Recommended: 3/4 HP Submersible at $2,700.00 installedYour well requires a pump that can handle 189 ft of total dynamic head at 10 GPM. The 3/4 HP Submersible is the most cost-effective pump that meets these requirements. With 12 fixtures, plan for peak demand of 14 GPM during simultaneous use.

This is an estimate for planning purposes. Actual pump sizing depends on well recovery rate, water quality, pipe diameter, and local conditions. Always consult a licensed well driller or plumber for final system design.
