True or False: Suction piping should be one pipe size larger than the pump intake.

Suction piping being one pipe size larger than the pump intake is indeed considered a best practice in many irrigation systems. This approach helps to minimize friction losses and ensures that the pump can draw in water more efficiently, especially when dealing with increases in flow demand or when the source of water has variable characteristics. A larger suction pipe reduces the chances of cavitation and minimizes pressure drops as water flows into the pump. This is particularly important in maintaining optimal pump performance and longevity.

In certain situations such as when a specific pump type or unique system design is involved, the requirements may vary. However, as a general rule, especially for most standard pump operations, utilizing a suction pipe that is one size larger is advisable. This practice enhances the overall efficacy of the irrigation system and helps prevent common problems associated with inadequate suction configurations.
