After the mop pool faucet is installed, nothing can be corrected; there are too many walls.
In the process of waterway reconstruction, each inlet and outlet should be straightened. After acceptance, cement spout should be used to fix the outlet. Prevent the water inlet and outlet from colliding in the process of affixing the wall tile. Because most of the current pipes are PP-R pipes and are hot melted, it is difficult to ensure that each outlet is very correct. The result of sticking is: When the faucet is installed later, the faucet also squats along with the inner wire elbow of the water pipe. Especially the outlet of the mop pool, shower, and water heater. Prevention and control measures: Waterway transformation is completed, and after acceptance, let waterworkers fix each inlet and outlet with gypsum or cement mortar. Some workers figured things out and fixed them with wooden blocks, iron wire, etc. This is not enough and it is easy to be hit. The acceptance check points for the inlet and outlet are: vertical, parallel to the wall, firm, appropriate length of the wall (according to the thickness of the wall tiles), distance between the hot and cold water outlets (shower), left hot right cold.
Shower mixing valve not installed, a high and a low or hot and cold water reversal.
The mixing distance between the hot and cold water of the shower mixing valve should be 15 plus or minus 0.5 cm. Outside this range, it is not easy to install. And the two outlets should be highly unified. All the taps are turned hot water to the left, turn right to cold water. If your home's tap has left and right cold, and some left and right cold, you will often make mistakes. In serious cases, there will be burns. The key positions are: shower and water heater outlets. If you make a mistake in the shower, there is no way, and you can only rework it. Water heater mouth is wrong, can also be installed with a hose cross, it will be difficult to see. Of course: the water outlet below the cupboard under the cabinet is wrong, but fortunately, it can be installed crosswise without affecting the appearance. Prevention and control measures: When the waterway reconstruction is completed or under construction, each outlet is inspected and a pipe and a pipe are followed. Especially the shower location must be installed correctly. In particular, the shower door should be specially checked for spacing, height and rightness. Corresponding acceptance criteria: water pressure test 8Kg, left hot right cold, outlet straight, shower hot and cold water outlet spacing is correct, the height of the two outlets are the same.
The waterway reform damaged the waterproof of the bathroom and led to the leakage of the wall. Nowadays, more and more people pay attention to the simple decoration. The waterway changes little, that is, add a few hot water, change the water pipe into a dark pipe, and the ground waterproof is basically not moving. The waterworker opened a wall hole directly in the corner and went out to the kitchen water heater. When the hydraulic transformation was completed, because there was no groove in the ground, there was no water closure test. As a result, it was discovered at the time of delivery that the bathroom in the house leaked into the room downstairs or next to it. Have to re-slide the disk, rework, causing great losses. Although some people did a water-retaining test, there was no trace of water leakage in the bathroom downstairs. Then it started to mount magnetic pieces. As a result, the wall of the neighbor’s house was finally seep. It is also a problem with waterproofing. Solution: There is a waterproof requirement in the bathroom and the waterproof layer cannot be destroyed during hydraulic construction. How can we get hot and cold water out of the bathroom? The correct construction method should be: the pipe is opened at the wall of the wall 40cm through the hole, when it reaches the outside, and then down the floor, go to the kitchen water heater. In this way, the waterproof layer of the bathroom wall of 20cm will not be destroyed. In addition, waterproof test must be done when re-applying tiles.
Wall slotted drains, slotted too shallow, wall putty, putty can not cover.
Slots go dark, the slot must be deeper than the outside diameter of the pipe. It's easy to bury the tube in the tank. Especially in the bedroom, hall, hallway walls. Because of the need to paint latex paint in the future, if the slot is too shallow, plus the water pipe bends. Lots of putty are not covered. Can only be a thin layer, or simply a bit thicker to the location of the pipeline, this result is: the wall is uneven, or easy to crack. Especially when the heating is reformed, the temperature of the water pipe is very high, and the putty can easily be cracked.
Solution: First of all, we must allow the hydraulics to open the groove deep enough to avoid trouble. After the tube is welded, it should be fixed with a wooden wedge or copper wire. Prevent water pipes from bulging out of the wall. When the waterway is finally accepted, check all the pipes again to see if there are any pipes that rise above the wall or that are basically flat with the walls. This situation insists on rectification of hydraulics.
The sewer pipe is not protected, resulting in poor or blocked water.
