Gemini Source Control is an automatic municipal water back up device used for rainwater harvesting systems. It will optimize collected rainwater when available and default to a municipal water source if tank water is not available or should there be a pump or power failure. Gemini is suitable for both surface mounted and submersible pumping applications. It can be used with standard pumps or with other pumps that meet with the operational specifications of the Gemini.

• Capable of full municipal pressure delivery: not reliant on the pump pressure being higher than the municipal supply pressure.
• Pump protection built in:
• Run-dry protection: the system reads input from the included tank level sensor and will not run the pump if the tank level is below the sensor.
• Flow protection: the unit will cross check flow after pump initiation and if not present the pump power will be isolated. This protects the pump in the event of poor installation or float switch fault.
• Can be used with any pump that delivers sufficient pressure and flow for the application.
• Variable speed pump drive: this reduces pump cycling when consumer demand is low and conserves energy.
• One piece molded flow path design: meaning less leakage points. The water course is part of the casing.
• The unit is not constructed from off the shelf components.
• Positive selection between municipal and tank water: Design technology prevents oscillation between sources.
• If tank water is available, that is what is delivered.
• Flow performance is 16 gallons per minute at 65 psi static pressure.
• Fully watermarked.
• Competitively priced.
• Suitable for both surface mounted and submersible pumping applications.
• Maximum pressure rating: 123 psi.
