch on and off;

• automatic mode is a privilege of more expensive models. They turn on and off independently based on the readings of sensors built into them or additionally equipped separately. The pump has a longer life because it only works when needed.Accordingly, the device does not have idle overruns.

The pumps differ in the type of housing cooling and overheating protection:

• cooling due to the blades of the shaft provides a high efficiency of the mechanism, while the noise level is quite low. The operation of such equipment can be checked visually. The disadvantage is that such a pump is undesirable to use in dusty areas;

• liquid cooling of the pump ensures its complete noiselessness. However, such a pump is usually less powerful.

When choosing a pump, consider its size. Because sometimes it is impossible to fit a large machine in a small room. There are pumps used only for hot or only for cold water, as well as universal ones.

When choosing equipment, decide on its characteristics such as:

• the amount by which it is necessary to increase the pressure;

• complexity of equipment installation;

• nameplate capacity and performance of equipment;

• dimensions of the pump and accessories;

• cost of equipment;

• necessary additional features and characteristics.

For water filtration

There are methods for water purification:

• mechanical;
• reagent;
• chemical.

But at present, the reverse osmosis water treatment scheme is becoming more and more popular. Based on the membrane method, in which water is purified from impurities.

When is a pump needed?

Pumps for reverse osmosis systems are used if the pressure in the pipeline is below 2.8 atmospheres, which is necessary for the operation of the installation. If the pressure is below the required value, the unit will shut down.

The reverse osmosis scheme with a pump differs from the usual one only in the presence of a pump. The reverse osmosis pump is equipped with high and low pressure sensorsthat turn off the device when needed. The device also has dry run protection. If the liquid storage tank is full, then the sensor turns off the pump, and when the water starts to be consumed, it turns on the pump again. The operating voltage of the pump is 24 V and 36 V. The voltage transformer converts the mains voltage into a working pump. Models of transformers differ in different types of pumps. A reverse osmosis system with a pump allows you to get clean water around the clock. to the menu

Which pump that increases water pressure is better according to the editors of Zuzako

Pumps that increase water pressure are divided into two groups. There are models with a dry rotor, and there are devices with a wet rotor. Both groups of devices have their advantages and disadvantages, so it's up to you to decide which is better to choose.

Wet rotor models are more compact and symmetrical. They work very quietly. The advantage of products of this type is that it is not necessary to regularly carry out preventive measures. The parts inside the device function by washing the shaft with water. The fastening process is very simple, since in this case a tie-in is made into the pipeline itself. However, the performance of wet rotor pumps is quite low. In addition, they have weak indicators of maximum water pressure. You should also know that the installation of such a device is carried out strictly in a horizontal plane with respect to the axis of the rotor.

Models with a dry rotor have an asymmetric appearance.In the case of these devices, cooling occurs due to air flows from the impeller. To mount the device to the wall, additional parts are required. Models with a dry rotor require constant preventive measures, which consist in the timely lubrication of rubbing parts. The noise level during operation of such products is quite high. But the performance of such devices is at a high level.

Pump for a private house

For a private house, it is best to choose either a submersible pump or a full-fledged pumping station, especially if the device must perform its functions year-round. In this case, you should carefully look at the products of Gileks and Whirlwind.

The pumping station consists of the pump itself, a hydraulic accumulator and automation. A hydraulic accumulator is necessary to accumulate water supplies so that the pump does not start working every time the water tap is opened. Automation, in turn, regulates the operation of the pump and activates it only when the pressure drops. For the stable operation of the pumping station, it is necessary that you have an uninterrupted supply of electricity.

Complete with pumping stations, as we already know, pumps are supplied. They also differ in their design and are either vortex or centrifugal.

In vortex models, suction occurs due to the operation of the blades inside the housing. The operation of such devices is almost silent, but they only lift water from a shallow depth. If you buy such a model, then you better install it directly in the house, as it is very sensitive to temperature changes.

Centrifugal models have a high level of noise during operation.But such devices carry out the rise of water from a great depth. In addition, such devices are insensitive to temperature changes. You can install a centrifugal apparatus in a special room near your home.

Apartment pump

For apartments, almost any model from the list above is suitable. A good option would be Grundfos products. In this case, it is worth choosing a pumping station if you live on the upper floors of an apartment building.

Pumps for apartments differ in the types of control. There are only 2 types, automatic and manual. With manual control, you will need to constantly monitor the operation of the device and adjust it. In the case of automatic control, a special sensor monitors the operation of the device.

To make the device work longer, you should additionally install a mechanical filter. Thus, you will protect it from foreign particles. It is best to install the pump in an apartment in a dry and heated place. In this case, it will work stably.

Following these recommendations, it will not be difficult for you to choose and buy your favorite model. Do not forget to also pre-watch reviews on the Internet for certain models to find out about interesting nuances. Happy shopping!

What allows you to increase the pressure in the system

In order for the pressure in the plumbing system to be higher, you must first deal with the reasons that caused such troubles. The root of the problem may be:

• leaks and breaks in pipes on the highway;
• reduction in the cross section of the pipeline as a result of the layering of calcium salts;
• filling the coarse filter;
• counter jamming;
• breakage of shut-off valves or check valves.

An example of clogged old pipes

In case of poor water pressure, first of all, you need to contact the neighbors living on the same floor. If everything is fine with them, then you need to look for the problem at home. Additionally, if the system allows, it is possible to partially dismantle the water main at the entrance to the apartment, having previously blocked the shut-off valves. This will help you gauge the pressure. In this case, you will need to substitute a bucket or basin so as not to flood the floors. The absence of pressure even at the inlet eliminates the need to maintain its part of the water supply. Then it remains to contact the emergency service so that they take measures to repair the water conduit, or embed a pump that increases the pressure.

When the problem is caused by causes within the apartment, the following actions will help:

• filter cleaning;
• washing aerators on mixer spouts;
• change of mixer cartridges;
• installation of new flexible hoses on taps and toilet bowl;
• reinstallation of the check valve;
• replacement of the counter if it is jammed;
• complete replacement of the wiring of old pipes coming from the riser to the points of consumption of the apartment.

Some Helpful Tips

Not always a booster pump is needed to solve the problem with low water pressure in the system. To begin with, it does not hurt to diagnose the condition of the water pipes. Their cleaning or complete replacement can restore normal pressure without additional equipment.
