    I have a deep well (440ft) 1-1/2hp submersible pump that feeds the house. I want to add a chlorinator system and thought that I'd use a 150-250gal poly tank to contain the chlorine injected water AND feed a jet pump for better/consistent water pressure in the house. My thought was to use a float switch to signal the submersible pump, but can't find one online that will drive the 1-1/2hp pump.

    Recap: 1-1/2hp submersible pump in well to chlorine injection pump to storage tank to jet pump to house supply.

    Can anyone confirm /comment /advise on the design idea and provide a supplier reference for the right float switch?

    Just about any float switch can handle any size motor if you use a relay or contactor. The float switch energizes the relay, and the power for the motor is run through the relay, not the float switch.

    This is about what you need. there are cheaper routes, just buy a 2 pole contactor with a coil voltage of whatever you are turning the float switches on with - 24 volts or 115 volts.

    Now the float switch is using less than one amp to operate the contactor.

    The Siemens is a great buy, but the coil is 240Volts
