What is the common sense of home improvement water pipe purchase? How to choose a decoration water p

The water pipe is not good, the key is the quality of the material, and it is best to smell and look at it when choosing. Sniff: Smell the water pipes for odors.

Parallel goods pipes are mostly mixed with recycled toxic plastics, which often smell pungent odors. Second look: one look at the color, thickness, gloss of the water pipe, whether the outer wall of the pipe indicates the trademark, specification, temperature, pressure, production batch number, production date and actual origin, aluminum-plastic pipe also depends on the thickness and uniformity of the aluminum layer, and the second is to see whether there is a health license.

Water pipes without a sanitary permit cannot be used in drinking water pipes. Three note: First, we should pay attention to the regular store with pipe authorization dealership; Second, pay attention to whether the pipes and fittings purchased are produced by the same manufacturer; Third, pay attention to the product service card.

1. PPR water pipes, steel-plastic water pipes, and copper pipes are generally used for home decoration water pipes, and the steel-plastic pipes are relatively high, while the fittings of PPR water pipes are higher than those of steel-plastic pipe fittings, and copper pipes are the most expensive, which is equivalent to about 4 times that of PPR pipes.

2. Home decoration and laying water pipes should be avoided from the ground as much as possible, and it is best to walk the line from the top or wall, the amount of pipe may increase slightly, but it is conducive to future pipeline maintenance.

3. The thickness of the wall of the cold and hot water pipe is not the same, and the cold water pipe cannot be used as a hot water pipe, and the easy way to distinguish the cold and hot water pipe is to mark a red line on the hot water pipe.

4. The standard length of PPR pipes is four meters each, and when you buy it, you should ask clearly whether the merchant is talking about the ** or per meter of pipes, and remember to check whether the length of the pipe meets the requirements after the pipe is delivered.

5. Pay attention to the diameter and wall thickness of the water pipe for home decoration, the general general pipe should be in charge with 6 pipes, and the pipes can be selected with 4 pipes, in order to ensure water consumption, the pipes can also use 6 pipes.

6. When purchasing pipes for home decoration, it is necessary to pay attention to whether the inner diameter of the pipe is symmetrical, and the uneven thickness of the pipe diameter will affect the docking of the two interfaces.

7. The "Quality Code for Home Decoration and Decoration Engineering" of the Building Decoration Industry Association has such provisions on the time and pressure of the pressure test: the newly installed water supply pipeline must be pressurized in accordance with the relevant regulations. The test pressure of metal and its composite pipe should be stabilized for 10 minutes, and the pressure drop in the pipe should not be greater than that, and there should be no leakage; Test the pressure of the plastic pipe, stabilize the pressure for 20 minutes, and the pressure drop in the pipe should not be greater than that, and there should be no leakage.

In home renovation, waterway renovation needs to choose the right water pipe. So, what should we pay attention to when purchasing home decoration water pipes? Specifically, it can be summarized into five aspects: looking at the appearance, touching the texture, smelling the taste, listening to the sound, and measuring the thickness.

The first step in buying a plumbing is to look at the appearance. Bad can sometimes be seen from the appearance. The water pipe is impermeable, the surface is relatively smooth, there is no convex and concave situation, and it is also printed with the specifications and sizes of the water pipe and some information of the manufacturer, and some of the water pipes with poor quality will transmit light, and some of the surface is rough, and they dare not produce information on the surface of which shed.

The second step in the purchase of water pipes is to look at the appearance. It's not enough to just look at the appearance, sometimes you need to touch it in person, feel whether the material of the water pipe is pure, no impurities, generally the best water pipe will not feel grinding, very smooth, and poor quality water pipe will feel very scratchy to the touch, which is caused by impure raw materials and impurities.

The third step in buying a water pipe is to smell it. Taste is also a way to buy water pipes. Although the water pipe inevitably smells of plastic, if the smell is particularly pungent and there is black smoke when burning, it is likely that the water pipe is produced from waste materials.

The fourth step in buying a plumbing is to listen to the sound. The method of purchasing sound test of water pipe is mainly to take a sample of the water pipe, let the sample fall freely to the ground, and listen to the sound of the ground. If the sound is dull, the quality is good, and if the sound is very crisp, the quality is not good.

The fifth step in the purchase of water pipes is to measure the thickness. The measurement tool recommends using vernier calipers by cutting a section of water pipe into small segments and measuring the thickness of each segment separately to see if the thickness is consistent at both ends and inside and out.

I believe that through the five steps of looking at the appearance, touching the texture, smelling the taste, listening to the sound, and measuring the thickness, you will definitely be able to buy a good quality water pipe.

When we decorate our homes, in fact, there are a lot of decoration materials are very numerous, often make us dazzled, for a simple example, when we decorate and buy water pipes, I don't know how you choose? Generally, water pipes will be divided into single-layer and double-layer, how should we choose? Which one is better?

After reading this, you won't have to worry about it anymore!

In fact, many friends may choose double-layer water pipes when choosing to decorate water pipes, after all, double-layer water pipes have more than single-layer water pipes are antibacterial layers, so the antibacterial effect of double-layer water pipes will be better, and the sealing will be better, reducing the probability of water leakage.

However, in fact, there are some shortcomings in double-layer water pipes, and some users will say that after using them, double-layer water pipes will be divided after a long time, and at this time you will feel that single-layer water pipes are better to use.

In fact, when buying water pipes, it is still recommended to choose big brands, don't be greedy, after all, drinking water will also be related to our health, especially if you buy a double-layer water pipe with poor quality, there may be stratification in the later stage, so it is recommended to choose a regular channel, if you want to buy a single-layer water pipe, you must remember to choose a water pipe with a thicker water pipe wall, otherwise water leakage will occur later.

You don't have to choose, just buy Jinde tube. Go to a regular place to buy! Small places are fake!

Just ask the plumber to open a bill and buy it!

Water supply pipe: cold water, choose Liansu PP-R. Hot water, optional PP-R, or Rifeng's aluminum-plastic pipe.

Drainage pipe: PVC pipe of Liansu.

Buy the loudest PPR tube from the local brand

Generally, it is ppr, and there are many brands.

When choosing water pipes in home decoration, health and safety factors should be taken into account first, mainly to see whether there are qualification certificates such as the "Approval Document for Sanitary Licensing of Drinking Water Sanitation and Safety Products" and the inspection report of relevant authoritative testing institutions.

But at present, the water pipe for home improvement is mainly divided into two to three kinds, the first is the most popular use of PP R pipe, which has a trace of red maintenance and installation, and a series of advantages, and is not easy to deform, nor easy to burst, but it should be noted that when PPP 2 pipe is used outdoors, or used in a space with temperature changes, it is best to be protected by a layer of insulation outside the pipe, because this kind of pipe is most afraid of wind and sun, or water vapor corrosion caused by temperature changes. The second kind of words is similar to PE pipe and PPR pipe, but it is more suitable for use, in the soil, or the laying of the main pipe, I am a home improvement pipe, it is okay to use this pipe, but the class used is relatively small, because its pipe wall is relatively thin, and then the construction process is more troublesome, its advantage is that the corrosion resistance and wind and sun resistance are very good, basically will not be deformed, or it is endowed with poetry, the third is currently just emerging, basically useless, With stainless steel pipe to make an appointment, its advantage is that there will be no magazine, and then the installation is more convenient, the biggest advantage is that it will not be deformed, but he currently has a disadvantage, is the installation process is more complex, it should be said that the installation requirements are relatively high, but ** is still more expensive at present, oh, the author can consider it himself.