The transformation of the water circuit requires a slot in the wall. It is dirty and there is a lot of ash falling to the ground. There are multiple floor drains and sewage pipes on the ground. If a lot of ash falls into the floor drain and the flow doesn't go, it's in trouble. Because some of the workers are not responsible, they know it has been blocked and they do not say anything. When the work was completed, all the workers began to wrestle. The waterworker said that the mason had dropped the cement into the floor drain. The mason said that the painter had poured the putty into the bucket and poured it directly into the water, causing the solidification to block the water. The painter said that it was done by other types of work. This can't be said. Of course, there is another situation: when the house is submitted, the water is not smooth. Therefore, we must check the floor drain when we are in the room. If we find that there is no water, we will immediately notify the property for maintenance.
Solution: When the workers come into the field, they are required to protect the floor drain with a plastic sheet or something to prevent them from falling into the floor. Finished products are protected and natural peace of mind.
The waterway was completed for pressure testing without seepage, but after completion, it was found that after the completion of the serious water seepage in the wall, pressure was tested and no water seepage was observed. Start the next process, including the tube, affixed magnetic film. As a result, when the pipe was installed, holes were punched in the wall and the hot water pipe was broken. Because there was no water in the hot water pipe or the water was drained early, the water pipe was broken and the workers did not know. When the water heaters were turned on when they were completed, the walls began to seep. Have to rework.
Solution: In fact, it is very simple. After the completion of the waterway, use a hose to connect the hot and cold water pipes so that the hot water pipes are filled with water. When a worker accidentally broke the water pipe, the water quickly blew out due to the pressure of the tap water (3Kg). This will be solved in time. This method can also be used on the circuit. For example, when the restaurant hangs on the roof, the lamp of the restaurant is turned on first, and when the ceiling is opened in the wall, when the hammer accidentally breaks the wire, the lamp will be extinguished immediately. The woodworker knew that the wires were broken. Start repairs immediately. If the lights are not on, when the wires are smashed, and you don't know, the check is very troublesome.
Two lights or lights and sockets can not be used at the same time, use it to trip:
Current commercial housing circuits are generally equipped with multiple leakage protection switches. Some even divide the air conditioner into multiple channels, separate the kitchen circuit all the way, lighting all the way, the outlet all the way. The points are very detailed. If it is a double-storey building, an electric box under the electric box in the upper floor will be controlled separately. Easy to maintain, easy to use, and relatively safe. However, when the circuit is reformed, it is necessary to pay attention to the fact that the fire line and neutral line of each leakage protection switch cannot be mixed. The result of mixing is: often without reason to trip. There is a lamp that can be used normally but it cannot be used with a socket, or the socket can be used normally or it cannot be turned on. Both will definitely trip at the same time. Very annoying.
Reasons: When an electrician reconstructs a circuit, he or she sometimes adds a socket or lamp. Since this position requires only a live or neutral line, it must pull a line from other places. Some electricians would like to save time and draw a line nearby, no matter which line he is.
At the time of completion or even later, the owner discovered that the two could not be used together. After repairs, the electrician also forgot where the cable was. Maintenance is more troublesome.
Solution: Before construction, determine a few routes. Which electrical appliances are controlled by each route? When wiring, it is necessary to check that it is not free to route. Especially in the two distribution boxes of the duplex building, lighting electricity cannot be mixed. At the time of delivery, turn all lights on and check all outlets with an appliance.
The installation height of a room's outlet is inconsistent:
After the circuit transformation was completed, it was found that there were many sockets and switches in each room, air conditioning sockets, dual control switches, closed circuit outlets, electrical outlets, and security outlets and buttons. It looks messy. If each outlet is arranged in place, it is horizontal and vertical and neat. There is no such feeling. In particular, the outlets in the living room are connected one by one. If the height of the connected outlets is not uniform, it is the most ugly. There is even a tumble, but it is not correct. Has a great influence on the overall decoration effect. Although there are connected outlets at a height, there are some small and unequal spacings.
Solution: When constructing, play a horizontal line on the wall. The height of all the sockets should be the same as the height of the horizontal line. Especially the location of a row of sockets. It is not only highly consistent, but also consistent in spacing. Some sockets do not need to be moved. They were originally installed by developers, but their heights are not uniform. This requires the workers to make adjustments, adjust them, and change the back box. If there is indeed an inconsistent socket height, there is room for adjustment between the bottom box and the panel. Can be adjusted downwards.
Attached: Socket height standards: (All is not absolute, all based on the owner's own habits, their own comfort on the line.)
