10 Methods Of How to Find Irrigation Lines

In order to locate irrigation lines, there are several methods you can use. Such as:

1. Use an Edger or a Metal Detector

One of the most common methods for locating irrigation lines is using an edger or a metal detector. It’s important to note that the edger’s blade must be sharp enough to make contact with the line, otherwise, it won’t work. Similarly, if you use a metal detector, make sure its sensitivity setting is adjusted appropriately.

2. Look for Spikes in the Ground

Another method to use is looking for spikes in the ground. As sprinkler systems are installed, spikes are driven into the ground and they can help you find where irrigation lines run between them.

3. Digging and Excavation

Digging or excavation may be required if you cannot locate your irrigation lines with the methods mentioned above. Although this may take more time and effort, it is also an effective way to find irrigation lines.
