Sentry I Open-Air Inlet Solenoid Kit

Incorporate the inlet solenoid kit with the Sentry I Open Air system for two separate pressurized systems. The system gives you the choice of using treated or untreated water. Install the solenoid on the Inlet of the Sentry Open Air system. The solenoid opens when the float in the system drops filling the tank with water. An untreated line can be plumbed between the well pressure tank and the solenoid for sprinkler systems barns etc. anywhere untreated water is needed. See Open Air systems here
