Purpose and rules for installing a coarse filter. Coarse water filter: system installation, useful tips for cleaning and replacing Plastic coarse filter how to install correctly

Water flowing through pipes or from a well contains a variety of biological and chemical impurities, as well as mechanical pollution, which can be dangerous both for human health and for complex household appliances and expensive plumbing.

Helps remove large impurities main filter for coarse water purification.

It is installed directly at the entrance to the house. Also, such devices are also called pre-filters. They trap grains of sand, silt and other contaminants and prepare water for further purification by other filters.

Those who purchased expensive household appliances were probably warned that the manufacturer's warranty would only be valid if there was a filter at the inlet, that is, pre-cleaning is a prerequisite. Plumbing reacts to water quality, stains and plaque may appear, connections begin to leak, gaskets need to be replaced faster.

Even water meters can not withstand dirty water and fail.

If the house has a fine filter, then the pre-filter will facilitate its work, less often it will be necessary to replace the cartridges.

In city apartments, the installation of different main devices for both types of water is required. At the same time, the filter for cold water should never be used for cleaning hot water.

By the type of cartridges, the following types of devices are distinguished:

mesh,
corrugated,
winding filters.

The equipment can also differ in the degree of cleaning.

According to this indicator, there are:

single-stage - to remove rust, sand, sediment,
two-stage - additionally remove chlorine, clay, organic matter, unpleasant odors,
three-stage - make water softer, remove iron.

Before buying a main device, it is important to determine the following parameters:

line type (hot or cold water),
required level of purification (mesh or cartridge filters can be used),
body type (with high water flow - Big blue, with a small Slim Line),
the level of hydraulic losses (the higher your apartment, the less losses should be),
type of cartridge (selected after water analysis).

Rating of the best coarse water filters for home

Main filters Geyser- are used for cleaning and conditioning water for household needs. They perform a whole range of tasks - from the simplest to complete reverse osmosis treatment, as a result of which the water becomes completely drinkable.

The body can be made of plastic or stainless steel. A large selection of cartridges for water purification of any level of contamination is presented. Replacing equipment cartridges is quite simple, and the devices themselves are durable and reliable.

Another market leader is the company Aquaphor offers Viking models for installation in a city apartment or in the country. Effectively remove sand and rust, pesticides, heavy metals, unpleasant odors.

The strong metal case provides resistance to mechanical loadings and a high pressure.

Differs in high speed of cleaning — about 25 l/min. The compact design allows you to place equipment in inconvenient and hard-to-reach places.

The honeywell coarse water filter is deservedly considered one of the best, its advantages:

patented backwash mechanism,
no need for cleaning
increased reliability and durability.

Not afraid of pressure surges, easy to install and use.

The Israeli company Arkal produces equally high-quality coarse water flow filters than the previous manufacturer. Their products are not yet so popular in Russia, but they are very often used in European countries. The main cleaning element is polymer discs that are resistant to corrosion and pressure surges.

Installation instructions - how to unscrew the coarse water filter

At installation of a coarse water filter it is worth relying on the arrow pattern on the body, which shows the direction of water flow.

If filter cleaning is provided, a bypass line will be required.

In general, the procedure will be as follows:

Install the equipment with an adjustable wrench. For a perpendicular filter, the sump must be placed with a cover down to allow dirt to accumulate.
Flush the equipment by opening the drain cocks under the instrument.
After 30 seconds, you can return the device to its working position.

Do-it-yourself coarse water strainer cleaning

If you need to replace the device with a new one, follow these steps:

Turn off the water, leave all taps open to relieve pressure. Then close the taps back.
Twist the old filter with a wrench, remove the clamps from the wall.
Remove the old seal, wind a new insulating tape.
Attach the device to the wall.
Turn on the water, check for leaks.

Are there any differences in coarse water filters for a country house

Coarse water filters for summer cottages have a number of differences from similar equipment for use in urban apartments. First of all, the difference is due to the composition of water. In the city, water is characterized by increased hardness, and in the country, many are faced with the smell of hydrogen sulfide and the taste of metal.

