Review: Great Tankless RO System - Replaced an 8 year old tank system with this. The installation was very easy. Watched the video online at Delta and it helped a lot. Directions are good also. Hooked up to my refrigerator also and the pressure of the water coming out is really good. The noise of the pump is very minimal and not annoying at all. I hooked up a small booster pump to my old system and it was much louder. No booster pump needed with this and the flow is much faster!! Seems to be a quality Delta product. I called Delta to check and ask if the refrigerator needed any additional equipment for good flow and they said it would be good as is. Great customer service.
Review: Noisy and Wastes Water! - This is the worst water filtration system I have ever had. It makes noise like a train is coming down the street whenever you turn on the faucet. Then it recycles every 15 minutes and wastes so much water. Do not buy!

### ⭐ Noisy and Wastes Water!
*by R***Z on 5 July 2026*

This is the worst water filtration system I have ever had. It makes noise like a train is coming down the street whenever you turn on the faucet. Then it recycles every 15 minutes and wastes so much water. Do not buy!

### ⭐⭐⭐⭐⭐ VERY QUIET if you do install correctly, LOVE THIS THING!
*by R***Y on 4 October 2025*

This replaced my old Aquasana RO filtration system that used a tank. This Delta one is far better in many ways and I’m really happy with my purchase. First the total cost of ownership is less, there is no tank so I can use lots of water for cooking and drinking all at once, the system tells me when to replace the filters, it wastes less water and the water comes out really fast and tastes good. Now to the noise. It’s not a problem AT ALL! I was concerned reading the reviews here that it was going to be really noisy when it was running but I can barely hear it in the under sink cabinet and the water landing in my glass is louder than the machine. There is a customer video here of it being really loud which was concerning but after doing my own install I can say as an engineer that if anyone is having a noise problem they either have a defective unit or didn’t install it correctly. If the machine is in spec and you install it correctly you won’t have a noise problem, simple as that. In order to ensure mine would be quiet I had to take some very specific steps - preloading all the water lines with water to ensure when first turning on the unit that no air was sucked in, ensuring no tubes touch the sides of the unit while it’s running by doing a clean and organized install, not using an air gap faucet (they aren’t needed for tankless systems like this unlike the old tank RO systems that do need the safety feature of an air gap), and finally using sorbothane vibration isolating feet on the unit instead of the factory feet which isolates vibrations from reverberating through the sink cabinet and making noise. If you do all of those, you’ll be set! (If you watch the video I attached you can hear the faint dull hum of the machine filtering in the background as the glass fills) (Photo is of sorbothane feet for vibration isolation)
