Second-hand housing renovation compared to new home decoration complex, especially some second-hand housing water circuit system is relatively old, can not meet the needs of modern people's lives. Therefore, the transformation of the water circuit has become not only the focus of second-hand housing, but also one of the most expensive projects. Unlike the bright exterior of a house, interior projects such as water circuits are hidden in every corner of the house. Once a problem arises, it will seriously affect daily life, and it will become the most important part of the acceptance project.
Before renovation
Check the water circuit risks
Many used homes have been used for 5 years or more and more than 10 years. Most of them have problems such as the aging of water circuits and the lack of use of functions. Many of the “old†old housing water pipes are cast iron pipes, and the pipes are huge and bloated. The rust that grows year round in the inner wall of the pipes is very likely to affect the water quality, and the pipes that are not in repair may have “running, running, dripping, and leakingâ€. And other issues. The circuit load of the old room is often difficult to meet the needs of large-scale electrical appliances such as air conditioners, water heaters, microwave ovens, and ovens, so it needs to be replaced at the time of decoration.
Before the renovation, it is very necessary to check the existing use of the water circuit, especially whether the house has been renovated before and whether the water circuit has been changed. Industry sources said that if the second-hand housing of hydropower can reach the current use of standards, can reduce the amount of transformation of the project, but also can reduce a lot of costs.
For example, you can check whether the waterway pipe has been changed to PVC pipe, the toilet is using the new type of floor drain, and the floor drain of the old house is generally iron floor drain, the use of time is too long, easy to cause poor drainage pipes, affect the bathroom drainage.
When checking the circuit, pay attention to whether or not to perform wiring in the manner of branching. In general, the home circuit should be "three branches," indoor lighting, sockets, high-power electrical appliances go all the way, some of the old room circuit is not only intertwined, and the circuit is still out of aluminum, aluminum circuit aging rate Fast, prone to short-circuit, leakage and other dangers, and the current circuit decoration is used in copper wire with a diameter of 2.5 to 5 square millimeters, so if the house's circuit is aluminum wire, it must be modified.
It should be noted that the water circuit structure of the old house is more complicated. Before the renovation, it is best to provide detailed wiring diagrams of the indoor water circuit for the construction party to facilitate the construction workers to check the circuit conditions and avoid unnecessary pipeline and line destruction. If there is no circuit diagram, it should be done by a professional electrician and plumber. After the inspection, the demolition will be carried out again.

Watch out for the pipeline being packaged
Many designers stated that if the budget for renovation is limited, the largest fund should be invested in basic projects such as hydropower reforms to avoid future changes in waterways and circuits that cannot meet the needs of use. This would be tantamount to a second renovation and would be costly. More manpower and material resources.
The realization of hydropower projects is "one and every time" and the material of the pipeline is particularly important. Unqualified pipelines are buried in walls. Once a problem arises, it is difficult to find the source and it is extremely difficult to maintain. Therefore, in the decoration of the water circuit, we must pay attention to whether the pipeline material is too hard.
It is understood that in the formal home improvement company, accessories such as wires and water pipes are collectively distributed by the company. The company name is clearly identified on the pipe body and the line body. Workers cannot purchase accessories through other channels to adjust the package.
However, it should be noted that in some construction sites where there are omissions, there will be workers modulating the decoration materials, especially if the work is busy and they cannot take care of their own homeowners. It is even more necessary to pay attention to whether the workers have changed the original decoration materials. Therefore, during the decoration of hydropower projects, it is advisable to regularly check the materials used for the work and verify whether the materials are provided by the home improvement company. If it is found that the material is transferred, it should be immediately reflected to the home improvement company.
In addition, the decoration of construction materials will often occur during the decoration of the road guerrillas and non-standard small decoration companies. In particular, some workers will replace or escort the owners who lack decoration experience to purchase materials, and will often choose some inferior materials. Get extra profits.
