Still shows as hard water
I live in a hard water area and I will say that this device does keep the scale from sticking to things. It however doesn't lower the number of solids in my water. My TDS meter still shows the same number.

Worked perfectly
I don't live in an area that has ridiculously hard water. I believe we have a hardness of 125 ppm. This is why it worked so perfectly. Hard water is merely a nuisance and it's not at a level where I need a water softener plus I don't want to add sodium to my water. I simply want the annoying staining to stop. After 2 weeks of being installed, it did its magic. The hard scale deposits went away and the ones that were left over were easily wiped away. So glad I get to keep the healthy calcium in my water and not have the problems. Well worth the money. I had previously tried a similar device that used magnets, It did nothing to help with the problems we had.
6 months in use
I decided to wait to put this review up so I could see if it actually worked before I threw my 2 cents in. I have a 2 story home with a water filter. Unfortunately, the filter didn't do anything about the hard water issues I have After 6 months I can say I'm very happy with the results. I'm not sure why, but I do need to change my water filters a little more frequently since installing it. Apparently, these devices must increase the filter's ability to grab the particles out of the water.. This was a pleasant surprise since I was only expecting it to help with the scale build-up all over my home's plumbing system, which I'm happy to report that it did.

First time I've tried this
Ive had this installed about a week and so far it appears to be doing its thing. I have noticed that scale is present in some areas but it does wipe away easily.
Update on my HydroFLOW
I hope this finds all of you well! Just thought I'd give an update on my Hydroflow. Last December (2020) was the last time I needed to clean the coil on my boiler. I did use a different technician the last 2 times who uses an all natural product and perhaps that has made some difference. However, I think the real impact has come from the Hydroflow which over the course of several years cleaned out the pipes of accumulated scale. They must have been terrible! I have much less scale, if any which comes out of the faucets. I hope this continues! Nancy
Did not soften my water
I was expecting to see my water hardness go down. It didn't. I did see scale disappear from my fixtures but my TDS meter still shows the same hardness. Apparently, this does remove the scale but doesn't soften my water.

The effects of using HydroFLOW is my apartment
My mom has terrible water, her water is so bad I won’t drink it. She lives in an apartment, but so do I. The difference is that I have HydroFLOW installed on my piping system. After about a year of attempting to get her to visit my apartment and see the difference, she finally came for a visit this last week and could not believe how my water made her skin feel, how much better her hair feels and the difference in the taste of the water. There is another thing I have noticed this past year. Since I started using a HydroFLOW S38 unit, I have gone an entire year without any of the colds of flus I have been used to, showing up like clockwork every winter season. The only thing I have changed in my life is that I have this unit in my apartment. I also wanted to add that at work, I bring water from home, and often find myself sharing because there is such a difference between the water in my home, and the untreated water that my work place provides.

A friend recommended it
I wish I had known about your product years ago. I do not like softened water. Its terrible to drink and terrrible to take a shower in.
Exactly does what it says
I was pleased to see this did exactly what I expected
Brad Angel
Earth friendly and better than a water softener. This was really easy to install and it really seems to be working. I have no buildup on my faucets and water seems to be running clear.
