Gardena suction filter with check valve 19/25 mm

What does the Gardena suction filter with check valve do?

The Gardena suction filter with check valve protects your garden pump or domestic water system from dirt particles drawn from wells, cisterns or water butts. It also stops water flowing back into the line after the pump switches off.

The filter sits at the end of the suction hose and holds back coarse dirt such as sand, leaves and small particles. This helps extend the service life of your pump and reduces operating faults.

Technical data and compatible hose sizes

The Gardena suction filter with check valve 1728-20 is suitable for two common hose diameters:

• For suction hoses with 19 mm diameter (3/4 inch)
• For suction hoses with 25 mm diameter (1 inch)

The integrated check valve keeps the suction line filled after switch-off. This makes the next pump start easier and shortens the priming time.

What advantages does the suction filter offer?

With this suction filter you upgrade pumps and suction hoses to a reliable system for garden and household water use. You benefit in daily operation as follows:

• Protects the pump from coarse dirt particles in the water
• Less wear thanks to reduced load on pump components
• Faster pump start-up due to integrated check valve
• Simple installation at the end of the suction hose
• Suitable for irrigation and water extraction from wells and cisterns

Who is the Gardena suction filter suitable for?

The suction filter is suitable for garden owners who pump water from wells, cisterns or rainwater tanks. It fits many Gardena pumps and suction hoses with 19 mm or 25 mm diameter.

If you want to protect your pump reliably against dirt and make re-priming easier, this filter is a practical addition to your system.

Application and installation tips

Install the suction filter at the lower end of the suction hose that hangs in the water. Make sure the filter is fully submerged but does not rest in sludge on the bottom. This keeps the filter surface clear so that water can flow freely.

Check the filter regularly for contamination and clean it when necessary. This maintains the flow rate and helps your pump run smoothly and evenly.
