iSpring RCC1UP 6-Stage 100 GPD Under Sink Reverse Osmosis Drinking Water Filtration System with Booster Pump and UV Ultraviolet Filter, Patented Top-Mounted Faucet Design for Easy Installation

I recently purchased this iSpring water filter system] and initially faced a couple of unexpected challenges. First, the faucet that came with the system had a significant manufacturing defect where the spout was not fully drilled through, completely blocking water flow. Shortly after addressing that, a leak developed in the head machine and pre-filter housings.While encountering issues can be frustrating, the resolution process, thanks to iSpring's customer service, was truly outstanding. I want to specifically commend Laurence for his exceptional support. From my very first contact, Laurence was incredibly responsive, understanding, and proactive.He promptly addressed the initial faucet issue and, when the leak occurred, he immediately identified the necessary replacement parts (the entire head machine and pre-filter housings) and arranged for them to be shipped out to me ASAP. His clear communication and willingness to go the extra mile made a potentially stressful situation remarkably smooth.Today, I received the replacement parts and have completed the installation. I am thrilled to report that the system is now functioning perfectly, with no leaks, and delivering clean, clear water.It's rare to experience such dedicated and effective customer service. Laurence's professionalism and efficiency have turned a potentially negative experience into a highly positive one. I highly recommend iSpring not just for their products, but for their commitment to customer satisfaction, exemplified by representatives like Laurence. Thank you, iSpring, and especially thank you, Laurence!

Great tasting RO from our well! Our domestic water pump is set to 22 psi but the booster pump on this unit gets the pressure up so this device really makes water fast. It's pretty quiet while running. It has UV to kill cysts and bacteria. Our water is already basic and hard (Rocky Mountain runoff), so we passed on pH alteration and remineralization. We use this for all our drinking water, tea, coffee, etc., and it's great for houseplants.Easy to install and Julius from customer service made registering for the extended warranty a breeze. I like the clear first filter housing and the extra parts are handy. The included leak-detecting mechanical water supply shutoff is a nice touch as well.

Total value for money. User friendly and easy to install by yourself. Great tasting water. I hope they make one with wifi enabled for filter life checks

To begin I have had now three RO systems in my house for 20 years. I really like them, and do not want to add calcium for taste. It works very well as a replacement for distilled water. I use it in a CPAP machine. The first two were the Watts Premier from Costco. Those were very nice to live with. I bought the iSpring to upgrade from a four stage to a 7 stage to:Replace the leaky faucet I could not repair.Get less expensive filters for replacement.Get greater volume.Produce less waste water, for a house septic system.Microbe protection for well water.This looks like it was made with high quality components. It is said to be effective, with rating, and looks like the components are three times the capacity of the prior quick connect type. All this is good.What is obvious to me is that this was designed to be a four stage, under sink filter system. Then someone had a great idea, and decided to add a pump which weighs a lot and requires electricity. Heck let’s add a UV. The added weight and size was not reengineered. This added electrical demands, that most under sink outlets to do not have. This unit now weighs twice as much with power wires, and tiny control wires, and tubes now going everywhere, out the front and not the back, with snap on holders that may or may not hold the component, and then additional snap on component making a chain of snap on connectors each dependent on first.. The engineers probably said we do not know if that will work for the customer. Marketing said that’s ok, let’s not solve that problem, we will not address the issue, and tell the customer they can solve this anyway they want to.If that were possible I would build my own system, and not buy this at all.All I can say is good luck with the electric wiring, it is up to you. Good luck on finding a wall that can support the weight and leverage needed to change the filters. You should solve this problem before deciding to buy. And there is not enough information provided to allow you to plan this. The control wires are tiny fragile wires with no quick disconnect that are too short to place the control box any where near the electrical outlet. One wire power wire is twice as long as the other, but they are going to the same outlet.All of this makes it too heavy to be supported by the designed bracket, so they recommend you put it on something to support it. No design, no instructions.Then there is included a leak stop valve. Thank you, but no instructions on where to place it, nor how to use it. You must call support, I guess.So back to the choice I made. The watts system is a light weight quick disconnect home owner system. This iSpring appears to more industrial, with old school heavy well made and more durable components. They are marketed to the same customer and made to look the same in pictures. They are not, especially with the seven stages, and marketing needs to admit it. If I were engineering this to still get it under the sink I would divide it into two parts. The permanent elements to be placed on the back wall near the electrical outlet. Then the change out filters properly supported to be changed traditionally placed. That will take weight off the unit, and make it more intuitive to the customer.
