Which hose size is superior to deliver a large amount of water with very little friction loss?

• A. 2-inch hose
• B. 3-inch hose
• C. 5-inch (LDH)
• D. 4-inch hose

Answer: (C)

When moving a large volume of water, reducing friction loss is crucial. Friction loss rises with flow velocity and the length of the hose, so using a larger diameter hose helps keep the loss down. The 5-inch LDH hose is designed specifically for high-volume supply lines; its large bore allows much more water to pass with far less friction per foot than smaller hoses. This means you can deliver a big volume without needing excessive pump pressure, which is exactly what you want for sustained water supply. The smaller options—2-inch, 3-inch, and even 4-inch—have smaller diameters, so at the same flow they incur more friction loss and require higher pressure to achieve the same GPM.
