1 Overview Of PVC Pipes PVC-U C-PVC How Chlorine Affects Water PVC-O PVC-Hi 6 Conclusion One of the most popular equipment for plumbing, garage maintenance, and other do-it-yourself jobs is PVC piping. Whether or not they frequently conduct DIY projects, the majority of people are familiar with PVC pipes.

However, you might not be aware that PVC pipe comes in a variety of forms.

It’s crucial to understand how the pipes differ from one another. Every type is designed to perform a specific duty, so picking the right one at the outset will make your life much simpler.

A SUMMARY OF PVC PIPES PVC piping is used by the vast majority of buildings in the modern world for their plumbing systems. It’s virtually a given that PVC pipes make up a sizable component of the infrastructure whether you live or work in a recently constructed structure.

Polyvinyl chloride is referred to as PVC. This particular kind of plastic resists heat and high water pressure without tearing or cracking.
Additionally, plastic is preferred since it has a reduced tendency to leach metals or other materials into the water.
PVC pipes can be repaired far more easily than copper piping, which is another factor contributing to plumbers’ preference for PVC pipes.

PVC is a more environmentally friendly material than copper since it is recyclable and sustainable. Despite being widely distributed on Earth’s surface, copper is a nonrenewable resource.

There is no way to obtain more after we run out. The same is true of numerous different metals that may be utilized to make pipework.

PVC pipes are typically just referred to as plastic pipes by plumbers. People are occasionally shocked to hear that there are numerous varieties of PVC.

There are four different varieties of pipes:

All PVC materials are recyclable and sustainable, whether they are chlorinated (C-PVC), unplasticized (PVC-U), molecularly orientated (PVC-O), or high impact (PVC-Hi). In comparison to metals like copper, they are also much more durable and secure to use.

However, every variety has been tailored for a particular need.
Let’s examine the available choices.

PVC-U pipe

A PVC-U pipe is something you use when you need something that wasn’t made with a plasticizer. Plasticizers are materials that are incorporated into a plastic mixture to increase flexibility and softness.

Since PVC-U lacks any plasticizing chemicals, it is typically significantly more stiff. Additionally, it doesn’t likely to be as smooth as other PVC varieties.
PVC-U can be used for a variety of things, such as:

transporting uncontaminated drinking water, trash, and dirt transferring waste Eliminating industrial waste Drainage systems for industrial contexts the simplest pipes and fittings PVC-U pipes are not prone to bend under pressure. They are typically less expensive and significantly lighter than copper.

PVC-U is preferred by plumbers for transporting drinking water due to its rigidity and adaptability. Over time, they don’t often deteriorate easily.
They don’t experience the same kind of corrosion as other materials because they are also resistant to chemicals and UV exposure.


A PVC pipe made with a lot of chlorine is called C-PVC. They are produced by chlorinating PVC resin.
Around 1960, C-PVC began to be employed in water distribution systems. But there have been issues with the production process.

In addition to chlorine treatment, C-PVC frequently contains stabilizers, lubricants, and colors as additives. This has given rise to certain worries regarding possible water source contamination.

The production procedure has since been enhanced, nevertheless, till the hazards have been reduced.
C-PVC is used today for things like:

transporting water for drinking basic pipes and fittings transporting and getting rid of potentially dangerous liquids in workplaces moving water that is both incredibly hot and very cold Using C-PVC with drinking water is safe. Additionally, it resists rusting. Its ability to resist a far wider range of temperatures is its main benefit over PVC-U.

Because of this, it is frequently used to carry hot liquids in residential, commercial, and industrial environments.

C-PVC is substantially more flexible than PVC-U because it contains plasticizing chemicals. While this makes it more prone to warping over time, it also makes it considerably simpler to install in spaces that call for bending or intricate shapes.

IMPACT OF CHLOROGEN ON WATER Despite worries, it has been established that chlorine has no detrimental effects on the quality of water. In fact, a lot of towns and cities decide to chlorinate water to make the tap water safer.

Many bacterial and viral organisms that can be present in your water are killed by chlorine.

You don’t need to be concerned that C-PVC pipes can contaminate your water supply. Additionally, you shouldn’t be concerned that the chlorine is harming your pipes.

PVC-O pipe

A unique kind of plastic called PVC-O is an engineering marvel. PVC-U can be chemically altered to take on a denser, more layered shape.
PVC-U and PVC-O both lack plasticizing agents. However, it is typically significantly stronger than a typical PVC-U pipe.
These pipes typically cost more since the production process is more complex. They are therefore typically utilized in circumstances when PVC-U is insufficiently stable.
Good instances of where PVC-O can be used are as follows:

Everything in the piping and fittings that will be subject to high water pressure Any sewer systems that cross terrain that could be unstable, such as an earthquake zone pipes used for irrigation that syphon a lot of water Sewer pumps’ primary components are under intense pressure. Even more resistant to corrosion than PVC-U pipe is PVC-O piping. Due to its improved durability, it also does a better job of maintaining water quality.

When there are conditions that could cause leaks with conventional PVC plumbing, municipalities frequently install it.

PVC-O could spare you a lot of headaches if you’re working on a DIY project that involves any plumbing that is frequently exposed to high water pressure. These pipes can function for many years because of their durability and great hydraulic capacity.


PVC-Hi pipe

The most recently developed pipe type is PVC-Hi. This plastic was created by mixing several compounds with normal PVC.
These substances increase the material’s durability and resistance to impacts.
Plumbers like standard PVC plumbing, however it can’t be utilized in all circumstances. It wasn’t always stable enough to compete with metal pipes.
However, PVC-Hi solves that problem by combining PVC and polycarbonate to make an alloy.

One of the strongest materials in the world is known as polycarbonate. It allows for noticeably better stability under high pressure or high temperatures when mixed with PVC.

The PVC resin is resistant to temperature changes and robust enough to sustain significant impacts.
Other PVC-Hi pipes blend vinyl acetate with modified acrylic. These have the same degree of rigidity and impact resistance as the polycarbonate ones.

These robust pipes are utilized in situations when standard PVC plumbing cannot withstand the heat or pressure. It’s probably integrated into industrial liquid transportation networks or commercial sewage treatment facilities.

This substance can also be used to join two pipes together. It is frequently chosen because cutting it won’t cause any damage.
PVC-Hi may be the answer you’re looking for if you’ve been frustrated by damage to standard PVC pipes.
CONCLUSION The various PVC pipe varieties are crucial to your plumbing system. You won’t frequently require anything more sophisticated than PVC-U in its ordinary form.
The lightweight pipes and fittings can be made out of this hard plastic.
But C-PVC could be an excellent option if you require a more flexible pipe. The plasticizing agents in this polymer enable greater flexibility.
The durability is preserved at the same time.

By stacking many levels of PVC-U, a unique kind of plastic known as PVC-O is produced. Although it can be expensive, it is frequently utilized when pipelines are subjected to high pressure.

PVC-Hi is the PVC kind that is the most robust. Since this plastic and polycarbonate mixture is so temperature- and impact-resistant, it is frequently used in large commercial and industrial applications.
