What do you need to pay attention to when decorating water and electricity at home?

In fact, water and electricity are very important when our home is decorated! Hydropower design is different from decoration design. Hydropower design is firstly safe and practical, and secondly decorative effect. The principle of hydropower design is not to move or change easily; Black if you can, and no bright lines are allowed. Next, I will tell you in detail! ~ 1. Drainage engineering Water supply and drainage engineering includes pipe accessories, installation of various nozzles, angle valves, water supply fittings, indoor drainage engineering, etc. Basic requirements: 1. Before entering the site, the horizontal line must be measured to check whether the original water pipe is unblocked; 2. The original household power supply (meter capacity, incoming line size), telephone line and broadband information network can be adjusted; 3, on-site inspection of household appliances, lamps and switches, sanitary ware position is consistent with the drawings or whether there is any omission, if there is any discrepancy, should be adjusted according to the actual situation; 4. Unless otherwise specified in the design, the hot and cold water pipes are all made of steel-plastic pipes, with a unified head of 20mm and a charge of Ф16mm; Check whether the pipeline is unblocked before installation; 5. Don't arbitrarily change the nature and location of waste and sewage discharge such as drainage pipes, floor drains and toilets. (except in special circumstances) the drain pipe must have a trap to prevent odor from coming up; 6. All steel pipes are connected with threads and lined with hemp, thick paint or raw materials. The acceptance of the pipeline shall meet the requirements of Supercharging; = 0.6Mpa after 20 minutes of pressure stabilization, the internal pressure of the pipeline drops 100mm, and the appearance inspection, hand feeling and water flow experiment of different planes are > = 50 mm Whether the pipeline layout meets the design requirements is randomly checked for 3 times. 2. Whether the pipeline installation is fixed and loose. 3. The downpipe shall be unblocked and the water meter shall operate normally. 4. The pipeline is smooth, the connection is free of leakage, and the faucet and valve are flexible to open. 5. Water pipes should not be installed near the power supply. Steel tape measures the distance between water pipe and gas pipe. Pipeline installation is horizontal and vertical, and the slope meets the requirements. In time, randomly draw three horizontal dimensions with pipe wood. 7. The water pipes leading to the balcony must be fully checked with valves. 8. The pipeline pressure test is about 0.6Mpa for 20 minutes. The pressure drop in the pipe is less than 0.05Mpa. Full-inspection pressure pump pressure test electrical engineering 1. All kinds of electrical switches and distribution boxes must be installed with certificates. Comprehensive inspection of electrical test II. Before sealing the groove, test the wire. 3. Indoor wiring should be tested before trench laying. 4. Power cord, telephone line and TV line, it is forbidden to install the computer line in the same pipe before the steel tape is sealed. 5. Test the insulation resistance. Check the megger. 6. Check the appearance of the installation panel. 7. Check the height of the socket from the ground visually and measure it with a steel tape measure. 8. Check the distance between conductor, switch connector and gas pipeline (mm). 9. Don't use neutral wire and ground wire mud. The position of the leakage ground wire is fixed. And select 10, telephone line, network cable, TV line, speaker check multimeter and tester in the same color as specified. The first step of hydropower transformation is hydropower positioning, which is to determine the position of switch socket and waterway interface in the whole house according to your needs. The plumber should draw the direction line of the outlet pipe and the electric wire on the wall according to the faucet position of the switch socket, that is, arrange the lines well. Remember to ask your decoration team for the hydropower map. Ask the plumber to tell you the route clearly according to the chart. Don't be afraid of trouble. The plumber will certainly meet your requirements. If you don't sign after the hydropower transformation, the plumber won't want the money of the decoration team leader. After hydropower positioning, the next step is to make a trough. The grooves made by good beauticians are basically straight lines, and there are basically no bristles on the edges of the grooves. Note that before slotting, be sure to ask the plumber to mark all the water and electricity trends on the wall, and remember to compare them with the water and electricity diagram to see if they are consistent. There are several points to be noted about hydropower transformation: 1. It is best to indicate the brand of wire used in circuit transformation in the contract. 2, the switch of the whole house should be basically in the same horizontal position. 3. The sockets in the whole house should be in the same horizontal position as far as possible, except for special sockets such as air conditioners and refrigerators and those with special requirements. 4. The colors of phase line and zero line in circuit transformation should be the same in every room. If possible, it is best to indicate the colors of live wire, zero wire and control wire in the contract, and the protection wire is yellow-green. 5. It is best to use 3 wires with more than 4.0 strands for socket wires (including air-conditioned refrigerators) and 2 wires with more than 2.5 strands for lighting wires. 