Water and electricity renovation is the most important part of the renovation. Everyone has heard of the so-called “decoration event, water and electricity first.†The first thing to do in the renovation of a house is to change hydropower. The hydropower projects in our homes are closely related to our lives and cannot be overlooked. Therefore, the quality of a good hydropower project must be checked when housing is accepted. So how much does home-installed water and electricity cost one square ? Because of the labor cost of each place, the variety of materials is different. Of course, the price is different. So it's hard to say how much a house of water and electricity is a square .
Home-installed water and electricity how much money a square
Because of the labor cost of each place, the variety of materials is not the same, the price is also different, and now many decoration companies are counted by meters, how much is done, so it is difficult to say how much money a square meter, it is more difficult to calculate, water and electricity installation The price is divided into three major parts:
1. Weak current installation section.
2. Strong power installation section.
3. Waterway reconstruction section.
A weak installation.
Weak electricity includes two points:
1. Lines: Cables used in telephone lines, network cables, television lines, audio lines, audio lines, video lines, background music, etc.
2. Line pipe: PVC rigid flame-retardant electrical pipe diameter D16 line pipe 3 weak electricity (telephone, television network cable) to wear the tube alone. Switch socket bottom box 86 type 10 yuan / month; 118 type 15 yuan / month. Add 16 information integrated boxes plus 160 yuan/set. After ensuring that there is no joint in the pipe and the trap pipe is buried, fill it with plaster or cement mortar. Dark pipe price: 28 yuan / meter. Ming tube price: 18 yuan/meter
Material: 1 PVC pipe thickened cold bend pipe wire.
2. Power installation.
Flame-retardant electrical pipe not more than 3 threads, such as over 3 roots plus 5 yuan per meter. The wires in the tube have no joints, and the junction box is used at the point of distribution. Switch socket bottom box 86 type 10 yuan / month; 118 type 15 yuan / month, 4 square meters plus 10 yuan per meter. Multiple pipes and slots are billed by multiple dark lines. After grooving the tube, fill it with plaster or cement mortar.
Dark pipe: 35 yuan/meter
Ming tube: 25 yuan/meter
Material: PVC wire thickened cold bends, wires.
III. Waterway reconstruction
a.20PP-R water pipe (dark): 60 yuan / m b.20PP-R water pipe (surface mounted): 45 yuan / m c. launching installation (50PVC pipe): 60 yuan / m PS: PP-R The tube is Weixing or Kinder. The water is a plastic pipe
1. Each meter has one equal-diameter and different-diameter pipe sleeves and one 90-degree elbow.
2, does not contain valve hardware
3, 25 pipes plus 10 yuan per meter
4, less than one meter by one meter
5, drilling another charge, bearing wall 40 yuan / month, non-load-bearing wall 20 yuan / month
6, PP-R pipes are thick 2.8 hot water pipes.
7, under the water pipe calculated by 50 more than 50 to negotiate.
Note: This price is for reference only! Due to geographical differences, of course, the price will be different. If you want to know more about the relevant price details, please use the local dealers to provide!
Home-installed hydropower considerations
First, the circuit decoration waterproof precautions
1. The design of the circuit needs to take all possibilities, availability, and feasibility into consideration, and it needs to be confirmed again and again.
Second, the flexibility of the circuit is also a key factor. It must be understood that concentrating electrical plugs on a patch panel is definitely better than wall-fitting sockets.
2. The distance between the socket and the ground is usually 30 centimeters, and the minimum must not be less than 20 centimeters. If you install a low cabinet or a tatami, the distance from the floor can be adjusted upwards. At the same time, the short cabinet and the wall must be kept a little distance, otherwise it may block the socket. Second, the optimal distance between the switch and the ground is 130 cm.
3. If the circuit is to be rebuilt, the line capacity must be referenced to the actual power usage. If an instant electric water heater is installed, the wire must be a standard 4 square millimeter.
Second, waterway decoration waterproof precautions
1. Some decoration teams will deceive the owners in some areas, and the suppression test is one of them. If the owner supervises the site when the pressure is applied, it can be observed whether the “backwater valve†of the pressure pump has a loop. If there is a loop, it seems that there is not much pressure in the actual operation of the working pressure pump. New house water and electricity decoration notice reminds: Especially need to pay attention to electric pressure pump.
2. Deep-water floor drains cannot be used in the laundry area. If it is installed in the shower room, due to the relatively small amount of water, the deep-water floor drain can basically meet the needs. However, the speed of water discharge from a washing machine is very fast, and the amount of water discharged is also very large. However, the speed of water discharge from deep water floor drains is relatively slow, so it is very likely to cause water overflow.
3. The installation of hot and cold water pipes requires special attention to the following points:
1) The distance between the water pipes should reach 15 cm. The distance between the water taps of the water taps of the electric water heater is 15 cm, and the individual is 10 cm.
2) The height of the Sheung Shui mouth should be the same. Also, the hot and cold water pipes must be perpendicular to the wall.
3) The cold and hot water nozzles are 2 cm higher than the wall surface. When laying a wall tile, you should also ensure that the water pipe nozzle is 2-3mm higher than the wall tile.
Editor's summary: The decoration of the hydropower budget is the bulk of the decoration company. The difference lies in whether he has clearly stated everything to you from the very beginning, what additions and costs are involved, and so on. We only understand each item clearly and clearly so that we can avoid losses and grasp the quality of decoration.
