How to transform the hydropower of second-hand houses? Introduction of hydropower transformation of second-hand houses

Part 1: check the waterway of the 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 making the hydropower renovation plan for second-hand houses, you must go to the site in person, carefully understand the specific situation of the house, focus on the hydropower details of the house, and transform the original water circuit in whole or in part according to the situation of the house.

First, the common situation of second-hand housing circuit

1, the circuit has no ground protection.

When accepting second-hand houses, you can open several switch sockets to see if the wires are grounded. Grounding protection refers to a protective wiring method that reliably connects the metal parts of electrical appliances that are not charged under normal circumstances, but may be charged after the insulation material is damaged or under other circumstances with the grounding body by wires. Old houses with a long time generally have no grounding protection, which can not reduce the harm of leakage to people and property after circuit aging or short circuit. Therefore, effective grounding protection measures must be taken.

2, the wire loop is simple

In old houses with a long time, sockets, lighting, etc. are often mixed with one circuit. If several electrical appliances are turned on at the same time, it is easy to cause the electrical box to trip and other electrical appliances cannot be used. However, in the current wire loop design, high-power electrical appliances are all connected separately, and some will be connected by multiple complex loops.

3. The circuit equipment is seriously aging.

On the one hand, irregular construction will easily lead to aging of circuit equipment, on the other hand, the equipment itself will inevitably age with the passage of time. Therefore, when accepting the second-hand houses that have been used for a long time, we must check whether the quality of the circuit accessories is good, and see if there are serious aging phenomena such as rust and damage.

4. There are not enough switch sockets.

According to the national standard, the number of fixed sockets in residential buildings should not be less than 12, but there are still many original sockets in second-hand houses that cannot meet this standard. However, if a large number of mobile sockets are used, when the current load increases, the mobile sockets will produce abnormal high temperature due to poor contact, which will bury the hidden dangers of electric shock and electrical fire accidents. Therefore, in the decoration of second-hand houses, it is necessary to pay attention to adding more switch sockets.

Bian Xiao reminded: There are still many problems in the circuit of second-hand houses, such as insufficient power load of distribution boxes and many exposed lines. The owner needs to check the house carefully to see if there is any corresponding circuit problem.

Second, the common situation of second-hand housing waterway

1. Water pipe materials are in urgent need of replacement.

Due to the limitation of materials, many water pipes used products such as cast iron pipes, galvanized pipes and aluminum-plastic pipes in the past. These materials are easy to breed rust on the water pipe wall and affect the water quality. In addition, the pipeline is in disrepair for a long time, and it is also prone to the problem of dripping.

2. The waterway design does not meet the requirements.

Nowadays, water pipes from the top to the ground have become the default practice in home improvement construction. And if it is a second-hand house many years ago, its water pipes may be hidden on the ground. If there is damage and water leakage, it will easily affect the neighbors downstairs; In addition, the original waterway of the second-hand house is no longer suitable for the requirements of the current owners, and the pipeline needs to be redesigned.

The second part: distinguish the second-hand house circuit transformation scheme.

There are differences in the circuit transformation between new houses and second-hand houses, and there are also differences in the circuit transformation of second-hand houses with different service life. Therefore, the circuit transformation scheme of second-hand houses should be formulated according to the actual situation of second-hand houses in the hands of owners and their own needs.

First, the circuit transformation of second-hand houses with different service life

For commercial housing that has 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 twenty years, the second-hand house wire tube has been renovated.

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.

Third, the offline transformation of second-hand houses.

If there is no problem with the quality of the original circuit, then we can not dismantle it, but add some lines and switch sockets on this basis to meet the needs of the owners. However, it should be noted that the newly added power sockets and other circuits are best wired separately from the distribution box and cannot be wired 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.

Fourth, pay attention to the grounding of second-hand housing sockets.

The original socket circuit of the old second-hand house may not have a grounding wire, but generally there are only two holes, which do not meet the safety standards for power distribution 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.

Five, the second-hand house weak current system transformation

With the development of smart home, the weak current transformation of second-hand houses may change more than the strong current, and it is often necessary to rewire. Before reconstruction, the layout of various weak current lines and the installation position of sockets should be considered in advance.

The third part: beware of water leakage in the second-hand housing waterway reconstruction scheme.

Second-hand housing waterway reconstruction project is more troublesome, which needs to be done seriously to prevent problems in the later stage, and it takes time and energy. Let's take a look at what points should be paid attention to in the waterway decoration of second-hand houses.

First, don't forget to apply for second-hand housing waterway renovation.

Before the renovation of the second-hand housing waterway, the commencement certificate should be issued to the community. 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.

Second, the second-hand housing water pipe renovation

Because the service life has reached 15. Third, the second-hand housing closed water test is essential.

Before the renovation of the second-hand house waterway, it is suggested that the space should be closed for water test first, and then the relevant property should 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.

Four, the second-hand housing water pipe hydraulic test

After the second-hand house water pipes are installed, pressure test should be carried out on the hot and cold water pipes, generally 6-8 kg is appropriate, and the pressure test should be no 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.

Five, save the second-hand housing waterway reconstruction drawings

After construction, it is necessary to draw an accurate waterway reconstruction map and keep it properly, especially for houses with concealed pipes, in order to solve the problem of waterway leakage of second-hand houses in the future.
