Every summer in any multifamily house for one-two weeks cut off hot water. And sometimes, and irrespective of season, for a period of up to two days disconnect also cold. For what it is done?
Instruction
1. Planned cutoff of hot water is carried out for the reason that the equipment of combined heat and power plant and boiler houses needs preventive maintenance. Boilers clean from scum, repair the worn-out equipment. It would seem, one-two weeks - the considerable term, but then the equipment smoothly work nearly a year more. If such service was not made, the equipment would bring unexpectedly, including among winter, what is much more unpleasant.
2. In countries of Western Europe in many houses other system is used. Small-sized boiler houses are located in basements, and serve only apartments of that house in which are established. Service of such boiler house takes only one day a year, but in terms of efficiency it is much less effective, than big combined heat and power plant.
3. Cutoff of cold water - the investigation of either emergency situation, or modernization of pipelines. The first happens slightly more often. In most cases accidents happen at sharp temperature drops of air. They are eliminated quickly - sometimes water supply is resumed in hour.
4. Sometimes water supply in all strut of entrance should be cut off because of carelessness of one of residents. For example, if he has gone to business trip, has forgotten to close the crane, and water fills in neighbors - not to break because of it door. If any of residents has accident in heating system, it is necessary to disconnect it.
5. At modernization the worn-out pipes, including, underground replace with others, made of modern materials. Sometimes old pipes at the same time do not remove, and stretch new in them. Replacement of pipes is carried out longer in comparison with accident elimination, but then it smoothly serves decades.
