Express Water Residential Undersink Water Chiller Cooling System for Water Filters/Reverse Osmosis RO Systems

If you want the luxury of a commercial water cooler hidden right inside your kitchen cabinets, this is the way to do it. I paired this Express Water Chiller with my 6-stage Reverse Osmosis system, and it has been a total game-changer for our tap water. Water Quality: 5/5 The stainless steel internal components are fantastic. It chills the water perfectly without introducing any weird metallic or plastic aftertaste. It preserves the exact crisp, clean taste of my highly purified RO water and just delivers it ice-cold. Clarity of Instructions: 5/5 The manual was straightforward, well-illustrated, and made integrating this unit into my existing under-sink setup completely foolproof. I didn't have to guess about any of the connections. Value for Money: 5/5 Having on-demand, ice-cold filtered water right at the sink saves me from ever having to buy expensive bottled water, and it completely eliminates the need for a bulky, freestanding water cooler taking up floor space. It is worth every single penny for the convenience alone. Ease of Installation: 5/5 The included 1/4" quick-connect fittings are an absolute lifesaver. It took just a few minutes to splice the chiller right into the water line running between my RO tank and the dispenser faucet. No professional plumbing experience needed! Size: 5/5 At just over 7 inches wide, it is surprisingly compact. It tucked neatly under the sink right next to my RO system and tank without hogging all my under-cabinet storage space. The built-in cooling fan also has plenty of room to breathe. Water Filtering: 5/5 While this unit is a chiller rather than a filter itself, it is the ultimate companion to my heavy-duty filtration setup. It handles the highly purified, remineralized water flawlessly, acting as the perfect final step to give me that premium, bottled-water experience straight from the tap.

Worked really well for a couple of weeks, then it started leaking. Unfortunately it was out of return window, (we ordered while we were moving into new house and did not install it right away) I attempted to contact the product’s customer support, through the link in Amazon app. The recording continues to tell you that the wait time is 1 minute, this recording is repeated several times until you’re disconnected. And of course the obligatory satisfaction survey follows…asking you to rate them, as if they had answered and had been helpful. I initially had given this product a 5 star rating but short operational life and absence of customer support makes me rate it as a DO NOT BUY.

One thing I missed when I ordered this is the water pressure requirement. Max water pressure is 50psi. After dealing with a leaky 1/2" regulator for days, finally found a tiny 1/4" ptc regulator and bought a ptc pressure gauge, both fairly cheap and got it going. It does require a filter, which I got on Amazon, also ptc. The instructions were adequate. With the addition of a fountain spigot we now have cold, filtered water out of a fountain that drains to the kitchen sink. The water temperature is not quite enough to give you a brain freeze, but it can be adjusted inside the box. This takes up a lot less space than a free standing fountain, since the space under the sink is essentially wasted anyway.

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.
