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.

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.

It works great but based on reviews I worry about the longevity. Easy to install
