Waterdrop G5P700A Alkaline Mineral pH+ Reverse Osmosis Water Filter, NSF/ANSI 58 & 372 Certified, 700G Reverse Osmosis System, 8 Stage RO Water Filtration System, 2:1 Pure to Drain, Smart LED Faucet

Water from this water drop tankless unit tastes fantastic. I was tired of lugging those 5 gallon jugs around, so I figured it was time to invest in a system. I was a little hesitant about the tankless RO systems due to a family member having one that cost about 3x as much, is extremely loud, and the water doesn't taste that great. This is quiet when operating, has decent flow from the spout, and the led screen on the spout is a nice feature. It also doesn't take up very much space underneath the kitchen sink, unlike the standard tank style models. Filter replacement also is also easy, which is a bonus. Comes with everything to install it, but I opted to use John Guest fittings instead. Install is simple with all the connections labeled. Seems to have been designed for any diy person to be able to install. Hopefully it's reliable and holds up well.

I live in an area that tests at 205 ppm, it's able to filter it into clean water that tests at 3ppm. The water tastes great, has worked solid for 6 months. I never have any issues with it keeping pressure capacity. Designed well, filters are super easy to change. Great value!

6-month Update: The RO continues to perform excellently, with no leakage or unexpected issues since installation. We are preparing for our first CF filter replacement; the advisory beeps are audible but not excessively loud (RO unit is installed in a closed-door under-sink cabinet). We also added our refrigerator ice maker to our Waterdrop system, and it seems to be performing well. I believe this RO is a far better system than our old one, and recommend it. ~~~~~~~~~~~~~~~~~~~~ Original Review: We purchased and installed this RO filter almost a month ago. Here are our impressions: - The taste of the water produced is excellent, much better than the old system this one replaced. - We experienced no leakage after installation, again an improvement. - It has a much smaller under-sink footprint than our old one. - Filters are easy to remove/replace. - Installation was easy, especially with multiple videos, instructions, and diagrams. - The unit feels very well put together, and all the parts were there. - It makes some normal noise during operation, but not so loud that it is distracting or annoying; our refrigerator ice maker is about the same level. I don't see it as a detractor. - Customer Service: This is where Waterdrop really shined in my family's eyes. Our Customer Service Rep, Krystal X, responded within hours of our initial request for help, and on a weekend to boot. She took the time to gather pertinent trouble information, get it to her engineers, and had a response and had parts on the way almost immediately. It is clear she and Waterdrop care about the quality of their product and taking care of their customers, and stand by their product to fix any concerns immediately. Krystal took personal ownership of our ticket, and saw it through the process to final resolution. I feel like this is a level of customer service that so many businesses simply don't deliver these days; in my opinion she would be an excellent trainer of other reps, or a great supervisor/manager. Please pass on our thanks to her, Waterdrop! As mentioned above we had a small issue, but since it was resolved and didn't involve something we saw in other reviews, I think it may be a one-off circumstance that was satisfactorily fixed by Waterdrop. I do know we are happy with our improved water quality. Thank you!

I replaced my old tank style RO system with this tankless RO system. Overall, I am pleased with this RO system. Sort of easy to install and the water flows and does not run out like my old tank RO. The instructions were easy to follow and I like how much smaller this tankless RO system is compared to my old tanked RO system. Great value compared to other company tankless RO system. Right now I am flushing my system but the water had low TDS even before flushing. The only bad things was the tube is bigger than my previous RO system so I had to use the included faucet which my wife hates since it is not gold. I checked the Waterdeep website but there is no gold nor black faucet I can change. The tubing was a tad inflexible but I was able to install them. Once the flush is done, I expect the water to have a clean taste with no odor.

This is a great RO system and is priced very well compared to similar filtration systems. This Waterdrop G5P700A unit was replacing an older tank RO system that we’ve owned for over 7 years and which had 4 filters. One of the reasons I selected this Waterdrop product was it only entails 2 filter replacements, but still having 8 stages of filtration. (One filter change every 6 months, and the other primary RO filter has a lifetime of 24mo). The faucet installation was the most demanding task, as needed to enlarge the hole in the granite countertop to aid in getting the faucet through. All other steps for installation were spelled out in the instruction sheet and easy to follow. I really like the black matte look on the RO unit even though it’s under my sink and not visible to everyone. The faucet which has a brushed nickel finish is an ideal match to my main kitchen faucet and the RO faucet has a very modernistic and stylish look. The electric pump that runs when the faucet handle is opened is relatively quiet. After using this system a few days you don’t even notice or are aware of the sound when the pump runs. Water stream is constant and okay, but slightly less flow than my old tank RO system. Perhaps takes another second or so to fill 8oz cup, in comparison. I’ve only had this RO unit installed and functioning for 3 months now, but everything appears to be operating great and the water taste is perfect. No issues so far with leaks or faucet dripping as other buyer reviews have mentioned. We currently are impressed with the product and hoping it will continue to operate flawlessly and provide excellent tasting water for many years to follow. ** Updated review ** After using this RO system for almost five months now, I'm updating my initial review. On the positive side, my independent testing with a separate third-party TDS meter confirms that the unit is providing good quality filtered water. However, a significant concern has arisen regarding the accuracy of the smart faucet's TDS display. The smart faucet consistently only displays a reading between 15 and 18, a number that does not match the actual readings I have verified using a stand-alone TDS meter. As an example: When water remains idle in the alkaline filter for an extended period (e.g overnight), the TDS will be initially higher upon dispensing. This effect holds true as my test sample with a TDS pen has been as high as 225 after inactivity. However, the TDS value in the faucet display never changes or fluctuates when turning on the faucet. In my case, the faucet display should be detecting and showing that higher mineral content, before dropping back down to a more normal range after about 15-20 seconds of purging. When I reached out to Waterdrop’s customer support about this issue, they maintained that the device was functioning "normally" and offered no solution or replacement. I believe this meaningless value on the faucet display indicates a defective sensor or faucet, and their lack of support has left me with a complete loss of confidence in the product's smart features. A properly functioning display should alert the user to any increased dissolved solids (TDS) to insure you are receiving the best quality water.

