Introduction
Thank you for choosing the DEKOPRO 1/2HP 400W Submersible Sump Pump. This manual provides essential information for the safe and efficient use of your pump. Please read these instructions carefully before installation and operation, and retain them for future reference.
This pump is designed for draining water from various applications such as basements, swimming pools, garden ponds, and flooded areas. Its robust construction and automatic float switch ensure reliable performance.
Safety Information
WARNING: Failure to follow these safety instructions may result in electric shock, fire, serious injury, or death.
- Always disconnect the pump from the power supply before handling, cleaning, or performing any maintenance.
- Ensure the power supply voltage matches the pump's specifications (110 Volts).
- Do not operate the pump with a damaged power cord or plug. If damaged, it must be replaced by the manufacturer or a qualified service agent.
- Never lift or carry the pump by its power cord. Use the integrated handle.
- This pump is designed for water only. Do not use it for flammable, corrosive, or explosive liquids.
- Keep children and unauthorized persons away from the operating area.
- Ensure the pump is fully submerged during operation to prevent dry running and overheating. The thermal overload protection will activate if the pump overheats.
- Use a Ground Fault Circuit Interrupter (GFCI) for all electrical connections to prevent electric shock.
Product Overview
The DEKOPRO submersible sump pump features a robust design for efficient water removal. Key components are illustrated below:

Key Features:
- Powerful Motor: 400 Watt, 1/2 HP motor capable of moving up to 1981 Gallons Per Hour (7500 Liters Per Hour).
- Automatic Float Switch: Automatically starts when water level rises above 4.7 inches and disconnects power when water level falls below 4.7 inches. This prevents dry running and protects the motor.
- Durable Construction: Made from thermoplastic composite material, resisting corrosion and ensuring long-term durability.
- Thermal Overload Protection: Integrated protection system to prevent motor damage from overheating.
- Multi-Outlet Size: Compatible with 1-inch, 1.25-inch, and 1.5-inch hoses for versatile application.
- Solids Handling: Capable of passing solids up to 1/2 inch in diameter.
Setup
- Attach Discharge Hose:
Select the appropriate hose adapter (1", 1.25", or 1.5") based on your desired flow rate and hose size. A larger diameter hose will allow for a higher flow rate. Screw the chosen adapter onto the pump's output port. Connect your discharge hose securely to the adapter.
Figure 2: Various hose adapters (1", 1.25", 1.5") provided for connecting to the pump's discharge port.
Figure 3: Illustration of how the hose adapter components are assembled and attached to the pump.
- Position the Pump:
Place the pump on a stable, level surface in the area to be drained. Ensure the water suction port is clear of obstructions. The pump's higher base design helps prevent debris collection.
- Float Switch Adjustment:
The float switch controls the automatic on/off function. Ensure the float switch can move freely without obstruction. The pump will activate when the float rises to approximately 4.7 inches and deactivate when it drops below this level. Adjust the cable length of the float switch if necessary to achieve the desired on/off water levels, ensuring it does not get tangled.
- Power Connection:
Connect the pump's power cord to a grounded 110 Volt outlet protected by a Ground Fault Circuit Interrupter (GFCI). Do not use extension cords unless absolutely necessary, and ensure any extension cord is rated for outdoor use and appropriate amperage.

Operating Instructions
- Submerge the Pump:
Carefully lower the pump into the water. Ensure it is fully submerged and resting on a stable surface. The pump should not be suspended by its power cord or discharge hose.

- Automatic Operation:
Once plugged in and submerged, the pump will automatically start when the water level rises sufficiently to lift the float switch. It will continue to pump until the water level drops, causing the float switch to lower and turn the pump off.
- Manual Operation (if applicable):
If you need to operate the pump manually, you can hold the float switch in the "up" position. However, ensure the pump remains fully submerged to prevent dry running. For continuous manual operation, it is recommended to monitor the water level closely.
- Monitoring:
Periodically check the pump's operation and the discharge path to ensure water is flowing freely and there are no blockages.
Maintenance
Regular maintenance ensures the longevity and efficient operation of your pump.
- Cleaning: After each use, especially when pumping dirty water, rinse the pump thoroughly with clean water. Remove any debris that may have accumulated around the suction inlet or float switch.
- Inspect Power Cord and Plug: Regularly check the power cord and plug for any signs of damage, cuts, or fraying. Do not use the pump if any damage is found.
- Check Float Switch: Ensure the float switch moves freely and is not obstructed by debris. A stuck float switch can prevent the pump from operating automatically.
- Storage: When not in use for extended periods, clean the pump, drain all water, and store it in a dry, frost-free location.
Troubleshooting
Refer to the following table for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start. | No power supply; Float switch stuck in "off" position; Thermal overload activated. | Check power connection and GFCI; Ensure float switch moves freely; Disconnect power, allow pump to cool for 15-30 minutes, then reconnect. |
| Pump runs but does not pump water. | Air lock; Suction inlet blocked; Discharge hose kinked or blocked; Water level too low. | Lift and lower pump slightly to release air; Clear debris from suction inlet; Check and clear discharge hose; Ensure pump is fully submerged. |
| Pump cycles on and off too frequently. | Float switch cable too short; Water level fluctuating rapidly. | Adjust float switch cable length to allow for greater water level differential; Check for external factors causing rapid water level changes. |
| Reduced flow rate. | Partial blockage in suction or discharge; Incorrect hose diameter; Pump wear. | Clean suction inlet and discharge hose; Ensure appropriate hose diameter is used (larger for higher flow); If pump is old, consider replacement. |
