Waterdrop G5P500A RO system experience
I purchased the G5P500A unit back in January 2026 and installation was straightforward. The hardest part was needing to drill a new hole into my quartzite countertop, which was fairly easy. I also needed to drill a hole into the drainage pipe for the waste water (red tube). Aside from that, all the needed accessories are included with the product. After completely installing the unit, I never had any leaks. The water tastes great and clean. I tested the water with a TDS meter with my tap water reading 450ppm and 50-80ppm with the filtered water. I also tested the pH which was in 8-9 range. Fast forward to July and I purchased a CF filter here on Amazon, from Waterdrop. The CF filter needs to be replaced every 6 months and the RO filter every 24 months. After I replaced the CF filter, that was when the problems started. Immediately after installing the new CF filter, there was a huge drop in the water pressure and at times almost completely stops. I reinstalled the filter multiple times and attempted to troubleshoot by resetting the unit, checking all lines with no luck. I figured it must have been a bad filter. I then requested for a replacement filter from Amazon and was sent a new one. This new one had a slightly better result but still had a significant drop in water pressure. I then reached out to Waterdrop customer service. After some troubleshooting and explaining the situation, they sent me another CF filter which was ALOT better than the ones purchased on Amazon, but still with a noticeable drop in water pressure. Compared to videos I had when I initially installed the unit, the water pressure was only around 80%. I notified Waterdrop of this concern, and they sent me a new overall unit to replace my old one. I now have a brand new unit installed and the water pressure is back to normal. I performed the same tests and the TDS and pH are all as expected. Despite the issues I had when replacing the CF filter, Customer Service came through with flying colors. Doreen was the rep that assisted me throughout the whole process and was nothing short of excellent. The assistance provided was smooth and reassuring that they have great customer service reps. She was outstanding and helped me resolved the issue very quickly. I love this RO unit. I got mine when it was on sale and has been amazing. Next time I might not purchase the filters from Amazon and will just go through the Waterdrop website instead since their pricing, the last time I checked, were pretty much the same. I don't know if I was just pretty unlucky and received 2 faulty filters. Despite the issues I went through, I would still highly recommend this product.
