Question: 1 / 400

What is the minimum water pressure required to operate a sprinkler head system?

5 psi

10 psi

7 psi

The minimum water pressure required to operate a sprinkler head system is typically around 7 psi. This pressure is essential for ensuring that the sprinkler heads can distribute water effectively and uniformly across the intended area. At this pressure, the system is capable of delivering water with enough force to achieve the necessary coverage, allowing for proper irrigation and effective application of water.

A pressure lower than this threshold may result in inadequate performance, such as insufficient spray distance or coverage, leading to dry spots in the area being irrigated. Moreover, different sprinkler heads may have varying requirements, but 7 psi serves as a general baseline for many conventional systems. Understanding these specifications is crucial for anyone involved in installing or maintaining irrigation systems, as it affects the overall effectiveness of the watering system.
