Discharge vs Suction Hose: Key Differences

You may need to buy one or both of these hoses for your work or may need to gather knowledge due to your profession. Whatever the reason is, the following explanations on the differences can enhance your knowledge about suction and discharge hoses:

Function

The water suction hose and the discharge hose function differently. A suction hose soaks water from a water source and transfers it to the pump. And then, the water is released to another source through the discharge hose. 

Purpose

If you want to take water out from a water source, you need to use the suction hose first. And when you want to spray or release the water, you will require a discharge hose.

Usage

Suction hoses are often used to empty lakes or ponds. Then when there is a necessity to remove water from a flooded area quickly, suction hoses are helpful. This hose also helps in conveying industrial chemicals to one place from another.

The most common usage of discharge hose is in fire services and in agriculture. Fire workers use a discharge hose to spray water from the tank to the fire. People also use discharge hoses to spray water on the cornfield.

Weight

Usually, suction hoses are lightweight for convenient usage. Discharge hoses may feel a little bulky compared to suction hoses.

Durability

Both of these hoses are highly durable in their own field. But when you keep them side by side, discharge hoses can withstand more pressure or adverse environment compared to suction hoses.

Price

Are you planning to buy these hoses? Then you may want to know about their cost. Suction hoses are a little bit expensive, whereas discharge hoses come at a lower price.