Also, the selection of equipment is carried out taking into account the source of water intake, because the water outside the city does not undergo preliminary treatment and comes directly from a well or well.

In individual houses, it is possible to use a wider range of equipment, since usually there are no problems with free space for appliances. For this reason, many install more complex integrated systems of not only coarse, but also fine water purification.

Some manufacturers offer universal devices that can be used both in a private house and in an apartment. Before buying such a device, it is still recommended to analyze the water and understand whether it is suitable for water treatment in your area.

Water entering an apartment or a house from a well or water supply contains a lot of different substances: chemical, biological and mechanical.

Coarse filters are used to purify water from its largest fractions - mechanical impurities. Currently, such devices are placed at the entrance to an apartment or house, behind shut-off equipment, or in front of counters.

Consider the main types of coarse water filters for installation in front of the meter, their features and principle of operation.

Reticulate

It occurs most often, it is distinguished by long-term operation without replacing the working part, which in such installations is a grid with rather small cells - within 20-500 microns.

These devices can be divided into subspecies:

backwash filter(clogged cells are automatically cleared of debris, and the body does not need to be disassembled for this).
no flush filter(in other words, mud collectors, cleaning occurs only after complete disassembly).

According to the method of fastening, it can be threaded, flanged or coupling. According to the location of the sump - straight or oblique.

This product, designed for industrial or domestic cold water treatment, is equipped with a transparent housing for visual inspection of the condition of the grid. For hot water, the body has a metal design, as it tolerates high temperatures better.

Cartridge (cartridge)

In such a device, the filter material is replaceable cartridges that are placed in a flask body made of plastic or metal. They trap particles from 0.5 to 30 microns, and need periodic replacement of such cartridges.

Cartridge filters upstream of the water meter are used where the particles are very fine and cannot be retained by the mesh. They are usually installed on small streams. If the flow is stronger, the device will be larger in size and price.

A feature of this variety is that work items can be used to remove not only the mechanical fraction, but also impurities. So, using a cartridge impregnated with carbon, chlorine can be removed. The stocking-type model copes with the cleaning of viscous clay and mud with algae.

Principle of operation, what are they for?

Water in urban networks before being supplied to consumers, of course, undergoes various degrees of purification. But utility networks, along with water pipes, are almost always badly worn out, and the flow of water carries rust, scale, debris and lime deposits from pipes.

Household water purification devices for food solve the problem in a very one-sided way. Small particles have pronounced abrasive action, and, thanks to this, the seals of plumbing devices, household appliances, but most of all, wear out quickly.

The only way to get rid of this problem is to install a coarse filter. The principle of operation is the passage of water through a fine mesh or other structure in which suspended solids are trapped. After the water can be subjected to finer purification.

Given the quality and composition of the water coming from the tap, it is undesirable to eat it without preliminary purification. find out in the following article.

The right choice of cleaning system is a guarantee of the safety of the inhabitants of the cottage. Currently, manufacturers offer different filter options from,.

Connecting to the system

Installation of filters is subject to certain installation rules. If plumbing plastic, copper or stainless steel, then the filter is placed immediately after the valve, if it is old steel pipes, then the CSF is installed directly in front of the water meter. The availability of free space is taken into account, based on the size of the product, the possibility of maintenance and visual inspection.

First of all, a tap is made from the common “thread”, and a tap is installed in front of the device to turn off the water in case of disassembly and cleaning of the device. The filter is installed using an adjustable wrench. It is desirable to place a perpendicular filter with a sump down, it is better to place oblique filters vertically.

Be sure to match the direction of the water flow with the direction arrow on the device.

A sealing agent is wound around the thread and the water meter filter is screwed onto the pipe careful movements of the key.

