First, the aging water pipe must be replaced
The existing waterway pipelines of second-hand housing often have many unreasonable layouts. During the renovation, the original waterway must be thoroughly inspected to see if it is rusted or aged. If the original pipeline uses a galvanized pipe that has been eliminated, it must be replaced by a copper pipe, an aluminum-plastic composite pipe or a PP-R pipe during construction. For example, before decorating the bathroom, first stop the floor drain, put water about 5 centimeters deep and test it. If it leaks, you must redo the waterproof work. At the same time, it should be noted that no dead corner can be left after construction.
Second, the circuit can not be transformed
Second-hand housing generally has the phenomenon of simple circuit distribution, aging of electric wires, illegal wiring, and so on, which can no longer meet the electricity demand of modern households. Therefore, it must be completely rebuilt and rewired during the renovation. If it is found that the original line is made of aluminum wire, it must be replaced with a 2.5mm square section of copper wire. For the installation of air-conditioning and other high-power appliances, a 4 mm square section of the line should be set up separately, and a PVC insulated conduit should be used when embedding.
In addition, the new 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 When it is increased, the mobile socket will cause abnormally high temperatures due to poor contact, thus burying hidden dangers for electric shock and electrical fire accidents.
