What You'll Learn
Heat it up and mould it
To straighten plastic irrigation tubing, you can apply heat and mould the tubing into the desired shape. Here is a step-by-step guide:
First, decide on the heat source you will use. Some common options are a hairdryer, boiled water, or a heat gun. It is important to note that certain heat sources, like a heat gun, can change the physical properties of the tubing, making it more prone to breaking, cracking, or splitting. So, exercise caution and consider the tubing's proximity to other materials and your own safety when choosing a heat source.
Next, apply heat to the tubing evenly. Ensure that the heat is distributed over a large enough area to effectively straighten the desired section of tubing. For example, a dryer might be used for this purpose, as it provides heat over a larger surface area.
Once the tubing is heated sufficiently, carefully mould it into the desired shape. This is a crucial step, as it determines the final form of your tubing.
Finally, allow the tubing to cool while maintaining the desired shape. You can use cold water to speed up this process and lock in the new shape.

Insert a dowel inside the tubing
To straighten plastic irrigation tubing, one method is to insert a dowel inside the tubing. This method can be done by first ensuring that the tubing is clean and free of any debris. Next, identify any defects or damage that may hinder the straightening process. Choose an appropriately sized dowel that fits snugly inside the tubing. Insert the dowel into the tubing, taking care not to bend or kink the tubing during this process. Once the dowel is in place, heat the tubing gently using a heat gun on low heat or by placing it in an oven. Be cautious not to overheat the tubing, as it can be sensitive to heat. After heating, the tubing will become pliable and can be straightened by hand or with a straightening device. Hold the shape until it cools down and sets, then remove the dowel.
The dowel method provides a simple and effective way to straighten plastic irrigation tubing. It allows for better control and manipulation of the tubing during the straightening process. By inserting the dowel, you create a rigid structure within the tubing, making it easier to handle and guide into the desired shape. This technique is especially useful for longer lengths of tubing, as it provides stability and helps maintain the straight form while the plastic cools.
Additionally, the dowel aids in preventing kinks and bends in the tubing. Kinks can restrict flow and cause blockages, leading to maintenance issues. By using the dowel as a guide, you can achieve a smoother and straighter result. It helps to ensure that the tubing aligns correctly, avoiding errors in processes that rely on precise flow rates.
When selecting a dowel, consider using a material that can withstand heat without warping or transferring excessive heat to the plastic tubing. This will help maintain even heating and prevent damage to the tubing. It is also important to work in a well-ventilated area when using a heat gun to avoid inhaling fumes.
The process of straightening plastic irrigation tubing with a dowel is a straightforward task that can be completed with the right tools and techniques. By following these steps, you can effectively straighten the tubing, ensuring optimal performance and a neat appearance for your irrigation system.

Stretch it out in the sun
Stretching your plastic irrigation tubing in the sun is a great way to straighten it out, especially if you have a long length of tubing to work with. This method is simple and effective, and it can save you time and effort. Here's how to do it:
First, find a sunny spot in your yard or on your roof. The key is to find a space where your tubing can stretch out straight without any obstructions. If you have a 20-foot length of tubing, for example, you'll need a clear area that can accommodate that length. Place the tubing in the sun, ensuring it is straight and not coiled or bent.
The heat from the sun will gradually warm the plastic, making it more malleable. Depending on the weather conditions and the intensity of the sunlight, you may need to leave the tubing out for a day or two. Warmer temperatures and direct sunlight will speed up the process. For even better results, place the tubing on a dark surface, such as asphalt, which will absorb heat and help straighten the tubing faster.
You can also try this method on a smaller scale if you don't have access to outdoor space. Place the tubing near a window where it can soak up sunlight, or even on a sunny balcony or patio. Keep in mind that the tubing may need to be left out for a longer period if it is not receiving direct sunlight.
While this method is safe and effective, it is important to note that overexposure to sunlight and high temperatures can eventually degrade the plastic. Therefore, it is best to monitor the tubing and bring it indoors or into the shade once it has straightened to your desired level.
By following these steps, you can easily straighten your plastic irrigation tubing using the natural power of the sun, without the need for specialized tools or complex techniques.
