The type of PVC (polyvinyl chloride) that is most commonly used for plumbing is known as DWV (drain-waste-vent) PVC piping. This type of PVC piping is strong, lightweight, and resistant to the types of corrosion and degradation that can occur naturally in plumbing systems.
It is available in various sizes and grades, and is typically readily available from most home improvement stores. DWV PVC pipe and fittings are installed in many homes and commercial buildings, and is a great choice for most plumbing applications.
Can Schedule 40 PVC be used for water supply?
Yes, Schedule 40 PVC can be used for water supply. PVC or polyvinyl chloride is a strong and durable material used to make a variety of plumbing pipes. It is a type of plastic pipe that is cost-effective, lightweight and easy to install.
Schedule 40 PVC is made up of both thin and thick walls, with a thicker wall that can handle higher pressures. While it is available in various sizes, Schedule 40 PVC is typically used for water supply pipes because its thicker walls provide the strength necessary for carrying the increased flow without breaking or leaking.
Additionally, PVC is resistant to corrosion and other kinds of deterioration, making it a viable and reliable option for water supply applications.
What is the difference between Type A and Type B PVC pipe?
The primary difference between Type A PVC pipe and Type B PVC pipe is the thickness of their walls. Type A pipe has thinner walls compared to Type B. This makes Type A pipe less durable and more prone to cracking than Type B.
Additionally, Type A pipe is less resistant to temperature change, making it advisable for projects that need consistent temperature levels. On the other hand, Type B pipe is more durable and better able to withstand temperature fluctuations.
This makes it a great choice for exterior and underground applications. To further differentiate the two types of PVC pipes, Type A pipe is pressure rated up to 100psi while Type B pipe is pressure rated up to 315psi.
Type A pipe also has a slightly larger outer diameter compared to type B pipes. Therefore, when these two types of pipes are connected, a specialized fitting must be used to ensure proper sealing.
Is PVC OK for main water line?
There is some controversy surrounding the use of PVC for main water lines. PVC piping is common and is typically used for drain and vent lines where there is no risk of drinking the water. While PVC piping is strong, rigid and generally reliable, it can leach chemicals into the water over time and some experts argue that it is not suitable for drinking water.
If the PVC pipe is used for carrying drinking water, then it is important to make sure the proper chemicals and stabilizers have been added to the pipes in order to prevent any potential health risks.
Additionally, it can be difficult to insulate PVC piping, which can lead to condensation and frost when hot or cold water is traveling through it. Some research suggests that if a laser-welded inner core is used instead, then PVC pipes can be a reliable option for main water lines.
Factors like personal preference, budget, and local regulations can play a role in deciding if PVC is okay for main water lines. Ultimately, it is best to consult a certified plumber for professional advice about whether PVC is the safest option for the specific installation project and individual circumstances.
What is Type A and Type B in SWR pipes?
Type A and Type B are two types of water service pipe materials specified by AS/NZS 4020:2005 – Testing of products for use in contact with drinking water. Type A and Type B pipes are often referred to as SWR or Ring-Seal pipes, due to their distinct form.
Type A pipes are usually made from thermoplastic materials such as PVC or PP, and feature a strong, versatile ring seal jointing system. The pipes are joined together by a ring seal joint, which is a sleeve that fits over one end of the pipe section and seals it in place ready for connecting to a second pipe.
The jointing system forms a watertight seal, maintaining the security of the water supply system.
Type B pipes are usually made from metals such as ductile iron, stainless steel or copper, and feature a rubber ring joint which is perfectly suited to applications that demand a sturdy and permanent connection.
This type of joint forms a fully water-tight seal when the pipes are fitted together, while still allowing axial flexibility. The rubber ring joint creates a kind of additional ‘cushion’ which is able to take any pressure movement while still retaining its water-tightness.
Overall, both Type A and Type B pipes are reliable and strong materials when it comes to maintaining the security of a water supply system. In many locations, a broad range of localised regulations on the types of piping that can be used for water transport, and so it is important to ensure that the correct type of pipe is chosen for the job.
What are the grades of PVC pipe?
PVC pipes are manufactured in two grades – Schedule 40 and Schedule 80. Schedule 40 PVC pipes have thinner walls than Schedule 80. Though they both typically have the same outer diameter, there are differences in their inner diameters.
Schedule 40 pipes have smaller inner diameters than Schedule 80 pipes.
Schedule 40 PVC pipes are suitable for residential projects such as water and drain lines, sprinkler systems, and vents. Schedule 80 pipes are usually used for larger commercial projects and for areas that require a higher water pressure, such as outdoor and underground use.
The chemical composition of Schedule 40 and Schedule 80 pipes is different with Schedule 40 having the highest chlorine content. Due to its higher chlorine content, Schedule 40 pipes are more resistant to chemical corrosion than Schedule 80.
However, Schedule 80 pipes are more durable and have a higher bursting pressure than Schedule 40.
