## Questions & Answers

**Q: What are the dimensions of the holding tank, and what is the ideal pressure that it should be maintained at?**
A: Tank pressure at 6 psi when empty seems about right. Higher than that gives a greater output pressure but less storage.

**Q: If the waste ratio with booster pump is 2:1, can i achieve that ratio with the pump with city water of 55psi? trying to get 2:1 with 55psi input. thx.**
A: Honestly who cares.  Rought your ro waste water line to rain barrel, garden or other use if you are concerned.  Water still cheaper and better than bottled and honestly the unit with pump is cheat.  I rough my wastewater to the mop sink where I can keep an eye on it.  Not much waste with the system I have.

**Q: Does this remove pfos, pfoa, and other pfas chemicals?**
A: Hello,

Thank you for your question.

Yes, the NU Aqua Platinum Series 6 Stage UV Ultraviolet 100GPD RO System with Booster Pump will help reduce the PFOs, PFOA, and other PFA chemicals. If you have any further questions please feel free to let us know.

Best Regards,

**Q: Will this RO system work with a sink faucet, and ice maker?**
A: Yes - that is how I installed.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent Value! Great water!
*by J***. on January 14, 2021*

Being someone who has been around RO systems for quite sometime now, this setup is nothing out of the ordinary. The quality of the components, design and filters are all typical to what you would expect to find in a system of this caliber and price point. Installation is straight forward and the included pump is on par in noise levels and performance to those of the pricier big box brands. Water is clean, clear, and crisp. I'm able to achieve TDS levels in the single digits (3-5), with the tap coming in at around 50-55. I see some reviewers posting negative reviews for the lack of available filters from the manufacturer, and I just want to state; 1 - the lack of availability of filters for almost all types of water filtration systems have been effected due to the on going pandemic. Restrictions and newly set protocols have caused world wide logistic delays, not to mention the direct effects of limited staffing, and shortened hours of business. This will naturally pass, but yes, for the time being, there are shortages out there. 2 - now with that said, not everyone is experiencing such shortages or delays, and you do not have to use this manufacturers specific RO filters. You can use a combination of filters from other RO systems and achieve the same, if not better results. The filters this system needs are available in abundance right here on Amazon, from many other manufactures and suppliers. All in all, I'm very happy with this setup. No surprises, easy to maintain, and consistent with what it delivers. That's exactly what you want an RO system to do. Nothing more, nothing less.

### ⭐⭐⭐⭐⭐ Great kit!
*by D***J on December 19, 2024*

I'm glad I purchased this system. Price was right.Good quality.We have filtered a lot of water with this for drinking, coffee maker, and beer brewing.Checked it with meter after a year of use still working perfectly. No residue or film in clear resevoir of Keurig . Never have to run cleaner through coffee maker. This unit includes a pump assist. I think most every install needs that feature.Your water pressure is probably not high enough to push through the osmosis membrane and filters at an adequate rate. Side note . I use a whole house water softener in line first. Can't say how often filters would need replaced if well water is very hard.

### ⭐ Order from the manufacturer directly.
*by S***A on February 10, 2023*

When it arrived, the main inlet was broken so i had to order a replacement part. When that finally arrived, it had 2 different leaks because it was missing gaskets. When i bought the gaskets and finally put it all together and start it up, the pump shorts out and starts smelling like smoke. I gave up and hope they give me a refund.I ordered the same item again through the manufacturer website and it was so much better. No issues, set it up immediately, good water. I did notice that the one they sell here is an older model.
