I bought this over a year ago and it works like a charm and I've had no issues since. Try it.

HS48 after 1 year of use
Our HS48 is still performing well after 1 year of use. We installed it into our newly constructed home and have NO difficulties. We have NO scaling on any water-use appliances or the showers, but from our underground sprinkler system (which does not have the benefit of the HS48) we have scaling on the exterior of our house. Yes, our municipal water supply is extremely hard, but the HS48 is doing its job and we have NO issues with calcium buildup in our home. I would definitely recommend the Hydroflow unit ... it's easy to install, compact, and exceeding efficient!

I love this product. It takes up virtually no space and serves my whole house. There is no maintenance and it just works.

I'm very impressed! I really noticed it on my glass shower doors, they are crystal clear. Dishes from my dishwasher have no streaks now!

Easy to install and worth every penny if your water is hard which gives a scale buildup on your aerators and on your shower walls. It doesn't take very long to make life simpler and put a smile on your face. Once installed the cost is almost nothing for the small amount of electricity it uses but the benefit of having it is huge. You will get to love it as much as we do, especially with the benefit of not having to use all the salt needed with traditional softeners.

We were a bit skeptical, but we ordered it, installed it, and are loving it! Within 24 hours we were seeing and feeling a difference. Our skin isn't as dry and the sinks are much better looking. There are still water spots, but they wipe off without chemicals!!! Amazing. We have been using CLR for years to clean the sinks, and it is no longer necessary. Well worth it.
