Precautions for installation of water and electricity, precautions for water and electricity install

1.Horizontal and vertical.

Hydropower decoration pays attention to horizontal and vertical, which is not only beautiful and beautiful, but also ensures the quality of the circuit through the same pipeline fixation with the same spacing, and will not be touched off the pipeline because of the subsequent construction links, and the later leveling and plastering tiles can be in contact with a large area to prevent the later stage from falling off, so the method of hydropower laying must be horizontal and vertical two points and a line, and the wall pipeline goes in a vertical line to avoid transverse slotting, otherwise the load-bearing wall will be damaged.

2.There should be a lock between the conduit and the wire box.

During construction, the wire pipe can not be directly inserted into the wire box, let alone flow out of a section, so that the wire can be inserted into the wire box, which is standard. The insertion of the conduit into the wire box is not conducive to wiring; If the wire pipe is too short and the wire box is not inserted, the cement will fix the wire in the later stage.

3.Keep a distance between strong and weak electricity.

In order to avoid the influence of strong current on the signal of weak current, it is recommended to keep more than 50cm between strong current and weak current when wiring.

4.The angle of the corner of the conduit.

In order to facilitate the later stringing and maintenance, there should be an angular arc at the turning place. At the same time, it should be noted that there cannot be more than 2 turns in a single line.

5.Pay attention to the number of threads threaded in the conduit.

In the national standard, the cross-sectional area of the wire in the line pipe can not exceed 40% of the cross-sectional area in the line pipe, and now many families use 4 points and 6 pipes, such as 6 points of line pipes, and generally the threading can not be more than 5.

6.Reserved wires in the kitchen and bathroom.

The top surface of the kitchen and bathroom should be installed with chandeliers and bath bomb lamps, and there need to be reserved wire connectors, so the reserved wires should be well protected, and hoses should be used to protect them to avoid damage.

Now many friends are decorating their homes.

As well as the requirements for hydropower settings are relatively high. In particular, the requirements for water and electricity decoration are even higher. The role of water and electricity in the home is like a blood vessel on the person, if the blood vessel of the person is broken, then it will lead to very serious problems, so the same is true of the water and electricity at home, once the water and electricity problems at home not only affect our lives, but also cause a very big hidden danger to our safety.

If you want to decorate the water and electricity at home or rearrange the wiring from the new, you must pay attention to it. Otherwise, the harm is very great.

1.Bridal chamber.

Secondly, the flexibility of the circuit is also a key factor. Be aware of the electrical plugs.

Centralizing a power strip on a power strip has an absolute better effect than a full wall of outlets.

Good. 2.Sockets and grounds.

The distance is usually 30 cm, and the minimum should not be less than 20 cm. If installed a low cabinet or tatami mats.

then the distance from the ground can be appropriately increased. At the same time, keep a little distance between the low cabinet and the wall, otherwise it is likely to block the socket. Secondly, the switch.

The optimal distance from the ground is 130 cm.

Then the wires. Must be a standard 4 mm².

1.Some renovation teams will deceive the owners in some links, and the suppression test is one of them. If the owner is on site to supervise at the time of suppression, then you can observe whether there is a circuit in the "return valve" of the pressure pump.

It is not available in the laundry area. If it is installed in the shower room.

Inside, because the amount of water is relatively small, the deep water floor drain can basically meet the needs. But the washing machine.

The drainage speed is very fast and the drainage volume is also very large, while the deep water drain is relatively slow, so it is likely to cause the water to overflow.

3.Hot and cold water pipes.

The installation requires special attention to the following:

1) The spacing between water pipes should reach 15 cm. The distribution faucet of an electric water heater.

The spacing between the upper water is 15 cm, and the individual is 10 cm.

2) The height of the water supply nozzle should be consistent. Moreover, the nozzle of the hot and cold water supply pipe should be perpendicular to the wall.

3) The water nozzle for hot and cold water should be 2 cm higher than the wall. When laying wall tiles, you should also ensure that the nozzle of the water pipe is 2-3mm higher than the wall tiles.

The above is to share with you in detail the basic knowledge about hydropower decoration, hydropower decoration is very common in our lives, and it is also the most problematic, so when you decorate your home, you must be in detail before the decoration, when decorating, and after the decoration involves things, so that you can know the quality of water and electricity decoration, in addition to everyone in the decoration, do not use poor materials in order to save money, and eventually lead to the decoration after the decoration, There is a problem with the water and electricity in the house.

1. The waterproofing project should be done after the construction of the concealed project is completed and accepted.

2. Waterproof construction should be waterproofed with coated film.

3. After the waterproof construction is completed, 2 water storage tests should be done.

4. The waterproof layer of the bathroom should not be less than meters.

5. Floor drains, yin and yang corners, pipelines and other places should be waterproofed one more time.

6. Try not to walk from the ground to the water pipe, and the hot and cold water pipes are hot on the left and cold on the right.

