Drip irrigation systems require lower pressure to function correctly, making the use of pressure regulators necessary to avoid damage from high water pressure, such as burst lines and blown emitters. Sprinkler Warehouse recommends incorporating a pressure regulator to ensure efficient and effective performance of drip emitters, as too much pressure can harm the system. These regulators adjust incoming high water pressure to a level suitable for the drip system, with their operation kicking in only after a certain flow rate is met. We offer a variety of pressure regulators including options for low, medium, and high flow, tailored to meet any system's needs. It's important to install these regulators after valves or shutoffs to prevent damage, following the product guidelines for constant pressure situations.
