I have a chlorine feeder (120v Stenner 45) that is supposed to run at the same time my well pump (240v) is running.
Currently they are set up on separate pressure switches, with the chlorine feeder set to switch on (40.x psi) slightly before the well pump (40 psi) is triggered and off slightly before (59.x psi) the well pump (60 psi) shuts off. Obviously this isn't ideal because A) it is hard to keep configured and working properly, and B) there is a chance that the chlorine feeder could be triggered, yet the well pump not get triggered (there is at least quart difference between the 2 trigger pressures), leaving it to run longer than needed.
As I see it, I have a few options:
- Buy a 240v chlorine pump and run them off the same pressure switch ($$$).
- Find a different type of switch for the chlorine feeder - e.g. flow switch.
Find another way to run the chlorine feeder off the same pressure switch as the well pump. If it's possible, this seems like the easiest approach. The 240 well pump line has 3 wires, I presume black and white are both hot and the ground. Is it possible to wire this switch to a 120 device (and leave it on the 240 well pump)?
