FAQ about PPR water pipe

Home furnishing in the water pipeline laying, as a vital hidden project, its importance is naturally self-evident. However, there are many brands of water pipes on the market, a variety of product selling points, such as antibacterial, multi-layer composite and other features are endless. In the face of this wide range of choices, most ordinary consumers tend to feel confused, do not know how to start to pick the real quality products.

When shopping for a product, we need to understand which features are the core advantages of the product, which are only secondary features, which are the icing on the cake, and which are superfluous. When we have a clear understanding of these issues, we will be able to make a more informed choice and purchase a product that truly satisfies us.

1. about ppr water pipe colors

Over the past 20 years, the choice of colours for PPR water pipe has been relatively limited, focusing mainly on white, green and grey. However, in today’s market, the colours of PPR water pipe can be described as colourful, blue, purple, yellow, red and so on, covering almost all the colours one can imagine.

Regarding the colour of the pipe, some people may tell you that white water pipes are the best quality because it has the purest materials used. Others may claim that green coloured pipes are the best choice because it stands for green. But in reality, these are some misleading opinions.

The fundamental reason why PPR water pipe have such a wide range of colours is that masterbatches of different colours are added during the production process. In other words, the colour of a water pipe is not a direct reflection of its quality or purity. In fact, PPR raw material is colourless, i.e. transparent, in its initial state. In order to give the pipe its colour, the corresponding masterbatch needs to be added. Therefore, a white pipe is simply the result of the addition of a white masterbatch and is not directly related to its purity.

CONCLUSION: For the colour of PPR water pipe, consumers do not need to be too obsessed. This is more a reflection of the manufacturer’s personalised choice than a measure of product quality. When shopping, we should pay more attention to product performance, quality and other key factors.

2. about ppr water pipe size

There is an ongoing debate about the choice of home plumbing pipe size between 20mm and 25mm.

The first thing to understand is that 20mm water pipes have a smaller diameter, while 25mm water pipes have a larger diameter. This difference in pipe diameter is also directly reflected in the price, with 25mm water pipes usually being more expensive than 20mm ones

But does a higher price always mean superior performance? 

The answer is not absolute. 25mm water pipes are more expensive mainly because of their larger diameter and the corresponding increase in manufacturing costs. However, a larger pipe diameter does result in a higher flow rate, which is a significant advantage. However, not all situations require a high flow rate water pipe. For example, if your home has a 20mm water meter connection, then using a 25mm water pipe , It’s a little bit redundant.

So how do you choose the right size of plumbing? 

I think we should consider factors such as flow rate, economy and water usage habits. In the case of a washing machine, for example, as it uses a fixed amount of water each time, it makes sense to use a high-flow hose to complete the filling process more quickly. However, for showers, if the flow rate is too high, it may lead to an increase in water consumption and hence an increase in water bill, which may not be economical for some households.

CONCLUSION: Therefore, when choosing the size of the ppr water pipe, we should make a decision based on the actual water demand. Different outlets may require different flow rates, which requires us to make comprehensive considerations. Of course, if you don’t have any special constraints on the cost, then there is no harm in choosing a high flow rate water pipe. But in general, it is more reasonable and economical to choose the water pipe size according to the actual demand.

3. about ppr water pipe thickness

Due to manufacturer variations, the actual wall thickness of a ppr water pipe may vary, from thinner to thicker, even when the outside diameter and wall thickness specifications are the same. At this point, some merchants may claim that the thinner wall thickness of the water pipe due to the inner diameter is slightly larger, so the water comes out more smoothly, the flow is greater.

Here is a simple tip to determine the quality of PPR water pipe, touch the inner wall of the pipe with your hand. If the inner wall feels smooth and delicate, it means that the ppr water pipe is of high quality, as it does not easily accumulate dirt and bacteria, thus ensuring clean and safe water.

This view is partially correct, but also misleading. We need to analyse the nature behind it in depth. It is true that a ppr water pipe with the same outside diameter will have a relatively larger inside diameter if the wall thickness is thinner. But this advantage is at the expense of wall thickness. And the wall thickness is directly related to the pressure capacity and service life of the water pipe.

So what exactly should we look for when choosing a ppr water pipe? 

CONCLUSION:  As mentioned before, the flow rate of a ppr water pipe is mainly determined by its diameter specification. Therefore, excessive pursuit of thin wall thickness in order to increase the inner diameter, while ignoring the pressure capacity and service life of the water pipe, is a kind of cart before the horse, the practice of sacrificing the end. I hope you can weigh the pros and cons when choosing and make a wise decision.

