What is the reason for not mixing drip emitters and bubblers on the same valve?

• A. They require different pressure settings
• B. They operate at different temperatures
• C. They have varying flow rates
• D. They are incompatible with each other

Answer: (A)

The reason for not mixing drip emitters and bubblers on the same valve is primarily due to their different pressure requirements. Drip emitters are designed to work efficiently at lower pressures, enabling precise water delivery to individual plants or soil zones. They are generally calibrated to function optimally at a specific range of pressure, which allows for effective water distribution while minimizing waste.

On the other hand, bubblers typically require higher pressure to operate correctly. They are designed to release a larger volume of water quickly, which is best suited for areas that need saturation over a broader space or where water needs to pond around root zones.

When these two irrigation components are combined on the same valve, the differing pressure settings can cause inefficiencies and inconsistencies in watering performance. The emitters may not release water properly, while the bubblers could either underperform or flood the area, leading to either drought stress for the plants served by emitters or overwatering for those near bubblers. This mismatch can ultimately undermine the effectiveness of the irrigation system, making it less efficient in conserving water and providing adequate hydration to plants.
