Review: Great tasting water at your fingertips. - I finally got tired of going down to the local water station and filling up 5 gallon water jugs and broke down and bought a water filtration system for under the cabinet. I will admit, I had a little trepidation because I don’t generally like dealing with plumbing, but the installation for this system was extremely easy, and the instructions are very accurate and easy to follow. This WATERDROP unit fit very nicely under our kitchen sink. I even added a small water pressure tank as well as a mineralization filter and it didn’t take up half the space under our sink. Some things to consider when installing the system on your own or any system for that matter. You’ll need to know where your main water shut off is or at least have the ability to shut the cold water off under your sink because you will be tying into the cold water line under your sink. You’ll need an electrical outlet to plug the unit into, and you should be able to use the same one your dishwasher uses providing you have a dishwasher or garbage disposal. And a basic knowledge of plumbing will help as well but not necessary because the instructions are so easy to follow. All in all, it took me about three hours to get this installed mainly because I had to go down to the store and buy another fitting to hook up the refrigerator. We’ve had ours installed for about a month and a half to two months now and I enjoy being able to get freshwater right next to the tap at the sink. The water taste great and the filtering system seems to work very well on this unit. One thing to keep in mind, the water does not flow as fast as a regular sink faucet flows so be prepared that it takes a little bit longer to fill a glass of water up or a pitcher for example. If you think this will be a problem for you do some research and get a unit that has a faster water output. This particular unit has the digital display on the front, which will tell you when your filters need to be replaced. The manual says the filters have to be replaced every 6 to 12 months depending on the filter, but that could be different in your area based on how hard or soft your water is. As you can see from the picture below, the unit itself fits nicely underneath the sink, but all of the 1/4 inch tubing does look messy and I still need to get in there and try to make it a little neater. The tubing is somewhat rigid, so it doesn’t just lay on the bottom of your cabinet and kind of goes where it wants to go, so you may have to come up with a way to hook it to the wall or gently zip tie them together to make it a little neater. Also, it may seem like all of those plastic connectors wouldn’t work well or might fail, but honestly, once you push the tubing into those connectors, I’ve had no leaks whatsoever. Everything is nice and tight and secure. Plus it has the little blue locking rings that you put around the end of each connector to hold the tubing inside them so don’t be worried about that. All in all this is an excellent purchase and I’m really glad we got it. Having clean tasting water right from the faucet or the refrigerator is so much better than filling up ten 5 gallon water jugs twice a month. Don’t let this project seem overwhelming to you, with a few tools and the ability to read the instructions you’ll have it installed in no time.
Review: A good filter to clean water, great support - Several years ago, we upgraded our kitchen sink and added a water filter. After researching, we found the WaterDrop series with contained RO filters. The best part was its simple overall design. It’s a single unit with all the filters built-in, requiring only three connections to the water source and power. There’s no external pressure tank or tangled hose connections between components. Filters are easy to change with a simple twist to remove. We purchased a G3 unit, which worked well until we decided to upgrade for higher water flow. The G3 was rated at about 300-400 gallons per day. We then saw the WaterDrop G3P600 and felt it was an ideal upgrade since it used the same filters as our previous unit. We knew the RO filter would need replacing in a few months, so we waited until then to install the new unit. Swapping it out was very simple. In my opinion, the hardest part was installing the faucet. There’s rarely enough space behind the sink to reach up and work with the nuts that hold it in place. I completed the swap in about an hour, and everything was working fine—no leaks in the water lines. A few weeks later, my leak detector went off, and I noticed water under the unit. I contacted support since it was still under warranty. I emailed WaterDrop Customer Service, and Rosie C. responded. This prompted several follow-up emails to verify connections and other details. After trying various solutions, it became clear there was an internal leak and that a new or rebuilt unit was needed. Rosie then shipped a replacement unit to swap with the broken one. I waited for transportation and USPS, and the new unit arrived about a week later. Throughout the process, Rosie periodically checked in to see how things were going. As I write this, the unit has been running smoothly for about two weeks. I still inspect it daily and keep it on a sheet tray, just in case. I’ll probably keep it that way to catch any leaks early and avoid damage to the cabinet. In summary: I am very satisfied with the G3P600 and the support I received from WaterDrop in resolving the issue. I hope this unit lasts longer than the four years our original one served us. It’s a good product, offers excellent after-sales support, and is reasonably priced for clean water. Highly recommended for product value and support. Ed. Note: These are my personal opinions based on units I purchased. I have not been given a unit to test or reimbursed for my time.

This water system is great! This tankless design dispenses great-tasting water at your fingertips in seconds. The filters are amazingley easy to change with access in front of the machine. Also, we found it much easier to install than the system we were replacing it with. We had questions and concerns while setting it up due to our specific cabinet space configuration, and customer-service rep Doreen was quick to respond and offer help and advice. She truly seemed interested in keeping us satisfied with this product and with their service.
