Waterdrop G3P600 Reverse Osmosis System, 8 Stage Tankless Reverse Osmosis Water Filter, NSF/ANSI 42 & 58 & 372 Certified, Under Sink RO System, 2:1 Pure to Drain, Smart LED Faucet

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.RESEARCHI 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 goodEverything 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.INSTALLATIONThere 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 QUALITYSo, 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 SERVICEAs 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.SUMMARYPros:- 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 serviceCons:- 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.

bonjour très facile d’installation et tien peu de placele fonctionnement est bien bonne pressionje le recommandesalutations

First of all: installation and maintenance is very easy. Here in Surrey this filter gives me 15 TDS which is not perfect for aquarium. But the worst thing is that the TDS meter is a joke. I have my own TDS meter and it is in line with this build in for the most of the time, besides when filter needs to be replaced. Inbuilt TDs meter was showing 16 ppm, mine 300 – tap water is here arround 350! After exchanging the CF filter, AND flushing it was lower and lower TDS measured by my TDs meter, but the inbuilt was showing 15 all the time !!!! Moreover, I assume these filter change alarms are automatic – like programmed for a period of time .. 🙁 I will buy a PROPER RO filter after moving to another house. This one is OK for drinking. Build quality 5/5, ease of use 5/5. Filtering 2/5. Overall 3/5. Not recommended for aquarium use.

Go for it. We are very happy with the Waterdrop system. We wanted a model without a tank, and the flow rate is excellent. We no longer have to wait a long time to fill our water containers, and the digital indicators make it look modern and up-to-date. The water tastes great, and we no longer have the headache of changing filters frequently.So far, I haven’t experienced any leaking problems with my system, which I’ve seen mentioned in some reviews. My plumber installed it for me, and he even asked where I purchased it. The main reason I chose Waterdrop was because of a comprehensive water test I saw in a YouTube review, which showed great results. I wrote to the reviewer because I couldn’t buy the system directly from her site, despite her having an Amazon link to other water systems but not for Waterdrop. Hopefully, she will add it in the future since returning items on Amazon is easy. Hope this review helps, I wanted a good water filter system in the middle price range.
