checking water meters
Plumbers employed by the cooperative to perform a variety of hydraulic works. These include repairs done in individual apartments on request of their owners and renovations carried out throughout the block. Usually in all apartments at the same time they are installed new water meters, corresponding to accepted standards. Plumbers make the readings of the counters and check whether they function correctly and that none of the residents of the block is not he cheat on by their counter just to get lower bills for water consumption. They deal with the replacement of defective meters with new ones, if you notice the occurrence of any irregularities in their operation.
There is water in the apartment
Water leak, which occurred in an apartment is doubly dangerous because it can cause flooding of the neighbors who live one floor below. Therefore, if we find the growing leak in the kitchen or bathroom, you should immediately call an ambulance, hydraulic, which would come at us very quickly. There will not be a problem closing the water in the apartment allowing for minimizing the existing flooding tiles and floors. Sometimes it may also be that in order to perform repair work you will need to close the main water valve in the existing block. To carry out such an act will have to have the consent of the cooperative, since closing the main valve will cause a break in the supply of water to all tenants.
Worth to know - water heating
Circulating hot water can be used for central heating. Sometimes these systems are called hydronic heating systems.15
Common components of a central heating system using water-circulation include:
A supply of fuel, electric power or district heating supply lines
A Boiler (or a heat exchanger for district heating) which heats water in the system
Pump to circulate the water
Radiators which are wall-mounted panels through which the heated water passes in order to release heat into rooms.
The circulating water systems use a closed loop; the same water is heated and then reheated. A sealed system provides a form of central heating in which the water used for heating circulates independently of the building's normal water supply.
Heating systems in the United Kingdom and in other parts of Europe commonly combine the needs of space heating with domestic hot-water heating. These systems occur less commonly in the USA. In this case, the heated water in a sealed system flows through a heat exchanger in a hot-water tank or hot-water cylinder where it heats water from the regular potable water supply for use at hot-water taps or appliances such as washing machines or dishwashers.
