How to construct water and electricity decoration? What are the precautions for water and electricity decoration?

Water and electricity decoration is a complex project. If some points are not noticed, it is easy to cause unnecessary troubles in the subsequent use process, so we should pay attention to every small detail to avoid subsequent problems, so it is extremely important to modify the water and electricity precautions in this installation. Below, we will explain in detail the relevant knowledge of matters needing attention in hydropower decoration, hoping to be helpful to your subsequent project implementation.

Matters needing attention in hydropower decoration

Preparatory work:

1, go through the decoration formalities at the property office (that is, you must choose a good decoration company before decoration, and you must not be careless)

2. Require the property management to coordinate the unfurnished residents upstairs and do a good job in the waterproof experiment upstairs (to prevent water seepage upstairs and the crisis downstairs, and to repair the problems as soon as possible).

First of all, you or your designer should have an overall plan for the layout, brand and location of the kitchen and bathroom.

4. Set up cabinets. On the day of construction, please ask the cabinet master or designer to set the position of the vegetable basin and the required outlet.

5. It is up to the owner to decide whether to use electric water heater or burner to heat hot water. Electric water heaters need brands and sizes.

6. Determine the height of the shower nozzle. The specifications and dimensions of the column basin need to be determined. Owners who have requirements for the bathtub or the whole bathroom need to set the specifications and dimensions before the water reform and provide the water supply reform master. You'd better prepare one or two more water outlets.

The main reasons for improving water supply are: changing open pipes into concealed pipes, and creating personalized water environment according to the population and water use habits of each family in order to save space and look beautiful.

Problems needing attention in water improvement: it is necessary to distinguish between left heating and right cooling, and to suppress the test after construction. It is necessary to sign a quality assurance card and issue a waterway reconstruction map.

Precautions for water and electricity decoration need to be reminded that in some communities, the steel bars in the load-bearing walls are too thick to cut off the steel bars (affecting the quality of the house), so we can only take shallow (thickening cement when sticking bricks) or open pipes, or bypass other walls. If the owner wants to brush waterproof in the tank, he needs to make an appointment in advance, so he should explain it in advance. In fact, our operation technology is standardized, and there will be no seams in the groove, that is, there will be no chance of missing brush, but brushing.

If the owner may consider adding something when changing water in the later stage, and water is needed, then we will reserve 1 and two more outlets according to your requirements, and you can install the faucet when you need it.

Remember: Precautions for water and electricity decoration: The overall layout must be planned before construction to avoid communication mistakes with construction personnel. Our construction is generally in accordance with the conventional construction, so there are special requirements that need to be explained to the construction personnel in advance.

How much is the installation and renovation of hydropower?

First, change the electricity price.

2.5mm2 high-voltage substation unit price per meter 23 yuan,

The unit price of 4mm2 high-voltage substation is 28 yuan per meter,

The unit price per meter of 6mm2 high-voltage substation is 38 yuan, and the unit price per meter of the original pipe wall line is 18 yuan.

5- 15 yuan per box.

Wall punching 10-30 yuan.

Television lines, telephone lines and network lines are all around 20 yuan per meter.

Switch socket 100-200 yuan section.

Second, before the transformation, start with small costs.

There are many factors related to the cost of hydropower transformation, which are closely related to the reservation of developers, the owner's own demand budget, the scale of transformation, the structural transformation of hydropower transformation, design modeling and so on.

If you simply change the water and electricity, you only need to charge according to the actual consumption of the house type, and the labor cost is about per square meter 12-25. For big bags, some home improvement companies include the renovation of kitchen and bathroom water and electricity, and some places charge according to the number of meters changed. The unit price is different, including open pipes, concealed pipes, light walls and load-bearing walls.

Water and circuit renovation can be divided into two prices: slotting and slotting. Some decoration teams divide the slotting price into "non-load-bearing wall slotting and load-bearing wall slotting". We must discuss the prices of different items in advance. Before the hydropower transformation, the owner should negotiate the price with the construction party, and be careful about the price of one pipe, two lines and one line, and how much a cassette costs.

1, waterway

Generally speaking, most builders tell you that after the construction is completed, the price of one pipe passing through two lines is the same as that of two pipes passing through one line. That is to say, the pipe is buried in the tank, and a line is 30 yuan/meter. A tank is also opened, and only one pipe is put in it, but there are two lines in the pipe, but the price is 60 yuan/meter. So you can spend thousands of dollars more at will. Obviously, this charging method is unreasonable. When a pipe passes through two wires, the cost of slotting and threading is the same, only the cost of additional wires is added.

2. Circuit.

Each switch socket needs to be equipped with a cassette. If possible, you'd better buy a cassette yourself. Please report the installation fee to the decoration team. A cassette supermarket sells for one or two dollars, and the construction party often quotes a dozen dollars, and the average family will spend hundreds more.

Third, change the list of hydropower materials.

Water: PPR water pipe, triangle valve, etc. Power: wire (including network cable and telephone line), wire accessories (conduit, tee, cassette, etc. ), switches, sockets, etc.

Underground pipeline: 28 yuan/m, made of PVC. Underground pipelines include: weak wires and conduits, both of which are made of PVC. Among them, the diameter of hard flame-retardant electrical tube is D 16, weak current (telephone and TV network cable) passes through the tube alone, and the switch socket bottom box is 10 yuan/piece; 1 18 15 yuan/set, add 16 information integration box and 160 yuan/set, and then fill them with gypsum or cement mortar to ensure the concealment of concealed works. High-voltage concealed equipment: 35 yuan/m, PVC flame retardant material.

Workers and wires: no more than 3 wires, if each wire exceeds 5 meters. The rest are concealed with weak current. Waterway installation: concealed pipe: 60 yuan/m, made of 20pp-R.

Surface-mounted water pipe: 45 yuan/m, 20pp-r material; sewer pipe installation: 60 yuan/m, 50PVC material.

Weak current surface mounting: 18 yuan/m, others are the same as weak current surface mounting. High-voltage surface mounting: 25 yuan/meter, others are the same as low-voltage concealed mounting. Faucets: specifications:15,20, price 8 yuan/piece.

Water meter: specification15,20, price 25 yuan/main valve: specification 25, price 30 yuan/replacement valve: specification 20,25, price 25 yuan/flushing valve specification15,20, price 20 yuan/water inlet pipe: below specification 40, price 12 yuan/meter.

Lamp: specifications 20W, 30W, 40W, price 5 yuan/ceiling grid lamp: specifications 40W- 120W, price 40 yuan/hood, concealed wall.

Switch: price 5 yuan/socket (3-5 holes): price 10 yuan/ceiling fan: specification 1400mm or less, price 40 yuan/ceiling fan: specification 250mm or less, price 30 yuan/circuit breaker: specification 16A-60A, price/kloc-0.

Note: This price is for reference only! Of course, due to different regions, the price will be different. For more detailed information about relevant prices, please refer to the information provided by local dealers!

Four. Water quality improvement quotation

Water pipe renovation (PP-R pipe) unit price is 38 per meter-46 yuan

Drainage pipe reconstruction (pipe diameter 50 and below) unit price 50-80 yuan per meter.

The valve diameter is 25mm, and the unit price is 65 yuan, and the unit price is 80 yuan.

60 yuan per square meter of toilet sediment excavation.

The above is a detailed answer to the matters needing attention in hydropower decoration. I wonder if you are satisfied with our introduction.