Installing the device in front of the counter will be within the power of everyone, since this process is not time-consuming and not complicated. Much more important choose the right cleaning equipment. On this issue, it is wiser to seek advice from specialists, since the safety of meters and household appliances depends on the quality of the installation.

To perform preliminary purification of water supplied to residential, industrial and public premises, experts recommend placing purification filters at the inlet of the water supply network.

Although drinking water is purified and prepared in municipal treatment facilities in accordance with the standards of sanitary and epidemiological services, it then enters houses and apartments through an extensive pipeline network. Not always the condition of water pipes is satisfactory.

By supplementing the measuring equipment with special fittings, you will maintain the accuracy of water meters measurements and increase the service life of the devices. The filter is installed in front of the meters for additional purification of the water flow passing through the measuring device.

Basic provisions for installing "mud" filters

The most popular coarse cleaning devices are oblique mesh filters. These devices are versatile, easy to install and inexpensive.

The tank has a cylindrical mesh and a special plug. The water that enters the filter is cleaned of foreign particles larger than 15 microns. Such devices will protect not only the CPU, but also many other household appliances that use water in their work.

Filters with finer meshes that trap the smallest dirt particles can be installed on faucets or at the entrance to household appliances.

Installing a filter involves following several rules:

The filter is mounted directly after the shut-off valve - where the water supply enters the apartment;
The direction of the water in the pipe must correspond to the arrow shown on the device;
Filters are mounted on vertical pipes with water directed from top to bottom;
The device must be placed with the stopper down - it is also necessary to provide free space for convenient removal of the mesh.

Filters are selected according to the parameters of water communications - this information is always indicated on the device case and in the documents. The joints of the pipes are fixed with a special tape or tow. To check the reliability of fastening, you need to turn on the water for a short time - if there are no leaks, you can safely use the device.

How to clean the filter element

The filter should be cleaned depending on the contamination of the water. Experts recommend checking the condition of the sump at least annually, without waiting for the pressure to subside. When the filter connection is in an aggressive environment for too long, the cap sticks to the threads and becomes more difficult to remove.

Moscow Reconstruction provides customers with a full range of measuring equipment maintenance services, including filter cleaning. Remember that careless handling of the elements of the plumbing system, including shut-off valves, can lead to emergency situations.

The filter element is cleaned in the following order:

We block the water;
Carefully remove the cover from the slope with a wrench;
We take out the mesh and clean it with a stiff brush;
If there are defects on the grid, we change it to a new one;
We clean the reservoir chamber;
Install the grid in place;
Change the seal on the thread;
We twist the lid;
Turn on the water and check the reliability of the connections.

If the filtration device is included in the sealing circuit, the Management Company must be notified about the removal of the seal. After the cleaning is completed, the LCD staff restore the filling.

We make a number of well-founded complaints about the quality, chemical composition and purity of water supplied by the central water supply. They are justified by the deterioration of health, the rapid wear of equipment and the eternal problems with water pressure. Both our physical and economic condition deserve attention, don't you agree?

To combat the listed negative circumstances, there is a proven method - you need a coarse and fine filter. Depending on the tasks to be solved, both separate devices and a group of interconnected devices that perform multi-stage processing are mounted.

Here you will find out what kind of work a certain type of device performs, in what sequence they are arranged, how they ultimately affect the quality characteristics of water. For a full perception of the information, we have attached visual illustrations and video guides.

The first, most important step in water treatment is mechanical cleaning. Coarse cleaning devices extract particles from 1 micron and above from water. They perform an indispensable function in the filtration process, without which further water treatment is impossible.

Rust, sand, clay particles, scale from old water pipes - everything is removed to get clear water at the exit.

Everyone knows that water from the central plumbing system contains a large amount of impurities. In this case, we are talking about mechanical pollution, which contain particles of various sizes, chemicals of organic and inorganic origin, viruses, bacteria and other microorganisms. To solve the problem of contaminants in tap water, you can use a filter. However, the purchase of a product is not the most important step, it is necessary to properly install it on the pipes of the plumbing system.

