Final answer:
The maximum downstream pressure from a pump serving a gray water irrigation field shall not exceed a certain value to ensure the system operates efficiently and safely.
Step-by-step explanation:
The maximum downstream pressure from a pump serving a gray water irrigation field shall not exceed a certain value to ensure the system operates efficiently and safely. This pressure limit is typically expressed in pounds per square inch (psi). The specific maximum pressure may vary depending on the requirements of the irrigation system and the components being used.
For example, some common maximum pressure limits for irrigation systems range from 40 psi to 80 psi. These limits are based on factors such as the type of spray or drip irrigation being used, the soil conditions, and the water source pressure. To determine the maximum downstream pressure for a specific gray water irrigation system, it is important to refer to the manufacturer's guidelines or consult a professional in the field.
