Which is better, Wei Xing water pipe or Jinniu water pipe?

Which is better, Wei Xing water pipe or Jinniu water pipe? I have heard of these two brands, which are still good, but I have never used them. The following are some points for attention in choosing water pipes, which I hope will be useful to you. 1. Note: 1. Generally, PPR water pipes, steel-plastic water pipes and copper pipes are used in home decoration, and the price of steel-plastic pipe materials is relatively high, while the price of fittings of PPR water pipes is higher than that of steel-plastic pipe materials, and the price of copper pipes is the most expensive, about four times that of PPR pipe materials. 2. When laying water pipes in home decoration, try to avoid laying them on the ground. It is best to run them from the top or the wall. The number of pipelines may increase slightly, but it is beneficial to pipeline maintenance in the future. 3. The wall thickness of hot and cold water pipes is different, so the cold water pipe cannot be used as a hot water pipe. A simple way to distinguish hot and cold water pipes is to mark the hot water pipes with red lines. The standard length of 4.PPR pipe is 4 meters each. When you buy it, you should ask whether the merchant is talking about the price per pipe or the price per meter of pipe. Remember to check whether the pipeline length meets the requirements after delivery. 5. Pay attention to the pipe diameter and wall thickness of water pipes in home decoration. Generally, the supervisor should be divided into 6 tubes, which can be charged with 4 tubes. In order to ensure water consumption, it can also be charged with 6 pipes. 6. When purchasing pipes for home decoration, we should pay attention to whether the inner diameter of the pipes is symmetrical, and the uneven pipe diameter will affect the docking of the two interfaces. 7. The Quality Standard for Home Decoration Engineering of Building Decoration Industry Association stipulates the time and pressure of pressure test: the newly installed water supply pipeline must be pressure tested according to relevant regulations. The test pressure of metal and its composite pipe is 0.6MPa, and the pressure is stabilized 10 minute. The pressure drop in the pipe should not be greater than 0.02MPa, and there is no leakage; The test pressure of plastic pipe is 0.8MPa, and the pressure drop in the pipe should not be greater than 0.05MPa after 20 minutes of pressure stabilization, and there is no leakage. Second, how to choose water pipes for home decoration: 1. Advantages of aluminum-plastic composite pipe: aluminum-plastic composite pipe is a popular pipe in the past, with light weight, durability and convenient construction. At present, there are many kinds of aluminum-plastic composite pipes on the market, and the quantity and price vary greatly. How to choose aluminum-plastic composite pipe has not become a headache for consumers: when it is used as a hot water pipe, it may cause ferrule-type adjacent dislocation due to continuous thermal shrinkage, leading to leakage. 2. Advantages of PPR pipe: As a new type of water pipe material, PPR pipe has unique advantages, such as non-toxicity, light weight, pressure resistance and corrosion resistance. The interface of PPR pipeline is connected by hot melt technology, and the pipelines are completely fused together, so once the installation test passes, it will never leak water. Moreover, PPR pipe will not scale, and it is called a green advanced water supply material that will never scale, rust and leak. Mistakes and fallacies: PPR water pipes have no shortcomings and are the best choice for people to buy water pipes. It is precisely because the production process of PPR water pipes is relatively simple that counterfeit products or unqualified products appear in the market, which brings inconvenience to everyone. Therefore, it is suggested that when purchasing PPR water pipes, we should be on the right track and buy them through good sales channels. 3. Advantages of copper pipe: Copper pipe has the advantages of corrosion resistance and sterilization, and it is an excellent product outside the water pipe. There are two ways to connect copper pipes: clamping and welding. Like aluminum-plastic pipes, ferrules have the problem of aging and water leakage for a long time, so users who install copper pipes mostly use welding, that is, welding the joints together with oxygen, which may never leak like PPR water pipes. Error and fallacy: the price is expensive, and the water supply system in few communities is copper pipe, which is more common in export apartments and high-end villas. 4. The function of stainless steel pipe is similar to that of copper pipe, which is also expensive and difficult to construct, and is generally used less in home decoration. Iii. Problems in installation: 1, the water pipe must be pressurized after installation: the pressurization test is generally carried out under the condition of 1.5 times the water pressure, and there should be no water leakage during the test. 2. Simple non-pressure testing method, but not completely feasible. 1) Close the main water valve. (that is, the water pipe switch in front of the water meter) 2) Turn on the faucet in the room for 20 minutes, and turn off all the faucets after ensuring that there is no more dripping. 3) Turn off the water inlet switch of toilet water tank, washing machine and other equipment with water storage function. 4) Open the main water valve. 5) After opening the main valve for 20 minutes, check whether the water meter moves, including moving slowly. If there is any movement, it is leaking. If you don't move, you may be fine. If there is something wrong with the water meter or the water pipe leaks slightly, it may be difficult to determine. Therefore, it is suggested that the water pressure test must be carried out after the construction, generally 8 kg for 20-30 minutes. It's best to have a look for yourself. Direction of water pipe: It is suggested that it is safest for the water pipe to go up. The main reason is that most of the waterway reconstruction adopts concealed pipes, and the water is characterized by downward flow. If the pipeline is underground, once it leaks, it is difficult to find it in time. Only when water overflows Jinshan or the floor is deformed and leaks downstairs will it be found, and because the water pipe is buried underground, it is difficult to find out the leaking place. At this time, the huge loss is irreparable, and even seriously affects the friendly neighborhood relations; If the water pipe reaches the top, the cost of water reform may be higher, but it is still worthwhile as a long-term investment. Even if the water pipe leaks, it can be found in time, with convenient maintenance and less loss. 4. In daily life, if you find the following situations, please check the relevant pipelines as soon as possible. When the water pipe is underground: 1) The surface of the wall paint is moldy and blistered; 2) The baseboard or wooden floor is black, and tiny bubbles appear on the surface; When the water pipe reaches the top: 1) The ceiling is wet or dripping; 2) The wall brick of the pipeline is wet or seeping.
