iSpring RCC7, NSF Certified, High Capacity Under Sink 5-Stage Reverse Osmosis Water Filter, RO Drinking System, 75 GPD, Brushed Nickel Faucet, Patented Top-Mounted Faucet Design for Easy Installation

Good instructions very easy to install -I bought the RCC7 and I had no leaks - tank fills and everything works - The only thing is the leak detector does not work it stays shut but I dont really need it. Water is cool clean clear and taste great yippie no more bottled water very happy - had a question and their service support contacted me and Nick was the best - very polite, professional, courteous, respectful, spoke clearly and had great instructions. Definitely rock solid product and service thanks

I just installed it at my lake house. Works great with my well water, it taste great. This was a great product a great price. It was easy to install with the great instruction provided. A good DIY project.

Paid a lot to have an RO system installed and serviced at our last home that was on well water. Was surprised how inexpensive RO systems have become and we decided to try to install ourselves. The biggest problem in our new home was reconfiguring the connections on the basic filter system we inherited. A trip to the hardware store for adapters and caps solved the initial hurdle. After that the RO system was quickly and painlessly installed; filters also look easy to replace semiannually. PPM testing confirmed the high quality of the water. We’re happy campers…

Works well. No leaks. No hard to remove and failure-inducing dust plugs on the unit as compared to a competitor's product. Instructions and illustrations are very clear; therefore installation was easy. Better quality fitments and a sturdier frame and filter housings than the competitors. Better filter cup and socket design (for the three pre-filters) than the competitors, so less chance of leaks. Appreciate the inclusion spare parts, even though I didn't need them now. All filters and the reverse osmosis membrane unit look identical to the competition's but without microscopic examination, I wouldn't know if they come from the same manufacturer and have different labeling or if they are also of better quality. I mention competitors only because I just returned one such unit after two weeks of struggle and bought this one instead.

It looks more complicated to set up than it really is. I would just suggest having plumbers tape on hand just to guarantee the seals of all threaded parts. Also, make sure you account for all hose ends before you turn on the water! I've had it installed for a few days now, flushed out 3 tanks, and the water tastes very clean and crisp. Makes great soda water. No issues with leaks yet (even without plumber's tape or the anti-leak valve), but the paranoia is real... Great system and quality parts. I installed it in my old townhouse rental just fine, but for the waste water hose I tapped into the flex hose for the garbage disposal I installed.

First, this came quickly, extremely well packaged (couldn't break something if you wanted to) and mostly quality components. The only "iffy" part is the plastic supply valve as I've not had good luck attaching plastic to a metal supply. Instead of contacting Ispring like I should have, assumed they didn't make a metal version and ordered one from one of their competitors. After I told Ispring I had done this, they let me know they could have provided the same valve and would still do so under warranty. It's entirely not their fault and the plastic valve probably would have worked just fine but I obsess about plumbing leaks. Our water in Tucson, AZ is HARD - 400+ PPM. If you try and use it in something like a coffee maker, it will destroy it in a matter of months. I had been carting water from the local vending machine but we just redid our kitchen so it was time for an RO system. It has brought the TDS down to a consistent 13-14 PPM and the flavor of the water is fine (much better than chlorine and a ton of minerals ever tasted). The faucet provided is nice, matches our new stainless steel commercial kitchen faucet. It do wish there was a different connection to this metal faucet rather than the John Guest quick connect fitting but it's not leaking and the plumber who helped install this said it's the same fitting on his at home and every one he ever installs so probably worried over nothing. Okay, so how to improve. All RO systems need the "main" filters replaced every 6-12 months and when changing them, you must flush the system for 4-5 minutes before allowing any water to flow through the RO membrane filter. As the system comes, it requires disconnecting the supply to the membrane filter and flushing through it into a bucket until the water runs clear. There are two problems with this method of flushing. First, it's always been recommended to me that when you remove a line from these quick connect fittings, that you trim it back past where the little metal teeth gripped it. Supposedly not doing so it one of the biggest causes of minor leaks. Well, you would only change filters so many times before the line to the membrane filter was too short to reconnect and you're adding more tubing. The second problem is that frankly, it's a pain in the neck to unhook that line and then sit there with a bucket trying to determine if the water has cleared yet. Both of these problems would be easily solved by a Y valve where the supply line fed into the single side of the Y and then you had two valves on the V portion. Your could then turn off the supply to the membrane, turn on the supply to a flush line that is now long enough to reach the kitchen sink. No disconnecting and reconnecting lines in an awkward position under the sink. Unfortunately, no one makes such a Y fitting so I had to get much more complicated and fabricate my own system. I used a 1 into 2 splitter, attached a cutoff valve to each side coming off the splitter, added more tubing to one side and can now control where the water goes. The problem with this is that if creates too many more potential leak points . If you look at the picture, you'll see the configuration I had to come up with. The red line coming from the back of the filters used to feed the membrane filter and was the one you disconnect during install and then during any filter changes. Now it feeds the splitter, the splitter feeds the valves and the valves feed either the flush hose or the membrane hose. I shared this with Ispring and they said they would have their product development people look at it. Problem is, no one makes that valve and so creating it from scratch may be bit expensive and you'd need some patent permissions to do so (I'm assuming on that part). One last idea. Our kitchen configuration, unfortunately, has some dead space where cabinets make an angle. It's unusable space, not accessible in any way. So, I cut out a square in the side of the cabinet and installed the tank in that dead space. I can easily get to it but don't have it taking up space directly under the sink (see photo). So, solid product from what appears to be a very solid company. If you think you need something they didn't provide, don't hesitate to ask - they are very accommodating!

This was pretty easy to set up once we received the system. The only thing I would say is there were too many instructions- it was a little hard to know which ones to follow- we had to also watch a couple You Tube videos. But it is working great- and we had quick response from the staff, especially Robert, when reaching out to get our product registered for the warranty.

Excellent filter, I've been using it for about six months now. If you're handy you can install it yourself and it was kind of fun looking back on it. I had a small issue crop up but Francis in Customer Service was able to help me out, great communications. I use it several times everyday, it's been a solid performer, and if I ever move I'd buy another one right away.
