This post starts slow, but gets better.
So I've got well water. Sometimes it gets this rotten egg odor, a sign of hydrogen sulfide in the water. It's not dangerous or anything, but I get tired of running out to the well and dumping chlorine pellets down the tube, waiting an hour for it to oxidize the h2s, then run the water for 4 hours. It's a once every other month task. So getting a permanent solution for the rotten egg smell and getting rid of some of the hardness of water has been kinda high on my "to do list."
There are a bunch of options like a unit that injects a bit of what is more or less bleach or potassium permanganate, then filters it. Or an option that uses pressurized air for oxidation, then produces sulfur precipitate, and then flushes itself daily down the sewer.
So I'm at the home show in Philly a few weekends ago. There's a dude there hawking water treatment. And he actually has what I want, a Fleck brand Air Injection oxidation system. It would work perfectly for my sulfur problem. I inquire and he says he'd need to see my home well situation to recommend the right product. So he offered me a no obligation in-home consultation. I say, sure, why not.
The dude comes to my house and, even though I told him that I chlorinated a few weeks ago, he did a water test. I have very slightly high iron (as would be expected with the H2S problem), but everything else looks good. And I'm like "...um...I just treated it...shouldn't you wait until the odor comes back to test it? If I just oxidized the well, the iron and hydrogen sulfide levels are obviously lower than usual." He, unphased by obvious logic, just told me, "It would be fine." This was just the beginning of the kookery.
So he looks at my setup and says I could "get away" with a 3-stage filtration system with a carbon filter that he manufactures himself out of coconut shells. And he'd sell it to me for the home show discounted price of the display model at the show for $1899 and $350 installation. If I wait, it would be $2299, because he had to build me a new one. I said, "That seems high." And he tells me that its actually cheap because its direct from the manufacturer...him. Then I ask him about the air injection system, which would also work (I've seen them online from between $600-$1200, shipped to my doorstep). He says I could get a small one for about $2200, but a larger one with better flow would be a bit more....and that his system would be a great value.
I could sense in the back of my head that I was being fleeced, but I let him go on. We moved to the issue of water softening. I'm expecting to hear about a normal ass ion-exchange system that I'm sure I'd have the pleasure of paying like $1000 for (plus installation). But he tells me he has this "salt free" solution that will cost me $499 with the filtration system or $599 by itself. That sounded reasonable, so I asked him how it works.
And here comes the crazy ****.
He tells me he has this device that can descale the water. It works by making the calcium take a different form and become more water soluble, but its mostly technical mumbo jumbo...bottom line is that I'll get the benefits of soft water without the "health risks" of "salt added water", nor the annoying maintenance issues of a traditional water softener. And he says, "Trust me, you don't want to lug a 40lb bag of salt down those steps, its dangerous." (Of course, I do t all the time with my cat's 40lb cat liter bags, but I digress.)
So I tell him that I don't understand how it works. And he goes "Not to get technical, but..." I interrupt him and go, "I actually have a pretty large background in chemistry and physical chemistry, please do get technical."
He stares at me for a sec with a deer in headlights look on his face.
So he says, "Ok, then, I'll get technical." He rambles on using a ton of words out of chemistry 101 that barely made sense. Per this dude, what happens is, the water flows though a solenoid and the electric current changes the calcium carbonate into the aragonite crystalline form. Because the relative solubility of aragonite is higher than the other crystalline forms of calcium carbonate, then it will descale your pipes as the magic of osmosis moves more of this buildup into solution.
Me: "Ok, so after it goes through this current, it crystallizes into aragonite? So I'll have little calcium carbonate crystals in my drinking water?"
Him: "No, it stays in solution."
Me: "How does something in solution have a crystaline form? That makes no sense. At all."
Him: "No, no...its not IN SOLUTION. Its in a sub micron space. Little crystals are formed too small to detect."
Me: "So its a microscopic SUSPENSION."
Him. "Yes."
Me: "Right. I really don't understand how this makes sense. If this aragonite is more soluble, then why does it not go back into solut..."
At this point, my wife sensing the dude is crazy, too, wants me to stop arguing and to get this nut out of our house...and tells me "Hon, I think you're just overthinking it." And smiles at him. She's smart. I let it go and he completes his spiel. After my hard inquiries, he started taking the bizarre steps of complimenting my house. He told me my front room was "breathtaking" at first glance and that my hardwood floors (bamboo, but, whatever) were incredible.
It kinda got weird.
Eventually he left.
Amused, I looked this nonsense up.
This .pdf succinctly vindicated my skepticism. Thank you random professor and trade organization for setting it straight.
So I looked this magical electric crystal formation guy up. Out of the same location as his water treatment business (
here...if you care), he has a used car lot, sells insurance, and runs a medical billing business.
Dude is a professional huckster.
I'm about to just buy a Fleck unit online, an old fashioned ion-exchange resin water filter from Sears or something, and hire a random plumber to install it for me. Prolly cost me about $1500 total or so.
