In the process of decoration, from the selection of decoration companies to the purchase of building materials products, many homeowners are unavoidable. However, most consumers still decorate the "outsiders". Even if they stay at the construction site every day, many details cannot be found. Now we will restore the readers to the site of the renovation construction to help you look at your home in a more professional light.

Circuit remodeling PVC pipe and galvanized pipe can be used
1. What is the basis for hydropower reform?
A: The national standard "Residential Decoration Project Construction Code" was implemented in May 2002, and provisions were also made for concealed works in home improvement.
Waterway reconstruction: The laying of pipelines should be horizontal and vertical, and the location of pipe clamps and pipe slopes should meet the requirements of the code. All kinds of valve installation should be correct and flat, easy to use and maintenance; pipelines embedded in walls and floors should be treated with anti-corrosion and protected with cement mortar. The thickness of cold water pipes within the thickness of not less than 10 mm, hot water pipe is not less than 15 mm, Pipe embedded in the ground is not less than 10mm. Pipes that are embedded in walls, floors, or dark deposits should be checked for concealed works; cold and hot water pipes should be installed with left-right hot right-handed cooling, and the parallel spacing should not be less than 200 mm. When the hot and cold water supply system uses the water separator water supply, semi-flexible pipe should be used to connect; installation of various new types of pipes should be performed according to the product specifications provided by the manufacturer.
Circuit modification: When the project is completed, the owner shall provide the electrical engineering as-built drawing; the plastic wire protection pipe and the junction box must be flame-retardant products; the appearance shall not be damaged or deformed; the appearance of the metal wire protection pipe and the junction box shall not be folded Flat and cracks, there should be no burr in the pipe, the nozzle should be flat; the dark line laying must be piped. When the pipeline length exceeds 15 meters or there are two right-angled bends, a pull box should be added; the same loop wire should penetrate the same pipe, but the total number of pipes in the pipe should not exceed 8, the total cross-sectional area of ​​the wire (including insulation sheath) Should not exceed 40% of the cross-sectional area of ​​the pipe; the power line and the communication line must not penetrate the same pipe; the connector that penetrates the pipe line should be located in the terminal box, the joints should be firmly connected, and the insulation tape should be uniformly wrapped. .
2. The location of the gas pipeline left by the developer is not good. I would like to change it. Will the company be required? The worker said he can also change the gas pipeline.
A: The gas pipeline location must be changed to require the gas company's professional construction, otherwise not only prone to disputes, if you randomly change the problem, it is more likely to lead to danger.
There are usually two kinds of materials for the ground-grooved buried wire. One is a traditional PVC pipe and the Other is a metal galvanized pipe. Both materials have their own advantages and disadvantages: PVC pipe is relatively cheap, the price is about 20 yuan / m, but some PVC pipe is easy to step on bad, so that the line is very inconvenient when overhauling; metal galvanized pipe will not be deformed, but also good Metal galvanized pipe is also not easy to rust, the wire can be extracted during maintenance, more convenient, but the price is higher than the PVC pipe, about 40 yuan / meter. Owners who have a more adequate budget may choose metal galvanized pipes as far as possible. Owners who don't have too many budgets may choose PVC pipes with better quality.
Thick pipes can be hidden
Some kitchens have thicker pipes and are not beautifully exposed. Most of the decoration companies take the approach of redesigning the model to hide it, but at the same time it must not hinder the maintenance of the pipeline.
After the circuit is completed, it must be checked
After the completion of the circuit transformation, necessary inspections and experiments shall be carried out, such as the action of the leakage switch, the insulation resistance of the loops, and the electrical power-on, the test light of the lamps and the switch test control. When the concealed project is accepted, the decoration company shall join the designers and provide the user with a set of schematic diagrams of circuit completion, indicating the wire specifications and the direction of the blind pipe.
Wire trough should be horizontal and vertical
During the construction process, the direction of the circuit in the house must be clearly separated according to the drawings, and the installation position of the cassette should be determined on the wall surface, and the preparation of the slot must be made. In the case of opening the trunking, the depth is generally twice the depth of the used wire tube, the wire trough must be horizontal and vertical, the height of the cassette should also be the same, and the distance between two adjacent wire tubes should not be less than 50 cm. After the completion of the line to ensure that the wire can be pulled in the tube.
Closed water test is indispensable
Ground waterproofing is an essential procedure. At present, most home-improvement companies will perform water-retaining experiments according to the regulations after they have finished water-repellent treatment, and check whether there is any water leakage within the specified time. In general, the time for closing the water test was 24 hours, and some closed water tests performed by the decoration company even reached 48 hours.
