Properly installing your underground well pump wire is just as important as choosing the right one. This guide will walk you through key installation tips and help you troubleshoot common issues to ensure your well system stays operational.
Well Cable
Key Installation Tips for Direct Burial
- Choose the Right Cable: Use a cable that is specifically rated for direct burial in wet locations. Our cables feature a robust PE/PVC jacket designed for this exact purpose, meeting strict UL standards.
- Dig a Proper Trench: The trench should be at least 18 inches deep to protect the cable from accidental damage and extreme temperatures.
- Avoid Sharp Turns: Lay the cable in a smooth, continuous line. Sharp bends can stress the conductors and outer jacket, compromising their integrity.
- Use Proper Splices: If splicing is necessary, use a waterproof, heat-shrinkable splice kit specifically designed for submersible pump wire. A poor splice is a common point of failure.
Common Well Pump Cable Issues & Troubleshooting
Symptom: Pump is not running.
- Potential Issue: A complete break in one or more conductors.
- Troubleshooting: Use a multimeter to check for continuity along the cable. This is a sign you need a replacement wire.
Symptom: Pump motor runs hot or trips breaker.
- Potential Issue: Voltage drop due to an undersized cable or a poor connection.
- Troubleshooting: Check the voltage at the control box and then at the pump terminals (if possible) to see if there's a significant drop. A voltage drop of more than 5% indicates an issue.
When to Replace Your Cable
If your well pump cable is old, damaged, or showing signs of insulation degradation, it's a huge safety risk and a potential source of future failure. Replacing it with a high-quality, certified cable is a small investment that protects your valuable pump and ensures the safety of your system.
