Compared to new houses, the renovation of second-hand houses or the renovation of existing ones is more complicated because of the protection of finished products and the partial demolition of houses. In the face of high housing prices, many citizens have joined the ranks of second-hand housing, and some citizens have chosen to reconstruct their old homes. However, when second-hand housing renovations or renovations of old ones, should we pay special attention to any problems?

Meidi Decoration Liu always told reporters that the second-hand housing renovation or the transformation of old houses should pay special attention to water, circuit transformation, and hydropower reform is one of the most complex projects. He emphasized that hydropower reform is best done by referring to the previously renovated water and electricity as-built drawings so as not to injure the main water pipes and other pipelines. If there are no hydropower plans, we must ask the experienced master to construct them. Hua Wei, director of decorative design, told reporters: "In the 90s of the last century, iron pipes were commonly used in houses, and iron pipes would undergo severe oxidation after more than ten years of oxidation. It was necessary to replace them with PVC or PP-R polymer pipes. In two cases: Only partial changes are required for ages of less than 8 years, and parts that are detected to have ageing are covered with insulating tape; all of them over 8 years must be replaced because aging is serious, and older houses have May be the installation of 1.5 square millimeters of wire. And modern home appliances are many, according to national standards, the decoration must use 2.5 mm2 copper wire."
For hydropower reform, Samsung Decoration Design Director added three points. First, the switch panel must be transformed. Liu Nurse's second-hand housing is relatively long and the copper bite in the switch panel jack will relax. Therefore, she needs to replace all the switch panels to prevent fire in use. Mr. Wang’s house’s switch panels only need to increase or decrease according to the actual situation in use; secondly, the distribution box should be replaced. To be on the safe side, Liu Nurse and Mr. Wang’s house need to install new distribution boxes. After the air switch of the distribution box has been aging for a long time, it will fail. Third, if air conditioning is to be installed, it must be connected to the air-conditioning line. For example, the 4P square meters of the vertical 4P air conditioner must be specially used.
