In June of this Year I purchased a Wk1 water conditioner for our home. We live in a typically hard water area and our well is completed in granite rock. Our home has oil fired hot water heating, and I was noticing that the hot water tank was firing for longer periods of time, with snapping sounds near the end of the cycle. I acidized the tank to dissolve any deposits buildup, but this didn't seem to help.
After installing the WK1 ,which took abouty 10 minutes, I went upstairs to taste the water. Immediately I noticed less taste in the water. After a week I drained my hot water tank. There was so much material ( about 3mm in the bottom of my laundry tub) , that I thought I had developed a sand problem in my well. After draining off about 20 litres, the sediment stopped coming. Acid reacted with thje sediment proving that it was calcium carbonate ( the "lime" that buildup we see in kettles). Weekly, for three months I drained the hot water tank and the amounts diminished each time. Now I drain it once a month. No more "snapping" sounds at the end of the firing cyce (deposits heating up and breaking). The WK1 will save on our fuel olil bill this winter.
Another benefit I noticed is that any hard water stains are now much easier to remove. There is minimal film on the glass shower and it cleans up with normal household cleaner. Before installing the WK1, Tilex or other more powerful products had to be used for cleaning.
I'm very happy with the unit and there is no maintenance whatsoever.
Thanks again. All the best in the New Year