This unit functions well with just a slight humming sound when dispensing water. The water tastes great. The installation was very straight forward, I did however encounter a couple of challenges that were perhaps unique to my environment which I will detail in sections A and B below. I do appreciate the assistance I received from the support agents for this product to resolve these issues. Installing the small "pure water" faucet was easy since I already had a 1 an 1/4" hole (this was the maximum hole size for this faucet.) Installing the drain connection was easy since it just requires drilling a small 1/4" hole in the existing drain pipe, and clamping on the fitting. Section A. The unit comes with a "Y" adapter for the water supply, 1 side for the existing (large) faucet flow and the other for the plastic tubing to supply the filter system. I was replacing an existing water filtering system, so I already had a dual water outlet shutoff valve in place. Initially I tried connecting the "Y" adapter to this dual water outlet valve and capping the extra outlet, but it caused the unit to beep and not function, however, once I cut off the existing dual outlet valve and replaced it with a single outlet valve, and then connected the "Y" adapter to that it worked fine. Section B. I had an existing electrical outlet under the sink that I intended to use for powering the filter system, the problem is both of the plug-in's were switched with the existing garbage disposal (yes, I should had expected this,) so it wasn't possible to switch the power for the garbage disposal and water filter system separately. I contacted the support number and they suggested adding a remote control outlet plug to control the garbage disposal separately while leaving the original switch in the "on" position for the filter system. I found a good inexpensive remote control outlet plug on Amazon in the "Zoiinet" store. Fyi, I also saw another posting stating that they were able to plug the filter system into the dishwasher outlet for this, but it would had been difficult routing the cord in my configuration. I'm pretty sure I would had encountered these issues with any other powered system I might had purchased, but with the support provided I was able to complete the installation successfully.

The product has been exactly what I expected and hoped it would. The installation is fairly straightforward, you have to work in the space under your sink with water pipes so I won't say it's an easy job but the smart connectors and adapter supplied by Waterdrop make it as easy as it can be! The instructions are good, not great, I paid careful attention and was able to get it right first time. I bought the Alkaline version (the G5P500A not the G5P500) - that was slightly confusing because the product packaging doesn't indicate whether the unit you receive is a G5P500A or a G5P500 - and there is a single product listing which shows two different colors, but in fact one "color" is the G5P500A and the other is the G5P500. I contacted Waterdrop Support to confirm that I had received the correct product and they pointed out that the filter in the G5P500A is very clearly marked WD-G5P500A-CF. They were super helpful and understanding because I had also ordered a replacement filter and had not ordered the right one for the G5P500A - I was able to return the wrong one and get a replacement with no extra cost. So I'd say the two different versions of the G5P500 could be more clearly distinguished in the product listing - but Doreen in customer support went above and beyond to clear things up for me. Most important of all I'm getting great water quality from the unit (~22TDS) - I am on well water with an iron filter that makes the water good for household use but I wanted to purify that further to give me good quality drinking water. The unit makes a whirring sound when it's in use but it's not too loud. There is a brief delay after you turn on the tap - but I expected that because this is a tankless unit, which is what I wanted - then the water flows at a good rate - I haven't timed it but I'd guess about 90sec to fill a coffee pot. I haven't had to change filters but I took the filter out to check the model and it easy to remove and put back. Overall I'd recommend the product and customer support. I also got an excellent price during Prime Days!

This is a great filter solution for a decent price. I got the extra bladder to connect to my refrigerator. And I had to get various connectors to connect my 1/4 inch to 3/8 inch and back to 1/4. In one case a three way 3/8 that I then attached a 3/8 short pipe to be reduced to 1/4 to go into the bladder pump. But overall this was a relatively easy install with a lot of connections. I also had to drill a hole in the corian sink. Water tastes great. It’s faster at the faucet than from fridge but I can work with that.

I haven't installed this unit yet, the 5 stars is for customer support. I wanted to share the information I received for fellow cat people because it could save your cat's life! Unlike humans, cats require a slightly neutral/acidic Ph (6-6.5). If their Ph balance becomes too acidic or too alkaline, they could develop urinary stones and need to be put on a prescription diet and/or have surgery (in the best case scenarios). I called customer support to inquire if I could simply remove the alkaline portion of this filter for when I'm filling my cats' water dish. She explained that the unit wouldn't work with one of the filters removed, but gave me a brilliant workaround. Here's the plan: I will purchase a replacement filter that's NOT alkaline (similar model number but without the A; the non-alkaline filter for this unit is G5P500-CF), then switch out that filter when I'm filling my cats' dishes. When I'm done using it, she advised me to store it in there refrigerator to prolong the shelf-life. She said that I will need to retire that filter after 3 months, whether it's all used up or not. While I wish it would keep longer when not in use, I am thrilled that the company offered this workaround solution. I can't imagine too many other companies would be willing to be creative and flexible like that. Their kindness and willingness to help me find a solution was impressive. Waterdrop, if you're listening, thank you for helping meow-t :)
