Rated 5.0 out of 5.0 by Most Reliable, Great American made product I installed the Model 900 15+ years ago and have not experienced any problems. I am on well water and other brands that I have used began to fail after a couple of years. I just recently began to get salty water and followed the troubleshooting guide to clean the injector screen. That fixed the problem, not bad for 15+ years of use. I was very pleased to find out that the product is still being made and the manuals were obtainable online. Most products you buy do not have that kind of longevity. Good to know that this Company has the sense to leave a good thing alone. As the old saying goes " Don't fix it if it is not broke". October 27, 2015
Rated 5.0 out of 5.0 by excellent softner Water softener was easy to install. At my home, incoming water was on the opposite side so I had to Chris cross the pipes. The softener works as advertised. I like the easy access to add salt. When I called for help I was able to get the answer I needed with ease. I consider it to be an excellent value, and gladly recommend it. June 17, 2015
Rated 5.0 out of 5.0 by 2 houses, 2 Water Bosses Have the smaller unit in my rental house, has worked great for almost 10 years. The 30 yr. + softener in our current house was shot, didn't even look at other brands, knew what I wanted. Installation was easy using the sharkbite connectors. Hasn't used hardly any salt since installed (nearly 3 weeks), water quality is excellent. Would highly recommend! October 21, 2015
Rated 5.0 out of 5.0 by Long Life, Excellent Product I have owned a Waterboss for about 14 years, and have had almost no trouble with it. Less than $500 for a softener that lasts 14+ years, that is fantastic. I am going to replace mine now with another Waterboss. Just a little preemptive repair, since it is so old. I see really poor reviews on the current 900 model, but I would recommend this softener to anyone, mostly for the American made quality. It was easy to install, since my house was pumped for a softener. And I love that it has a built in water filter, that flushes the well water automatically every time it regenerates. That is the only filter I have on my house. March 12, 2015
Rated 5.0 out of 5.0 by A great buy A great buy for the money. easy install and great help if you need it from the company. love doing business with Home Depot October 9, 2012
Rated 5.0 out of 5.0 by The best I have used I have been using a Water Boss at my primary home with hard city water for over 25 years and perfect operation. When I purchased a second, weekend home, in the country, it had funky well water with high clear water iron content, so I installed a Water Boss. The second unit has been working perfectly for over 15 years. I see a number of complaints, but my experience has been nothing but completely trouble free. I highly recommend the Water Boss.
