Pelican vs. GreenWave and DVGW-512

July 28th, 2010 · No Comments

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.

DVGW-512 – Urban Legend?

February 11th, 2010 · 5 Comments

More and more people are wondering if it really exists?   DVGW-512 is allegedly the standard for testing salt-free water treatment systems.  In fact, one company (WATTS) is claiming (in a convoluted, round-about way) that their product is approved by DVGW-512.  Check out this LINK if you want proof.  While they don’t actually “LIE” they lead [...]

I would encourage anyone who is looking to go “salt-free” to think about whether the company they are considering is really a “water treatment company” or just a company that is interested in selling a salt-free product and little else.

Do Salt-Free Water Softeners Really Work?

December 25th, 2007 · 350 Comments

I talk to many people each day, inside and outside the water industry,  and the claims by many companies who are trying to sell salt-free, saltless or no-salt (call them what you will) are really confusing.  Many are also not rooted in fact.  I try to keep an open mind and I am receptive to [...]
