Table of Contents

In the different materials of the water pipe, we all know that the iron pipe will rust, PPR plastic pipe will not rust, many friends feel that PPR water pipe does not need to clean. In fact, this is a misunderstanding, PP-R plastic water pipe used for a period of time, the pipe wall secondary pollution is serious, is the growth of bacteria, fungi, become a new killer of human health and potential threat to life.

The only way to keep the water in your home healthy is to clean your pipes regularly.
What advantages and disadvantages does the conduit of all sorts of different material have respectively, what kind of bilge can accumulate?
After reading this article, I believe you will have a deeper understanding of water pipe cleaning!

1. PPR Pipes

As a new type of water pipe material, PPR pipe has unique advantages, health non-toxic, its material is completely composed of carbon, hydrogen elements;
Light weight, density 0.89 ~ 0.91 g/cm3;
Pressure and corrosion resistance;
The inner wall of the pipe is smooth and the resistance is small;
It can be used as either a cold or hot water pipe.
The interface of the PPR pipe adopts hot melt technology. After the hot melt connection of the pipe, it can make the pipe and pipe fittings connected at the interface as a whole, with good integrity. Therefore, once the installation pressure test is passed, it will not be like the aging and leaking phenomenon of aluminum-plastic pipe for a long time.

Moderate Price, stable performance, heat insulation, corrosion resistance, good compression strength, hot-melt connection firm. The inner wall is smooth without scaling, the pipeline system is safe and reliable, and does not leak water. The service life can reach 50 years.


Special tools are needed to connect, the surface of the connection needs to be heated, the heating time is too long or the socket insertion will cause excessive water flow blockage. According to the pressure strength and temperature resistance of pipes divided into cold water pipes and hot water pipes, afraid of ultraviolet radiation, generally unknown. In addition, the inner wall of the pipeline is not smooth enough, it is easy for bacteria to accumulate scale and biofilm.

Bacteria will grow in large numbers in the biofilm environment, so it is recommended to use it for a period of time after cleaning to ensure the safety of the water.

2. Copper Pipe

Copper pipe is the top grade in the water pipe, copper is in the order of chemical activity is very low, then hydrogen is still after, so the performance is stable, not easy to corrosion.
Introduce according to the concerned data, copper can restrain the growth of the bacterium, maintain the cleanness of drinking water sanitation.
There are two ways of copper pipe interface: clamp and welding. The clamp, like aluminum plastic pipe, has the problem of aging and leakage for a long time.
At present, most copper pipe installations use welding, welding is oxygen welded together, so as to PPR water pipe, never leak.
Because of its high price, it is generally used in high-end apartments or villas.

High strength, stable performance, sterilization, and not easy corrosion, can inhibit the growth of bacteria, escherichia coli in the copper pipeline can not continue to reproduce, more than 99% of Escherichia coli and pneumonia bacteria in the copper pipeline 5 hours after the elimination of their own, to maintain the clean drinking water health.


The price is expensive and the construction difficulty is big, in the cold winter, extremely easy to cause heat loss, the energy consumption is big.

3. XPAP pipe

XPAP pipe was a popular pipe on the market, because of its lightweight, durable and convenient construction, its flexibility is more suitable for use in home decoration. In the decoration concept of relatively new countries and regions, aluminum and plastic pipe has gradually lost the market, belongs to the eliminated products.

The price is relatively cheap, may bend arbitrarily, the surface is smooth, the construction is convenient.


Easy to aging, use hidden dangers, short service life, the practice has proved that the joint of the pipeline is prone to leakage.

4. Galvanized Pipe

A long time do not open the water pipe was found to flow out of the “Yellow” water, the old house galvanized iron pipe is extremely easy to occur in such a thing, such a “Yellow” water is also harmful to the human body. China’s Ministry of Construction and other four ministries have also explicitly banned the use of galvanized pipes since 2000.

A complete range of pipe fittings.


As the inner wall is rusty and not smooth, with the use of time, it is easy to hide dirt and breed bacteria on the inner wall, pipe corrosion, rust, affect water quality. China has explicitly prohibited the use of galvanized water pipes for domestic water. Belong to the state to prohibit the use of obsolete products, easy to corrosion rust, leading to poor water flow, extremely easy to cause water pollution.

5. PVC Pipes

PVC pipe is actually a plastic pipe, the joint is generally used for adhesive bonding. It is difficult to use as a hot water pipe because of its poor frost and heat resistance, and cold water pipes are rarely used because their strength does not meet the pressure requirements of the pipes. For the most part, PVC pipes are suitable for electrical and sewage piping. In addition, making PVC become more soft chemical additives phthalein, on the human body kidney, liver, testicles, will lead to cancer, kidney damage, it is not recommended to buy.

Light, easy to install, inexpensive, and resistant to decay.


Poor quality will be brittle and easily deformed by heat.
It has a certain toxicity, relatively easy to penetrate, especially if used in direct drinking water supply system, it has serious harm to the human body.

6. Light gauge stainless pipe

Thin wall stainless steel tube corrosion resistance is not easy to rust, safe and reliable use of impact resistance, thermal conductivity is relatively low.
But the price of stainless steel pipe is relatively high, in addition, the choice of water should be used to resist chlorine in the water chlorine ion stainless steel model thin-wall stainless steel pipe connection welding, thread, sealing, and other ways.

ss pipe


Easy to oxidize and rust, strong impact, low heat transfer, green, is the only pipe material that can be implanted into the human body.


The cost is higher, should use the stainless steel model that bears the chlorine ion in the water.

pipe cleaning before and after

For the long-term water supply pipeline, because the impurities in the water will be deposited on the pipe wall layer by layer and gradually form a biofilm, many harmful bacteria breed on the “hotbed” of this biofilm, causing secondary pollution of water quality and ultimately affecting human health. Therefore, we advise you to order the water pipe cleaning services to clean the water pipe regularly to solve this potential safety hazard in the pipe.