7. The cold water pipe should have a 1cm protective layer in the wall, and the hot water pipe should be, so the groove should be deep.

What details should be paid attention to when installing water and electricity.

The basic requirements for hydropower installation works.

1.The installation of the water supply pipeline must be firm, the horizontal level must be vertical, the components must be complete, the interface should be tight and no leakage, the bracket selection should be correct, the installation spacing should be uniform, the surface of the pipeline should be clean and scratch-free, the functional performance test should be qualified, and the identification of the pipeline should be correct.

2.The installation of the drainage pipeline should be firm, the slope direction should be correct, the components should be complete, the interface should be tight and no leakage, the pipeline must be kept smooth and no blockage, the selection of floor drain should be correct, and the water seal should also meet the requirements to ensure that the surface of the pipeline is not scratched, and the functional test must be qualified.

3.The elevation of the embedded casing should be consistent, the nozzle should be smooth, the height of the casing emerging from the floor slab should be consistent, and the anti-corrosion coating must be evenly brushed. Pipes must be tightly insulated, seamless, and have a smooth surface.

4.The arrangement of the sprinkler pipe should be reasonable, and it should be arranged neatly, in rows and lines, etc. The components need to be complete, and the interface needs to be tight and free of leakage.

5.The installation and layout of the equipment should be reasonable, the arrangement should be neat, the elevation should be consistent, and the operation should be normal to ensure safety and reliability. The paint of pipes and brackets should be uniform, without sinkling, pinholes, bubbles, and consistent color.

6.Ensure that the appliance is installed firmly, the joints with the wall and the ground should be tight and parallel, and the surface of the appliance should be clean and free of pollution, damage, leakage, etc.

Precautions for hydropower installation.

1.Don't buy wires and water pipes casually for the sake of cheapness, the difference between hot and cold water pipes is relatively large, the quality and material are not the same, if you need to use ultra-high-power appliances, be sure to explain to the plumber in advance, and then choose the corresponding wire. It should also take into account the position of the seat and switch, and also need the layout of the furniture to reserve the position of the wire.

2.The pipeline should be laid neatly, not horizontally and firmly, and there should not be too many crosses and bridges. The water and electricity in the kitchen and bathroom should mainly refer to the plan of the first businessman, and do not make your own claims.

3.After the installation of water and electricity, it is necessary to take pictures and save them, so that in case of problems and repairs in the future, the correct location of the water circuit can be accurately found.

1. Pipe slotting.

When installing hydropower, the first thing is to need pipe slotting, which includes two aspects, one is water pipe slotting, and the other is wire line slotting. When the pipeline is slotted, it is best for the owner to check the quality on site to ensure that the horizontal and vertical lines are played before slotting, and the construction is carried out according to the line.

2. Water pipeline installation.

The installation of water pipes in hydropower installation is very important, most of the water pipe materials are PPR pipes, aluminum-plastic pipes, and the installation of water pipes should also pay attention to the placement of faucets, and the owners had better supervise and observe in person, so as to ensure its practicability.

3. Wire wiring.

Wires are a key material in hydropower installation, and the common wires on the market have copper core wires of more than square meters. When installing wires, it is necessary to separate the strong and weak currents, switches, air conditioning sockets and electrical sockets, so that the panel installation at the back will be smoother.

4. Water pipe inspection.

After the construction is completed, it is necessary to carefully check whether there are quality problems in the water pipes, so that the potential safety hazards of the waterways can be eliminated. When inspecting, you can use the method of pressure test, first use the gambling head to bet all the mouths to death, test the water with a pressure gauge, check all pipes and all joints after the pressure, and if there is no water leakage, it means that the water pipe installation is qualified.

What to pay attention to in the installation of water and electricity.

1. When designing the waterway, you should first think about all the equipment related to water, such as water heaters, water purifiers, washing machines, toilets and wash basins, etc., and think about the installation location, method and whether you need hot water.

2. In addition to the water outlets such as wash basins, cloth pools, and clothes machines, it is best to install a faucet in the bathroom to facilitate the connection of water and flushing the ground in the future.

3. It is best to have the property present when conducting the suppression test, so as to play a supervisory role and avoid some decoration teams from deceiving the owners. The method of pressure is to open the "return valve" of the pressure pump to form a circuit to see if there is pressure in the tube, especially for the electric pressure pump, we should pay more attention.

4. After the waterway is installed, it is necessary to pay attention to check whether the waterway in each place is kept unblocked, such as: whether each drain outlet of the faucet such as kitchen, bathroom, balcony is unobstructed. If you find that the drainage is slow or poor, you should get the property unblocked in time.

