uxcell 4GPH Pressure Compensating Drip Emitters - 16L/H Garden Irrigation Drippers with Barbed Hose Connectors (15pcs, Black & Blue) - Perfect for Lawn, Flower Beds & Vegetable Garden Watering Systems

How Much Water Pressure Do You Need for Drip Irrigation? A typical drip irrigation system needs about 25 pounds per square inch (psi) of water pressure to function optimally, but many emitters rated at 25 psi will work well at pressures as low as 15 psi. What is Pressure Compensating? Pressure Compensating (PC) is an emitter that maintains the same output at varying water inlet pressures. Therefore, PC drip emitters compensate for uneven terrain, length of supply tube and varying inlet flows. PC drippers facilitate more controlled watering, as each drip emitter performs to a preset flow rate (e.g. 1 gallon per hour), allowing water emitted over a length of time to be easily calculated. This ensures more efficient watering, reducing the risk of overwater or underwater. Material: Plastic Flow Rate: 4GPH Barb Diameter: 6mm O.D. Nozzle Diameter: 4mm I.D.
