"Everything is difficult at the beginning" and so is the decoration. With the advent of spring, many owners have started renovations, and hydropower reform is the first basic renovation project in home improvement. As a covert project for home improvement, the problem of hydropower reform is also easily hidden. Hydropower renovation projects, as a part of the larger profits in home improvement, have become increasingly complicated due to the low threshold. Choose a home improvement company or choose a professional hydropower reform company. Who can give the owner a satisfactory home?
Home-built professional hydropower reforms usually include the laying of circuits, the laying of water lines, and the reform of water supply and drainage systems. Their professionalism is far from comparable to other projects. In recent years, with the improvement of the service in the home improvement market, consumers have increased their satisfaction with the price and quality of explicit projects. However, due to the price issue and construction quality of the Hidden Project Hidden Project's Hidden Project, it was difficult for owners to satisfy. For this reason, some homeowners abandoned the home improvement company and instead chose a smaller professional hydropower reform company with a lower price.

Who is more transparent?
The reporter’s investigation found that the owner’s concern for the hidden project was that the cost was not transparent. It is understood that most home improvement companies currently on the market cannot issue specific plans for hydropower reforms when they make preliminary quotations. The biggest headache for owners is the increase in the cost of line modifications and additions during the construction of hydropower projects.
The issuance of hydropower reform maps seems to end owners’ concerns over budget overruns. “Professional hydropower reform companies are the first to solve the problem of transparency in costs,†said Wang Yan, Dongyi Risheng’s hydropower reform engineer. However, he emphasized that the drawings for the hydropower reformation line are very professional. For non-professional owners, it is far from easy to understand drawings.
The reporter telephoned and consulted hydropower reform companies such as Master Tang, Longxuan and Dikang, all of whom promised that there would be no problem of line lengthening. Dichang, a general manager of Dikina Innovations, said that after the actual site survey, an as-built drawing was issued and the project was metered according to meters. If there were problems, the owner could personally measure the length and verify the length to check the budget. However, Zhang Junsheng, the engineer of Yuanzhou Decoration, still has doubts about this. He believes that under normal circumstances, the owner can identify the situation on the site, but it is difficult for the owner to grasp the complex site conditions after the construction.
In addition, one of the most important reasons why many people choose professional hydropower is that hydropower reform companies generally offer cheaper lines and materials than home improvement companies. There were once owners worried about the price advantage that hydropower reforming companies' materials had to "sharpen."
In this regard, the platinum plant said that the overall cost of materials and home improvement companies are basically the same, the general cost of hydropower reform companies lies in lower design costs. Compared with large home improvement companies, hydropower reform companies with simpler institutions have advantages in the cost of corporate management.
Although there is controversy over who is more transparent about the two costs, some home improvement companies have begun to notice the importance of cost transparency. For professional hydropower renovation projects, Zhang Junsheng revealed that Yuanzhou decoration also began to implement new solutions such as secondary submissions, in order to reduce the increase in costs arising from the increase.
Who can be more responsible?
At present, hydropower companies on the market generally propose that owners look for third-party supervisors to take charge of inspections. The warranty period for providing hydropower reforms is usually 5 years. However, the same is the hydropower reform, home improvement companies generally in this project warranty period of 2 years. At present, the warranty period for China's national standard for such projects is two years. Home improvement company professionals believe that the national standard as an industry norm, which is scientific, does not enhance the necessary, the probability of a problem in the hydropower line after 2 years is very small, usually the PPR pipe hot melt problem occurs in the first year, so the 5-year warranty for large Most owners have little significance.
For the majority of owners, the after-sales service during the warranty period is only one part of the responsibility. Many owners are more worried about the connection between the home improvement company and the hydropower reform project. Zhang Junsheng’s engineer gave an example to reporters. The implementation of hydropower line design needs to be linked with the later home improvement. If it is found to be inappropriate, the later transformation is more troublesome. The person in charge of Dikang's engineering department said that if necessary, line adjustments can be made later, but the cost needs to be calculated separately. Dikang, general manager of platinum plant, said at the same time, if the late burst of water pipes and other phenomena, you need to negotiate with the home improvement company responsibility. For this reason, many people are worried that this evolution of negotiations will become a "frustration."
Many consumers said that small companies often give people a feeling of “safeguardingâ€. On the contrary, there are many well-known companies in decoration companies, and they feel that there are relative guarantees.
Hydro-reformation company is difficult to supervise
In the market of home-installed hydropower reform, the reporter only checked the plumbing and electric power transformation application qualification of a company in the Beijing Construction Committee online. Jia Zhongchi, president of the Beijing Building Decoration Association, said that at present, there is no explicit requirement for the qualification of home improvement for hydropower. Therefore, the threshold for hydropower reform is low, and the expertise of hydropower reform units is uneven. Jia Zhongchi also stated that at present no policy has been introduced to govern the hydropower reform industry, and industry supervision is often difficult to penetrate into this small unit of a professional hydropower reform company.
