How to do the hydropower transformation of second-hand houses? Hydropower transformation scheme of second-hand house

Many second-hand houses have been used for a long time, and the hydropower system may be old and cannot meet the needs of modern people. Before the renovation of second-hand houses, it is necessary to make a hydropower transformation plan. How to do the hydropower transformation of second-hand houses? Next, I will bring you a second-hand housing hydropower transformation plan, hoping to help you.

How to do the hydropower transformation of second-hand houses?

1. Asking about the service life of houses: For commercial houses that have been used for ten years, there is little difference between the strong and weak electricity of most houses and new houses, and the circuit transformation should be mainly based on local changes; For the second-hand house that has been used for 20 years, the circuit transformation mainly needs to optimize and adjust the original high-voltage system; For second-hand houses that have been used for more than 20 years, the circuit transformation generally needs to remove the original wires for thorough rectification.

2. Check the original conduit: Before the second-hand house circuit is reformed, 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. This can save the cost of wire and tube.

3. Newly-added sockets and circuits should be wired separately: if the quality of the original circuits is no problem, then there is no need to dismantle them, but some new lines and switch sockets should be added on this basis to meet the more needs of the owners. However, it should be noted that the newly added power sockets and other circuits should be wired separately from the distribution box and cannot be connected at will. Avoid adding sockets and lamps to the original circuit, so as to avoid overloading a single circuit and causing tripping or even fire.

4. Grounding protection of the line: The original socket circuit of the old second-hand house may have no grounding wire, generally only two holes, which does not meet the safety standards for power sharing and must be replaced. One method is to replace the main power box and set the grounding in the power box; Another way is to consult the electricity management personnel of the property about the installation location and connection mode of the grounding wire, and never set the grounding wire privately.

5. Weak current system transformation: With the development of smart home, the weak current transformation of second-hand houses has changed more than strong current, and it is often necessary to rewire. 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.

1. Apply for a work permit from the residential area: Before the second-hand house waterway reconstruction, a work permit should be issued to the residential area. When applying, you should bring a waterway reconstruction plan and wait for the approval of the residential property. After completion, the property management office needs to go to the site for acceptance.

2. Material transformation of water pipes: As mentioned earlier, in a house with a long service life, more scale will be formed on the inner wall of water pipes, which will affect the health of family members; Furthermore, galvanized iron pipes used to be mostly used in houses and were oxidized by water for a long time. After the pipeline rusts, its compressive capacity will decrease, which will easily lead to leakage or even fracture. Therefore, the second-hand house should choose whether to replace the water pipe according to the material and service life of the water pipe.

3. Closed water test is essential: before the second-hand house waterway reconstruction, it is recommended to conduct closed water test on the space before the relevant property will be accepted. If you find water leakage, you can find a property to solve it. In order to avoid leakage after transformation, the responsibility is not clear.

4. Water pipe hydrostatic test: After the water pipe of the second-hand house is installed, the hot and cold water pipes should be pressure tested, generally 6-8 kg is appropriate, and the pressure test is not less than 0.6MPa for 20-30 minutes. If the pressure does not leak and the air pressure does not drop, it is considered qualified.
