All the fast friends “involved in business†are about to decorate their new house. He is currently worrying about buying hydropower and building materials. The master of hydropower has already opened a purchase order, but he looks at the various water pipes of the business and does not know how to choose authentic brand pipes. Had to post to the netizens of the home forum. Everyone couldn't say why, he suggested that he go to the building materials supermarket.
I am afraid that other renovated owners have such experience, ran into a water and electricity building materials store named some kind of water pipes, the results can take out the brand manufacturers to produce the brand of water pipes for you to choose, the price is still different, let you There is no way to start. Industry sources pointed out that there are more cases of chaos and miscellaneous water brands in the building materials market.
In the words of a power company of a decoration company, the plumbing market has deep water, and there are also many pitfalls. To really understand consumption, I am afraid that only by doing a water and electricity project can I know the inside story.
A brand trap: the same name products, manufacturers of different cases:
The netizen “beautiful for the mood†bought the first batch of Weixing water pipes commonly used in the decoration, but after the construction was completed, it was not enough to find the water pipes, so he went to another roadside shop to buy a few. Although the water pipes he bought twice before and after were all linked to the Weixing brand, the fonts on the water pipes were different, and the owners of the two building materials stores insisted that their own sales were absolutely authentic. He did not know who to listen to. He had to put two kinds of water pipe pictures on the Internet. Please have experience to help identify.
The reporter also encountered this situation in a random interview. A building material store on Hushu South Road, when a reporter stated that he wanted to buy a Weixing PPR hot water pipe, the shop owner immediately asked where to buy the Weixing water pipes. It was said that the prices of different manufacturers were not the same.
“Like Zhongqi Electric Wire, there are a lot of water pipes with similar names.†Jiuding Decoration’s director of power and water should explain that although the names are all Weixing water pipes, the quality of each Weixing water pipe is different, and the prices are also different.
There are also many brothers of the same name selling the larger Pilsa hot water pipes on the market. There are just a few Pilsa hot water pipes that the reporter has learned. They are the Turkish Pirsa pipes (manufacturer is Turkish Pilsa Pipe Industry Co., Ltd. (Originally in Shanghai), Shanghai Pilesa Water Pipes (trademark SHPES, manufacturer Shanghai Piersa Pipe Co., Ltd., origin in Shanghai), etc., as well as pure imported Piersa water pipes.
“People often say that the Pilesa Pipe should be imported from Pilesa in Turkey.†An insider explained that the decoration owner does not understand the water pipe market and generally prefers to purchase pipe with high brand and reputation. The small manufacturers saw the profit growth point and started a brand-name business.
However, each brand of pipe manufacturers has made corresponding protection measures for their products. In order to prevent consumers from buying fake products, Weixing Pipeline specializes on the Internet to explain: Weixing Company currently has several industrial parks, Shanghai Industrial Park, Zhejiang Linhai Industrial Park, Tianjin Industrial Park, etc. Quasi pipe on the "Weixing, China famous brand, national exemption from inspection" and other words. Authentic Weixing pipe industry free test phone calls, telephone consultation, consumers can call these phone calls to verify.
According to industry sources, there are currently two types of PPR pipe fittings on the market that are not genuinely Pilsa (PILSA). One is purely counterfeit Pirsa PPR pipes and fittings; the other is that some companies are trying to apply for permission with Pilsa. Similar trademarks (PILSA) or companies registered with Pilsa as their corporate name also produce PPR pipe fittings.
Hong Guan, head of the China Crown Decoration Hydroelectric Project, teaches consumers a simple approach. He said Hangzhou's larger hydropower dealers (such as Hangzhou Wanshun Hydropower), in order to protect their own pipes from being counterfeited, would normally paste the distributor's phone and store name on the distribution pipe to facilitate consumer enquiries. Help consumers return. Consumers who buy water pipes or purchase fittings from the company's purchasing company are better off looking for big material dealers who sell branded water pipes.
B price trap: use low-cost or counterfeit products to deceive consumer cases:
Ms. Zhu began renovation in April this year. During May, she brought a list of water electricians to the building materials market to add some pipes. After comparing the quotes from several stores, she took orders from the cheaper ones. The merchant asked her to pay the full amount on the grounds of giving her the best price. After the May 1 holiday, water pipes were sent to her home. The plumbers saw the problem at a glance. Ms. Zhu bought tubes that did not meet the specifications of 25 mm in diameter and 4.2 mm in wall thickness. They can only be used as cold water pipes. Miss Zhu had to return and add money to buy a thick tube.
It is understood that attracting consumers to purchase at a low price is a common trick for utilities. A person in charge of the Nanhong Decoration Hydroelectric Engineering Department told the reporter that even though the pipes of some brands have the same pipe diameter, the wall thickness is not the same. For example, Weixing PPR6 is in charge of 4.2mm and 3.5mm. Ordinary consumers go to purchase pipes, and the quotes provided by the stores are often low. The prices that may be reported to you are thin tubes, which make you feel that the store is cheaper. When you want to buy thick tubes, they immediately put the price Pull up, or send a thin tube directly to your home.
