The first site is the first step in the home improvement process. The site is the first step after signing the home improvement contract. It is also the most important step in all subsequent steps. In simple terms, it is generally necessary to ensure that the three aspects lay the foundation for later work. 1, confirm the design of the house, such as where to clear the need for a row of pipes, where they need to do, be aware of. 2, to determine the direction of the water and electricity coal.
3, to determine the changes in the structure of the housing, these need to communicate well with the construction team and the designer, one to be aware of, and second, to lay a good foundation for future projects.
The second line of the second electric pipe line that we need to visit is before the hydropower line is sealed. This also depends on three aspects. 1. The capacity of the wire should not exceed 40% of the tube. This is also clearly specified in the 3.15 standard. Second, we must pay attention to the strong and weak electricity can not be put in the same tube, for example, computer network lines and wires can not be worn in the same tube, if this happens, it will not only affect the normal work of the computer, but also possible Trigger a security incident. 3, finally to see if there is a groove in the casing turning place, because if the groove is difficult to pass through the wire.
The entry of the third material into the decoration materials means that the decoration has entered the construction phase. This is the most closely linked with the decoration quality at this stage. Don't take it lightly. We all know that in the home improvement process, there are many disputes related to decorative materials, such as: shoddy construction contractors, the owner's material supply affects the construction progress and quality, etc., so the majority of the owners friends are in the renovation Materials must be accepted when entering the site. 
The pressure test of the 4th pipe pressure test pipe refers to the pressure measurement type of the pipe after the pipe is completed. If the water pipe has seepage phenomenon, it cannot go through this process. This test is very necessary, because only after doing a water pressure test to ensure that there will be no leakage in the future, will be assured of this part. 
The fifth to do the ceiling first to see if the fulcrum of the ceiling around the wall is solid. Determine whether the wood keel has been treated for fire and corrosion protection. Because the ceiling contains wires, electrical appliances, transformers, etc. In case of electric leakage, it will lead to burning, so you should see it clearly. 
The first part of the sixth gas installation is to check whether the gas leaks after the gas is installed. The second is to check that the location of the gas is not too close to the wire, otherwise an accidental spark may cause an explosion. Experience exchange decoration experience
A ballcock (also balltap or float valve) is a mechanism or machine for filling water tanks, such as those found in flush toilets, while avoiding overflow and (in the event of low water pressure) backflow. The modern ballcock was invented by José Antonio de Alzate y RamÃrez, a Mexican priest and scientist, who described the device in 1790 in the Gaceta de Literatura Méxicana.[1] It consists of a valve connected to a hollow sealed float by means of a lever, mounted near the top of the tank. The float is often ball-shaped, hence the name ballcock. The valve is connected to the incoming water supply, and is opened and closed by the lever which has the float mounted on the end. When the water level rises, the float rises with it; once it rises to a pre-set level, the mechanism forces the lever to close the valve and shut off the water flow. This is an example of negative feedback and of proportional control.
