Matters needing attention in hydropower transformation of second-hand houses
First, the second-hand housing circuit transformation
1. is related to the service life of the house.
There is little difference between the basic strong and weak electricity of a commercial house with a room age of ten years and a new house, and the circuit transformation can be partially modified appropriately; If the room age is less than 20 years, optimize and adjust the main high voltage system of circuit transformation; Second-hand houses with a room age of more than 20 years need to remove the original wires for thorough rectification.
2. Check the original catheter
Before the circuit reform, it is necessary to check the quality of the original conduit. If the catheter has been damaged, the original catheter cannot be used. If the catheter is well preserved, the wires in the catheter can be replaced directly.
3. The new socket and circuit should be wired separately as far as possible.
If the quality of the original circuit is not too bad, you can keep it, just add some wires and switch sockets on the basis. However, it should be noted that the newly added sockets are best wired separately from the distribution box, and random wiring is not allowed. Avoid adding sockets and lamps to the original circuit to avoid overloading a single circuit and causing unsafe factors.
4. The original line must be protected by grounding.
The original socket circuit probably has no grounding wire, which does not meet the electrical safety standards and must be replaced. One method is to replace the main power box and set the grounding in the power box; Or consult the property power management personnel about the installation location and connection mode of the grounding wire, reminding the owner that it is absolutely forbidden to connect the grounding wire without authorization.
5. Weak current system transformation
With the development of smart home, the weak current transformation of second-hand houses has changed more than the strong current, and it often needs to be rewired. Before the transformation, we should take a long-term view and consider the layout of various weak current lines and the installation position of sockets in advance.
Second, the second-hand housing waterway reconstruction
1. Water pipe material needs to be replaced.
Most of the water pipes of second-hand houses are made of iron, which is easy to breed rust and so on.
2. The channel design does not meet the requirements.
The current water pipe design is to walk on the roof instead of on the ground, but if it is a former second-hand house, it must walk on the ground instead of on the roof, so it is necessary to check whether the water pipe design meets the requirements and see if it is necessary to redesign the water pipe.