Industry insiders remind consumers that if construction materials are provided by workers, they should be inspected to see if they qualify. The advantages and disadvantages of wires, pipes, and other materials are very well recognized. The insulating layer of high-quality wires is tightly bound with the copper core wire. It is also very “weighty†on the hands. The insulation of poor quality wire is not tightly bound with the copper wire, and some There was even a cracking phenomenon, and the diameter of the copper core wire was thin. The inner wall of the better-quality water pipeline is strong and smooth, and the interface is smooth. The poor quality water pipeline is very rough. Industry insiders suggest that the purchase of accessories such as wires and water pipes is best purchased in a professional building materials supermarket.
After renovation
Focus on checking hydropower reform
Acceptance after the completion of the renovation is indispensable. The focus of completion acceptance is the acceptance of the "surface" project and the hydropower project during the renovation. According to industry insiders, the inspection of the home improvement company should be done by the supervisor of the home improvement company before the inspection. Then the owner will examine the project items one by one in accordance with the provisions of the contract, and then check and accept the order of the contract to avoid any errors.
After completion of acceptance, the home improvement company will settle the final payment. If problems are found in the reconstruction of the waterway, repairs must be made and the increase and decrease items that appear during the renovation process must be measured and verified.
Hydroelectric project "secondary" acceptance
Although during the mid-acceptance of the renovation project, the waterway has been pressured and closed, the circuit installation has also been checked and accepted, and the water circuit project has been provided with basic quality assurance. However, the hydropower project also involves the installation of waterway accessories, electrical accessories, lamps, and electrical products. Therefore, after the renovation, the hydropower project is still one of the focuses of project acceptance.
Circuit installation acceptance is mainly through lighting test, switch control to check the lighting, power is normal, the owner can also use electrician professional test pencil to test each socket to see if it is power, and then all the switches are open to check if there is a problem .
Waterway installation acceptance is mainly to check whether the pipeline is firm, you can open the faucet to check the patency of the outlet pipe, and then check the position of the joints and elbows whether there are drops of water or leakage, use wipes to wipe the joints, elbow to see if there is Water leakage phenomenon.
In addition, it is also necessary to check whether there is a phenomenon of "flooding" and "backslope" in the room with floor drain. You can turn on the faucet or shower, and after a certain period of time, see whether the flowing water on the ground is smooth and there is no phenomenon of local accumulation of water. In addition to this, it is also necessary to check whether the floor drain, the toilet and the wash basin are clean.
Seeing hand touch to check the paint job
Acceptance of the paint should be followed by visual inspection and feel in natural light after the paint has dried. When checking and accepting, check the type, color, and coating of the paint for consistency with the model. The paint surface should be smooth, smooth, clear varnish wood grain, no surface falling and wrinkled skin and other conditions, the color should be basically the same and no brush pattern. In addition, the latex paint on the wall should be free from peeling, brushing, and bottoming.
Tile test flatness
Acceptance of wall tiles and floor tiles The first step is to see whether the brick surface is flat, whether the brick surface gaps are regular and uniform, and whether the brick surface has broken or collapsed angles. It is also necessary to pay attention to whether the tiles and the waist line are positioned correctly, and there is no misalignment or height error.
In addition to external considerations, wall tiles and floor tiles are also specially tested for their internal hollowing rate. You can use a metal hammer to gently tap the four corners of the wall and floor tiles to see if there is a hollow sound. The partial emptying rate of walls and floor tiles cannot exceed 5% of the total paved area, otherwise shedding problems will occur.
Wooden work needs to be flexible and easy to use
The wooden doors produced on site shall be checked for the reasonable opening direction of the doors, whether they are flexible when they are opened, and whether they are blocked or rebounded. In addition, it is also necessary to check whether the door joints are reasonable, the door joints above and below the wooden door cannot exceed 3 mm, and the bottom joints are generally 5 to 8 mm. In addition, it should be checked whether the joints of the door covers are tight.
For the cabinet door, it is necessary to check whether the switch is normal and the door should be operated with lightness and no noise. In addition, check whether the door handle and various locks are installed correctly.
