Hose is very portable and easy to use. Hose is available in a variety of sizes and can be outfitted with the necessary fittings and connectors. While hose is expensive, it can be used in locations where other systems may be damaged by equipment or machinery. Being that hose is flexible, it can easily pass over and around obstacles.
Hose comes in two main types, suction and discharge. Suction hose contains an internal plastic or wire helix which helps to maintain its round shape, even under suction conditions. Discharge hose contains no helix, allowing it to lay flat, or be driven over without damage.
