It was much easier to install then I thought it would be. The only leak was a pre-installed section of tube that I had to reinsert. The book instructions are fine but the linked video in the book was much easier to follow. The RO system works great and I'm very happy with this purchase.

I'm pretty disappointed. There was a shipping mishap where I never received the 7 stage reverse RO system I ordered. Nu Aqua sent it through Fed Ex, Fed Ex Lost the package, I worked with Fed Ex to find the lost package, Fed ex said they delivered but they DID NOT deliver to me. I'm sure Nu Aqua paid for shipping insurance., and now they want me to jump through hoops and get a police report for a missing package to get a replacement. This should be between Nu Aqua and Fed Ex, I did my part and paid for my unit, Nu Aqua needs to step up and fix this.

works well

The reason I did not give you five stars is because when I ordered a seven stage replacement set, you sent me six items. I know you people are better than that just based on the quality of your product.

The filter arrived quickly. I purchased to replace once I need to. Haven’t tried the new ones but I expect them to work as well as the ones I previously purchased.
