Metabo HWW 3500-25 G Pump F.A.Q.

What is the recommended procedure for priming the Metabo HWW 3500-25 G Pump?

To prime the Metabo HWW 3500-25 G Pump, first ensure the pump is turned off. Remove the priming plug and fill the pump housing with water until it overflows, then securely replace the plug. Ensure all connections are tight before turning the pump on.

How can I troubleshoot if the pump does not start?

Check if the power supply is active and the plug is properly connected. Ensure the motor reset button has not tripped. Inspect for any blown fuses or tripped circuit breakers. Confirm that the pressure switch is functional and properly set.

What maintenance steps should I take to ensure the pump operates efficiently?

Regularly inspect and clean the filter and suction lines. Check for any leaks in the connections and seals. Periodically lubricate moving parts according to the manufacturer's instructions and ensure the pump is stored in a dry environment.

How do I resolve issues with the pump losing pressure?

Inspect for leaks in the hose and connections. Check if the foot valve or check valve is clogged and clean if necessary. Ensure the pressure tank is not waterlogged and adjust the pressure settings to the recommended levels.

What should I do if the pump is making unusual noises?

Unusual noises can be caused by air trapped in the pump, cavitation, or worn bearings. Bleed the system to remove any air. Ensure the suction lift is not too high and inspect bearings for wear, replacing them if needed.

Can the Metabo HWW 3500-25 G Pump be used for drinking water applications?

The Metabo HWW 3500-25 G Pump is suitable for clean water applications. Ensure that all materials in contact with water are food-grade if used for drinking water to avoid contamination.

How do I adjust the pressure settings on the pump?

Adjust the pressure settings by turning the pressure switch adjustment nut. Increase pressure by turning it clockwise, and decrease pressure by turning it counterclockwise. Refer to the manual for specific pressure settings.

What is the correct way to store the pump during winter months?

Drain all water from the pump and system to prevent freezing. Store the pump in a dry, frost-free location. Consider using antifreeze products designed for pumps if they must remain connected.

How often should I inspect the pump for wear and tear?

It is recommended to inspect the pump every 3 to 6 months, depending on usage frequency. Look for signs of wear, corrosion, and check all seals and gaskets for integrity.

What could be the reason for the pump not delivering water despite running?

Ensure that the suction line is not blocked and the foot valve is functioning properly. Check for air leaks in the suction line and confirm that the pump is properly primed.
