You can connect a suction hose to your water pump, so you can vacuum water from a rain barrel, pond, or ditch. Thanks to the check valve, the water flows 1 way so the hose suctions water faster. The filter blocks dirt and protects your garden pump or irrigation pump from damage. You can use a short hose for water sources nearby, such as a pond or a rain barrel. With a long hose, you can easily extract water from a ditch further away. Choose a length that suits your usage.
