But there’s good news—selecting the right pipe material for your irrigation system can dramatically improve efficiency, longevity, and performance while reducing maintenance headaches. In this comprehensive guide, we’ll walk you through everything you need to know about choosing the best pipes for irrigation system applications in .
Before diving into specific materials, it’s crucial to understand the key factors that should influence your pipe material selection:
By evaluating these factors first, you’ll be in a much better position to select the ideal pipe material for your specific irrigation needs.
When choosing the best type of pipe for irrigation, you’ll encounter several common materials, each with distinct advantages:
Polyvinyl chloride (PVC) pipes dominate the irrigation market, and for good reason. These rigid white pipes come in various pressure ratings and sizes to accommodate different system requirements.
Advantages of PVC pipes:
Disadvantages:
For high-pressure applications, PVC high-pressure valves are essential components to pair with your PVC pipes. These valves help regulate water flow and pressure throughout your irrigation system.
When selecting PVC pipes, quality matters significantly. Learn how to check PVC pipe quality to ensure you’re investing in durable materials that will stand the test of time.
High-Density Polyethylene (HDPE) pipes offer outstanding flexibility and durability, making them increasingly popular for irrigation applications.
Advantages of HDPE pipes:
Disadvantages:
For large-scale irrigation projects, HDPE large diameter pipe options provide excellent flow rates and pressure handling. These pipes undergo rigorous testing to ensure reliability—learn more about different HDPE pipes testing methods to understand quality assurance.
Polypropylene Random Copolymer (PPR) pipes are less common in traditional irrigation but excel in specialized applications, particularly where hot water might be involved.
Advantages of PPR pipes:
Disadvantages:
Understanding why PPR pipe is used and exploring PPR pipe fitting types can help determine if this material is suitable for your specialized irrigation needs. For hot water applications in greenhouse irrigation, PPR is often the preferred choice—learn more about which pipe is used for hot water supply.

This comparison highlights why there’s no one-size-fits-all answer to how to choose the best pipes for irrigation system projects. Your specific circumstances will determine the ideal material.
Once you’ve selected your pipe material, determining the correct size is crucial for system performance. Pipe sizing depends on:
For irrigation systems, common sizes range from ½” for drip systems to 6″ or larger for major agricultural operations. The standard sizes of PVC pipe article provides detailed information on available dimensions.
When dealing with specific fitting sizes, understanding thread specifications is important—for example, learning what thread size is 3/4 PVC fitting can prevent compatibility issues during installation.
Pressure rating is a critical specification when selecting pipes for irrigation. The two most common ratings are PN10 and PN16, which indicate the maximum working pressure the pipe can handle.
Understanding the difference between PN10 and PN16 helps ensure your system operates safely within pressure limitations. Generally, residential irrigation systems can function well with PN10 pipes, while commercial or high-pressure applications might require PN16.
If your system experiences pressure issues, explore solutions for how to increase water pressure in a pipe to optimize performance without replacing all pipes.

While initial cost often drives material selection, considering long-term value provides a more accurate picture:
When calculating total ownership cost, consider:
A large commercial development in Dubai implemented a hybrid system using:
The project demonstrated 40% water savings compared to traditional systems while requiring minimal maintenance over five years. The initial investment was 15% higher than a pure PVC system but achieved ROI within three years through water and maintenance savings.
A 50-acre farm switched from aluminum pipes to HDPE, resulting in:
Selecting the best pipe material for your irrigation system requires balancing multiple factors including climate, pressure requirements, budget, and intended use. Here’s a simplified decision framework:
Remember that a high-quality irrigation system often incorporates multiple materials—using the best pipe for each specific section rather than a one-material approach.

