Most common issues with shallow well pumps?

Clogging Issues and Precautions

Clogging is a leading cause of shallow well pump failure. To prevent clogging, regularly inspect and clean the pump inlet screen, which should be at least 1/4 inch mesh size to catch debris. Install a pre-filter or a sediment trap in front of the pump to catch larger particles. Replace the inlet screen every 6 months or as recommended by the manufacturer.

Installation and Setup Issues

Improper installation is another common issue with shallow well pumps. Ensure the pump is installed at the correct depth, typically 10-20 feet below the water table. Verify the pump is level and securely fastened to the well casing. Use a level and a plumb bob to ensure the pump is properly aligned. Follow the manufacturer’s guidelines for installation and setup to avoid costly mistakes.

Flow Rate and Horsepower Concerns

Inadequate flow rate is another common issue with shallow well pumps. Check the flow rate of your pump against your needs. A general rule of thumb is to use a pump with a flow rate of at least 10 gallons per minute (GPM) for a single-family home. Ensure the pump has sufficient horsepower to overcome the static head of your well. A typical shallow well pump requires 1/2 to 1 HP for depths up to 30 feet. Always consult the manufacturer’s recommendations for specific horsepower requirements.
