WaterDrop G3P800 Tankless RO System with UV Sterilizing Light Review

Product Overview

When I first heard about the WaterDrop G3P800 Tankless RO System with UV Sterilizing Light, I was curious if it could deliver on its promises of high-capacity filtration and advanced safety. As someone who values water quality and convenience, I wanted to see if this under-sink RO system was worth the investment. The 800 GPD flow rate, 10-stage filtration, and UV light sounded ideal for health-conscious families or anyone with higher daily water needs. After several weeks of daily use, focusing on installation, maintenance, and real-world performance, here's my hands-on review.

Key Features & Technology

• •Tankless design provides a continuous flow of filtered water and frees up under-sink space in my kitchen.
• •Integrated UV sterilizing light adds protection by targeting bacteria and viruses-reassuring for families.
• •10-stage filtration system removes a broad range of contaminants, including chlorine, heavy metals, and particulates, resulting in noticeably cleaner-tasting water.
• •Smart faucet display shows real-time TDS and filter life, making it easy to monitor water quality and know when to change filters.

Performance Testing Results

The G3P800's high flow rate is a game changer. Filling pots or bottles is quick-much faster than my old RO system. Water tastes crisp, with no chlorine or metallic aftertaste, and my coffee is noticeably better. The UV sterilization runs quietly in the background, and knowing it's there gives me peace of mind. TDS readings from both the smart faucet and my handheld meter are consistently low, confirming strong filtration. The 3:1 pure-to-drain ratio means less water waste, which I appreciate for environmental and cost reasons. Even with guests over and heavy use, the system keeps up without lag. The only time I notice it is when the faucet display reminds me to change a filter-a helpful nudge.

Installation Experience

Installing the G3P800 took me about 90 minutes. The instructions are clear, and labeled parts help a lot. Drilling a hole for the smart faucet might intimidate some, but the included template made it straightforward. The tankless design means less bulk, so I didn't have to rearrange anything under the sink. Connecting water lines and the drain saddle required some patience, but the color-coded tubing helped. The UV light and power supply add a few steps compared to basic RO units, but the process is manageable for anyone comfortable with basic DIY. If you're not handy, professional installation is worth considering.

Daily Use & Maintenance

Maintaining the G3P800 is simple. The smart faucet display counts down each filter's lifespan, so I never have to guess when to replace them. Swapping filters is tool-free-just twist and pull. The UV lamp needs periodic replacement, which is an extra step, but it's straightforward and well explained. I set a calendar reminder for the UV lamp based on the system's recommendations. The system flushes itself after filter changes, so I don't have to run gallons of water manually. I wipe down the exterior every few weeks, and so far, no leaks or drips. Overall, maintenance is minimal and fits easily into my routine.
