When it comes to plumbing projects, choosing the right pipe size is one of the most important factors to consider. PEX pipes have become a popular choice for plumbing applications because of their flexibility, durability and cost-effectiveness. Whether you are installing a new water line or replacing old pipes, understanding how to measure PEX pipes properly helps ensure a smooth installation and efficient water flow.
With larger PEX pipe sizes ranging from 1/2 inch to 3 inches, the commercial industry is also switching to PEX due to the installation efficiency. In this article, we’ll help you understand more about how to choose the suitable sizes and types of PEX pipes for your application.

Why Should I Use PEX pipes?
PEX pipes have become one of the most popular types in the plumbing industry due to their superior durability, flexibility and ease of installation. Compared to traditional materials like copper or PVC piping, installing PEX doesn’t require complicated techniques like soldering. PEX-A pipes are the most flexible among other types, which has made them suitable to be bent around corners and obstacles, reducing the need for additional fittings and minimising potential leak points.
PEX pipes also have various types and sizes for different projects, such as 1-inch PEX for residential home supply. Using a continuous length like a 1-inch PEX 100 ft roll allows you to install a main water supply wither fewer connections needed. All types of PEX pipes, PEX-A, PEX-B and PEX-C, are resistant to corrosion and freezing, making them long-lasting solutions for both hot and cold water lines. In general, PEX pipes are an efficient, cost-effective, flexible and durable solution that meets most of the modern plumbing standards. They are also a DIY-friendly material for those who are interested in doing the plumbing themselves.

PEX Pipe Sizes
PEX pipes come in a variety of sizes to accommodate different plumbing needs for both small fixtures and large main supply lines. The most commonly used diameters in residential and commercial plumbing include 3/8 inch, 1/2 inch, 3/4 inch and 1 inch PEX pipe. Each size of PEX pipe serves different purposes to maximise the performance of the piping system.
3/8 inch PEX pipes are typically used for short runs to individual fixtures, like a single faucet. 1/2-inch PEX pipes are the most common choice for branch lines or sub-lines that serve water applications like sinks, toilets and showers. 3/4 inch PEX pipes work great as a main water line for smaller homes or a supply line feeding multiple fixtures for a more stable performance. 1-inch PEX tubing is ideal for high-volume applications, such as main water lines for bigger houses, long pipe runs like radiant floor heating, or supplying water to multiple bathrooms and laundry simultaneously.
Choosing the right size PEX pipes is crucial for maintaining stable and efficient water pressure and flow. For example, suppose you are running a new main water line from the street to your home. In that case, a 1-inch PEX underground water line is a solid choice due to its durability and capacity. In short, the size of your PEX pipe will have a direct impact on your plumbing system’s performance, so whether you are installing a full piping system or making a small repair, it’s worth taking time to plan accordingly.

PEX Pipe Thickness
PEX pipes come in different types and thicknesses. The process of the three main types of PEX pipes has made them have different thickness, durability and flexibility. The difference has given these types of pipes various characteristics and usages. If you would like to learn more about the differences between PEX-A, PEX-B and PEX-C pipes, check out our newest article here.
PEX-A pipes are the most flexible type. They are created to have a high degree of cross-linking, which gives them superior flexibility and resilience to freezing or bursting. PEX-A is a good choice for cold-weather climates or installations that require a lot of bending.
PEX-B is typically the type that has the thickest wall compared to its outer diameter. As this kind of pipe is stiffer and less flexible, manufacturers typically produce it with slightly thicker walls to achieve better pressure ratings than PEX-A pipes. PEX-B pipes are often the most cost-effective option for the majority of plumbing systems. Although they are slightly more difficult to work with in tight spaces because of their lower flexibility, their higher resistance to pressure has made them a suitable option for those who are looking for a more budget-friendly material.
The wall thickness of PEX pipes determines the pipe’s pressure rating and resistance to damage. In general, thicker walls mean that the pipes can handle higher water pressure without deforming. This is especially important if you are considering using PEX pipes as a main water supply line or an underground water line, as the durability and strength of pipes are critical for these applications. For all EFIELD PEX pipes, we’ve included this feature for you to compare. No matter which thickness you choose, PEX pipe offers excellent resistance to scale, chlorine, corrosion and leaks, making it a top choice for modern plumbing systems.
Conclusion
Measuring PEX pipe accurately is one of the most important steps to ensure an efficient and stable plumbing project. From choosing the right PEX pipe size to selecting the appropriate thickness and length, every factor contributes to a reliable and long-lasting installation. Whether you are installing a 1-inch PEX underground water line, upgrading your home’s main supply with a 1-inch PEX pipe or making quick fixes with 10 ft pipe cuts, proper planning ensures efficiency and performance.
