“Hidden project†refers to the pipeline engineering and structural engineering concealed in the interior of the decoration surface in home decoration, including electrical circuit, water supply and drainage, gas pipeline, and internal structure for fixing and supporting the weight of the decoration. The reason why the “hidden project†is prone to problems is because there is a lot of human factors involved in it. That is, irregular decoration teams and decoration companies are greedy for the benefit of the moment, and they work on “hidden projects†and “short of the twoâ€. "Shy shoddy" and so on.
Kohler bathroom (from Xin) Â Cano tile
Not long ago, Ms. Lei, who lived in a district of Gonghe Road, leaked from her home drainage pipe. When the staff of the property company repaired, she found that the drainage pipes of her kitchen and toilet had been beautifully decorated and buried under the floor tiles to find drainage. The reason for leaking pipes is to open the floor tiles. Looking at the more leaking water, Ms. Lei had to let the staff open the floor tiles. Upon inspection, it was found that the drain pipe in Ms. Lei's home was due to improper decoration and material selection, resulting in plugging leakage.
First, it is important to choose materials
Drainage pipes should be qualified products with the manufacturer's name, brand, and specifications. The water supply pipe adopts threaded connection. Exposed threads shall be provided at the connection. After installation, the pipe card shall be used to fix the connection pipe. The connection between the pipe and the pipe fitting or valve shall be firm and shall not be loosened. After the pipeline is installed, check the water and check for leaks by visual inspection and feel. Check all the faucets, whether the valve is installed flat, whether the opening is flexible, whether the water is open and whether there is leakage. Check if the water meter is working properly.
Reminder: For special circumstances, special care must be taken to avoid causing future problems. For example, the pipeline is very long, connecting the kitchen and the bathroom, or leading to the balcony. The pipeline must pass through the living room or the room. Because the pipeline is not buried in the wall or is laid under the floor, once the problem occurs, the consequences are serious, so there should be no joints in the middle. And to properly enlarge the pipe diameter to avoid clogging. The hot water pipeline shall not use galvanized iron pipes to prevent the pipes from rusting and generating scale, and heat insulation measures shall be taken.
Second, how to choose the common home improvement water pipe?
The pipes in the family are divided into cold water pipes, hot water pipes, heating pipes, gas pipes, and sewage pipes. From the material point of view, they are divided into: galvanized pipes, UPVC pipes, aluminum plastic pipes, PPR pipes, copper pipes, and not embroidered pipes. Several types of steel pipe.
1, galvanized pipe: Most of the old houses are used galvanized pipe, and now the type of gas used for gas and heating is also galvanized pipe, galvanized pipe as a water pipe, a few years later, the pipe generates a lot of rust, The outflow of yellow water not only pollutes the sanitary ware, but also contains bacteria that grow on the rough inner wall. Corrosion causes excessive levels of heavy metals in the water, which seriously endangers the health of the human body. In the 1960s and 1970s, developed countries in the world began to develop new types of pipes and banned galvanized pipes one after another. China's Ministry of Construction and other four ministries also issued a document stating that galvanized pipes have been banned since 2000. At present, galvanized pipes have rarely been used for cold water pipes in new communities, and hot water pipes in some communities use galvanized pipes. This kind of pipe can be used for general gas pipes, heating pipes and sewage pipes. Do not use cold water pipes and hot water pipes.
2. UPVC pipe: It is actually a kind of plastic pipe. The interface is generally glued. The UPVC pipe is not good in antifreeze and heat resistance, so it is difficult to be used as a hot water pipe, because its strength cannot be applied to water pipes. Because of the pressure requirements, cold water pipes are rarely used. In most cases, PVC pipes are suitable for wire and sewage pipes. In addition, in recent years, the scientific and technological community has discovered that chemical additives that can make PVC softer have a great impact on the kidneys, liver, and testicles in the human body. This can lead to cancer and kidney damage, as well as damage to the human body's functional reengineering system and affect development. Therefore, it is recommended that you do not buy it. Only water pipes can use this type of water pipe, other types of pipes do not use this type of pipe.
3, aluminum plastic pipe: aluminum plastic composite pipe is more popular on the market, a pipe, the current market is more famous in Japan and Jinde, due to its light weight, durable and easy construction, its flexibility is more suitable for home wear Used in. The main disadvantage is that when used as a hot water pipe, the long-term thermal expansion and contraction will cause the wall to be misaligned and cause leakage. The leakage is still visible after a few years of renovation, so the more people use it now. The less you have come. Cold-water pipes, hot-water pipes, and heating pipes can all be used in this type of pipe. Most aluminum-plastic pipes are now used to change the heating. The construction is convenient and the performance can also be achieved.
4, PPR pipe: As a new type of pipe material, PPR pipe has a unique advantage, it can be used as a cold water pipe can also be used as a hot water pipe, due to its non-toxic, light weight, pressure, corrosion resistance, Being a popular material, PPR pipe is not only suitable for cold water pipes, but also for hot water pipes and even pure drinking water pipes. PPR pipe interface using hot-melt technology, the tubes are completely integrated together, so once the installation of pressure test passed, will not exist as long as the aluminum-plastic pipe aging leakage phenomenon, PPR pipe, said never scaling, will never be born Rust, never leaking, green advanced water supply material. At present, there are many PPR pipes in the country, which are mixed. It is better that the domestic Rinpo, Tianli, and Kinder are also good.
Third, do a good job in conservation work
In the home decoration, the best way to avoid the leakage of water supply and drainage pipes is to strictly follow the technical requirements to ensure the quality of the project. In addition, household drains should have a sense of regular conservation. For the cleanliness of household drains, we must master the correct methods, and we must adhere to prevention and do a good job in the daily maintenance of sewage pipelines.
Method: You can use professional pipe curing agents to regularly clean and disinfect and sterilize sewer pipes, keep sewer pipes open, and prevent pipes from becoming breeding grounds for germs. When cleaning pipes, professional pipe maintenance products must be used to achieve the effects of sterilization, odor removal, and clean and anti-clogging. When choosing maintenance products and dredging products, we must pay attention to the safety of the products and try to select products that have a high sterilization rate and are tested by professional and authoritative organizations.
At present, the losses caused by pipeline leakage are more prominent in “concealed construction†violations. Since the installation of pipelines is not easy to check, after construction of all pipelines, construction workers have not passed water injection and pressurization in accordance with the relevant regulations to check whether they run or run. Phenomenon such as drip, leak, etc., was handed over directly, and it was difficult for consumers to find problems with the naked eye. Once problems were found, the consequences were serious.
