Which plastic pipe is best?

Best potable water pipe

The use of plastic in the piping sector is increasing to the detriment of metal pipes. From the beginning of its implementation, these generated a huge expectation within the industry due to its properties, low costs, time saving and handling advantages, and it has been a real revolution for the vast majority of professionals. In addition, it must be taken into account that plastic materials are suitable for the conduction of drinking water as they do not cause or transmit any kind of taste, odor or color in the water inside.

CPVC (Chlorinated Polyvinyl Chloride) is a derivative of PVC with a higher chlorination. CPVC has a characteristic yellow color.Advantages:    The main advantage of CPVC pipe over PVC is that it can withstand high temperatures and can carry both hot and cold water. CPVC also has a wider range of uses than PVC by offering a similar outside diameter to copper pipe. It is the ideal system for industrial process water applications. They are often more cost effective than metallic pipe, have ideal flow rates, and are the perfect system for industrial process water applications. Ease of installation. Little or no maintenance. Safe to install and safe to operate:    Fragile material, has difficulty withstanding very high temperatures. Another disadvantage of CPVC is its high coefficient of thermal expansion making it inadvisable for climates that experience wide temperature variations. In addition, CPVC tends to cost twice as much as standard PVC.

Which is better copper or pvc pipe?

When it is necessary to change the pipes of a house it is important to choose good materials. These do not have to be the most expensive, but they must meet a series of qualities so that the drinking water pipes are of quality and durable.

The plastic pipes are being the most used in the canalization of the water inside a house. Much of their success is due to their low price compared to metal pipes. In addition, the new materials make them very resistant, with great durability, inert and not susceptible to corrosion, and it is not necessary to use welding in their assembly. This avoids one of the most delicate points of pipe installation. The welded joints are the most sensitive points to leaks, breakage or the appearance of oxides.the most common plastic pipes for drinking water are: It is a very economical and resistant material. It is used to transport water at high pressures. Its main disadvantage is that


The main competitor to CPVC in certain parts of the KSA region is polypropylene (PPR) or green pipe. Relatively new to the market, PPR has left some homeowners, plumbers and tradesmen questioning which is better for their home.

In addition, CPVC’s rigidity requires fewer fasteners and supports to be used during installation and makes it the best material for vertical plumbing and risers. In contrast, PPR system installation can be costly and time-consuming, requiring special equipment and more skilled personnel. Heat welding can also lead to the formation of beads around the inside of the pipe, which reduces water flow and increases the chances of bacterial growth. Finally, it requires additional space for assembly, which means that parts of the system must be prefabricated.

Chlorine and chlorine dioxide are often used as disinfectants for drinking water. When chlorine and water mix, they can form hypochlorous acid, which is known to break down pipe material.

Types of water pipes

The installation of the hydraulic system in a new construction or in an extension of the same one demands an exhaustive analysis to determine the type of materials that must be used so that the functionality of the same one guarantees to operate for the greater possible time in a correct way.

However, we must point out that both have very similar characteristics: they are light, withstand the passage of time well and their cost is not high. They differ only in the way they are joined and in their resistance to expansion cycles. Therefore, when it comes to choosing one type of pipe or another to install in the home, the decision is not an easy one.

Copper is an inexpensive, light, durable and elastic metallic material that can be cold bent and is recyclable, so it is widely used in plumbing, refrigeration and heating works. Its integrity prevents it from losing its qualities over time, and it can even be recycled while maintaining its physical and chemical properties intact.

In addition, it does not deform at high temperatures and offers good protection against contaminants in the domestic water supply, i.e., it inhibits the development of bacteria, viruses and fungi, thus contributing to improving the quality of the water we drink”.
