Reverse Osmosis Instant Hot Water RO Filter System, 600 GPD, 2271L, Tankless, 2:1 Pure to Drain, Under Sink, TDS Reduction, Smart LED Faucet, WD-KJ600/WD-K6

All in all happy. Instant Filtered hot water is very useful TDS started ~20 & went up to ~50 after ~6 months. A replacement filter returned it to ~15 & rose to ~38 after 11 months. Another issue was E06/E05 errors ~ 20 months in. I contacted Water drop & they agreed to ship a replacement if I paid £90. The replacement came with a new filter so was les than a filter for a new machine. whilst I was miffed at paying £90 the prospect of paying less than a new filter around the time it was due to replaced & getting a new machine made sense. Didn't take long to swap the old for the new.

We originally purchased the Waterdrop K6 in March 2024. After more than two years of use, the unit unexpectedly developed E06 and E05 error codes and the hot water function stopped working. Although the warranty had already expired, we contacted Waterdrop hoping they could at least help diagnose the problem. I was genuinely impressed by the level of customer service. Becky and the support team replied promptly, patiently reviewed the photos and videos we provided, answered every question thoroughly, and never made us feel like we were simply out of warranty and on our own. They eventually offered a very reasonable replacement programme and sent us a brand-new K6 unit complete with new filters and a new one-year warranty. The replacement arrived quickly, installation was straightforward, and the new unit has been working perfectly. Excellent communication, professional support and a solution that exceeded our expectations. It’s rare to receive this level of after-sales service nowadays, and it has given us much greater confidence in the Waterdrop brand. Highly recommended.

Easy setup, works great. Filter clean from 240 tap water to 15, but screen on tap show 7. And also before was worse tap water around 340 and result was the same

This is the best thing I've ever bought. I know of no other with hot water and reverse osmosis. It looks very slick too. I'll be buying one for xmas for my son who buys bottled water non stop. I did purchase the separate filter to add back essential minerals which the filter may have removed along with the nasties. I had an issue at one point and Doreen in customer services gave excellent service. Thank you.

Bought for elderly mother. In last 2 months hot water did not turn off for several minutes despite pressing off button. Customer service won't do anything unless they see a video of it. How do I ask my 80 yr old mother to take a video of an intermittant fault by herself. Wouldn't get if you have v.young/ old people in the house.

It purifies water thoroughly, and while the initial taste was slightly bitter due to extensive TDS removal (expected with any high-quality RO purifier), adding a remineralization filter made the water wonderfully sweet and enjoyable to drink. Even my dog prefers this water! After experiencing this, tap water just doesn’t compare anymore. As a doctor, I installed this to ensure better health, especially with recent news suggesting that 70-80% of UK water might be unfit for consumption. The smart tap is a standout feature—sleek, efficient, and definitely an eye-catcher. My family and friends were so impressed after tasting the water and seeing the setup that many have installed the same system. Highly recommend it for anyone serious about clean and great-tasting water!"

I faced a technical problem after using the machine K-6 for more than five months, after submitted the failure symptoms and photo, their CS especially Krystal, who was really helpful. Within 24 hours she helped and provided a solution for me. Appreciate her support and other CS team. Although facing issue after five months is not good at all but the CS team from WaterDrop help a lot for future recommendations to others.

I've been using this for just over a month now. It was very easy to install and I've had no problems with it. The water tastes great and the flow rate is very good. The hot water function is very handy, and having come from a traditional RO system, I definitely would not want to go back. The tap is very small, so is definitely not discreet, but if you don't mind the look of it then it's definitely worth the investment

Plutôt pratique, mais il est un peu bruyant quand il se remet à produire de l’eau après usage

Ottimo prodotto per chi come me non vuole essere vincolato ad un abbonamento mensile per avere acqua filtrata . Possibilità di avere acqua temperatura ambiente o calda pronta per un Thè. Lo consiglio

Muy contenta con el producto. Cambio el sabor mucho y la calidad del agua. Muy recomendable.

We are absolutely thrilled with the Waterdrop K6 Reverse Osmosis System. It has completely transformed how we use our kitchen. Having instant boiling water and filtered cold water from a single, sleek tap is a massive convenience—we’ve practically retired our kettle! ​The 600 GPD capacity is impressive; the flow rate is fast and steady, so there’s no standing around waiting for a glass to fill. The tankless design is a huge space-saver under the sink, leaving us plenty of room for storage. ​ The Smart LED display on the tap is a fantastic touch, providing real-time TDS (Total Dissolved Solids) readings so we know exactly how pure the water is. The 2:1 pure-to-drain ratio is also much more efficient than older RO systems we looked at, which makes it feel like a more sustainable choice. ​ Overall, it’s an amazing product that delivers on every promise. If you want high-quality water and the luxury of instant heat, this is worth every penny. ​ Pros: ​- Instant Hot Water: Perfect for tea, coffee, or speeding up cooking. ​- Space-Saving: Tankless design fits perfectly under the sink. ​- High Efficiency: Excellent 2:1 pure water ratio. - ​Smart Monitoring: LED display makes it easy to track filter life and water quality. ​Cons: - ​Installation: Requires a bit of DIY confidence or a plumber (but well worth it). - ​Power Requirement: Needs an under-sink power outlet for the heating and pump.

Bruit énorme, j'ai contacté le service après vente mais aucun réponse. Aucun vrai mode d'emploi seulement quelques pages en lignes.
