bought the manor nuvo h2o system last year because of very hard water in our area. I falled for the false advertisement, which I'm sure am not the only one. The problem I still have is the soap scum in the shower glass door and tile walls. Also, corrosion buildup on plumbing fittings joints. have to replace shut off valves. Tap water still has a the same unpleasant taste as before. I have to buy the drinking water. I am totally dissatisfied with this system. I am still looking to find a system that works as advertised. I have tried the Zeta Rod. It did a little better than the nuvo h2o. Might just have to go back to it since I have it stashed on the shelf somewhere.
