Installed this water softener with relative ease. The instructions were straight forward and didn't require an apprenticeship in plumbing to accomplish. The water is nice and soft, but what I love the most is how long the salt lasts. Filled it up to level 8 in October and it's only dropped to level 6 in the 4 months since. The control panel estimates another 400;days until empty. I thought it was a malfunction, but the water is still super soft. I would definitely recommend this softener.
