Almost nobody drinks water directly from the tap nowadays. Indeed, it may contain substances harmful to the human body and dirt. In most cases, people prefer to buy bottled water. Sometimes kitchens also simply install a special type of faucets, complete with filters. The water from such taps usually goes pretty clean, which saves on the purchase of a bottled product.
Types of faucets with filters
On sale such cranes appeared relatively recently. However, all faucets of this type on the market today have a rather convenient and reliable design. In addition, such plumbing fixtures look quite stylish and modern.
In our time, if you wish, you can buy a crane filter of one of two varieties:
- with two holes;
- with one hole spout.
In the first case, two channels are located in one barrel of the crane. In this case, one of them delivers ordinary water, the second - filtered. Such mixers are regulated with handles located on the base.
For cranes of the second type, one channel is provided. In this case, the handles simply open or close the flow of filtered or tap water.
In appearance, such taps can also vary. There are both classic round-shaped faucets of this type on the market, as well as more modern ones - square with right angles in a high-tech style.
Design Features
If you wish, today you can buy a crane filter, designed for both fine water purification and coarse. Devices of the first type are quite expensive. It is advisable to install such taps exactly when water is used for cooking or as drinking water. These devices are a combination of the actual fluid supply system and filter. Special cassettes are responsible for cleaning them.
To remove various kinds of mechanical particles from water, ordinary ball valves with coarse filters included in their design can be used. Such devices are very inexpensive. The devices of this variety are used most often in private homes. That is, where water is supplied to the building from an ordinary well or well.
The principle of operation of taps with fine cleaning
Such devices, in turn, can be:
- inflow;
- equipped with reverse osmosis system.
In the first case, the crane filter is installed using a very simple technology. Cleaning cartridges are mounted under the sink. Then they are connected by a system of tubes to centralized highways and a tap at the sink. Tap water passes through the filter housing and is supplied from a mixer purified from salt, chlorine, iron and microorganisms.
Reverse osmosis systems are also mounted under the sink. Their difference from simple filters is that in them water passes through several cartridges at once and is cleaned to a sterile state. Such systems are expensive.
The principle of operation of ball valves with a filter
Such devices, in turn, can be mesh, flanged, straight, oblique. Faucets with filters of this type are usually installed not near the sink, but on the water pipes at the entrance to the apartment or house. Strainers are one of the cheapest and most popular types of such devices. It is such devices that are installed in apartments and houses most often. A steel mesh with a mesh size of 50 to 400 microns is responsible for the water treatment in them.
Flange filters have a special settler in their design. Approximately in the same way, straight ball valves of rough cleaning are arranged. In such filters, the sump is large. Therefore, they remove dirt from the water very effectively. The oblique filters also have a sump. But it is located at a certain angle to the flow of water.
What materials can be made
Like a conventional mixer, a tap with a filter, of course, must be chosen correctly. When buying such a device, among other things, it is worth paying attention to the material from which it is made. The filter service life will also depend on this.
Such devices can be made in our time from:
- stainless steel or steel alloys;
- plastics
- ceramics;
- bronzes;
- brass;
- nickel.
The most common at the moment are taps with water filters steel and brass. Also sometimes in city apartments plastic devices of this type are used (rough cleaning). Such cranes are relatively short-lived. But at the same time they are inexpensive, easy to install and replace can be easily at any time.
The best faucets of this type are, of course, bronze. Replacing a filter tap of this variety will not have to do for many decades. But at the same time, mixers of this type are very expensive.
Pros of using fine filters
Installing a device of this type in your apartment or house nowadays is definitely worth it. In terms of taste and composition, the water passing through such a filter will, of course, differ from the same bottled one. However, cleaning of modern devices of this type usually gives a good one. In any case, the owners of the apartment, and especially when using a tap with a reverse osmosis filter, can be sure that the water does not contain any harmful impurities or pathogens.
Among the pluses of modern wastewater treatment plants for fine cleaning is, among other things, to include the fact that, if desired, they can be installed even with your own hands. Manufacturers of taps with filters provide fairly detailed instructions for their installation.
The installation of flow systems, and even more so reverse osmosis systems, is, of course, technologically quite complicated and requires high accuracy of work. If during installation an error is made, at best, the water will not be purified. At worst, the owners of the filter tap will simply flood the neighbors. But still, with a certain degree of accuracy, it is possible to install such a device in your kitchen.
Cons of application
Water apartment owners who installed a tap with fine cleaning, are guaranteed to drink clean. The disadvantages of such devices are practically nonexistent. The only thing is that mixers of this type, in comparison with conventional ones, have a rather complicated design. Therefore, they fail more often. That is, the repair of the tap-filter for water to the owners of the apartment may have to do from time to time. Also, the owners of such taps sometimes need to replace the filter elements themselves. And this, of course, is always extra time and money.
Kitchen taps with a reverse osmosis filter purify water as efficiently as possible. But such devices have, according to some apartment owners, certain disadvantages. Reverse osmosis systems remove almost everything from water. As a result, it becomes almost distilled. Water that has undergone such purification does not contain not only harmful, but also trace elements useful for the human body. Today, reverse osmosis systems are also available for sale, equipped with cartridges containing such substances. However, devices of this type are even more expensive than conventional ones.
Pros and cons of using coarse filters
The advantages of devices of this type include, of course, primarily the fact that they effectively purify water from mechanical particles. In private homes, such filters are installed almost mandatory. Without such a device, a boiler, boiler, and circulation pumps will quickly fail in a residential suburban building.
The downside of using filter taps of this kind can only be considered that they do not purify water from all kinds of salts, iron, and microorganisms. In private homes, in addition to such devices, it is often necessary to install softeners, disinfectants, etc.
