Installation of fine water filter

Water for humans is the source of life. Human health depends on its quality: the cause of a large number of diseases is poor-quality water. Purification of water entering our homes is already an urgent need. For this purpose, various filters and filtration systems are produced. These include fine filters. Installing a fine water filter is required in each house / apartment.

Kinds

The main purpose of the installation of fine filters is to bring water from the water supply system to the parameters of drinking water. This need arose due to the fact that we are almost technically served in the houses under the guise of drinking water.

Thin after-treatment is carried out with the help of cartridges with sorption, membrane filler, as well as with ion exchange resins. Compressed activated carbon or aluminosilicate is used as a sorbent. These filters can be used both one by one and in the complex.

The integrated use of sorption cartridges and ion exchange resin cartridges is called multi-level ultra-fine cleaning. It consists of three steps:

• The first step is a sorption filter filled with aluminosilicate with a cell size of 5 microns. There is a cleaning of mechanical pollutants and some chemical compounds of chlorine.
• The second stage is a filter with ion exchange resins. At this stage, purification from pesticides, nitrates, chlorine takes place. The chemical composition of water is changing.
• The third stage is a sorption filter with compressed coal. There is a final purification of water from the remnants of harmful substances. The taste improves, the water softens.

As a result of this cleaning is obtained drinking water of good quality.

If we add a membrane filter, an ionizer and a mineralizer to a multilevel filtration system, we obtain reverse osmosis. This is a system of molecular purification of water. After this purification, the water is purified by 99%, and then enriched with the necessary trace elements. Today it is the best way to purify water. The disadvantage of this system is the need to maintain pressure in the water supply system from 3 to 3.5 atm. If there is no such pressure, then it is necessary to additionally install a pump.

Choosing an installation site

Depending on why you need purified water, choose the place to install the filter. Suppose you want to extend the life of your plumbing fixtures, washing machines or dishwashers, electric boilers for heating water. In this case, it is enough to install one flask with a sorption filter near the water metering unit.

If you need high-quality drinking water, then a group of filters is installed under the sink in the kitchen. For more effect, you can install filters in two places at once.

Assembly

How to install filters in selected locations? In order to install one filter near the water meter unit, you must do the following:

1. Shut off the water to the apartment. Discard any residue from the system by opening the mixer.
2. At the place of installation of the filter cut the pipe. The cutting method depends on the pipe material. The metal pipe can be cut with a grinder with a circle on the metal, and plastic, composite and metal-plastic - with special scissors.
3. Cut a piece of pipe equal to the length of the upper part of the filter bulb plus the size of the fittings.
4. At the ends of the pipe we mount the fittings. Which also depends on the material of the pipe (if metal, then you first need to cut the thread).
5. Insert the cartridge into the flask and connect both of its parts.
6. Fasten the assembled filter assembly to the wall through special holes.
7. Attach the outlet of the upper part of the flask on the cap nuts.
8. Open the water. It is better to do this smoothly to avoid water hammer. If after filling the flask and water entering the system at the joints there are no leaks, then everything is done correctly.

In the case of water at the joints should tighten this connection. If this does not help, then you will have to close the water, unscrew the connection, rewind and screw it back. After that, open the water and make sure that there is no leak anywhere.

If you decide to install a multi-level treatment or reverse osmosis, then the sequence of work will be somewhat different:

1. Shut off and reset the water.
2. At the edge of the sink or in the tabletop near it make a hole for the installation of the crane. It will be located to the right or left of the kitchen faucet.
3. Disconnect the flexible inlet at the place of its accession to the cold water pipe.
4. In its place we twist the adapter tee. In the tee mount crane to attach the filtering system hose.
5. We install a factory-assembled filter system under the sink. You can, of course, assemble such a structure yourself, but the factory is more convenient.
6. Attach all hoses in accordance with the assembly instructions.
7. Attach the supply hose to the crane.
8. On the upper part of the adapter tee we wind the flexible supply from the mixer.
9. The system is assembled, you can open the water. The absence of leaks - a sign of the correctness of the work.

When choosing a filter or filtering system, carefully read the instructions for them. That quality of cleaning did not worsen, cartridges should be changed periodically. Their lifespan depends on the amount of leaked water and the degree of its initial contamination.