6. The bottom box is buried underground. If possible, you'd better buy the bottom box yourself. Please report the installation fee to the decoration team. 7. As for audio cable, if you are not a professional enthusiast, it is best not to install audio cable: the housing area in Shenzhen is basically around 100 square meter, and the living room area is generally not very large. Ordinary people really don't need to install sound effects in such an area. Air traffic control is also silver. Regarding the waterway reconstruction, I think it is necessary to say: regarding the boiling water, in terms of the weather in Shenzhen, do washbasins and kitchen sinks need boiling water? If you need hot water, just turn on the water heater. When decorating, I only sigh that it is so easy to make money and spend money! Finally, it should be noted that it is best to indicate in the contract that carpenters must enter the site after the completion of hydropower transformation. The advantage of this is that you don't have to pay attention to two things at the same time. Hydropower transformation is a very important expenditure in decoration, and it is also a large part of the profit of decoration company. Moreover, the hydropower transformation is very hidden. If carpenters enter the site at the same time, it will distract you from the hydropower transformation. When the waterway is rebuilt, pay attention to the cleanliness of the surrounding area. When signing a waterway reconstruction contract, it is best to indicate the materials used for waterway reconstruction. In addition, attention should be paid to the size of the original sewer in waterway reconstruction, and the pipes connected with the original sewer in the house should be matched with the original sewer. In the circuit transformation, attention should be paid to where the lamps in the whole house are installed in advance to determine the position of the switch socket, and at the same time, attention should be paid to the different prices of newly buried wires and replaced wires. It is best to buy a wireless doorbell when buying a doorbell. Note the following: 1. Usability: Whether the position of the switch panel is convenient to use and reasonable should be considered comprehensively. 2. Availability: hydropower home improvement projects account for a large proportion in the expense report, generally around 1/5 (basic decoration), so avoiding impractical wiring can save a lot of money. 3. Correctness of wiring: Try to shorten the wiring distance when connecting water and electricity. Reduce unnecessary waste. However, care should be taken to ensure that the wiring on the wall and the ground remains horizontal and vertical. When laying pipelines, bending should be minimized. When the length of the straight line section of the line exceeds 15m or there are more than three right-angle bends, an intermediate junction box shall be added. Ensure convenient and straight maintenance in the future. 4. Stability: the circuit wiring should be protected by PVC pipes, and there should be enough distance between strong and weak current to avoid affecting weak current signals. Indoor wiring of TV, telephone and network cable is not allowed to connect in series. 5. Safety: the water supply pipeline should be suppressed for experiment, and the drainage pipeline should be drained for leakage test. 6. Finally, there should be a wiring diagram or real photos of the water circuit for reference when installing other electrical appliances in the future to prevent damage. * The basic requirement must be to hold the electrician certificate issued by the competent department of the state to work at his post, and the operation and construction must be carried out in strict accordance with the relevant national electrician specifications and hydropower technical specifications. We must actively seek the opinions of the owner, patiently listen to the requirements of the owner, and determine the positions of power switches, water level gauges, hot and cold faucets, etc. Construction can only be started after the owner is satisfied, so as to avoid rework caused by poor communication. All the main materials and auxiliary materials in the circuit and waterway reconstruction adopt national certified products. Strong and weak current lines and waterways should be laid in the wall with a spacing of more than 500MM, and exposed threads should be bandaged during construction. After the water and electricity decoration is completed, the construction personnel shall draw the completion drawing of water and electricity transformation according to the actual location and submit it to the company for the record. * Code for electrician construction: The temporary electricity utilization on the construction site shall be equipped with complete plugs, switches, sockets and leakage protectors, and cables shall be used for temporary electricity utilization. The power cord is divided into three colors: red is the live wire, blue is the zero wire and yellow is the ground wire. All one-way sockets shall be connected with "left zero and right fire in the middle" or "zero fire". The power supply lines of sockets, kitchens, toilets and bathrooms in each room should use leakage protectors independently and must be connected with other power supply lines, and the zero line should not overlap with other lines. High-power electrical appliances such as air conditioners must be equipped with special power supply circuits. The air conditioner adopts 4M2 power supply line, the lighting line adopts 1.5~2.5M2 power supply line, and all power outlets shall adopt 2.5M2 power supply line. Other power supply loads refer to this standard. All wires entering the wall are buried with 20% PVC smoldering pipe sleeves, and connected with elbows, direct connectors and wiring connectors. There should be no connector at the bottom of the box, and the power cord should not be exposed on the ceiling or directly plastered into the wall with cement to ensure that the power cord can be pulled out or replaced. Under special circumstances, when the power conduit passes underground, special