Ordinary power outlets, there is no special requirements, generally from the ground 300mm to 400mm can be.
The height of the switch panel can be 1200mm to 1300mm depending on the owner's height, and generally follows the size of the developer.
The height of the air conditioning socket, the bottom of the cabinet socket, and other common sockets can be generally high, highly uniform and beautiful. Hanging socket height is about 1800mm to 1900mm, or it is decided according to the height of the air conditioning hole reserved by the developer.
The height of kitchen electrical sockets should be designed by the cabinet designer. Before the hydropower reform, let the design of the cabinets look like a drawing of the water and electricity.
One of the sockets in the room cannot be used. Others can be used normally:
In terms of circuit design, the weak current may be a star connection, but the sockets are all connected in series. To do more is to separate the wiring of the sockets of several rooms. Therefore: There is a line of outlets not pressed, and the back outlets will be dead. The developer's concatenation method is to connect the wires through a crimping cap and then separate the line for the socket. The electrician's concatenation method is: directly through the socket to press the two sockets together, one by one to go to other rooms. Some electricians install sockets that are unprofessional, and some lines are not pressed well, causing the back of the socket to run out of power. Some electricians removed the original crimping cap during construction, and the wiring was loose, causing the back of the socket to become dead.
Solution: In the circuit acceptance, use an electric meter for each route to check for short circuit and open circuit. After acceptance, seal the tube. In addition, at the time of handing over, I checked the electrical outlet and checked all the outlets again. After the electrician is finished, give the electrician a circuit diagram indicating the direction of the circuit and the direction of the socket. Convenient for future maintenance.
The signal on the TV line is very weak:
The current closed-course route is still in the nature of concatenation. One string, one plus one amplifier will have little signal loss and will have little effect on the effectiveness of television. If digital TV is to be used in the future, it will no longer be considered for serial connection because the digital signal will cause the signal to drop sharply because of each serial connection. Affected watching programs. As far as the CCTV line is concerned, if it is not properly constructed, it will also cause the TV line signal to be weak. And now many homeowners are using wall-mounted TVs in the living room. The closed routes have to be shifted and the original lines are buried inside. It is very troublesome to repair them. The weak signals are likely to be caused by improper connection of closed routes. Some workers will be able to save time and work, and will directly close the route as if they were connected to the same line. The signal at the end is definitely weak.
Solution: After determining that there are several televisions in your home and there are several places you need to shift, buy a few amplifiers or outlets with a magnifying effect. Of course if each TV line is star-type wiring better.
Frequently forgotten circuit transformation circuit transformation is more troublesome, and in accordance with the actual settlement, one meter is still a lot of money, and some owners want to save some money, the workers will simply do a bit. As a result, some important outlets were forgotten. I feel very troubled when I live. Then take the open line or use a row to expose the outside, how ugly. Some are purely careless workers, buried wires in the shape. For example: In the living room made a TV background wall, made of wooden keel and plasterboard, and finally painted with latex paint, only to find the air conditioning line buried in the wall. The living room cannot be air-conditioned. It certainly cannot work. Only the wall is dismantled. It takes time and money to work. Sockets that are often forgotten are: dual control in the bedroom, bathroom heater in the bathroom, socket behind the model wall, hot pot socket in the restaurant, water dispenser socket, network cable behind the TV (for digital TV), air conditioning line in each room, computer line And network cable, as well as kitchen, kitchen appliances up.
Solution: Design the transformation of the electric wires in each room before construction to ensure that they are not forgotten. The kitchen's socket allows the design of the cabinets, and they are responsible for the circuit drawings. At the time of circuit acceptance, another inspection is performed.
No ground protection, no color, late maintenance trouble:
Ground protection is very important to ensure that household appliances are leaked and electrical personnel are injured. The separation of the wires is also very important because the circuit will be repaired when it is used later. Because the socket is dead or the socket and switch panel are broken. When repairing, if the wires are all colored, it is very easy to install, and even they can be installed. If there is no separation, then just look for an electrician and take the pen. The correct color separation method is: FireWire is red, neutral line is blue, control line is yellow, and ground line is yellow-green two-color line.
Solution: Before the construction, the color separation of the wire should be clearly explained to the construction party. Acceptance of the material when the material enters the market, depending on the brand of the cable, depends on the number of colors? Several specifications (kitchen, air conditioning line to four square, other 2.5 square)? In general, if there is no ground wire, it should be a certain ground wire is broken, the back of the socket is also no ground wire, find the broken place, reconnect a ground wire on it.
