Today's second-hand housing has received more and more attention from people. As housing prices have steadily increased, many consumers have been discouraged by new houses. Second-hand housing has become the most popular choice for many people. The most important place for the renovation of second-hand housing is The transformation of hydropower, the house with a long time the circuit will slowly aging, and the circuit is the family most likely to cause security accidents, so it must pay attention to the decoration, for the second-hand housing of the hydropower reform, many people are Is more blind, so when the second-hand housing renovation will always appear a lot of problems, second-hand housing installation and transformation of water should pay attention to what things do.
Second-hand housing installation considerations
Second-hand housing circuit inspection
Many second-hand houses have been used for a long time, and the hydropower system may appear old and unable to meet the needs of modern people. Before formulating a hydropower reform program for second-hand housing, it is necessary to visit the site personally to carefully understand the specific conditions of the house, and focus on checking the details of the house's hydropower. According to the conditions of the house, all or part of the original water circuit will be transformed.
First, the second-hand housing circuit common situation
1, the circuit does not have ground protection
When accepting second-hand housing, you can open several switch sockets and see if the wires are protected by grounding. Ground protection refers to a kind of protection wiring method that connects a wire and a grounding body in a metal part of an appliance that may not be charged under normal circumstances and may be charged after the insulation material is damaged or otherwise. Older homes that have a long time are generally not protected by grounding, and they cannot reduce the damage caused by the leakage of electricity to the personal property after the circuit is aged or short-circuited. Therefore, it is necessary to take effective grounding protection measures.
2, simple wire loop
Older homes, such as sockets and lighting, often use a circuit, and if several appliances are opened together, it can easily cause the electrical box to trip and cause other appliances to become unusable. In today's wire loop design, power-intensive appliances are routed separately, while others will use more complex circuit wiring.
3, serious aging of circuit equipment
On the one hand, non-standard construction will easily cause the aging of circuit equipment. On the other hand, the equipment itself will inevitably become old as time passes. Therefore, the use of a longer time second-hand housing, in the acceptance, you need to focus on looking at the quality of the various parts of the circuit is good, see if there is no corrosion, damage and other serious aging.
4, switch socket is not enough
The national standard stipulates that the number of fixed sockets in civilian houses should not be less than 12, but there are still many existing second-hand housing outlets that do not meet this standard. If a large number of mobile sockets are used, when the current load increases, the mobile socket will cause abnormally high temperatures due to poor contact, burying hidden dangers of electric shock and electrical fire accidents. Therefore, when renovating a second-hand house, it is necessary to pay attention to adding more switch sockets.
Second, the second-hand housing waterway common situation
1, water pipe materials need to be replaced
Due to material limitations, many of the previous water pipes used cast iron pipes, galvanized pipes, and aluminum-plastic pipes, and the pipes of these materials were susceptible to water quality due to rust. In addition, the pipeline is in disrepair for a long time and is prone to the problem of leakage of dripping water.
2. The waterway design does not meet the requirements
Now that the water pipes have been kept aloof, it has become a default practice for home improvement construction. If it is a second-hand house many years ago, its water pipes may be hidden on the ground. If there is a broken water leak, it will easily affect the neighbors downstairs; in addition, the original waterway of the second-hand housing is no longer suitable for the requirements of the current owners and needs to be renewed. Design piping.
Third, second-hand housing reform proposal
1, it is best to replace the wire hose
Compared to the new house decoration, second-hand housing renovation in the end what lines of the transformation, which can be retained? Refurbished network supervision said that taking electric wires as an example, old houses before 1995 will not normally use copper core wires, but aluminum wires that are prone to aging. It is best to replace them again in the second renovation.
In addition, the water pipes of some old houses are made of galvanized materials. After many years of use, these metal pipes are prone to rust and rot and form very heavy water bases that affect the quality of drinking water. It is also recommended to replace them with PPR pipes. If it is indeed inconvenient to replace the pipeline with a PPR pipe during the second renovation, a corresponding drinking water filtration device should also be added for it.
2, waterproof works must be redone
In addition to wires and pipes, waterproofing should also be an issue that must be addressed when retrofitting and renovating existing homes. The retreaded network supervisor said that the new commodity house also saves a lot of work in this respect. Usually the developer will carry out a waterproof test on the house before handing it in. Generally, there is no problem in terms of waterproofing. However, after many years of use in old houses, there is a possibility of water leakage. The owner must remind the home improvement company to do a waterproof test before the renovation.
In addition, when decorating second-hand houses, if you need to replace the tiles, you should pay special attention when you move the tiles. Try to avoid shattering and waterproofing when the tile is shaken, causing problems. Therefore, if the second-hand housing has been removed from the decoration of the tiles, it should be re-tested later to ensure there is no problem with the waterproof.
3, the power transformation needs to increase the socket
With more and more household appliances, lighting and lighting equipment are becoming more and more colorful, so there are many places need to add switches and outlets. Before proceeding with second-hand housing renovation, it is best to plan ahead and do wiring work during the renovation. The switches and sockets reserved for previous old houses are generally not enough.
In general, a room must have at least 3 outlets. There should be no fewer than 15 sockets in a two-bedroom residential building and no less than 8 switches. The switch height of the same room should be the same, the general switch is 1.4 meters from the ground, and the outlet is 0.3 meters from the ground. The switch of the entrance and the living room should be set in a place easily accessible to the owner.
In addition, attention should be paid to the distribution box when carrying out power transformation. Many old houses have relatively old power distribution settings, and the power ratio is not reasonable and needs to be reset. Refurbished network supervision reminded the owners that when reconfiguring the distribution box, the air-conditioning is best for single-distribution lines, lighting single-channel settings, common outlet single-loop settings, and kitchen and bathroom outlets as required to make single-loop settings.
4, weak electricity is best to re-clothing
In the past two years, people's demand for weaker lines has increased. Many of the telephones, TVs, intercoms, and networks are not considered in the old houses. This requires the owners to re-route the second-hand houses. Refurbished network supervision reminds home improvement owners that when discharging network lines, it is necessary to first determine whether the owner is using residential broadband or installing ADSL on their own, and accordingly determine where the routers in the home are located. In addition, when installing the intercom system, an electrician is also required to operate the construction according to the specifications to ensure that the sound or image is clear.
5, galvanized pipe is recommended to remove all
The galvanized pipes and valves used in many old houses are often leaking, slipping, etc., and are not easy to hold water. They are not good-looking and are inconvenient to use. It is better to replace them all. Refurbished network supervision told the reporter that when carrying out the water supply and drainage transformation, it is necessary to first dismantle the original pipeline and determine the new kitchen and bathroom water supply positions such as showers, wash basins, toilets, washing machines, and sinks. When replacing piping, always close the main valve to avoid water leakage.
