Question: does it really remove scale build up
Document: 30 days/works great,hair is softer after bath, I'm hoping it will remove existing scale.time will tell, if so it will be the best on the market
A one year iron clad guaranty would be ideal and remove the risk. After all the customer must bear the installation costs and to ship this product to and from. It would build a lot of good will on their part and the worse thing for them is having to accept back a device that merely holds a filter in place. So the reviews didn't help me much at all but showed I would have to buy this on blind faith.
Much of it appears to me to be designed to move people away from this type of solution in favor of traditional salt based water softener solutions, or expensive non-salt based solutions (one quote I got was $4000 for my home). Remember, many contractors make a nice living just installing these types of water softening systems. The general claims are that the Nuvo solution does not really "soften" the water because it does not remove the calcium and magnesium.
I would recommend that they make that document more readily available on their web site (if they haven't already) as that carried a lot of weight with me. One of my key questions/concerns/doubts was around its ability to reduce/remove limescale that has ruined my shower and faucets in my bathroom. Further adding to my doubts was the explanation that it could take several months to remove the existing scale in my pipes. It seemed like a built in excuse, and the 60 days may not be enough.
We put our NuVo filter on last week and we can ALREADY see a decrease in the scale build up. We have well water and it is extremely hard water. I am amazed at how well it is working and what a difference we've seen in a very short period of time. Thanks NuVo
Well, I've waited months as "Nuvo" has recommended, to see results in my water quality, taste, and a reduction in calcium build up. At first, I thought there was a difference in the taste and quality of water but as months went by and I compared my water to a neighbors water (who had no water filtration in their home) I realized that there was really no difference at all.
The NuvoH2O system may bind calcium and magnesium, but it a misrepresentation to call it a water softener. It might more properly be called a de-scaler, in that (theoretically) it removes and prevents the build-up of scale on plumbing fixtures. But one thing that it does not do is produce soft water, as that term is commonly understood. How do I know this to be the case?
We purchased a house that already had the Nuvo system. Former owner did not tell us that we needed to change the cartridge every 6 months. When scale started to build up we called Nuvo...found out about the cartridge time...and changed the cartridge. It is a little awkward and heavy (Manor model) but a fairly simple proceedure. We needed a bucket to catch the excess water.
We install the nuvoH20 in our home last May. Our hardness was at 350 pmm after about one month the hardness went down to 250 pmm. This product in not a miracle worker but it has reduce some of the white residue on some of the fixtures. The filter was replace after 6 months as you could feel the water getting less soft and more build up of white scale was showing on fixtures. I like the compact size and not having to get salt for the filter.
If you look around the base of the faucet, all of the scale that you see was at least 3x as bad and a lot more discolored. I really wish I would have taken a pic prior but oh well.Before Pic:  Pics are attached to my profile. Click on my name (John O.) above to view them.3. Our glass shower door has tough scale buildup.
