What is one reason for having a pressure regulator in a system?

Having a pressure regulator in an irrigation system is essential for reducing incoming pressure to a manageable level. Many water sources, such as municipal supplies or water tanks, can deliver water at pressures that are too high for irrigation systems to operate efficiently and effectively. High pressure can lead to over-spray, misting, or excessive water usage, which ultimately affects the system's ability to apply the correct amount of water to plants.

By installing a pressure regulator, the system can maintain the optimal pressure needed for efficient operation, ensuring that water is applied uniformly and at the right rate. This helps in promoting healthy plant growth while conserving water resources. Without this regulation, the potential for damage to the irrigation components increases, making the system less reliable and potentially leading to increased maintenance costs or system failure.