Installation of a coarse filter

The coarse filter has another name - a mud collector. The fact is that such a device is designed to delay the largest particles of mechanical impurities. The design of coarse filters has several options, but the installation of all types is carried out according to the same scheme.

The main condition that must be observed when installing the device is the location of the filter immediately after entering the apartment or house. The second condition is installation before the meter, but after the locking fittings.

The installation process can not be called very complicated. The filter housing has a thread through which the device is screwed onto the pipe. To seal the threaded connection, a sealant can be wound around the pipe.

Installing a cartridge type filter

With the help of a coarse filter, it is possible to purify water from large mechanical impurities, but after that a large number of inclusions of a different nature remain in the water. In particular, we are talking about fine mechanical suspension and various dissolved substances. For further water purification, cartridge filtration devices are used. Such devices have a head part, which is fixed on a water pipe, and a glass into which a filter cartridge is inserted.

There are several types of filter media, each of which purifies water from contaminants of a certain origin. These can be carbon, adsorbing, ion-exchange fillers or allowing for finer purification from mechanical impurities (in more detail: "Fine water filter - types, purpose, selection rules").

The scheme for installing filters for water purification is the same in all cases and does not depend on the type of filler. In particular, the following actions are expected:

Before you install a water filter, you must determine its location. It is important to consider that the device should not interfere or be subjected to mechanical stress.
Next, choose the correct location height, here taking into account the need for regular replacement of the cartridge. Therefore, in order to freely remove the glass, you need to maintain a distance from the filter to the bottom surface of at least 10 cm. Knowing how to change the water filter, you can do it yourself.
Having chosen the best location option, proceed to install the water filter. First, turn off the water in the system and open the nearest faucet. Such actions will allow you to remove all the water that filled the pipes.
Then you need to cut a section of the pipe to install the filter device.
A valve is welded directly in front of the location of the filter, with the help of which the water supply to the filter will be limited.
Couplings are used to connect the head of the device; after installation, the joints are subjected to a thorough check. Additional sealing materials can be used to more tightly seal the joints.
The selected type of cartridge is released from the packaging and inserted into a glass, which is then fixed on the head of the device.
After installing the water filter, the system and the new device are tested. For this purpose, open the shut-off valve at the inlet of the water pipe to the house and the water intake valve. The water supply will reveal defects at the installation site of the cartridge filter.

Features of installing a water filter under the sink

The design of the filter for washing is more complex than the previous options; it contains several filter elements. Therefore, you need to know how to connect a water filter. It is not necessary to assemble the device before installation, and the installation itself consists in attaching some parts to the pipe and filter.

The process looks like this:

Perform the connection of the tap and the tee, check the tightness of the connection.
The resulting element is connected to a pipe for cold water.
Fix the filter on the wall, leaving a distance of at least 10 cm from the floor.
On the countertop there is a faucet for clean water.
Connect the water filter to the water supply.
Check the performance of the installed filter and the tightness of the connections.

reverse osmosis system

Using a reverse osmosis system allows you to get the most purified water at the outlet.

To crash into the pipe of the sewer system, a hole is made in it. To ensure a snug fit, the clamp screws are tightly tightened.

Another feature is the need to install a storage tank when connecting a water filter, which is required for the normal flow of the reverse osmosis filtration process. The storage tank collects purified water, which ensures an uninterrupted supply of water, despite the slow cleaning process through the membrane.

A hose from the filter is installed at the inlet to the tank, and a hose for supplying water to the tap is installed at the outlet of the tank. Also, a stopcock must be installed on the tank, which stops the water supply.

Starting the system after installing the water filter involves the following steps:

The tap on the tank is closed and water is supplied.
Next, open the faucet of clean water and wait for a while.
The incoming water is drained.
Then the faucet for clean water is blocked and the shut-off valve on the tank is opened. The incoming liquid should be poured out to flush the tank.
