App Concept

AutoPrime TankFill

Smart pump controller that automatically primes the pump to prevent air locks and shuts off the pump when the tank is full. Uses a float sensor and a purge valve to eliminate air, plus a pressure sensor to detect fill level and stop the pump before pipes knock.

Key Features

Automatic pump priming cycle to expel air locks
Float or ultrasonic level sensor for tank full detection
Automatic pump shutoff when tank reaches set level
Pressure sensor to prevent pipe hammer and overfilling
Manual override and status alerts via LED or app

Target Users: Homeowners in areas with intermittent water supply who pump water to roof tanks using a force pump

Revenue Model: $199 one-time device + $9/year optional monitoring subscription
