When I was young, I thought that growing up was a very distant thing. Every night I spent the night counting the stars thinking of myself growing up. I would turn my eyes into an old-fashioned eyebrow. Mirror; Upper secondary school began to enjoy the scenery of college, once graduated graduate student now graduated, crowded in the bustling crowd every day as my ordinary legal citizen; thinking about going to marry and have a child is a very Awkward things, but accidentally, now also want to buy a house to decorate and set up a family ... This is the world's affairs, nothing can stand the scrutiny of time, in the loading of a big mix for a few months, vowed not absolutely sure not The house was installed, but accidentally, my family started work.
Changing water to electricity is the first step in the renovation. As one of the most important hidden projects, regardless of the amount of engineering or construction costs, and directly affect the convenience of life, safety and comfort in the future, and can not be changed at will, it can not be ignored.

Before changing water and electricity, there should be a detailed argumentation and sober understanding of the water and electricity needs of their new homes. Do not tamper with the functional zoning, general layout, and the number and location of the electrical appliances. I think that at least the following aspects should be done:
1) A clear understanding of the original water and circuit of the new house, especially the circuit, should understand the power load of the house, the cross-section of the wire, the size of the meter, and the number of loops and sockets. In addition, before getting ready to stay, you should also ask the developer for an "electrical completion plan." It is advisable to use a branch circuit with a conductor with a cross-section of not less than 2.5 mm2; a high-power electrical appliance such as an air conditioner should have a separate circuit with a cross section of not less than 4 mm2;
2) As far as possible, the new house should be called to participate in the design of the participating members. Imagine that the house has been installed. Everyday water and electricity that people need to use should be arranged in a suitable location. Draw the faucet and socket location on the wall; and after a few days, Repeat, verify its reasonableness; time can also draw their own path; sockets not too much, but less inconvenient, the International Copper Association recommends reference to Hong Kong standards: four bedrooms each, living room every 2.5 square meters One set, each kitchen group of 1.2 square meters, air conditioners, exhaust fans, washing machines and other special outlets;
3) It is necessary to make detailed understanding and investigation of the materials used for upgrading water and electricity. Water and fire are ruthless and electricity is more dangerous. Safety is the first element. Even if you spend more money, you have to make high demands on materials. In particular, contractors and students must learn to identify the true and false qualities of various common wires and pipes. At the same time, we must have sufficient sense of advancement to leave as much space as possible for the purchase of high-tech home appliances in the future.
4) Choose to change the water to electricity construction team. A lot of decoration companies that the students choose can do, but he still thinks it is best to send this part of the work to a professional team. However, regardless of who does it, various qualification certificates must be checked. Otherwise, you must never enter the construction.
For these tasks, I spent almost a month. In particular, the design of various port locations and alignment methods is self-determined. When our family's workers came into the field, they detailedly explained the concept and arrangement of the cricket, and construction was almost uncontested. There are many professional teams near Tiantongyuan. They chose CJ to change electricity and JD to improve water. Until now, they believe that the choice of pipa is correct.
The material is my own choice. In the installation of large, Kunlun wire seems to be an inevitable choice to change electricity. However, due to the price increase of copper, the prices of wire in supermarkets have been soaring, and the vast majority of Kunlun lines on the market are inferior products.俺 俺 俺 俺 俺 海 海 海 海 海 俺 俺 俺 俺 俺 俺 海 俺 说 说 说 说 说 说 说 说 说 说 说 说 说 说 说 说. The requirements of the threading pipe Zhang Gong repeatedly said that the plutonium would not be repeated. The line was selected by the Wenchang line pipe. The inner wall was brighter and smoother. The resistance of pulling the wire was not great. The wall thickness was 1.5mm. I was nearly 90 kg and I would not stand up. Deformation, and thick and not brittle, curved into a 180-degree surface and there is no large cracks, absolutely meet the need for 俺, the most important thing is that the price is really cheap ... interested students can go to the market to scouring what; water pipe selection nothing It can be said that the PPR pipe will use Jinde. At least five or six billboards in Jinbei's building materials market sell Jinde's direct sales billboards. However, they believe that they can directly call the Shenyang Jinde Company. Say that there is a team of water changers who are responsible for their salesmen near Tiantongyuan in Beijing. They did not say anything. A phone call was made directly and the price was not too expensive.
