In home decoration, water pipes are one of the important auxiliary materials, belonging to the category of concealed engineering. It is important to pay attention to their selection, because there are many types and materials of water pipes on the market now, but not all types of water pipes are suitable for household use. Today, Jin Flagship Flag Brother will introduce the types of water pipes and how to route them.

1. Galvanized pipe

This type of water pipe was the main material used for water pipes in the 1980s, specifically for heating and natural gas. The disadvantages of galvanized pipes are very obvious and fatal. They are prone to rusting and bacterial growth, and can only be used in exposed pipes. However, with the increasing development of technology, various high-quality water pipes have been developed, and silver plated pipes have been banned from being used as household water pipes.

2. Aluminum plastic composite pipe

This is a pipeline that replaced galvanized pipes after the 1980s. It is a multi-layer material pipeline, consisting of plastic, hot melt adhesive, aluminum alloy, hot melt adhesive, and plastic from the inside out. It has good insulation performance and the outer wall is not easily corroded; And the inner wall is very smooth, with low water flow resistance; It can also be bent freely, making construction very convenient; The middle aluminum layer can isolate the air and inhibit bacterial growth. But it is not perfect either. To connect aluminum-plastic pipes, a sleeve type joint must be used. Over time, the joint is prone to aging and there is a risk of water leakage.

3. Stainless steel pipe

Stainless steel, as we all know, is a very safe and reliable material with a temperature tolerance of -40 to 120 ℃. However, when installing stainless steel pipes, the requirements and costs for welding processes are relatively high. For household use, pressure welding is usually used, and O-rings are also used for sealing. This type of pipeline is not economically feasible.

4. PP-R water pipe

PP-R water pipes almost meet everyone's ideal appearance of water pipes: ① High temperature resistance. ② Environmentally friendly, pollution-free, and will not breed bacteria. ③ Long service life. ④ Non leaking (using hot melt technology) ⑤ Cheap, generally priced at around 10 yuan/meter. Most of the water pipes now use this material.

5. PVC pipe

PVC pipes are mainly used for electrical conduits and sewage pipes. They need to be glued together when connected, and the frost resistance and heat resistance of this material are not ideal. Therefore, when choosing household water pipes, remember to exclude them directly.

Tips for selecting water pipes:

① Appearance: High quality water pipes generally have a smooth surface, and the model, material, and brand name should be clearly marked on the outside of the pipe.

② Flexibility: High quality water pipes have strong toughness and can be bent freely without any impact. But poor quality water pipes are brittle and prone to cracking or breakage.

③ Heat resistance: High quality water pipes have high heat resistance and will not become soft due to heat. Poor quality water pipes generally soften when exposed to water temperatures greater than 60 ° C.

④ Lifespan: High quality water pipes have a lifespan of around 50 years, while poor quality water pipes typically experience quality issues within 5-6 years.

There are three ways to install water pipes

When decorating, whether the water pipes should be installed on the ground or on the top surface, many homeowners consult. Due to different costs, many homeowners do not know how to choose. Below, we will analyze the advantages and disadvantages of different methods;

There are generally three types of water pipe installation: overhead, underground, and wall installation, which are compared as follows:

1. Pipeline on the ground

Keep sth. in mind! This is the correct installation steps and techniques for home decoration water pipes

Advantages: Easy installation of pipelines, minimal material usage, and short length of water pipe laying. Therefore, if calculated in meters, it is a cost-effective method.

Disadvantages: In case of water leakage, it is difficult to detect, difficult to repair, and may cause significant losses (such as soaking the floor, damaging the cabinets and ceilings of downstairs neighbors), and repair requires prying open the ground.

2. Wall mounted piping

Advantages: Not requiring a lot of materials, easy to repair in case of water leakage, and easy to detect, generally not causing significant losses.

Disadvantages: Pipeline installation is slightly difficult, and horizontal slotting is necessary for the wall. This has no impact on the water pipes, but it can damage the wall, and horizontal slotting is also not allowed by national regulations.

Therefore, this method is not recommended for use.

3. Top mounted pipeline

Advantages: It is easy to repair in case of water leakage, and the leakage is easy to detect. It is not easy to cause significant losses and will not damage the waterproofing of the ground.

Disadvantages: The pipeline installation is difficult and requires a lot of materials, so the owner needs to pay more fees. If passing through the hall, there should be a circle of suspended ceiling or gypsum line to cover it.

After the above analysis, apart from horizontal slotting on the wall, both roof and floor have their own advantages, and the regulations do not specify where to go. Obviously, using a roof mounted water pipe is a relatively safe choice, but the cost is relatively high. Although the cost of using a floor mounted water pipe is low, it is not easy to detect any problems. The specific choice also depends on the billing method of the construction party.

Keep sth. in mind! This is the correct installation procedure and technique for home decoration water pipes.

There are generally two types of billing methods for construction companies. One is to calculate the price by meter, which is to charge as much as possible. Another method is to calculate by square.

If the construction party charges by square meter, it is recommended that the owner and the construction party make it clear in advance that they will all use the roof, as the cost is the same. Of course, it is better to use the roof. If calculated by meters, it is recommended that the owner request the construction party to provide a water and electricity estimate after the water and electricity positioning, and that the fluctuation of the water and electricity estimate and the final cost should not exceed a certain range, such as about 10%. This way, the owner can understand the approximate cost in advance. If they feel that the cost is too high and cannot accept it, they can consider going underground.