Some home improvement companies believe that hydropower reform companies disrupt the market. However, there are different views that hydropower reform companies are the performance of market segmentation. They aim at customers with limited energy and limited funds.
â– Circuit Modification
Weak lines cannot have connectors
New home: In general, the circuit reconstruction of the new house is mainly based on the increase of ports with weak electricity, and the increase in the location of the power socket is the main reason. For example, if passengers are lying on the Internet phone, the TV is turned into a wall, and the bedside of the bedroom is equipped with a double-control switch. The side of the dining table is the same as the one used for the shabu-shabu pot. It should be noted that all construction is done in accordance with the nearest socket lead to the designated location. Make a 120-degree angle around the corner to keep alive. In addition, the distance between strong and weak electricity is at least 30 centimeters, and the wall can not exceed 50 centimeters. The telephone line and the TV line cannot be wired together in the same pipe. In all weak constructions, the weak line cannot have any connector from the weak electricity home to the designated port.
Old house: In the renovation of old houses, the circuit transformation is more complicated, for example, whether the wire is a copper wire, whether the indoor gate box is shunted or not, and the general gate box is divided into five loops, such as an ordinary socket, in addition to the main gate. Lighting, bathroom, kitchen, air conditioning, etc., check whether the meter has been increased to 10A (40A) meter, if it is still the previous 5A meter and the power supply bureau to apply for a capacity change meter.
â– Waterway reconstruction
Hot and cold water pipe spacing 15 cm
New house: In the process of renovating the new house, the new house should be identified first, usually left-right and right-cold. Generally, the distance between the two pipes is 15 cm and the height is the same. In addition, during the process of grooving, it should be noted that the reinforcing steel bars of the new residential areas are relatively thick and can not be cut off by steel bars. Otherwise, the quality of the house can be affected. Only shallow grooves or clear pipes can be opened or other walls can be bypassed. If there are other requirements in the later period, one or two outlets should be reserved in time for the installation of faucets.
Old house: The transformation of the old house should be carried out before the demolition and reform of the water circuit. After the water circuit reform is qualified, it can only be removed from the field and then the next-door decoration process. The old house waterway is generally iron pipe. It is recommended to replace all the PPR pipes after the water meter, because the iron pipes are easy to rust and break, and it is not convenient to repair them. The PPR pipe adopts hot-melt technology. What is broken from where to repair it? , reduce maintenance costs. In addition, some toilets have water pipes hidden in the steps. It is not recommended to remove the steps to move the sewage pipes. Because the water pipes inside the cement are prone to corrosion and aging, it is easier to damage them if you remove the cement and connect the main road.
â– Quote trap
Look for quotes don't forget to identify materials
Circuit: circuit quotes only quote prices, do not explain the material brand, this time owners can question, such as 20 yuan per meter is the use of national standard wire? The number of wire cross-section? What is the brand? There are some companies do not explain when the quote What is the specific price, such as a wire inside the PVC pipe to walk in the end a few wires? General outlets we are divided into the line of fire, zero line and grounding line, the price quoted is basically a string of three lines. Whether the slotting of the line wall is responsible for sealing or not? Some companies only use slotting, no matter if the sealing slot causes hydropower companies and decoration companies to wrestle each other.
Waterway: If there is only a quotation of meters for the waterway, be sure to ask whether this quotation includes other accessories, such as three links, right-angle elbows, but also find out if the copper water outlet is charged separately. What is the thickness of the wall of the material used in the waterway? Now the wall cold water pipe wall thickness 2.0mm, hot water pipe thickness 2.8mm-3.4mm, it is recommended that all waterway reform is best to use all hot water pipe, the wall thickness is best to use 3.4mm water pipe.
â– Experience says
Coordinating convergence projects is very tired
â— Mr. Zhang, the employee of the business unit
I found a hydropower reform company, on the one hand the price is cheap, on the other hand, I feel very professional, resulting in many problems. At that time, at the time of hydropower reform, the home's electrical appliances were not fixed, so only with the construction staff said that it was reserved according to the general situation. As a result, it was found that some of the outlets were set to be very unreasonable.
Our home bathtub had a nozzle for the general specification, but it was found at the end of the installation that the bathtub was not of the correct size and could only destroy the water and then buried the pipeline. In the reform of the sanitary circuit, I left 4 lines for the Yuba, but I began to look at a Yuba to 6 lines, and later I can only change to another 4 line product.
It is suggested that before the hydropower reform, we must make full preparations, which will save a lot of energy and money for the later period.