The entire renovation process went smoothly. I just had a good two days to catch up with the weekend and I almost worked with the workers. All questions are resolved on the spot, and the workers have good suggestions and they are immediately demonstrated. My home is a brick-concrete structure, and most of the walls are concrete. This adds a lot of pressure to the slotting of the wall. Generally playing a cassette slot for nearly 10 minutes, very hard.
There are many issues that need attention during the transformation process. Referring to the recommendations of the forum heroes and professional hydroelectric companies, together with their own experiences, the summary is summarized as follows:
1) Whether it is wiring or installing switch sockets, it must be horizontal and vertical;
2) The depth of the slot must not be less than 4 cm;
3) The distance between strong and weak electricity is at least 30 centimeters and the best about 50 centimeters;
4) In the same line pipe, the number of wires passed is as small as possible, generally no more than 3 strands, and excessive wear is not conducive to maintenance;
5) Different signal lines must be worn separately; they cannot share the same line pipe;
6) The branch of cable TV should not exceed 3, and it is necessary to install more branches and install signal amplifiers;
7) Must not slot the floor slabs;
8) Do not wear beams for line laying;
9) Do not place switch on the column;
10) There should be a 0.2-0.3 meter margin at the outlet of the outlet;
11) When the wire is out of the pipe mouth or slot, it must be protected to avoid damage to the wire.
12) Pay attention to protect the insulation layer;
13) If you can walk the open line, do not walk the dark line. If you can walk the top, do not leave the ground.
14) Keep as much as possible the cassette left by the developer. It is not possible to affix a whiteboard and not to seal it.
15) The transverse groove cannot exceed 30cm;
16) The wires in the tube cannot have connectors.
The changes in my family are very substantial. To be honest, I cannot meet all the above requirements. However, even if there was a violation, it was carefully decided after repeated measurement.
It is recommended that we carry out hydropower reforms together. My family is working together. There are real difficulties, first change simple, and then do complex. The waterway reconstruction was completed a little more than a day later. When the workers left the factory, they had to take away the original pipes that my family had saw and were rejected by me. However, the workers were clean and clean. I am very satisfied with this. The circuit modification workload is relatively large. It took a total of four days to complete the circuit, but the livelihoods are still quite correct.
After the completion of all, we must pay attention to strict acceptance. There are many similarities in hydropower, and we must strictly control security, rationality, functionality, and aesthetics. For waterways, pressure tests are also required. My home was pressed for eight and a half hours, but it was completely satisfactory. For the circuit, according to Di Kang’s argument, a full-load test (estimated after completion of home improvement) and a short-circuit and creepage test were performed. I strictly scrutinized all the lines and paid only when satisfied.
We must also pay attention to the measurement, carefully calculate the length of repeat, while at the same time for the brick structure of the groove or concrete structure slot; bearing wall punching or non-load-bearing wall to achieve the bottom, because the price difference. In general, the cost of water and electricity for contracted materials and materials is at least half and half of the cost of the hydropower reform. Therefore, boldly bargaining, do not have the slightest hesitation. My home was changed to electricity, with over 3,000 discounted expenses. At last I was cut off more than 300 pieces. Oh, it didn't take much effort.
Remind everyone that regardless of water or electricity, no matter whether it is bright or dark, it must be delivered to the final engineering drawings. This is very important; because only in this way, after a few decades, when your grandson will one day set a nail on the wall to play, you will not be nervous and sweat.
Having said so much, most of it is nonsense. The recent renovation began, Bao Qinggong had to run to buy anything. His wife jokes about daytime doctors and night contractors. In fact, this is quite accurate. Pull down a lot of assignments and slowly make up for it. Anyway, no one is eager to see it. This article is rushing to write, because we must let everyone remember: hydropower reform, safety first.