To select the right tubing for your project, you first have to know what type of tubing you need. Low-pressure tubing, for drip irrigation, can be broken down into three categories: mainline tubing, micro-tubing, and dripline tubing. Before describing the use of each type of tubing, it is important to first understand the basic rules and limitations of each type. Not adhering to these rules can result in a poorly functioning drip irrigation system.
Regardless of the type of tubing selected for your project, there are two pieces of information that are critical when selecting tubing: run length and total flow rate. For example, what is the length your longest run of tubing needs to be? How many gallons per hour will your system be requiring? To choose the right tubing for your project, both factors need to be considered, but at this moment, let’s look at each separately.
Maximum run length is the longest length for which a certain size of tubing can maintain equal pressure. If the maximum run length is exceeded for a size of tubing, then the pressure supplied to each dripper or watering device will vary, and this can cause strange things to happen (e.g., water shooting out of drippers, no water coming out, etc.). Maximum run length varies for each size of tubing, so knowing how far you need to run tubing before ordering helps to make sure you order the right size for your project.
When selecting the right tubing size for your project, maximum run length is important, but the maximum number of gallons per hour (GPH) that a size of tubing can supply needs to be considered as well. Each size of tubing can only supply a certain number of gallons per hour before too much pressure loss begins to occur. To find the gallons per hour that you need in your system, you simply add up the output of all the watering devices. For example, if your system uses 40 .5-GPH drippers, 20 1-GPH drippers, and 2 adjustable drippers at 10 GPH, the total GPH used is:
Add the total for each dripper type (20 + 20 + 20) to give a grand total of 60 GPH
Once you know both of these factors, then it is easy to select the size tubing that best fits your project needs. Take, for example, a project that has a maximum run length of 20 feet and a flow requirement of 60 GPH. What tubing could be used? Take a look at this chart. PLEASE NOTE this chart is in reference to your mainline:
Tubing SizeMaximum Run LengthMaximum GPH Supplied1/4"30 feet30 GPH1/2"200 feet200 GPH3/4"480 feet480 GPH1"960 feet960 GPHYou can see that the run length allows for all sizes of tubing to be used, but because the total GPH needed is 60, this eliminates ¼” tubing because 60 GPH is more than double what ¼” tubing can supply (30 GPH). If ¼” tubing were used for this system, it would not function properly.
Note: If you think you may want to expand your system in the future, it is a good idea to start with one tubing size larger than your run length and gallons per hour require, in order to give you the flexibility to add to your system in the future.
Frequently Asked Questions About Tubing:
Mainline tubing (a.k.a. supply line tubing) acts as the water supply for your system. Mainline tubing starts at a water source and is then run as needed. Selecting the right size mainline tubing is important. To choose the right size mainline tubing, match your maximum run length and total gallons per hour needed with the chart above. Once the mainline is laid out in your system, water devices can be inserted directly into the mainline tubing or adapters can be inserted to run micro tubing, drip tape, or dripline away from the mainline tubing to the plants to be watered.
Micro-tubing is commonly used to describe ¼” tubing. It can be used as mainline tubing, but remember that it cannot be over 30 feet in length or supply more than 30 GPH. This works well for small patio areas, but beyond that micro-tubing is often used to take drippers or other watering devices from the mainline tubing to the plant to apply water directly to the root zone. A hole punch is used to create a hole in the mainline tubing (½” or greater) where one end of a connector is inserted; the other is connected to a run of ¼” micro-tubing. Even though the micro-tubing is not being used as mainline tubing, it still can’t stretch more than 30 feet away from the mainline tubing. Micro-tubing comes in either poly or vinyl rolls. Below we’ll briefly describe the pros and cons of each.
When buying drip irrigation tubing, the micro-tubing (1/8" or 1/4") is the only one that requires you to decide between poly or vinyl. Vinyl tubing is softer than poly and thus is considered easier to work with. Poly tubing may be a bit stiffer at first, but it does have some benefits. It withstands UV rays very well and does not expand, as much, when heated. Many of our customers in the hotter southern states (Texas, Arizona, New Mexico, etc.) have reported that their vinyl tubing began to pop off of the fittings after about 2–3 years of use. Due to the additives to make vinyl tubing softer, it softens much more than poly in the heat of the sun. This can cause the tubing to slip off the fittings after prolonged exposure to the sun. Poly micro-tubing is much more resistant to expansion and therefore less likely to come off the fittings or drippers.
Unfortunately, in the drip irrigation industry, there are no industry standards regarding tubing. Drip irrigation tubing is considered nominally sized. What this means is that tubing products manufactured by different manufacturers will not necessarily be the same size, even if they both say, for example, half an inch (½”). When adding to an existing system, it’s important to know the manufacturer of your tubing as well as the inside and outside diameter of the tubing you want to add to. To find out more about compatibility, check out our compatibility guide.
A dripline is a tubing that has emitters embedded directly into the tubing at preset spacings and dripper flow rates. Dripline tubing can save a lot of time, as there is no need to insert drippers. You simply lay out your dripline and connect it to your system. Dripline is available in ½” and ¼” tubing sizes with a limited number of standardized emitter spacings and emitter flow rates.
Note: The maximum run lengths for the dripline still apply (¼” 30 feet & ½” 200 feet). Below is a chart of available driplines and common uses for each