4.about ppr water pipe Transmittance

Some merchants may claim that translucent PPR water pipe mean that their raw materials are purer, a claim that is actually misleading. In fact, this is the same as the belief that white water pipes are the purest, and both are inaccurate.

To recap our previous discussion, the raw PPR material itself is transparent and has no colour. But when manufacturing water pipes, why do we add colour masterbatch and not make it transparent? The reason is that we want the water pipe to be impervious to light. Light enters the water through the water pipe and tends to harbour algae plants, which is not good for the use and maintenance of the water pipe.

So why do some ppr water pipes with added colour masterbatch still transmit light?

This is usually because the colour masterbatch used does not have enough coverage. Some traders may counter that if recycled material has been added to the plumbing then the plumbing is not translucent, so to avoid using this type of plumbing, it is better to go for translucent. They will also mention that nowadays plumbing is concealed and regular installations add an insulating casing, so translucency has little effect on the actual use of the plumbing.

Indeed, some of these points are correct. Plumbing installations nowadays are usually concealed and will have an insulated casing added, which makes light transmission really less of an issue for the actual use of the plumbing. However, it is worth noting that there is a national standard for the light transmission of water pipes. If the water pipe fails to meet this requirement, then it is a bit of a stretch to say that it is a good ppr water pipe.

CONCLUSION: Therefore, it is certain that although an impervious water pipe does not necessarily mean a good ppr water pipe, a really good water pipe must be able to ensure that it is impervious to light. When choosing a water pipe, we should focus on whether it meets international standards and not just be swayed by misleading promotions from merchants.

5.about ppr water pipe raw materials

The quality of raw materials for PPR water pipe is the key to evaluating their performance, which directly affects the mechanical properties of water pipes, welding effect and environmental health. However, for ordinary consumers, how to accurately judge the merits of raw materials is a challenge.

Different brands will claim that they use high-quality raw materials, but in actual production, the ratio of raw materials and quality control is often only clear to the brand itself. Therefore, it is not reliable to judge the quality of raw materials only by brand promotion.

So, how do we judge the quality of raw materials for PPR water pipe?

In fact, a simple and practical method is to observe its welding performance. High-quality raw materials usually have a narrow melting range and a stable melt flow rate. This means that when welding, the pipe can melt at the right temperature and the melted material will not be too thin and soft, thus ensuring the quality of the weld. On the contrary, if the raw material is of poor quality, it may have a large melting range and a high melt flow rate. This can result in the water pipe starting to melt at a lower temperature during the welding process and the melted material being too thin and soft for welding. Such water pipes are prone to problems after welding, such as leakage and de-welding.

Why does this happen with poor ingredients?

This is mainly due to the fact that the material may be mixed with impurities or recycled materials, etc. These impurities can alter the physical properties of the material, leading to a decrease in the initial melting point and elongation of the melting process.

CONCLUSION: Consumers can initially judge the quality of the raw materials of water pipes by observing their welding performance. If possible, you can ask a professional installer to conduct a heat fusion test to observe whether the melted material is uniform and stable, and whether the welded pipe is firm and free of defects. This will be able to more accurately understand the raw material quality of the water pipe.

Seeing the essence through marketing

In the purchase of home plumbing, we need to see through the various marketing campaigns to see the essence behind it. First of all, we need to make clear the main function of the water pipe – it is the hidden project of the family water supply system, its most central claim is to ensure that the water supply system is safe, stable and long operation.

  • Safety, i.e. the plumbing material should not contaminate the water in any way. We expect a pure polypropylene material without any unknown or harmful additives. Both explicitly and implicitly, we should ensure the purity of the plumbing material.
  • Stability means that the quality of the water pipes must be consistent and reliable. It is crucial to reduce the influence of human factors on its quality. Instead of relying on after-sales and warranty, we should focus on the stability of the quality of water pipe welding. The only way to prevent problems before they happen is to make sure that the water pipes do not have problems in the course of use.
  • Longevity, on the other hand, stands for the fact that the plumbing should be able to stay with us for a long time and stand the test of time. Selling more is not what we really need if it cannot stand the test of time.

To sum up, when buying home plumbing, we should pay attention to its three essential elements: safety, stability and longevity. Through careful comparison and consideration, choose those plumbing products that really meet our needs.
