Express Water Universal Chiller Cooling System for Water Filters – Compatible with Reverse Osmosis Filtration Systems – Includes ¼” Quick Connect Set-Up

I purchased with an under sink RO filter and a flood monitor. The filtered water goes through the chiller and out the countertop dispenser. The flood monitor detects any leaks and controls the water shut-off valve just in case the RO unit, plumbing, or chiller failed. I use the cold water for drinking and also fill my countertop ice maker for crystal clear ice. I do wish it chilled the water even colder, but it's definitely refreshing on a warm summer day right out of the tap. Runs quiet and I've had it for almost a year now so I would say it's also dependable.

I've had TWO of this product over the past 4 months and they have BOTH leaked. It's a great product when it's working, but if it leaks - what's the point? I had them both professionally installed. The leaks are due to an internal component somewhere (not fixable) and were using 2x filtered water (likely not a hard water issue). Customer support was really easy to work with to get a replacement then refund, but I wish they would fix whatever allows these machines to leak (especially because there aren't many competing products). Highly recommend putting a drip tray in your under sink area to prevent the damage this product is likely to cause when it inevitably leaks.

After trying other ways to chill the water from my water filter, I was just not happy. So I decided spend the extra money and by this 'proper' water chiller that seemed intended for exactly what I wanted. I use it to chill the water from my 5-stage RO water filter to the dedicated faucet at my kitchen sink. It works great! I have this in my RV and have the chiller located in the 'basement' storage area with plenty of space around it to be ventilated. I have not tried it squeezed in the cabinet under the kitchen sink. I simply used extra 1/4 pipe to connect between the filter output and the faucet. It cools fast. If you were to run all the cold water through, it takes about 10-15 minutes to chill the internal tank completely. Having a look inside, I found one wire against a sharp metal edge. I added a small protection around that wire and relieved the tension on it. Beyond that, it looks well made and assembled. It was pricey but at least you get what you pay for. I recommend.

This product failed and flooded my kitchen, costing us thousands of dollars in damage. Now the manufacturer won't even respond to our emails. We're not asking them to cover damages. We just want a refund on their defective product. Here's the full story: I installed this product EXACTLY to the installation instructions. I even used a pressure regulator to bring my water pressure down to the recommended level (per the installation instructions). I checked every connection and hose many times to ensure no leaks. I then continued to check for leaks several times a day. And then several weeks after use, I noticed a leak happening from within the water chiller. I removed the front panel and could see where the water was dripping from. I took pictures and sent it to the manufacturer (Express Water). They agreed that it was defective and they very quickly shipped me a replacement unit. Once the new unit arrived, I switched it out with the original unit and kept all the connections the same and of course triple-checked that everything was secure and no leaks were occurring. I again proceeded to keep an eye on everything to make sure nothing was leaking. Everything was fine for a few days until I woke up to about an inch of water in my kitchen and water gushing out of the water chiller. Here's how I know this wasn't an installation error on my part: I killed the power to the water chiller and the water immediately stopped. This defective product has cost us thousands of dollars in damage to our brand new kitchen. Luckily, the flood restoration company we called was able to get to our house quickly which saved our cabinets. But our floor is completely ruined in a very large area because of the vast amount of water that made it's way underneath the floor boards. If that's not frustrating enough, here's the shady thing that Express Water did: they changed my ability to request a refund through Amazon. I have a screenshot of the Amazon order for this product stating that my purchase was eligible for a refund before October 22. I didn't start the return at that point because we were waiting to see if we needed to keep the product for insurance purposes (So I took a screenshot instead). On October 21, I logged in to start the refund process only to be shown a notice stating that my purchase was not eligible for a refund. They changed it on me intentionally. My only theory is they did this because they didn't want me to keep the replacement unit they shipped me and then get a refund from Amazon which of course would be stealing from them.

I used to own an Oasis under sink water chiller. That product apparently goes bad after a year and there are many reviews about it. I ordered this unit because of the price as well as some positive reviews. It arrived on time. I installed it in less than 30 minutes because I already had the pipes from the previous chiller. I have used this only a week so far and I like its operation. The water is chilled for drinking and the cooling fan unlike what some other reviewers have said comes on only when needed and in fact is very quite. I had 1/4 inch plastic pipes in place and this unit comes with proper fitting to utilize that or you can install your own pipe. The complains I have about this is that it comes with practically no instructions and unless you are somewhat familiar with basic plumbing it will be a little hard to figure it out. Otherwise it is a nice unit and I will update this review once I use it for a while. The other complain is that there is no knob for adjusting the water temperature on the outside. There might be one if you take off the cover but I have not found the need to do so yet.

I had previously owned an Elkay under counter chiller. It was slightly bigger and noisy. It failed, so I bought this chiller at about 1/3 the cost with the coupon. It is almost dead silent and chills colder than the Elkay unit. If you already have a line spliced into your cold supply, it comes with everything you need to install. Very happy with purchase. Time will tell if it is reliable.
