Troubleshooting Tips for Airlock on the Little Giant APCP-1700 Series Pool Cover Pump


Owning a pool comes with its share of maintenance tasks, and ensuring your pool cover pump works efficiently is crucial for a clean and well-maintained pool. Little Giant's APCP-1700 Series is a popular choice for pool cover pumps, but like any equipment, it may encounter issues from time to time. One common problem is airlock, which can hinder the pump's performance. In this blog post, we'll delve into troubleshooting tips to address airlock issues in the Little Giant APCP-1700 Series Pool Cover Pump.

Understanding Airlock

Airlock occurs when air becomes trapped in the pump, preventing it from effectively moving water. This can lead to reduced or no water flow, affecting the pump's efficiency. Identifying and resolving airlock issues promptly is essential for maintaining a properly functioning pool cover pump.

Troubleshooting Steps:

  1. Check for Obstructions: Start by inspecting the pump for any debris or blockages that might be causing the airlock. Clean the intake and discharge ports to ensure there are no obstructions hindering water flow.
  2. Positioning Matters: Verify that the pump is correctly positioned in the pool. Ensure it is fully submerged in water, and the intake is not drawing in air. Proper positioning helps prevent air from entering the pump, minimizing the chances of airlock.
  3. Prime the Pump: If airlock persists, consider priming the pump. This involves filling the pump and suction line with water to eliminate air pockets. Follow the manufacturer's instructions for priming the APCP-1700 Series pump.
  4. Check for Leaks: Inspect the pump and its connections for any signs of leaks. Air may be entering the system through leaks, contributing to airlock issues. Tighten connections or replace damaged parts to resolve this issue.
  5. Adjust the Water Level: Ensure that the pool water level is adequate. A low water level can lead to air entering the pump, causing airlock. Maintain the water level within the recommended range to prevent this problem.
  6. Use a Check Valve: Consider installing a check valve on the discharge line. A check valve helps prevent water from flowing back into the pump when it is turned off, reducing the likelihood of air entering the system.

Proper maintenance and troubleshooting are essential for ensuring the optimal performance of your Little Giant APCP-1700 Series Pool Cover Pump. By following these troubleshooting tips, you can effectively address airlock issues and keep your pool cover pump running smoothly. Remember to consult the manufacturer's manual for specific guidance and always prioritize safety when working with pool equipment. A well-maintained pool cover pump contributes to a clean and enjoyable swimming experience.
