Review: Waterdrop - Excelkent Reverse osmosis products and great customer service - ⭐⭐⭐⭐⭐ Exceptional Product and Outstanding Customer Service I purchased the Waterdrop G3P800 and have been very pleased with the quality of the water it produces. It provides exceptionally clean, great-tasting water while using significantly less wastewater than many other reverse osmosis systems I have considered. Overall, I have been very happy with the product. Unfortunately, after replacing the RO filter, I experienced an issue where the wastewater pump continued running and the unit would not function properly. I contacted Waterdrop customer service, and I was fortunate to work with Doreen. Doreen provided truly exceptional customer service. She patiently worked with me through the troubleshooting process, including various power resets, on/off procedures, and faucet adjustments. When those steps did not resolve the problem, she stayed in contact with me throughout the entire replacement process. What impressed me most was how thoroughly and professionally she handled everything. Doreen explained the replacement procedure, kept me informed about shipment timing, followed up to make sure I received the replacement unit, and provided the necessary instructions for setting it up. She even made sure I understood the next steps after receiving the new unit. The replacement process was remarkably easy, and the cost to me was minimal. The replacement unit also came with three new filters, which was an added benefit. Doreen was consistently courteous, efficient, knowledgeable, responsive, and informative throughout the entire experience. She took ownership of the problem and stayed involved until everything was resolved. That level of customer service is unfortunately rare these days and deserves recognition. I would highly recommend the Waterdrop G3P800, not only because it produces exceptionally clean water with very little wastewater, but also because Waterdrop stands behind its product and has representatives like Doreen who genuinely care about their customers. Excellent product, excellent support, and exceptional customer service from Doreen. Five stars without hesitation! ⭐⭐⭐⭐⭐
Review: Well Designed, East to Install, Great Tasting Water - We live by the sea in an old community in an area with very high particulates in the water system. The water also smells like chlorine. We have always bought bottled water, but with the Pandemic, our grocery load started to become unmanageable as we cut down on the number of trips we made to the store. We started to drink the tap water and almost immediately decided it was time to try out a water filter. RESEARCH I did a lot of investigation, and by a long shot, the WaterDrop products represent the best designs on the market: - the forward-facing filters are as easy to replace as a refrigerator filter. - the tankless design means you don't lose much undersink space (Image1) - the tankless design also means there's no opportunity for bacteria to grow in the holding tank - the smart faucet (the led ring around the base) conveys the state of the filters - blue is good, yellow means you're due for a change and red means you should change a filter immediately - the WD-G3 display not only tells you the state of the water in Total Dissolved Solids (TDS), but also shows you the state of each of the filters (blue/yellow/red) so you know which one to order. - the brushed nickel finish matches our faucet and looks great (Image 1) - the 12 second time-to-fill an 8 oz glass is good Everything about this unit screams "quality". The instructions are simple and easy to follow. The 800 number is listed on the cover of the installation guide. Each part feels solid and well-made. INSTALLATION There is one challenge that most homeowners will probably face to using this unit -- it requires power under the sink. I had a socket under my sink that the garbage disposal was plugged into. I assumed (you can see where this is going!) that as is traditional, the upper socket was wired to the disposal switch and the lower was always hot. Unfortunately, living in an older home, this was not the case, so I had to replace the socket with a split/switched/always hot one. Our garbage disposal unit is huge, and our sink is in the corner of the kitches with one small door, so it needed to be removed to facilitate the install. Between the disposal deinstall/reinstall and and the rewiring job, installation took me all day. HOWEVER - The actual installation of the Waterdrop unit was approximately 40 minutes of this, so plan accordingly. I had one minor issue with the waste pipe connection, which is designed for 1.5" pipe (we have 2" pipes, but the pipe coming out of the garbage disposal was 1.5" with just enough space to connect the waste line). All of the lines are thoughtfully unique - there are two white lines, but of different sizes (one goes from the water source, one goes to the spigot) and the waste water is red, so you can't get confused. The connections are all pretty easy, although you should pay attention to the "Push the locking ring" instructions so you don't accidentally break one of the shipping plugs when removing them. The locking ring collars are a bit fussy and require a needle nose pliers to install. Other than my own personal challenges of a small under-sink space and the electrical issue, the installation was a breeze. WATER QUALITY So, the big question -- does it work? The answer is YES! See the second the image. I used an independent water meter to measure the TDS. On a sample from a bathroom spigot I got 99. This is pretty typical, we run around 90 to 120. Measuring the water from the filtering system shows 12. The reading on the front of the unit showed in the mid 70's during startup, but now shows 5. Given the somewhat wonky nature of water testing, I'm good with these numbers even though they differ slightly. The WD-G3 reduced the TDS in our water by an order of magnitude. This is exactly what you would expect from an RO system that should filter out about 90% of all TDS. This translates to a better tasting, safer glass of water, which it produces in about 12 seconds (8 oz). Not only does the water taste better, our coffee and anything else we used water in also tastes better. While the difference is not as evident at room temperature, you can really tell the difference in a side-to-side test of chilled water. We tested tap vs filtered vs Poland Spring bottled. At room temperature, they are all pretty much the same, with Poland Spring being slightly saltier. We tested the TDS on Poland Spring and it was at 41, confirming that there's some mineralization going on there. In chilled form, the filtered tasted the best, with Poland spring second and the unfiltered third. (And yes, to answer your question, my wife is now laughing at me because of my obsession with metrics and blind taste tests) FILTER REPLACEMENT/CUSTOMER SERVICE As some other reviewers have notes, the "CF" filter seems to be in very short supply and cannot even be purchased on the Waterdrop site. I contacted Waterdrop customer service who responded (on a weekend!) that the filters will be back in stock at the end of this month. SUMMARY Pros: - Does what it says, reduces TDS by a factor of 9-10 - Produces clear, clean water - Interface is intelligent and intuitive - Tankless design saves space and eliminates post-filter bacteria issues - Looks great - Responsive customer service Cons: - Requires un-switched power under the sink - The CF Filter replacement is currently unavailable. Recommendation: The CF shortage is worrying, hopefully Waterdrop will be able to solve this issue. It's a Pandemic so I'm willing to give them some leeway in supply chain challenges. I decided to take the plunge anyway and given the alternatives, this is still the best unit on the market.

### ⭐⭐⭐⭐⭐ Excellent product and customer service - Clean water with great taste
*by C***E on August 12, 2026*

Update: After changing a filter recently, contacted Waterdrop Support because I had some strange readings. They responded super fast and helped me work through issues. It turns out I didn't flush the system properly after the filter change. For what it's worth, the TDS (total dissolved solids) reading on the Waterdrop are extremely accurate. The water quality is excellent. Our tap water is good, but the RO water is so much better. I thought the lack of minerals would make it taste "off" but that is not the case. It tastes like pure bottled water without the cost and waste. I bought my system a year ago to install in my remodeled kitchen. It fits perfectly under my sink and has worked perfectly through several scheduled filter changes. Customer service responds within a day and my questions are answered clearly. The filters are not cheap, but factoring in quality, convenience and overall cost, it's a bargain.
