Water filter housings: types of designs

The state of human health directly depends on the quality of water. Since the condition of water pipes in modern cities leaves much to be desired, every home should have a filter to clean the liquid. This design allows you to quickly and effectively remove harmful impurities, as well as enrich water with minerals. One of the main components of the water purifier is the housing in which the replaceable cartridge is located. Such an element has its own characteristics and characteristics.

Standard flasks for water purification filters are created from several elements.

• Cap with 2 threaded fittings. It is necessary to connect the filter to the pipeline system.In the inner part of the tip there are special channels that are necessary to separate the incoming and outgoing water streams. On top of the case there are through holes for fixing the screw brackets. Below is the internal connection with thread.
• Flask under the filter for cleaning fluid. Its elements and cap connect by using a thread from the outside. At the bottom of the flask on the inside there is an annular ledge. It is necessary to ensure the most dense connection of the element with a hole at the outlet. Also using this detail eliminates the mixing of different streams between themselves.
• Ring seal Most often it is silicone or rubber. Such an element is mounted to ensure the reliability of the butt threaded connection during the assembly of the filter construction.

Some models of filters incorporate a special button, which is necessary for pressure control. It is used when replacing the old cartridge with a new one. Also included with the filter is a corresponding key designed for assembling a node during installation or repair of a water purifier, as well as a special bracket for mounting the structure on a vertical surface.This element can be in the form of an independent tool or act as an additional detail on the top of the bulb.

The direct purpose of the flask is to ensure the operation of the cartridge in the water filter, since it is in it that the replaceable cassettes are placed (they first receive the liquid and then come out of it).

The process of functioning of the structure can be divided into 3 consecutive stages:

• the ingress of liquid into the flask on the external surface of the cartridge, which separates the structure from the inside into 2 sections;
• moving the purified water inside the flask after treatment in the filter element;
• the direction of the purified liquid to the nozzle for removal, as well as the pipeline from the filter.

Flasks for water purifiers are divided into several types (depending on the specific parameters). In particular, they can be classified according to the following characteristics.

• According to the material of manufacture. It can be all sorts of plastic options that let or not pass light, as well as stainless steel (stainless steel). The flask can be transparent.This option is optimal because it is possible to control the processes in the structure.

• Characteristics of the configuration tip. An additional button for adjusting the pressure level or a special bracket may be provided.
• To destination. Flask for water purifier is adapted for hot or cold water. Depending on this, materials that are resistant to high or low temperatures and expansion are used.
• Dimensions. Most often, the flasks have standard sizes that are suitable for many types of cartridges. However, it is better to select such parts for a specific filter model.
• At cost. On the modern market there are a large number of filter flasks, the cost of which can range from 500 to 9 thousand rubles.

The process of selecting the appropriate housing for the filter is not particularly difficult, especially considering that in modern stores there are many models with a detailed description.

However, there are still some parameters that you should pay attention to when buying a filter:

• Purpose If you plan to clean drinking cold water, then you should purchase the appropriate type of filter. Since flasks for hot water, for example, for use with a washing machine and a drain have other characteristics and performance class.
• Equipment. Before purchasing, be sure to check if a sealing ring and a key of the appropriate size are included. This will help to avoid inconvenience and waste of time during the installation process.
• External characteristics. These include dimensions, on which it depends whether the filter fits into your space, as well as the material of the flask (metal, with glass elements, using fiberglass and others).

Also do not forget about the cost. Often, this parameter becomes decisive when choosing one or another filter. If you want to save a little, you should be extremely careful and cautious - not always cheaper models are able to become good analogues of expensive designs.

Since the process of installing a filter flask is not too complicated, many people prefer to do it themselves, rather than invite professionals to do this.

Installation design consists of the following steps.

• Remove the old flask if you re-install the cartridge housing.
• Replace unsuitable or too tight sealing bands with new ones.
• Using the key, fasten the case to the stop.
• Check the tightness of the connections. To do this, you need to open the minimum flow of water, and then carefully see if there is a leak in the system.
• Eliminate design flaws, if any. So, when leaks should tighten the place of the backfill connection even more.
• If this method did not lead to the desired result, it is necessary to completely unscrew the flask and check the location of the sealing gum. It must not be twisted or deformed.
