The 'water testing' they do is actually done by RainSoft, a water purification company. I did buy the system only because I do not have well water. I'm 67, raised on artesian well water and, as far as i can tell, by my current excellent health, you might be better off drinking the minerals that are contained in deep well water.
It's a scam. They don't really test. they just call you up and try to schedule a water treatment sales pitch at your home.
They do any water testing. Just take a kit, fill the vile and send it in. Kits are located either at the entrance or exit.
