Boiler - is that safe?
To define and secure boilers safely, some professional specialized organizations such as the American Society of Mechanical Engineers (ASME) develop standards and regulation codes. For instance, the ASME Boiler and Pressure Vessel Code is a standard providing a wide range of rules and directives to ensure compliance of the boilers and other pressure vessels with safety, security and design standards.5
Historically, boilers were a source of many serious injuries and property destruction due to poorly understood engineering principles. Thin and brittle metal shells can rupture, while poorly welded or riveted seams could open up, leading to a violent eruption of the pressurized steam. When water is converted to steam it expands to over 1,000 times its original volume and travels down steam pipes at over 100 kilometres per hour. Because of this, steam is a great way of moving energy and heat around a site from a central boiler house to where it is needed, but without the right boiler feed water treatment, a steam-raising plant will suffer from scale formation and corrosion. At best, this increases energy costs and can lead to poor quality steam, reduced efficiency, shorter plant life and unreliable operation. At worst, it can lead to catastrophic failure and loss of life. Collapsed or dislodged boiler tubes can also spray scalding-hot steam and smoke out of the air intake and firing chute, injuring the firemen who load the coal into the fire chamber. Extremely large boilers providing hundreds of horsepower to operate factories can potentially demolish entire buildings.
A boiler that has a loss of feed water and is permitted to boil dry can be extremely dangerous. If feed water is then sent into the empty boiler, the small cascade of incoming water instantly boils on contact with the superheated metal shell and leads to a violent explosion that cannot be controlled even by safety steam valves. Draining of the boiler can also happen if a leak occurs in the steam supply lines that is larger than the make-up water supply could replace. The Hartford Loop was invented in 1919 by the Hartford Steam Boiler and Insurance Company as a method to help prevent this condition from occurring, and thereby reduce their insurance claims

Plumbing work done in built home
During the construction of the house you need to perform a variety of hydraulic works. The most important is to create a home network, water and sewage, and then connect it to the next sanitation. The currently built homes are usually showers or baths with unusual shapes, as well as the sink and the same trays or bidets. In a separate room is mounted toilet bowl and sink, which must also be connected to the mains water and sewage. Well connected to the entire system must also be placed on the bathroom floor of the house. Before putting a home network plumbing to use it is still well tested by plumbers who want to home owners have not had any problems with it.
Reasons for leakage of water from the washing machine
Connecting the machine is connected with the provision of its good water drainage. As a result, our clothes are cleaned properly and we will not have to contend with the problem of leakage of water from the washing machine. One of the causes of such leakage is, in fact, not connected to the drain hose of the washing machine water from it. So it is good that we are not trying to connect the machine alone, but ordered professional to best plumber who turns on the occasion of our washing machine for the first time and check if it was really well connected. It is also important that the water valve mounted on the washing machine was not sure and did not allow for the fact that the water starts to pour into the machine, although it was not by us on.
