Hot water filter: is it needed?

There is hardly a person who has never heard of the possibility of cleaning cold running water at home using a stationary filter. What about hot water? Today we will talk about how important the installation of a hot water treatment device is, not only to maintain human health, but also for the long-term preservation of the original appearance of the functional elements of its household appliances. The article will also discuss the main issues related to the classification of filters, the choice of a specific model, as well as their installation in your own apartment.

What it is

Devices for mechanical cleaning of hot water supply will “extend the life” of household appliances, faucets, and so on by “removing” substances from the liquid composition that destroy the integrity of the material of the plumbing, washing machine, or dishwasher. The principle of operation and the main purpose of the goods for filtering do not need additional consideration. However, before proceeding to a discussion of classifications and specific filter models, it is worth paying attention to the main differences between designs designed to clean products of cold and hot types of water supply.

The technology of "processing" hot water eliminates the possibility of the presence of a fine purification per se, familiar to the "cold" type, since boiling water itself is an "aggressive" starting material. Given this fact, the first difference between filters for modifying hot water becomes logical. Housing materials, as well as replaceable cartridges used in their manufacture, must be resistant to high temperatures and various kinds of mechanical damage. For such purposes, as a rule, they choose high-quality plastic or metal that can ensure complete isolation of the filtration process from external circumstances. It is important to keep in mind that, in spite of the possible “replaceability” of the cartridges of plants for “processing” cold water with those intended for hot water, the reverse replacement is impossible due to the insufficient strength of the materials used in the creation of filters for cold water.

No less important is the distinguishing feature of "hot" cleaning associated with the method of installing its system. This type of filter is traditionally installed according to the main principle, in other words, "embedded" directly into the pipe. Their main purpose is coarse primary cleaning from rust and other impurities that adversely affect the chemical composition of the liquid flowing from all pipes in the room. For purification of cold water, flowing structures are used that are unable to provide the whole apartment with clean water at a time, which is quite feasible in the first case described.

Types

Understanding the characteristic features of the production and installation of devices for the “processing” of hot water, we can address the issue of their classification by degree of purification and its possible methods.

Cartridge filters, implying the presence of a replaceable cleaning element in the structure, are in turn divided by the type of its production into:

• disposable filament (the main material for manufacturing is polypropylene filament or reinforced nylon capable of catching particles equal to one micron. The frequency of replacement of this cartridge is determined by the filter manufacturer and, as a rule, is indicated on the product packaging);
• reusable mesh (the only possible material for their production is a metal that can hold particles having an average value of from 10 to 100 microns).

The flushing form of the water change devices is considered a kind of refinement of mesh cartridge filters, due to the presence of a replaceable cleaning element. Improving the "predecessor" is a method of cleaning the cartridge. If in the first case it is necessary to remove it for this purpose, then in the washing filter it will be enough to open the corresponding valve, thereby changing the direction of the water flow. As a result of the change in flow, water, washing away the pollution formed in the filter, will rush into a special tank.

Filters equipped with an automatic cleaning system are considered as convenient and easy to care for them. The design of this type of device implies the presence of gearboxes and timers that control their degree of contamination and pressure drops in the pipes. For automatic cleaning of the mesh cartridge, the user needs to set the periodicity of this process on his own, based on the manufacturer's recommendations and the volume of regularly “passed” water through it. The installed gearbox, in turn, can unscheduledly start flushing the cartridge in the event of a sharp pressure jump in the pipe, indicating a significant accumulation of dirt.

Before installing the device on the water main, make sure that the flask attached to it is strong. It is extremely necessary to do this in order to avoid situations when not only it, but also the entire construction of the treatment device, can “fly out” of the pipe during a sharp jump in pressure. Then, turning off the water and choosing a good place that provides easy access to the filter in case of unforeseen situations, you can begin to "mount" the devices. Traditionally, apartments are supplied with two sewage pipes, which means there should also be two main structures. The final step is to process the joints of the pipe and filter with fum tape and sealant. It is imperative that you wait for time to “dry” the materials for processing the “seams” and make sure the joints are completely tight. Only after there are no doubts about the correct installation of the filter can water be turned on.

Summing up the above material, we can formulate the main features and characteristics that can be used as criteria for choosing a treatment device for the "treatment" of hot water.

1. The initial hardness of the water in the pipes. In accordance with this indicator, it is necessary to give preference to the model of the filter, which according to the characteristics declared by the manufacturer has the ability to soften the liquid, several times higher than the existing level of rigidity. Otherwise, a certain part of harmful salts will “leak” into the tap.
2. The daily volume of water used, calculated traditionally by multiplying the generally accepted level of "water consumption" (2.5-3.5 liters per day) by the number of residents in an apartment or house. The figure resulting from the multiplication of a given number of liters by three will be considered the minimum characteristic that a filter selected by the buyer should possess.
3. Documentation. Despite the sufficient evidence of this criterion, many neglect it, but in vain. The purchased treatment plant must have all confirming quality certificates, warranty cards from the manufacturer, and so on, which will ensure the buyer’s confidence in the authenticity of the product chosen by him and minimize the risk of detection of marriage during installation or operation.
