A mainline pipe of 1 inch might be suitable for a small garden, but a large field requires 1-1/2 inch or 2 inch piping to ensure equal distribution. Additionally, some materials, such as PEX, are flexible and can be prone to collapsing if not properly supported, which can slightly reduce the actual water pipes diameter and restrict flow over time.

Conversely, if the velocity is too low, water can sit stagnant in the lines, increasing the risk of sediment buildup and bacterial growth. This loss is a significant factor when determining water pipes diameter over long runs.
Flow rate, measured in gallons per minute (GPM) or liters per second, is the volume of water moving through the system. For example, a nominal 1-inch PVC pipe has a smaller internal diameter than a nominal 1-inch copper pipe due to differences in wall thickness.

While this increases the material cost, it saves money in the long run by preventing pump failures, reducing noise, and ensuring consistent performance across the entire system. To maintain an optimal velocity, usually between 5 and 8 feet per second for cold water supply, the pipe diameter must be adjusted.
