Express Water Alkaline Reverse Osmosis Water Filtration System – 10 Stage RO Mineralizing Purifier – Mineral, pH +, Antioxidant – Under Sink Water Filter with Remineralization – 50 GDP

The RO system comes well packaged and each part is color coded for easy The instructions are very easy to follow with the color coding and step by step navigation. If you can assemble Ikea furniture you can easily install this unit by yourself. I was able to fit it under my sink even with a large garbage disposal there and still had room for cleaning products. I recommend giving the entire instruction pamphlet or read over before starting to assemble stuff. Most of the filter is pre-assembled. Really all one has to do is install the three main filters and attach a couple lines. Then follow the initial flush procedures. The hardest part is going to be drilling a hole in your stainless steel sink for the faucet. I followed the drilling directions on the faucet box. One your 1/8 bit stops penetrating, then switch to the quarter inch and that'll help mill it down. Once the quarter inch penetrated the stainless steel I switched to a cone bit. Drill at very slow speeds and squirt a little WD-40 around the bit drilling area to keep it cool. It took a little while however I was able to install the faucet on top of my stainless steel sink. Followed the flushing procedure and had no leaks and didn't have to adjust anything. The water pressure coming out of the RO faucet spicket was surprisingly good. I did some testing with a digital water hardness tester I bought from Amazon. My tap water hovers around 237 parts per million. This RO system, once it was flushed, was putting out drinking water that tested around 25 parts per million. That is excellent in my opinion because I'm also using the alkaline restore cartridge. Water tastes great and is refreshing and I'm very happy with this purchase. I use the filtered water in my coffee maker, humidifier and I fill up a half gallon jug to keep in the fridge for daily drinking water. I'll probably swap out the Chrome faucet for a brushed nickel to match the rest of my sink accessories.

I love having it ! I needed to have it installed for me. I now have good water for tea coffee or just to drink and without having to lug cases of bottled water in from the car. I have another being installed for my refrigerator ( not close to the sink)

It was easy to install the system. Use for 3 months and had no issue, so far so good, water tasting good. This system is great RO for great price. Very happy with this RO system.

This system was easy to install and has produced really good tasting water. I used to flavor my water but don't need to do that with the water from this system. I'm very happy that I found a great reverse osmosis system for a great price!

Product was pack with care, installation instructions were simple and clear. Its very easy to install and the customer service line is very helpful if you have any help during the installation. The water taste is great and we recommend this product and we will buy any product from this company.

I'm an old man, I'm not as quick as I once was in mind or body. But I can say that installing this system was easy even for me. Don't let the prospect of a difficult installation intimidate you from reaping the benefits of clean water, as I once did.

This unit makes real natural alkaline water so pure tasting. Hooked it up to my ice maker also and my ice is crystal clear! I live in southern California so our water from the Tap is not something you can drink or make good ice with. Very satisfied with this purchase.

This company is so professional. During installation, I got stuck and wasn't sure what to do. I was totally stumped and decided to give them a call. A wonderfully helpful lady named Angie took my call and patiently heard my out. She realized that I was missing a small part that was necessary to complete the installation. I couldn't confirm if I had lost the piece during the unboxing, or if they had forgotten to include it in the box. It was no matter to Angie, and she immediately set-up a replacement order to send me the missing part for free. She told me to call again if I needed anything. In a couple days when the part finally arrived, I breezed through the installation and had it running and spewing out clean water in no time! I wanted to call Angie just to show my appreciation, but didn't want to crowd their phone lines. They're probably really busy. So, I'll just say it here. Thank you, Angie!

Poorly designed screw on filter cartridges prone to leakage unless really torqued down (their interpretation of "snug"). The filter wrench wouldn't allow for a good grip on cartridge cannister. I would use cartridges with quick connect fittings. Top of tank screw-on fitting leaked bad even when torqued down snuggly. Easy fix with a hose end washer and some food grade silicone sealant. Most important thing, "READ THE INSTRUCTIONS!"

The system was relatively easy to install. That's where the positive review ends. I've called customer service and received no call backs. I can't even fill up two gallons of water during a 24 hour period. I've expanded the bladder. I've tried everything in troubleshooting. One gallon of water a day is 30 gallons a month I'd be better off buying water and getting it delivered. Complete waste of money.