attention should be paid to the close connection with the underground casing, and elbows must be applied where there is no joint source line in and out of the underground. Before the ground is closed, the PVC casing must be protected and not damaged. When laying floor tiles, PVC sleeves should be completely covered with sand. When nailing the wooden floor, the power cord should be laid along the corner to prevent the power cord from being damaged by nails. The power cord shall be horizontal and vertical, and shall not be pulled obliquely, and avoid the installation position of wall mirrors, furniture racks, etc. to prevent damage by electric hammers and nails. When the power cord is buried underground, it should not be considered to keep a distance of more than 500MM from the electric heater, water tank, water pipe and weak current pipeline. The power supply tube should be fixed in the wall groove in advance, and the surface of the sleeve should be recessed into the wall 13MM or more (the depth of the groove on the wall is more than 33 mm). After the power cord connection is qualified, water the wall surface, and caulk with 1:2.5 cement mortar. The surface of caulking concrete shall be smooth and 2MM below the wall surface. The power box should be installed firmly, and the bottom of the panel should be flat and consistent with the wall. The power supply of air conditioner should be 16A= = hole socket, the socket with protective door should be the height that children can reach (below 1.5M), and the bathroom should be splash-proof socket, with the installation height not less than 1.3M, and away from water sources. In order to live comfortably and conveniently, the bedroom should be equipped with double control switches, and the kitchen power socket should be connected in parallel. There should be more strong and weak electrical outlets, and there should be power outlets and telephone outlets on both sides of the bed. There should be three power sockets near the computer desk in the living room and on the background wall of the TV cabinet, and corresponding sockets for TV, telephone, multimedia and broadband network should be set. The switch box is generally1.2m above the ground, and a multi-purpose socket is used in one room. The height of all sockets and switches from the ground shall be greater than 300MM, and the height of sockets in the same room shall be the same (height difference > 0.5MQ The telephone line connector must be a special connector * Code for Hydraulic Construction * When the hydraulic works enter the site, the water storage test must be carried out in the kitchen and bathroom first, and it is necessary to go downstairs to observe whether there is leakage after two days. If there is any leakage, the owner shall be notified in time for waterproof treatment. The direction and arrangement of double water supply pipes should be reasonable and should not be inclined or crossed. Waterway reconstruction adopts aluminum-plastic pipes and edge fittings. Before installation, water pipes and connecting fittings must be inspected for damage, sand holes and cracks. The installation position of water meter should be convenient for reading, and the distance between water meter and valve and wall should be appropriate for easy use and maintenance. In the wall and underground, use as little or no connectors as possible to reduce the hidden danger of leakage. Connectors should be installed firmly without leakage. The two reserved openings of the double water supply faucet should be at the same horizontal line and symmetrical with the axis of the basin and pool, and the central axis of the reserved opening plane is perpendicular to the wall surface. The height of the water inlet (elbow) on the wall should be appropriate, it should be easy to maintain, and the hose should be exposed as little as possible, and no extra hose should be connected, giving people a simple and beautiful vision. For sanitary wares classified by columns without cabinets below, the height of the reserved opening should generally be about 600MM on the ground. The lower outlet of the column basin should be located at the bottom center or behind the column, and cover the column as much as possible. The drain pipe of hanging-free washbasin (without column or cabinet) must be horizontally arranged with the elbow out of the wall (that is, the drain pipe enters the wall). Water supply pipes with cabinets, washbasins and vegetable basins should be led out from the wall and cabinet backboard with elbows, and the height should be about 300MM higher than the bottom of the cabinet (400MM from the ground), not from the bottom of the cabinet. The faucet is generally 1- 1.2 meters from the ground and 30-40 cm from the washbasin. After the pipeline connection is completed, the reserved elbow should be blocked in the wall groove by blocking the line, the water valve should be closed and the pressure test should be carried out. The pressure test pressure should be 0.8 MPa, and it is qualified if it is not reduced for 24 hours. At this time, you can seal the water pipe into the wall. The ambassador's launching should go directly into the main sewer pipe and must be equipped with an underwater pipe head to prevent odor. The floor drain must be placed at the lowest point of the ground. Cabinets and washbasin cabinets should avoid the sewer pipe being set at the edge of the cabinet door and the center of the cabinet body, and the gap between the sewer pipe and the bottom of the cabinet body should be sealed with latex water scraps. Finally, I will give you a friendly reminder! ~ After the installation of the drainage pipeline, a water flow test should be conducted to ensure the smooth underwater flow without leakage and overflow. There are some small details to pay attention to! ~ that's probably it! ~ I hope to help you! If you think my answer is good, you can give me a compliment! ~
