Finally done, thanks to the help of nice customers of the company. Inga-Ro system. Thanks for that. Unfortunately we were given by the distributor only reluctantly help installing the device. We had at the 3rd request and with the phone call, the feeling that you think we're stupid. My husband is really technically gifted, but so was a work for him again. But GSD is the device properly. The measured values are top, even far better than the expensive medicinal waters, which we've been drinking. The osmosis water tastes great.
