[...] Well, the fact that we (US Water) sell the GreenWave and not Pelican should say enough about it. I also believe that DVGW-512 is of no value. The Pelican system is “Third Party-Tested.” What does that mean? It could mean that they gave someone some money to test it and they said it was great. As it stands right now, there is no Certification, Testing or Validation of Salt-less or Salt-free water conditioning systems by any credible testing facility. The DVGW-512 standard is dubious, at best. (See previous post) [...]

The Water Doctor Replied:

“Properly applied” means that it is on water that does not have iron, sulfur or manganese and that the consumer understands what it will or won’t do.

Mark,

You indicated that the Green Wave can do an excellent job of preventing scale when applied properly. Can you explain what do you mean by applied properly and how would we know it is applied properly?

Thanks,

Wayne

Dick,

Sorry for the late response, but I have been gone for a few days.

The Green Wave is the product of years of testing and is also evolving. The biggest thing is that it does what we say. It doesn’t soften water or make “naturally soft water” like some companies claim. It doesn’t make soap lather better or make clothes whiter and brighter as others snake-oil salespeople claim. Those are out-and-out lies which are totally false!

The Green Wave can do an excellent job of preventing scale when applied properly.

One thing to think about however (and other companies LIE about this): With a salt-based water softener, you use about 50% leass soap, chemicals, detergents and other products. What effect does that have on the environmnet? I don’t have the answer, but it is something to ponder.

Do you still stand behind the Green Wave line of scale control devices? I am an environmental chemist with >40 years of experience, primarily in solid waste. I do, however, have some experience in water, primarily wastewater. We live in an area that has significant scale. Water softening is not an option – the rivers that I fish are severely depleted by urban withdrawals; the fish are already highly stressed, and adding sodium to the streams will stress them further. Because of all or the foregoing, I am looking for something that will reduce scale buildup without adding ‘softening’ cations.
