Suction Hose is a specific type of hose used in drafting operations when using a vacuum to draw water from a portable water tank, pool, or another static water source. It is built to withstand vacuum, rather than pressure, abrasion, and heat.

The suction pipes are designed to sustain different pressures as per the different water sources. In Irrigation the regular PVC pipes are designed for the limited velocity (1.5 m/s) to have a laminar flow & hence they are used for ground operations.
