Filters under the sink for water treatment: how to choose and install?

Modern filters under the sink are relevant and necessary devices serving one of the structural components general health maintenance system due to environmental degradation, and a corresponding reduction in the quality of drinking water.

typology filters

The consumer market quickly to respond to the ever-growing consumer demand for devices capable of converting water into a useful product, and at this time, many manufacturers offer a variety of designs and cleaners features:

• Filters - pitchers;
• flow filters, dress up on the crane.

These simplest constructions do not provide the full result and have low productivity. The growing popularity of the filter under the sink, having more than one degree of purification. A three-stage model provides a sufficiently high level of water purification and is widespread.

Key reasons for the filter installation

The quality of water, especially consumed directly for drinking or cooking, depending not only virtually all physiological processes in the body, but also efficiency, good mood, irritability and lack of fatigue. Eighteen liters per day of water present (no coffee, tea or fruit drinks) - is the need, therefore overriding requirement to it - purity of contaminants.

Unfortunately, this figure is far from perfect due to some reasons beyond the consumer:

• defective water treatment utilities;
• deterioration of water mains, corrosive processes, causing contamination of the water flows, even previously well cleaned, according to the consumer following way.

Standardization of replaceable cartridges in a filter structure can allow packaging depending on the starting performance. emphasis toward softener, excluding iron cleaner, or to strengthen the position sorption protection if desired.

Among the factors that motivate to select flow-through filter type, distinguished and important of its features:

• high speed and sufficient capacity for home use;
• ease of operation;
• long service life of cartridges;
• compact, allowing installation to completely hide in a niche.

Design features multi-stage systems

If you decide to choose a modern modification of the cleaning water filter, you should pay attention to its features and functionality. The design provides multiple filter modules for performing different tasks. Their number varies from one to five, allowing you to choose an option for the specific conditions.

Such modifications look modern and not create difficulties when using the crane. The entire kit modules, thanks to its compact size, can be easily installed in the lower section of a washing capacity and a separate top output tap for purified water, which allows the main valve to wash utensils.

Modules are plastic flasks with a replaceable cartridge having a different purpose.

1. Mechanical cleaning: detention of solids (rust, sand, silt) provides nonwoven propylene, leveling chlorine, organic compounds, salts of metals, particularly heavy hydrocarbons using carbon sorbents.

1. Water softening by ion-exchange resins used as fillers cartridges.

1. Removal of dissolved iron.

1. Integrated impact on detention of toxic substances, iron bacteria, heavy metals.

1. Improved filters under sink equipped reverse osmosis membranes, capable of retaining microscopic particles such as viruses. They should be selected with a serious approach to the problem of health savings. Among the cartridges have filters for mechanical pre-treatment, as well as analogs with a carbon filler. To saturate the distillate provided deodorizing cartridges and mineralizers. The tank accumulating a ready-to-eat pressurized moisture eliminates interruptions even in case of failure in the line.

1. Fitting become available, further equipped with sources of ultraviolet rays contributing to disinfection.

By purchasing a quality filter under the sink, you need to keep in mind that the package includes all due construction, cleaning elements - cartridges, connectors and fasteners, valves, allowing quickly to establish all system.

selection criteria

Advantageously, before acquiring the filter under the sink to establish what the composition of the water entering the building and from which harmful impurities should be cleaned. In this case, there is an opportunity to get expert advice and choose the items you want, taking into account the following causal pattern:

• high performance water hardness will be the most optimal measures for its mitigation;
• if a reddish hue and laboratory studies suggest excessive doses of iron, you need filters with cartridges, is the lack of leveling.

If it is impossible to obtain laboratory data, you can use test strips and test kits. The strips are focused on measurement in the home of priority indicators:

• rigidity;
• acidity;
• content of free chlorine.

There are indicators locally determining each of these parameters, and is integrated analogs capable of immediately give three values. They are easy to apply, it is sufficient to immerse themselves in a container with water and immediately pull out. In order to establish compliance with the control plate there.

At excessively high values ​​of hardness ion exchange cartridge only partially solve the problem. In such cases, you must put filter system with reverse osmosis.

It also optimally will be useful, if some households have kidney problems. Performance of the future treatment plant should be selected based on several factors:

• projected level of daily consumption, which is directly proportional to the number associated with a family member or a back office employees (resources cartridges are specified in the documentation);
• Receive recess located directly under the sink. It depends on the possible future size of the filter;
• experts recommend to focus on the domestic brands, which really take into account the features of the real state of water resources.

What you need to consider when installing the filter?

The filter is connected to a cold water supply through a flexible liner and above the upper plane at a separate opening displays local tap supplying clean water, which it is advisable to install the adapter and securely fix on countertop. Thanks to the sophisticated design and complete set Installation does not cause particular difficulties.

Among the proposed range of filters you can stay at the design with two terminals, one of them supplies water having passed thorough cleaning for cooking, and the second - are already saturated with minerals - for drinking.

Basic nuances of the installation depends on the characteristics of the water supply to the sink. Experts must take into account the need for easy future maintenance, allows you to change cartridges without problems.

For this reason, over the bulbs should be a clear space of not less than 15 cm. This takes into account the need to maintain free access to basic sanitary fittings.

Before beginning assembly operations overlaps the main water supply, and for better sealing joints wrapped tape. It is also necessary to establish all the details, that there was no twisting tubes. The closed facades are necessary, as the sun's rays should not fall on the filter surface.

The end of the installation work is considered to hold a controlling start-up of water, which allows to determine the presence or absence of a leak. The first liters it is advisable to drain.

Correct operation

In the operation of the filters under the sink does not pose special difficulties. It is only necessary to remember that the purity and quality of water will be provided, if timely replacement cartridges, using the instructions in the manufacturer to comply with the operational resources.

If the technical documents expiry date is given in liters consumed no water, and in particular the amount months or days, this should be taken into account and respected, as late cartridges do not use bring.

To replace overlaps water, the internal pressure in the system is reset. Removing the bulb, remove the cartridge. New cleaning parts placed in a pre-washed with soap, rinsed with pure water and dried flasks.