Home hydropower renovation is not an easy task, in the home hydropower renovation should pay attention to the following three aspects: 1, design the transformation plan in advance 2, do a good job of supervision during construction 3, pay attention to the quality of hydropower materials.

When carrying out the renovation of water and electricity at home, the renovation plan must be designed in advance, and the renovation must not be started blindly, otherwise the renovation work has begun, and I don't know what to do next, and the result is that until the final completion, there are still many things that I want to do, and if I don't design the plan in advance, I always need to add things in the middle of the construction, and the cost of hydropower renovation will often exceed the budget, and the construction period of the renovation will be extended. Before the transformation, the design of the renovation plan also includes the owner has a clear idea of the layout of water and electricity in his home, to determine where the electrical appliances at home are placed, the need to install a few more sockets and a series of problems, in the transformation do not have an idea today and a change of idea tomorrow, which will cause great inconvenience to the construction personnel.

In the home hydropower transformation, do not hand over everything to the construction personnel, in the whole transformation process, must do a good job of supervision, it is best to have someone to the construction site every day to check the construction situation, because the hydropower transformation involves safety issues, must be very careful, and the hydropower transformation is done best not to make changes, once there are any omissions and mistakes due to negligence in supervision, there is no chance of secondary modification.

When carrying out home hydropower transformation, we should pay attention to the purchase of first-class hydropower materials, and choose regular manufacturers when buying materials, there are many hydropower brands now, and it is best to shop around when buying materials.

The project of hydropower renovation at home is very complex, and there are many problems involved, so we should pay attention to the above three aspects when carrying out hydropower transformation.

1. Water pipeline slotting: the line needs to be played first, and then slotted, the pipeline slotting must be parallel and perpendicular, the pipeline must be controlled between 600mm and 900mm above the ground, and the pipeline with faucet must be vertical, and the depth must be controlled at 4cm. After the trunking is opened, the person in charge of the construction should record the size and location of the pipeline line and the water outlet to facilitate future installation.

2. Requirements for installation of pipes in waterways: aluminum-plastic pipes or PPR pipes (hot and cold pipes), and galvanized iron pipes are not used in hidden pipes.

3. Waterway pipeline inspection: pressure test method inspection: the plug blocks the water outlet and presses it with a pressing tool.

4. Pay attention to the details during the installation process: the back lock should be added to the wire pipe to protect the wire and prevent the wire from being damaged when the wire is pulled if there is a problem in the future.

5. The curvature of the line pipe should be 6 times or 9 times the bend, and it is best to bend 9 times, so as to ensure that each thread can be twitched, so that the thread will not feel laborious in the future. 6 times bend means that the inlet pipe is 20 pipes, then the radius of the bend should be 120 or 180

What details should be paid attention to when installing water and electricity.

If you are a first-time homeowner, you must remember that the installation of water and electricity is the most important thing in decorating your house. Plumbing and water installations are covert and are buried inside walls or under tiles. You can't change it at any time.

So I will say a few points of precautions for hydropower installation: first of all, circuit engineering, all electrical control lines and lines must wear PVC pipes. If there is no shady corner at the ceiling and there is a force reduction wall, the line will go from the wall.

The same circuit wire should be laid in the same pipe, the wire diameter is appropriate, and the number of pipes should be so that the cross-sectional area of the pipeline is not more than 40% of the cross-sectional area of the PVC pipe. The bending degree of the wire shall not be greater than 90 degrees, and when it exceeds 90 degrees, it shall be connected with pipe fittings. When the wire is threaded, the strength must be separated, and all the wires must be threaded.

The joints are firm and reliable, and the insulation performance is good (the resistance value is greater than. The layout of the line is reasonable. The fixed position of the switch and socket must meet the requirements, that is, the switch is 1200-1300mm from the ground, and the socket is 300-450mm from the ground.

The direction of each line is clear and orderly. If the indoor area is more than 40 square meters, the air conditioning line should be laid with 4 square millimeters BV copper core wire. This is followed by waterway engineering

All fittings are strong, reliable and have a good seal. The outlet of the open water pipe should be cold at the top and hot at the bottom, hot on the left and cold on the right. Concealed indoor pipes must be pressurized before they can be sealed.

Generally, under the premise that the working pressure is not greater, no decompression phenomenon is qualified. In the waterproofing process, the overall cast-in-place waterproofing generally requires one cloth and three oils, or two cloths and six oils (cross paving). The waterproof layer of the coating must be smooth, uniform, and free of defects such as peeling, shelling, cracks, and bubbling.

The inspection method of waterproof engineering is: water is turned off for 24 hours without leakage, that is, it is qualified. Finally, the materials for the installation of water and electricity also need to be very strong.
