[Renovation school] household water installation precautions and anti-cheat Raiders

The installation of water and electricity in modern home improvement is an important step. This has a very important connection with the use of electrical appliances and sockets, and the installation of sanitary ware and gas appliances. Therefore, we must fully consider the layout of the future and do a good job in the planning and positioning of hydropower. , What are the hydropower positioning precautions? Here we introduce: household water installation precautions and deception tricks.

Household Hydropower Installation Notes:

First, electrical installation

Lighting installation:

(1) When the weight of the luminaire is more than 3kg, it is fixed on the bolt or the embedded hook.

(2) Soft-wire chandelier, when the lamp is 0.5kg or less, the soft-wire self-suspension is adopted; the luminaire larger than 0.5kg adopts the hanging chain, and the soft-wire is forked in the hanging chain, so that the electric wire is not subjected to force.

(3) The light fixture is firm and reliable, and no wooden wedge is used. There are no less than two screws or bolts for each fixture. The rest refers to "Code for Construction and Acceptance of Electrical Lighting Installations for Electrical Installations".

Power switch, socket installation

(1) Mount the socket horizontally, face the right pole of the socket, connect the neutral line to the left pole, and connect the neutral line to the left pole.

(2) Wiring: Leave the wires thrown out of the box for maintenance length (15-20CM) to cut off the insulation layer, taking care not to injure the wire core, such as the switch, the inside of the socket as the terminal, and coil the wire in the clockwise direction. On the corresponding terminal of the switch and socket, tighten the pressure head. If the switch or socket is a plug terminal, insert the core back into the round hole terminal (when the hole is allowed to press the double wire), and then press it with the top wire. Note that the core should not be exposed.

(3) The installation height of the socket shall comply with the design requirements. When the design is not specified, the following requirements shall be met: The socket for concealed installation shall not be less than 0.3 meters from the ground, and the concealed socket in special places shall not be less than 0.15 meters. Safe outlets should be used in children's activities. When using an ordinary socket, its installation height should not be less than 1.8 meters.

(4) Special attention: In order to avoid AC power interference to the TV signal, there should be a distance of 0.5m or more between the TV feedline tube, socket and the AC power line tube and socket (in special cases, the signal cable is shielded. The spacing must not be less than 0.3m).

(5) In damp places such as bathroom and kitchen, waterproof and moisture proof sockets with good sealing should be used.

(6) The same type of parallel installation and the same installation height of the same indoor switch, and the control of a good order. The sockets installed side by side are not less than 20 mm apart from each other.

Weak twisted pair 568B standard wiring method: 1-white orange, 2-orange, 3-white-green, 4-blue, 5-white-blue, 6-green, 7-white brown, 8-brown.

Second, water installation sanitary ware manufacturers are responsible for the installation of the best by the manufacturer to provide good quality hoses and valves

The toilet shall be fixed with expansion screws and shall not be solid sealed with cement mortar. The base shall be flush with the ground and sealed with oil lime or silicone.

The drain pipe of the hand-washing (vegetable) basin and the washing tank shall have a trap, and the drain pipe and the ground water outlet shall be sealed without leakage. Hydroelectric reform is a systematic project. Netizens need to combine the knowledge of hydropower design, construction, and acceptance in the implementation process.

Hydropower decoration construction anti-cheat Raiders:

The reconstruction of waterways is the most important aspect of home decoration. Just like the nerves and blood of human beings, it gives life to the house. Therefore, it is not only necessary to think about the orientation of the outlets of wash basins, toilets, and washing machines before installing the water pipes, but also to choose the water supply pipes together. data.

Pipe laying:

Home decoration laying pipes from the ground top, many heads of households and construction teams in order to save information and shorten the construction period will be selected on the ground to spread water pipes, despite saving the data and construction difficulties, but not conducive to future pipeline repairs, and laying in the ground Water pipes are simply damaged.

Waterway construction:

To ensure the safety of waterway construction, it is necessary to use standard qualified water pipes and pipe fittings, and strictly follow the construction standards. After all the waterway construction is over, it is necessary to suppress the test. The laying of the best time from the top or the wall line, the amount of pipe may be added slightly, but it is conducive to future pipeline repairs.

Hydroelectric reforming device:

If the conditions permit, the construction of the substandard and non-standard project shall be removed from the first modification of the device; the repressive test shall be strictly performed to suppress the test. The experimental pressure of metal and its composite pipe is 0.6MPa, and it is regulated for 10 minutes. The pressure drop in the pipe should be no more than 0.02MPa and no leakage. The experimental pressure of plastic pipe is 0.8MPa, and the pressure is 20 minutes. The pressure drop in the pipe should be no more than 0.05MPa. leakage.

The use of standard qualified water pipes and pipe fittings requires the use of standard qualified water pipes and pipe fittings, and strictly follows the construction standards. After all the waterway construction is completed, it is necessary to suppress the test and no leakage is allowed. The position of the valve and faucet device should be in accordance with the rules, and the use of active facilities is convenient, the outlet of the water can be unblocked, and the water meter can work normally.

Hydroelectric construction crackdown test:

If the conditions permit, the construction of unqualified and non-standard projects will be removed from the beginning of the transformation of equipment to strictly implement the repressive test standards for repression tests. Under the premise of satisfactory application, valves, water meters, etc. may be placed in relatively shady positions or appropriately decorated.

House wire color:

All the cables in the same house are inconsistent in color. With the same line, the colors are inconsistent. In the future, the nature of the cable cannot be resolved and it cannot be repaired.

Electrical Engineering Construction Standards:

Strictly comply with the electrical engineering construction standards, the phase (fire) line should be consistent, the zero line should be a blue line, and the ground line must be a yellow-green two-color line.

socket:

The protective grounding measures for the connection of the socket and the orientation of the connecting conductors of the phase line and the neutral line are necessary to comply with the relevant provisions of the construction inspection standards. The leakage switch used in the socket should be reliable. Strong and weak electricity / switch socket device position to be accurate, pay attention to view the power status.

Wire colors consistent with the bottom box rules:

The same color in the same house is not the same, the bottom box is not the rule. The strong and weak wire head in the bottom box is not saved 15-20cm long, strong and weak wires are not sharing the thread, otherwise the strong and weak electricity will affect each other, TV, telephone computer audio is not a dedicated line.

Check strong and weak sharing:

Check whether the sharing of strong and weak electricity is not a bit. Whether the line goes through the corners of the pipe is to bend the arc naturally.

Demolition of the hydropower construction project from scratch:

If conditions permit, remove the equipment from scratch for unqualified and non-standard construction projects. The head of the household is required to be present at the time of the hydropower survey, and the problem is immediately determined to allow the construction to be rectified and tested from scratch.

Editor's summary: Household water and electricity installation precautions and anti-cheat Raiders are introduced here, I hope to help you, more information, please pay attention to this site.
