Common water pipe selection and maintenance work in home improvement
The pipes in the family are divided into cold water pipes, hot water pipes, heating pipes, gas pipes, water pipes, etc. From the material point of view, they are divided into: galvanized pipe, UPVC pipe, aluminum-plastic pipe, PPR pipe, copper pipe and non-embroidered. Several types of steel pipes.
First, the choice of household water pipes
1. Galvanized pipe:
Most of the old houses are made of galvanized pipes. Now the iron pipes for gas and heating are also galvanized pipes. The galvanized pipes are used as water pipes. After a few years of use, a large amount of rust is generated in the pipes, and the yellow water flowing out is not only polluted. Sanitary ware, and mixed with bacteria that grow on the inner wall of the slick, the rust causes the heavy metal content in the water to be too high, 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. The Ministry of Construction and other four ministries and commissions also issued a document clarifying that galvanized pipes will be banned from 2000. At present, galvanized pipes are rarely used in cold water pipes in new residential areas. Some districts use galvanized pipes for hot water pipes. General gas pipes, heating pipes, and down pipes can be used with such pipes. Cold water pipes and hot water pipes should not be used.
2. UPVC pipe:
In fact, it is a kind of plastic pipe. The interface is generally glued. The UPVC pipe has poor anti-freeze and heat resistance, so it is difficult to use it as a hot water pipe. Because its strength cannot be applied to the pressure requirements of the water pipe, Therefore, 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 circles have found that chemical additives that make PVC softer have a great influence on the kidney, liver and testis in the human body, which can lead to cancer and kidney damage, destroy the function of the human body, and affect the development. So I suggest you not to buy. This type of water pipe can only be used for the down pipe, and other types of pipe are not used.
3, aluminum plastic pipe:
Aluminum-plastic composite pipe is a kind of pipe which is more popular in the market. Currently, the market is more famous, such as Rifeng and Jinde. Because of its light weight, durability and convenient construction, its bendability is more suitable for use in home decoration. The main disadvantage is that when used as a hot water pipe, the long-term thermal expansion and contraction will cause the pipe wall to be misaligned and cause leakage, and the water leakage is required to be seen after several years of decoration, so the more people use it now. The less you come. This type of pipe can be used for cold water pipes, hot water pipes and heating pipes. Most of the heating systems now use aluminum-plastic pipes for convenient construction and performance.
4. PPR tube:
As a new type of water pipe material, PPR pipe has unique advantages. It can be used both as a cold water pipe and as a hot water pipe. It is becoming a kind of promotion because of its non-toxicity, light weight, pressure resistance and corrosion resistance. The material, PPR pipe is not only suitable for cold water pipes, but also for hot water pipes and even pure drinking water pipes. The interface of the PPR pipe adopts the hot-melt technology, and the pipes are completely fused together. Therefore, once the installation pressure test is passed, it will not exist as the aluminum-plastic pipe has a long time and the aging water leakage phenomenon. The PPR pipe is said to never scale and never grow. Rust, never leaking, green high-grade water supply materials.
Second, the maintenance work of household water pipes
In the decoration and decoration of family houses, the best way to avoid the leakage of water supply and drainage pipes is to strictly follow the process requirements to ensure the quality of the project. In addition, household drainage pipes should have a sense of regular maintenance. For the cleaning of household drainage pipes, it is necessary to master the correct method, and it is necessary to adhere to prevention and do a good job in daily maintenance of the sewer.
Method: You can use professional pipeline curing agent to clean, disinfect and sterilize the sewer pipe regularly, keep the sewer pipe unobstructed, and avoid the pipeline becoming a breeding ground for pathogens. When cleaning the pipeline, professional pipe maintenance products should be used to achieve sterilization, odor removal and cleaning and anti-clogging effects. When selecting maintenance products and dredging products, pay attention to the safety of the products, and select products with high sterilization rate and testing by professional authorities.
