PVC Schedule 40 Pipes and Fittings: Understanding the Differences and Uses of DWV, Potable, and Pressurized Systems

PVC Schedule 40 pipes and fittings are some of the most commonly used materials for plumbing and construction projects because they are durable, versatile, and cost-effective. However, there are different types of PVC pipes and fittings designed for specific uses, such as DWV (drain-waste-vent), potable (drinking water), and pressurized systems.


Understanding the differences between these systems is crucial for anyone who works with PVC pipes and fittings. In this blog post, we will explain the differences between DWV, potable, and pressurized systems, their unique features, and the recommended applications for each type of PVC Schedule 40 pipes and fittings.


Whether you are a seasoned plumber or a DIY enthusiast, this guide will help you choose the right PVC pipes and fittings for your next project.


Introduction to PVC Schedule 40 Pipes and Fittings

Make Sure You Use The Correct Type of PVC!

PVC Schedule 40 pipes and fittings are a popular choice for plumbing and piping systems because they are durable, affordable, and easy to install. These pipes and fittings are made from polyvinyl chloride, a strong and lightweight plastic material that can withstand high pressure and temperature fluctuations.

The term "schedule" refers to the thickness of the pipe wall, with Schedule 40 pipes having a thicker wall than Schedule 80 pipes.

PVC Schedule 40 pipes and fittings are available in three different types: DWV (drain-waste-vent), potable (drinking water), and pressurized (for water under pressure). Each of these types has different uses and requirements, and it is important to understand the differences between them to select the right type for your project.

In this article, we will explore the different types of PVC Schedule 40 pipes and fittings and their uses to help you make an informed decision for your plumbing and piping needs.

DWV Systems: Features, Applications, and Recommended Uses

DWV - Drain, Waste, and Vent PVC Pipes

DWV stands for Drain Waste Vent, and this type of system is designed to handle waste and sewage.


DWV systems are not meant for pressurized water or potable water, and they should not be used for such applications. The pipes used in a DWV system are typically made of PVC Schedule 40, and they come in a variety of sizes to accommodate different types of waste and sewage.


The most common application for DWV systems is in residential and commercial buildings, where they are used to remove waste and sewage from toilets, sinks, and showers. DWV systems are also used in industrial and agricultural settings to handle waste and wastewater.


One of the benefits of using a DWV system is that it is relatively easy to install and maintain. The pipes are lightweight and easy to work with, and they are also resistant to corrosion and chemical damage.


DWV systems are also designed to handle a wide range of temperatures and can operate in both hot and cold environments. When installing a DWV system, it is important to follow local building codes and regulations. The system should be properly vented to prevent the buildup of gases, and it should be installed at a slope to ensure proper drainage.


It is also recommended to use PVC Schedule 40 pipes and fittings that are specifically designed for DWV applications.


In summary, DWV systems are an essential part of any building's plumbing infrastructure. They are designed to handle waste and sewage and should not be used for pressurized water or potable water. PVC Schedule 40 pipes and fittings are commonly used in DWV systems due to their durability, ease of installation, and resistance to corrosion and chemical damage.

Potable Systems: Features, Applications, and Recommended Uses

OK, So You Don't Need A Hard Hat For Plumbing 😁

Potable PVC systems are designed for the purpose of carrying drinking water.


These systems usually have a white or light blue color and are marked with the NSF-PW or NSF-61 certification label. Potable PVC pipes and fittings are usually made from a higher grade of material that is safe for drinking water.


Potable systems are often used in residential plumbing and municipal water systems. These pipes and fittings are durable and long-lasting, making them ideal for outdoor use. They are resistant to corrosion, rust, and chemicals, which helps to prolong their lifespan.


Potable systems are also easy to install and require minimal maintenance. They are compatible with a wide range of fittings, making them the perfect choice for those who want to do their own plumbing work.


Some common applications for potable PVC systems include water supply lines, irrigation systems, and swimming pools. Potable PVC systems are safe and reliable, making them the perfect choice for anyone who wants a reliable and long-lasting plumbing system that can provide safe drinking water to their home or business.

Pressurized Systems: Features, Applications, and Recommended Uses


Pressurized PVC Schedule 40 pipes and fittings are designed to handle pressurized liquids such as water and air.


These pipes are made from a strong and durable material, making them perfect for applications that require high pressure and flow rates.


Some of the key features of pressurized PVC Schedule 40 pipes and fittings include their ability to withstand high pressure levels, resistance to corrosion and chemical damage, and their ability to handle high temperatures. Some of the most common applications for pressurized PVC


Schedule 40 pipes and fittings include irrigation, swimming pool installations, and water supply systems.


These pipes are also ideal for use in industrial applications, such as chemical processing plants, where the material's durability and resistance to chemicals are essential. When selecting pressurized PVC Schedule 40 pipes and fittings, it is important to consider the pipe's diameter, wall thickness, and pressure rating. The diameter and wall thickness determine the pipe's strength and ability to handle pressure, while the pressure rating indicates the maximum pressure that the pipe can withstand.


It is also important to ensure that the fittings used with the pipes are compatible with the pressurized system's application.


Overall, pressurized PVC Schedule 40 pipes and fittings are an excellent choice for a wide range of applications that require high pressure and flow rates. Whether you are looking to install a new irrigation system or need a pipe for your industrial application, pressurized PVC Schedule 40 pipes and fittings are a reliable and durable option that you can trust.

My Patent Pending Homemade Water Filter Uses Pressurized, Potable, Schedule 40 Parts and Pieces


Almost 10 years ago when my husband and I invented a Homemade Well Water Filter, we knew NOTHING about PVC.


We thought we did - but we didn't.


Our first version of our water filter invention, had non-pressurized pvc, DWV PVC, and I'm sure it had a dash of non-potable PVC thrown in for good measure.


Learn from out mistakes in my course to build a safe, efficient, and Patent Pending Homemade Well Water Filter!
