My irrigation well has probably the highest iron concentration ever seen. About 18 months ago, my latest effort to solve was a "Rust Service Company".
They installed a chemical tank and a small injection pump, wired in parallel to the well pump. Whenever the pressure drops, the pressure switch closes, turning both pumps on, adding a small concentration of chemical.
This chemical is supposed to (I think), entrap the iron molecule, preventing oxygen in the air from combining and forming "rust". Works okay for all the large spray heads, but that larger molecule seems to clog my rotors (over time.
I also have five drip zones with 500 or so drip emitters, all of which are now clogged tight. I am replacing now, but this is a job! Also I have several hundred feet of drip pipe with built-in emitters.
I need a better fix. I am trying to come up with a way to disconnect the injector pump whenever a drip zone is turned on. The iron, although it discolors the emitter and a small area nearby, never discolors sidewalks, walls, etc.
My controller is a Hunter and I have considered some sort of relay cut-out, but acquiring that signal has me stumped. I need a 5-way "OR" gate that accepts and passes 24v AC.
