Nice system, no issues. Built a small utility closet outside my kitchen and installed it there so as not to crowd the bottom of my kitchen sink. Makes it easy to supervise and change out filters. If there is a leak it won't be in my kitchen.

Sean was very extraordinarily helpful with this problem, but that is typical of iSpring. Excellent water quality and excellent service!!

We've been using the RCC7P system since 2018, and due to some misunderstandings, we only just now did our first system maintenance and filter replacement in early 2023. Although we're well past the filter replacement schedule, this system has been performing great the whole time through; we use it for watering plants and other sensitive needs that require pure water (crucial when you live on a well with high iron levels in the local water table). The only issue we had with replacing the filters was the fifth-stage post-carbon filter, where the older one we had had a sealed-on screw-in fitting. Michele & co. helped me sort out what I needed, especially after a mishap with ordering the wrong size fitting, and after getting that in quickly, the new filters work great and the whole system works as fine as it ever has. Now that we have new sets of filters ready to go and a better understanding of how to maintain it, I look forward to many more years of great water!

RCC100p has only been in for a week but is working great. I had zero problem installing and what has to be close to a miracle...not one leak. I have had RO systems since 1993. the water in las vegas was very hard. I had a custom system in LV with a pressure pump. I forgot how good they are. I now have a larger than normal tank. It hold apprx 3.5 gals. It filled it in less than an hour. My old system was from that company that sounds like a light bulb rating. It was in use for 15 years but not problem free. I had about 5 repairs over the years. This system replaced that one. My system has a under the counter ice maker so it uses a lot of water. My tap water in upstate South Carolina is very good but things can still get into the pipes. Tap water is 40 PPM. RO water is now 2 PPM , the lowest it has ever been. MY 2 cents......If you can afford it...get the system with the pressure pump you should have all the water you need. So far very happy with my purchase.
