This was super easy to install. The water truly tastes great now as well as coffee. It’s noiseless with plenty of fresh clean water to accommodate a family of five. Express Water has made this very easy to install. 3 month update: working flawlessly. Still the best tasting water in town. All we drink now is water and coffee or tea made with this water

Reviews are great. My nephew has had it for years and highly recommended it. I looked at several different RO systems and got this 100 Gallons Per Day reverse osmosis system with UV filter. Whole house was too expensive and too hard on my septic tank. This installed fairly easily. The flushing procedure was lengthy, but now we have worry free drinking water for cooking, coffee, ice, and pets. Our well water is high in iron with a bad taste and there is always a concern for bacteria with well water. This Express water UV reverse osmosis system gives us great tasting water with the security of a UV filter to kill bacteria. The UV filter leaked badly on startup. I had to remove the quartz tube and reposition the Oring which stopped the leaked. The tank leaked from the top fitting until I tightened it a little more until the leak stopped. The 3 big filters on the bottom all leaked. It said the O rings were pretreated with food grade silicone lube, so I didn't add any. If I had to do it again I would put a film of food grade lube to ensure a good seal. I had to tighten all 3 large filters a lot to stop the leaking. The spigot handle was loose and dripped on the counter, but after a few days it tightened up and stopped leaking. I guess the internals needed to swell up with water and make it tight. Overall we are very happy and excited about this system. It will pay for itself in 5 months for the cost of water we were buying to drink.

This is the 11-stage RO filter setup with UV sterilization and alkaline remineralization stages. Everything is pre-packaged in a way to ease installation but kind of a pain if you're planning to add a permeate pump or branch out the lines before/after the remineralization stage (to get regular RO water for things like a coffee maker or other cooking needs while getting mineralized water for drinking). Overall, while it's assembled rather well, it's still quite bulky. I was surprised that the 4-gal tank isn't the most imposing component. The 3-stage primary filters at the bottom of the kit dominate the space. The RO, UV, ALK, and PAC units mounted horizontally on top are quite a bit smaller. That said, the entire kit will fit in the cabinet under a common double sink under the one WITHOUT a garbage disposal. If you have a garbage disposal under one sink, space will be tight (at best) on that side so plan to install on the opposite side. I'm pretty bad at plumbing but installation was actually rather easy thanks to most of the work already being done with the 1/4" tubing and quick-connect fittings. It took me MAYBE 90 minutes start-to-finish (plus the fill/flush process afterwards). The hardest part was connecting the tubing to the included faucet which, in hindsight I could have made easier by fishing the tube up through the retention nut, the countertop, the top washer then onto the faucet stem before securing the faucet to the countertop. Instead of the included drain "saddle" I opted for a "Y" tube that fits inline with my dishwasher drain into my garbage disposal - no cutting required. I opted to add a permeate pump, as well. That requires some re-routing of some of the pre-installed tubes but isn't all that complicated once you understand how it works and where each tube comes from and goes to. Overall, that reduces the wastewater by a significant amount (sorry - I don't have before/after stats). It also reduces the total fill time from 2-3 hours to about 35 minutes and makes flushing/priming new filters a LOT quicker. I did have one faulty connection in the system that needed to be fixed and it was one of the factory-installed ones. The "T" that feeds the PAC (the final filter) and the tank wasn't seated correctly and leaked straight away. I simply removed the tube, re-cut the end, and reinstalled it - job done! No leaks of any kind after that. I also opted to NOT physically mount the unit inside the cabinet. I know filter changes are going to be a pain so I simply left it sitting on the bottom of the cabinet with enough slack in the tubes to remove it to the floor in front of the cabinet. From there, I can disconnect all my tubes that go back under the sink and re-work the filters up on the counter or in the sink, as needed. The municipal water supply where I live is actually already pretty good. I just wanted better tasting water. We've used a drip-type filter for a few years and it does an okay job but I'm still finding a slightly "off" taste occasionally. This RO system TOTALLY removes any hint of weird odors/tastes and is better than many bottled waters I've had. Fiji is as close as it gets. Get yourself a glass pitcher, fill it regularly, and keep it chilled in the fridge. OR get a "T" tap off the feed to the RO faucet and feed it into your in-fridge water supply for the best ice and water you'll ever taste.

I really would love to give this 5 stars however I’m a little disappointed with the setup startup process. It takes 5 full tanks of water to fully clean out the system and the water is suitable for drinking. We are on a well so this was a waste of water AND electricity to run the well pump as it took a full day to complete the process. I think they (express water) should improve on this! The good side is that it was easy to install. I did it myself I a couple hours. Hardest part was getting the screws for the mounts in the right place. Another thing they could improve one is including a diagram of the screw holes you can stick to the side of the cabinet then make your holes. Now I have about 6 unwanted holes! And I’m not super strong and it’s an awkward position under the sink... The install of the tubes is tricky as you absolutely need to make sure they go in all the way into the fittings or you will have leaks at startup. You can feel when the tube is in place. You’ll know it when you feel it. These are 1/4” tubes so if you’re replacing a system with 3/8” existing you’ll need extra fittings, my husband picked me up a few at Home Depot. I kept my incoming line as it already had a shut off valve and I kept my out going as it already had a T for the ice maker and I liked my current faucet rather then the cheap looking faucet they sent with they system. This could also be improved upon. All together great system, water tastes great. Could use some improvements but that doesn’t effect the overall usage just would make things nicer.
