Reduced water output from the pond pump can be due to:

• Dirt buildup at the housing. Clean the pump parts and place the pump not directly in the bottom mud, but on an elevation (of stones).
• Obstruction of outflow. Use as large a hose diameter as possible, cut off the unused portion of the hose grommet and avoid pinching off the water flow. If the water flow has to overcome a height, the net yield decreases.
• Contamination or wear on rotor. Open the pump and remove or replace the dirt at the rotor. Easily order new parts online at www.vijverproducten.shop.
