My Clean Water system was installed on April 24. A picture of the installation is attached.
Water from the well enters the basement just to the left of your blue filter, goes through a 1 micron filter (we still have considerable sediment from the well even after 7 years), then to your filter, then through the clean water system, then to the house. (The filter and line to the left goes to a shop/barn 300 feet away.)
I noticed a change in the house water almost immediately.
Most noticeable was on a glass door in the master bedroom shower – it always had a white film on it, which was difficult to remove (probably lime). That disappeared almost immediately, along with the white residue around the fixtures.
We are very pleased with your product.
