Waterdrop G3P600 tankless under-sink reverse osmosis system
The Waterdrop G3P600 is an electric, tankless reverse osmosis system for under-sink installation. It includes a smart display faucet and is designed to provide filtered water through a dedicated RO faucet without a storage tank.
Key features
- Listed 8-stage filtration: The current product listing describes an 8-stage reverse osmosis system. Specific contaminant-reduction claims should be matched to the applicable performance report and test conditions.
- 600 GPD listed production rate: The listing states a flow rate of 0.42 gallons per minute and up to 600 gallons per day. Actual performance depends on feed-water pressure, temperature, water quality, and filter condition.
- 2:1 pure-to-drain ratio: The listing describes two parts filtered water for one part wastewater. Actual ratios can vary with water conditions and operating conditions.
- Smart display faucet: Displays total dissolved solids and filter-life information. TDS readings can vary with local water quality and are not a complete measure of water safety.
- Tankless design: Uses an under-sink format without a storage tank and includes self-cleaning and holiday-mode features as listed.
- Filter service indicators: The system and faucet provide filter-life reminders according to the current listing.

Installation and water requirements
This is an under-sink system that requires electricity, a nearby drain connection, and connection to a compatible water line. The listing states that a 1-inch countertop hole may be needed for the dedicated faucet unless an existing suitable hole is available. Included components are listed as the system cover, smart display faucet, RO, CF, and CB filters, three PE pipes, T-fitting, drain saddle, lock clips, and power adapter.
The manufacturer does not recommend using well water with this system or connecting it to a salt-based softener, refrigerator, or ice maker without confirming compatibility and pressure requirements. Review the installation manual before drilling or connecting the system.
Before ordering
Confirm the current certification documents, tested reduction claims, feed-water pressure range, tubing sizes, faucet finish, included parts, installation clearance, filter costs, and warranty terms. Use only compatible Waterdrop components where required by the manufacturer.
