If you are looking for a solution to remove water from any equipment or place, a discharge hose will be the best option for you. It helps you to transport slurry, chemicals, fuels and other liquids. So in this guide, we will tell you what a discharge hose is, its various features, and types. Plus, you learn how to choose the right hose for your specific application.
What is a Discharge Hose?
A discharge hose is a flexible tube that is used to transfer fluids, slurries and other materials from one place to another. You can attach it to the outlet side of the pump to push water away from the drainage area. With the help of it, you can carry sewage, waste water, industrial chemicals and beverage products easily.
As discharge hose work under pressure, it is designed to handle this positive pressure. Some discharge hoses have reinforcement layers in their structure that prevent them from bursting. The material that is used in hose construction depends on the type of fluid they move, working pressure, and environment. Main materials that are used in discharge hose manufacturing are:
- Polyvinyl chloride (PVC)
- Rubber
- Polyurethane
- Nitrile (NBR) rubber
- Woven polyester fiber
- EPDM rubber
Features of Discharge Hose
You can use a discharge hose to move fluids under pressure from a pump or fluid source to a specific destination. It has various characteristics that are as follows.
| Properties | Explanation |
| Flexibility | Allow the hose to bend and move easily during fluid transfer. |
| Pressure Rating | Built to handle high working pressure, range from 30 to 150+ psi. |
| Reinforcement Layer | Reinforced with high tensile braided polyester or nylon to prevent bursting. |

| Temperature Range | Operate from -20°F to 180°F (-29°C to 82°C) |
| Weight & Portability | Lightweight makes the hose easy to handle, move and install. |
| Lay flat design | Allow some hoses to flat when not used, make storage and transport easy. |
| Diameter and length options | Different sizes help match the hose to the required flow rate and distance |
| Coupling compatibility | You can connect hose with pumps, valves and fittings using suitable couplings. |
How Does a Discharge Hose Work?
To drain water from a tank, reservoir or another source, you can use a discharge hose. For this process, it uses the positive pressure of the pump. With the help of it, the fluid transfers to the hose. The inner lining of the discharge hose produces less friction which helps to smooth flow of liquid. As a result, the pump maintains the high flow rate without overworking the motor.
Then, it transports water to your desired exit point such as storm drain, yard and irrigation system. However, some blue lay flat hoses are lightweight and flat. They become round tubes when filled with pressurized fluid. They also contain layers of synthetic fiber and textile cords that stop the hose from expanding too much under high internal pressure.
Types of Discharge Hose
Discharge hoses come in various forms on the base of material they transfer, material composition, pressure rating and structural design. You can choose one of them according to your specific needs.

- Flooded basement
- Excavations
- Swimming pool
- Flood control operations
- Drainage systems
Agriculture and Irrigation
As a farmer or landscaper, you can install discharge hose for your irrigation systems. It helps you to transfer large volumes of fluid from ponds and tanks to the field over long distances. In agriculture, you can use it for the following purposes.
- Crop irrigation
- Garden watering
- Greenhouse irrigation
- Landscape watering
- Water movement between tanks and reservoirs
Industrial Applications
The discharge hose is also useful in industries. You can use it to move liquids and fluid mixtures between equipment and processing areas. But for this process, you have to select a hose that is suitable for these products. It is helpful in:
- Wastewater transfer
- Slurry handling
- Oil and fuel transport
- Chemical transfer

How To Select Right Discharge Hose For Your Project?
To choose correct hose for your needs, you can consider the STAMPED guideline. You think that it is a simple word but each letter has a hidden meaning. For your facility, we explain them one by one.
1. Size
First of all, you must match the hose’s inner diameter (ID) to your pump’s discharge port. Make sure the length covers the distance without excessive slack. Plus, a too small hose can restrict fluid flow and cause pressure loss.
2. Temperature
Before buying discharge hose, you need to check its material (it can withstand weather conditions or not). You should select those hose which remain flexible in the cold and do not melt or weak in the heat.
3. Application
You should also consider the work environment. If you want to use a hose for flat and downhill water flow, blue lay flat hoses will be the best option. But for uphill, you must select the high rated brown lay flat hoses.
4. Medium (fluid)
If you want your discharge hose to work for a long time, you should identify the fluid that will be passed through the hose. For instance, to transfer clean water, chemicals, slurry or oil, you will choose a hose according to them.
5. Pressure
You also need to check the maximum working pressure of your system. The standard discharge hoses range from low pressure (30 – 80 psi) to medium pressure (150 psi). So, you can pick the hose according to your system pressure.
6. Ends
To fix hose on the outlet of the pump, you have to pick the correct size of clamps and connectors. They help you to seal the hose fitting properly. Always make sure the fitting material does not react with the fluid.
7. Delivery
You can also pick the best hose on the base of flow rate you want for your system. You must consider how far you need to move the fluid. The hose size and length should support the required fluid delivery.
Wrapping It Up
There is no doubt that discharge hose play an important role in various fields. With the help of it, you can easily remove excess water from your desired place. As a result, you do not need to carry a bucket to drain water. But for its efficient working, you have to purchase the right discharge hose which will be according to your system.
Commonly Asked Questions
What is the difference between suction and discharge hose?
The main difference between them is that a suction hose works under negative (vacuum) pressure. You can connect it to the inlet side of the hose to draw water from a source. While discharge hose attach to the outlet side of the pump to deliver fluid away from destination.
Can discharge hoses be used for drinking water?
No, you can not use standard or agricultural discharge hose for drinking water. Because it can leach harmful chemicals in the water. If you want to drink water from it, make sure it is specifically certified as food grade or not.
How to connect two discharge hoses?
To connect two discharge hoses for pool backwash, washing machine and sump pump, you will first choose a suitable coupler or adapter. Then, attach both ends of the hose to the coupler and tighten connection with hose clamps.
