Flushing of cold supply systems and HWS
Cleaning of water systems
There is a large relationship between the quality of drinking water and the condition of the pipes. Pipes have a negative effect on water quality. A nationwide problem is the presence of rusty and polluted water pipes in water supply systems. The use of flushing of water systems as a good prophylactic against the occurrence of contamination is recommended. Replacing metal pipes with plastic ones does not cope with the situation radically. In addition, the cost of pipe replacing in the house is too high for many consumers.
The reason for the formation of contamination is not only connected with pipelines. Residents of private cottages and country houses, owners of large shopping and office centers and other establishments who use their own water sources (artesian wells) for water intake often complain about the lack of water quality. Although based on the results of the analyzes performed, the water parameters comply with acceptable standards.
In order to effectively get rid of contamination in water supply systems, as well as to achieve almost complete restoration of its capacity, without compromising integrity and without partial or complete disassembly, it is possible, if hydrodynamic or hydrochemical flushing is carried out, competently using special chemicals.
Advantages of hydraulic cleaning methods
The speed of achieving a positive result in combination with minimal inconvenience for consumers and residents is among the undoubted advantages inherent in the hydraulic methods cleaning of water supply systems. Just one cycle is enough to perform high-quality flushing of systems that provide hot and cold water supply, as well as heating equipment.
At the same time, all actions related to flushing can be performed during the whole year, without draining the system, which is especially important for heating systems.
It is important to bear in mind that for flushing of drinking water supply systems it is possible to use only chemical reagents permitted by sanitary-epidemiological authorities in the Russian Federation. This approach will ensure its absolute security. It is also necessary to take into account the danger of the negative effect of chemical reagents on the state of the equipment – taps, gaskets, mixers, etc. Therefore, the preparation of the solution should be trusted to specialists familiar with its concentration.
Today, when carrying out residential construction or overhauling an old foundation, plastic pipes are often used to install water supply systems. They have a smoother inner surface than metal. This is important for the prevention of the formation of various deposits that negatively affect the state of the water. But even in such systems, periodic flushing is needed to maintain its normal condition. If the systems are still composed of metal pipes, flushing should be annual (according to the state of the water). Thanks to regular water treatment, it is possible to cope with many problems: fouling of pipes and emergence of sediments. This contributes to the extension of the life of the systems and a significant improvement in the organoleptic parameters of water.
Flushing can be performed in several ways, and the choice of one of them corresponds to each specific case, the condition of the pipelines and the initial indicators of water. In order to determine its quality, it is necessary to transfer samples to the laboratory. A conclusion regarding water supply systems can be made by a specialist who examines them. Only a professional will be able to choose a rational method for flushing.
The most common and appropriate method of flushing is hydropneumatic method. When it is performed, the system is supplied with compressed air along with water under increased pressure. Under the influence of water flow, the sediments are destroyed and they are washed out into the sewage system. Also, they often use the hydromechanical method, using a special cleaning unit made of soft materials, for example, foam rubber.