It is important to select the right grade of PVC pipe for a particular project. Additionally, both grades of PVC pipes come in different lengths and sizes depending on the application, so it is important to determine the right size and length before making a purchase.
What is class A PVC pipe?
Class A PVC pipe is a type of piping that is made from a rigid and strong type of thermoplastic called polyvinyl chloride (PVC). This type of pipe is most commonly used in plumbing and drainage systems, both residential and commercial.
It is also used in specialty applications such as medical gas piping, fire suppression systems and chemical waste systems. Class A PVC pipe is generally available in nominal pipe sizes ranging from 1/8” to 16”, and come in a range of wall thicknesses to suit different applications and operating pressures.
PVC pipes are resistant to most acids, bases, salts and organic solvent; however it is not compatible with solvents such as acetone and chloroform. Despite the wide range of resistance to chemicals, Class A PVC pipe is not recommended for use with hydrocarbons, petroleum-based oils or fuel mixtures.
PVC pipe is also resistant to water, UV radiation, corrosion and abrasion, making it an economically sound choice for many plumbing and drainage applications. The versatility and durability of Class A PVC pipe also make it an ideal option for a variety of applications, due to its low cost, ease of installation, and energy efficiency.
What are the different pipe grades?
There are different grades or ratings for pipes that are based on their strength, durability, and resistance to pressure. Generally, pipes can be divided into four main grades. These four grades include:
Grade A: Grade A is the lowest grade of pipe and has the lowest amount of strength. It is usually made of thinner material than other grades and is used mainly in low-pressure applications.
Grade B: Grade B is typically stronger and more durable than Grade A and is used in a variety of low- and medium-pressure applications. It may also be referred to as standard pipe.
Grade C: Grade C is usually stronger and more durable than Grade B. It is mainly used in high-pressure applications and must meet certain government standards.
Grade X: Grade X is the highest grade of pipe and is the strongest and most durable. It is used in extreme pressure applications and must meet stringent government requirements.
Overall, each grade of pipe has its own unique characteristics and is used for various applications. It is important to select the grade of pipe that best suits the specific needs of the project.
Which type of PVC pipe is best?
The type of PVC pipe that is best for a particular application depends on several factors, including the job being done, the amount of pressure the pipe will be exposed to, the type of material the pipe will be exposed to, and other considerations.
For example, CPVC pipes are highly resistant to high temperatures and corrosive liquids, making them a great choice for hot water supply lines and piping subjected to water with higher levels of acidity.
On the other hand, Schedule 40 and Schedule 80 PVC pipes are both made for different applications, with Schedule 80 pipes usually having thicker walls and more resistant to high-pressure scenarios.
For most basic projects using PVC pipe, Schedule 40 PVC is typically the most economical and durable choice. Its strength and durability make it an ideal choice for plumbing, irrigation systems, or backyard projects.
They are also cost-effective and can be found relatively inexpensively in local home improvement stores.
In addition to the type of PVC pipe, the size and length must also be taken into account. To accurately select the right type of PVC pipe, consult with a knowledgeable professional or consult with a reputable online resource.
Which PVC pipe is for underground water supply?

It is cost effective and weather resistant making it the preferred type of piping for installations that are underground. It is also resistant to corrosion and chemical damage, making it a great choice for outdoor projects.
Additionally, Schedule 40 PVC pipe comes in a variety of sizes, making it ideal for many different types of applications.
Is PEX or PVC better for water lines?
When it comes to water lines, the best material to use is dependent on the specific application and installation requirements. PEX (cross-linked polyethylene) and PVC (polyvinyl chloride) are two popular options for water lines due to their ease of installation, affordability, and durability.
PEX is often preferred for water lines due to its flexibility and resistance to freezing. It is lightweight and easy to install – typically only requiring a few basic tools such as a PEX fitting and a hand ratchet – and is not affected by erosion or corrosion.
While it is more expensive than PVC, its flexibility also makes it an ideal choice for tight spaces.
PVC is also an ideal material for water lines due its low cost and strength. It is less malleable than PEX, but it is easier to install as it can be cut or moulded into exact shapes. PVC is also resistant to corrosion, durable, and can handle higher temperatures than PEX.
In conclusion, both PEX or PVC are viable options for water lines and the best choice depends on the specific application and installation requirements. Consider consulting a professional plumber if you’re not sure which material to go with.
What pipe material would you recommend for the storm water line?
I would recommend a corrosion-resistant material such as UPVC, PVC-M, or HDPE for the storm water line. These materials resist corrosion, and are very durable, making them an excellent choice for long-term storm water lines.
They also do not require any special backfill or bedding, saving installation time and cost. UPVC is more flexible than concrete, allowing it to move if the ground shifts, while PVC-M and HDPE are very rigid and durable, making them perfect for large-diameter, deep-buried installations.
Additionally, these materials are all easy to install, require minimal maintenance, and are cost effective.