The electricity used by the electric pen is no electricity or tripping when it is used: the electric pen measures the circuit and has electricity, but it is found to be dead during use. It may be that the wires are basically destroyed and they must be disconnected, but they are still connected, and a small amount of electricity is also available. However, the use of large appliances cannot be used. The lights or sockets work fine, but they will not trip in a moment. It is possible that a small amount of leakage (common) occurs, for example, when the socket is installed, the wire touches the wall. Or a small amount of short-circuit occurs. It is sometimes used to light the fire, but it is still barely usable, but it will trip in a short while.
Detection method: Measured with a megohmmeter, one test is accurate. The resistance between the wires of all outlets and the ground or between the live and neutral wires should be greater than 0.5 megohms. If there is a small amount of leakage, it must be less than 0.5 megohms. For a powerless outlet, the simple method is to find an experiment with a large electrical appliance (such as a hammer), a socket and a socket.
Kitchen bathroom, the original bottom box sealed directly, can not be repaired later:
The original sockets of the kitchen were numerous. In addition to the changes in the cabinets, many of the original sockets would not be needed, and they would need to be sealed, otherwise it would be too difficult to read. Some electricians gave me a plan to save time and place the sockets to the nearest place. Once the original bottom box was sealed up, if there was a leakage or no electricity, it was only necessary to knock out the magnets when repairing. How to avoid this situation? Some people said: The original socket is not sealed, ready to repair. But this is too ugly. Some people say that the wires in the kitchen go all the way again and it’s a waste of money. A better approach is: The first socket is reserved, ready to repair, all other outlets re-arranged. So all outlets can be repaired. And do not have to come back from the distribution box all the way to the wire. Save money and insurance. If you do not want to go back too many lines. Then be sure to write down the positions of all the sealed boxes and protect the back box. After protecting the thread, the industry inspected it personally. This is also a hidden project.
The wall line walks away, and the wire is broken when nailing the decorative painting on the wall later:
Now decoration is heavy decoration light decoration. There is no need to do more modeling on the wall. First, it is easy to outdated, but it is not environmentally friendly, but also a waste of money. But the empty walls are not beautiful. Just adorn some decorative paintings on the wall. The decorative paintings are hung up, but the sockets or lights are dead. I had so many paintings nailed, so porous, I didn't know where to break the wires. It must be very troublesome to repair. So say: The wall line should pay special attention, it is best to be vertical and horizontal. In this way, when nailing a nail to the wall, looking at the position of the socket and the switch, the horizontal and vertical directions will surely break the line without nailing. But on the ground, in the ceiling, there is no need to be completely horizontal. Because they do not drill holes in the ground, they do not drill holes in ceilings. You do not need to be horizontal and vertical to represent lines, like spider webs. Certainly not. As a home improvement supervisor, we require that the ceiling and floor lines should be as short as possible to reduce the right angle elbow. This facilitates future maintenance.
In the process of waterway reconstruction, each inlet and outlet should be straightened. After acceptance, cement spout should be used to fix the outlet. Prevent the water inlet and outlet from colliding in the process of affixing the wall tile. Because most of the current pipes are PP-R pipes and are hot melted, it is difficult to ensure that each outlet is very correct. The result of sticking is: When the faucet is installed later, the faucet also squats along with the inner wire elbow of the water pipe. Especially the outlet of the mop pool, shower, and water heater. Prevention and control measures: Waterway transformation is completed, and after acceptance, let waterworkers fix each inlet and outlet with gypsum or cement mortar. Some workers figured things out and fixed them with wooden blocks, iron wire, etc. This is not enough and it is easy to be hit. The acceptance check points for the inlet and outlet are: vertical, parallel to the wall, firm, appropriate length of the wall (according to the thickness of the wall tiles), distance between the hot and cold water outlets (shower), left hot right cold.
Shower mixing valve not installed, a high and a low or hot and cold water reversal.
