Which Pipe is Safe for You – PPR or CPVC?

Before going into the specification let’s make ourselves clear what each material is made up of. PPR is the short-form for Polypropylene Random Copolymer while CPVC is Chlorinated Polyvinyl Chloride is produced by a process of chlorination to Polyvinyl Chloride.
PPR is the most widely used plumbing piping system in Europe, Russia, South America, Africa, South Asia, China and Middle East while CPVC is used mainly in India and Mexico. PPR is superior to CPVC not because of wide acceptability but also it is safe for potable water.
Now, let’s help you make a safer decision as to why CPVC Pipes are not safe and why you should prefer PPR Pipes.

Food Grade Plastics:

PPR Pipes are safe for humans as it does not contain chlorine derivatives while CPVC pipes has chlorine in its structure which can get separated and dissolve in the water in the form of vinyl chloride and accumulate in human body.
In several cases, leaching has been found in the case of CPVC pipes as their bond is weak which requires chemical solvent while PPR Pipes are joined together using heat fusion and prevents any type of leakage due to thicker pipe and stronger bonds. Several studies have been conducted in US with respect to leaching of hazards such as chloroform, tetrahydrofuran and acetate into drinking water through CPVC Pipes.

*PPR is a compound of PP.  **CPVC is a compound of PVC/V.

Solvents used in CPVC puts your Health at Risk:

The California State Pipe Trades Council which reviews the health effects of plumbing systems and is a certified body of plumbers in California, USA, have been highly advocative of the hazardous effects of the solvent used to join CPVC pipes. The solvent has been found to contain carcinogenic elements in animals and is considered potentially harmful to humans. On the other hand, PPR pipes does not require any solvent and is joined using heat fusion technique, thus is free of toxic chemicals.

PPR Pipes is the Healthy Answer:

KPT PPR Pipes are manufactured with superior raw materials and are food grade, flexible, stronger and can sustain a temperature range of -10℃ to 95℃. KPT PPR Pipes have very long working life and can last more than 50 years.

Frequently Asked Questions


Two main types of plastic pipes utilized in piping systems are CPVC and PPR. PPR pipe’s tensile strength is inferior to that of CPVC pipe. CPVC is resistant to chlorine as well. Water is cleaned with chlorine. However, extended chlorine exposure might lead to pipe breaks. It may present a fire risk. In addition, PPR is more chemically resistant than CPVC.

Can I Use PPR Pipe For Hot Water Or Cold Water?

PPR is a great choice for hot and cold water systems due to its low coefficient of friction. Less heat is lost as a result, and the liquid’s temperature may stay the same inside the pipe. Additionally, it ensures that there is no possibility of the warmth leaking outside into the surroundings.

Which is Stronger – PVC Or PPR?

PVC and PPR are made from polyvinyl chloride (PVC) and polypropylene random copolymer (PPR). For flowing water, PPR and PVC are both effective. They are also safe to use. On the other hand, PPR can withstand a wider temperature range than PVC. It also conducts heat more effectively. It cannot stand up to high heat; however, PPR can. PPR is also used in various irrigation and natural gas distribution pipe systems.

Why is PPR Pipe Better?

PPR pipe is the best option for your water supply system. The pipes perform well in terms of strength and are resistant to corrosion. Additionally, they are lightweight and safe. They are suitable for projects involving residences, companies, and industries. They are also used in heating and irrigation systems. They can withstand a variety of temperatures and corrosive materials.