Accessories are also the profit growth point for unscrupulous merchants. Mr. Hong, who is responsible for the hydropower project in the decoration of the crown, said that if the prices of the water pipes reported by the merchants on the market are significantly lower, then consumers will have to stay longer. The purpose of these businesses may be to earn money for accessories because the accessories account for half of the expenditure on home-installed plumbing, and consumers often ignore the price of accessories, and will not be true to the business on the accessories, and some businesses will use the fake. Accessories to impersonate. As a result, the merchant's pipe is sold cheaply, but the money on the accessories can make a lot of money.
"Brand pipe manufacturers have a fixed price, merchants get a genuine wholesale price is about 5.5 percent of the pricing, and they bought fake goods from the fake manufacturers are genuine manufacturers of 30% off!" An industry source revealed . The most terrible is not to buy expensive, but the quality of fake goods, but off, the general problem of water supply pipes in the home are mostly in the parts and interfaces, so buying fakes is undoubtedly leaving a leak hidden danger.
C installation traps: pressure measurement 10 minutes perfunctory cases:
The new house of Mr. Qiu’s family, the reader, was brought to the foremen to lead the team decoration in the first half of last year. The decoration was completed in June and stayed in August. In September, it was discovered that the bathroom was leaking. He was puzzled by the fact that even though it was a second-hand house, the water pipes in the bathroom were re-laid. It was clear that the hydropower station had been accepted. Has it leaked for more than a month? He asked the property company's plumber to help repair. The plumber understood at a glance that the interface construction technology of the PPR hot water pipe was not closed, the water pressure increased, and the interface leaked. At this time, Mr. Qiu remembered that his own water pipes did not seem to have been pressure tested.
According to the introduction of Jiuding decoration hydroelectric power director should be good, one of the decoration company's hydropower project inspection and acceptance project is to do pressure test on the water pipe, and the hydropower worker is responsible for the pressure test, which is supervised by the owner or the decoration supervision personnel. If the inspection process finds water leakage, the pipeline will be rectified. In order to avoid quality problems in the future, increase maintenance costs. Renovation of the guerrillas has no responsibility for quality assurance. It is possible to cut corners and cut corners in this area, spend more than 10 minutes perfunctory or simply not accept, Mr. Qiu will not eat a knowledgeable loss.
Famous home decoration engineering manager Zhu Xiaobing told reporters that most of the home company companies installed for the plastic steel pipe, with the pressure pump into the pressure of more than double the normal water pressure, pressure test time is often more than 30 minutes, for It is to ensure that there is no omission in the water pipe interface. After all, the company has to provide five years of water and electricity warranty services for the owners.
The manager of the crown decoration said that some hydropower workers have symbolically turned off the taps and opened the main valve to perform so-called water detection. This is a wrong practice because the tests are only tested with normal water pressure and they are not considered. When the water pressure suddenly increases, the pressure resistance of the water pipe is large enough. To be on the safe side, it is best to have the hydropower worker do a 2-hour pressure test.

1. Household water pipes generally use PPR pipes, plastic water pipes, and copper pipes. The prices of steel and plastic pipes are relatively higher, and the parts of PPR pipes are higher in price than steel pipe fittings. The price of copper pipes is the most expensive and the price is equivalent to that of PPR pipes. Around.
2. Household pipe should pay attention to the pipe diameter and wall thickness. Generally, the main pipe should use 6 pipes and the branch pipe can use 4 pipes. In order to ensure the water consumption, the branch pipe can also use 6 pipes.
3. Lay the pipes as far as possible to avoid paving from the ground, preferably from the top or on the wall. The amount of pipes may increase slightly, but it is good for future pipeline maintenance.
4. When selecting the pipe, pay attention to whether the inner diameter of the pipe is even and the uneven diameter of the pipe will affect the docking of the two interfaces.
5. The wall thickness of hot and cold water pipes is different. Cold water pipes cannot be used as hot water pipes. A simple method of distinguishing hot and cold water pipes is a red line mark on hot water pipes.
6. The standard length of PPR pipe is four meters each. When buying, it is necessary to ask whether the price of each pipe is the price of each pipe or the price of pipe per meter. After the pipe is delivered, it is necessary to remember whether the length of the pipe meets the requirements.
7. The Zhejiang Provincial Building Decoration Industry Association's “Quality Specification for Home Decoration Projects†stipulates the time and pressure for pressure testing: Newly installed water supply pipelines must be pressurised according to relevant regulations. The test pressure of metal and its composite pipe is 0.6MPa, and it is regulated for 10 minutes. The pressure drop in the pipe should be no more than 0.02MPa and no leakage. The test pressure of plastic pipe is 0.8MPa and the pressure is 20 minutes. The pressure drop in the pipe should be no more than 0.05MPa. leakage.
