Quick Answer
When choosing a backup pump for a jet pump system, consider a submersible pump with the right horsepower and flow rate for your specific water demand, and ensure it's compatible with your existing system's voltage and pressure requirements.
Choosing the Right Submersible Pump
When selecting a submersible backup pump for a shallow well jet pump system, look for a pump with a horsepower (HP) rating that’s close to or slightly higher than your primary jet pump. For example, if your primary pump is 1 HP, a 1.5 HP or 2 HP submersible pump would be a good backup option. The flow rate of the submersible pump should also be suitable for your water demand, typically around 6-10 gallons per minute (GPM) for a residential system.
Compatibility and Installation Considerations
To ensure a smooth transition from the primary jet pump to the submersible backup, make sure the backup pump is compatible with your existing system’s voltage and pressure requirements. Check the pump’s specifications for compatibility with your well casing size and material, as well as any local building codes or regulations. Proper installation of the submersible pump is crucial, so consider hiring a professional with experience in well pump systems to ensure correct installation and configuration.
Additional Tips for Efficient Backup Operation
To maximize the efficiency of your submersible backup pump, consider installing a pressure switch or a float switch that will automatically turn the submersible pump on when the primary jet pump fails or is unable to meet the water demand. This will help prevent over-pumping and reduce the risk of damage to the submersible pump. Additionally, make sure to properly winterize your system to prevent damage from freezing temperatures and ensure the submersible pump is protected from sediment and debris in the well casing.
