How does the pump maintain pressure automatically?

The pump uses a pressure-sensitive switch that senses open faucets and starts the motor instantly, then stops when flow ends. That on-demand behavior eliminates manual switches and helps conserve electricity and water while ensuring pressure is ready when you need it.

• Automatic pressure switch activation for hands-free operation.
• Stops immediately when taps are closed to prevent cycling.
• Stable 50 PSI delivery to support showers and appliances.