The mixing distance between the hot and cold water of the shower mixing valve should be 15 plus or minus 0.5 cm. Outside this range, it is not easy to install. And the two outlets should be highly unified. All the taps are turned hot water to the left, turn right to cold water. If your home's tap has left and right cold, and some left and right cold, you will often make mistakes. In serious cases, there will be burns. The key positions are: shower and water heater outlets. If you make a mistake in the shower, there is no way, and you can only rework it. Water heater mouth is wrong, can also be installed with a hose cross, it will be difficult to see. Of course: the water outlet below the cupboard under the cabinet is wrong, but fortunately, it can be installed crosswise without affecting the appearance. Prevention and control measures: When the waterway reconstruction is completed or under construction, each outlet is inspected and a pipe and a pipe are followed. Especially the shower location must be installed correctly. In particular, the shower door should be specially checked for spacing, height and rightness. Corresponding acceptance criteria: water pressure test 8Kg, left hot right cold, outlet straight, shower hot and cold water outlet spacing is correct, the height of the two outlets are the same.

The installation height of a room's outlet is inconsistent:
After the circuit transformation was completed, it was found that there were many sockets and switches in each room, air conditioning sockets, dual control switches, closed circuit outlets, electrical outlets, and security outlets and buttons. It looks messy. If each outlet is arranged in place, it is horizontal and vertical and neat. There is no such feeling. In particular, the outlets in the living room are connected one by one.

When repairing, if the wires are all colored, it is very easy to install, and even they can be installed. If there is no separation, then just look for an electrician and take the pen. The correct color separation method is: FireWire is red, neutral line is blue, control line is yellow, and ground line is yellow-green two-color line.
Solution: Before the construction, the color separation of the wire should be clearly explained to the construction party. Acceptance of the material when the material enters the market, depending on the brand of the cable, depends on the number of colors? Several specifications (kitchen, air conditioning line to four square, other 2.5 square)? In general, if there is no ground wire, it should be a certain ground wire is broken, the back of the socket is also no ground wire, find the broken place, reconnect a ground wire on it.
The electricity used by the electric pen is no electricity or tripping when it is used: the electric pen measures the circuit and has electricity, but it is found to be dead during use. It may be that the wires are basically destroyed and they must be disconnected, but they are still connected, and a small amount of electricity is also available. However, the use of large appliances cannot be used. The lights or sockets work fine, but they will not trip in a moment. It is possible that a small amount of leakage (common) occurs, for example, when the socket is installed, the wire touches the wall. Or a small amount of short-circuit occurs. It is sometimes used to light the fire, but it is still barely usable, but it will trip in a short while.
Detection method: Measured with a megohmmeter, one test is accurate. The resistance between the wires of all outlets and the ground or between the live and neutral wires should be greater than 0.5 megohms. If there is a small amount of leakage, it must be less than 0.5 megohms. For a powerless outlet, the simple method is to find an experiment with a large electrical appliance (such as a hammer), a socket and a socket.
Kitchen bathroom, the original bottom box sealed directly, can not be repaired later:
The original sockets of the kitchen were numerous. In addition to the changes in the cabinets, many of the original sockets would not be needed, and they would need to be sealed, otherwise it would be too difficult to read. Some electricians gave me a plan to save time and place the sockets to the nearest place. Once the original bottom box was sealed up, if there was a leakage or no electricity, it was only necessary to knock out the magnets when repairing. How to avoid this situation? Some people said: The original socket is not sealed, ready to repair. But this is too ugly. Some people say that the wires in the kitchen go all the way again and it’s a waste of money. A better approach is: The first socket is reserved, ready to repair, all other outlets re-arranged. So all outlets can be repaired. And do not have to come back from the distribution box all the way to the wire. Save money and insurance. If you do not want to go back too many lines. Then be sure to write down the positions of all the sealed boxes and protect the back box. After protecting the thread, the industry inspected it personally. This is also a hidden project.
The wall line walks away, and the wire is broken when nailing the decorative painting on the wall later:
Now decoration is heavy decoration light decoration. There is no need to do more modeling on the wall. First, it is easy to outdated, but it is not environmentally friendly, but also a waste of money. But the empty walls are not beautiful. Just adorn some decorative paintings on the wall. The decorative paintings are hung up, but the sockets or lights are dead. I had so many paintings nailed, so porous, I didn't know where to break the wires. It must be very troublesome to repair. So say: The wall line should pay special attention, it is best to be vertical and horizontal. In this way, when nailing a nail to the wall, looking at the position of the socket and the switch, the horizontal and vertical directions will surely break the line without nailing. But on the ground, in the ceiling, there is no need to be completely horizontal. Because they do not drill holes in the ground, they do not drill holes in ceilings. You do not need to be horizontal and vertical to represent lines, like spider webs. Certainly not. As a home improvement supervisor, we require that the ceiling and floor lines should be as short as possible to reduce the right angle elbow. This facilitates future maintenance.
