The Waterdrop G3P600 is a compact tankless reverse osmosis unit for fitting under the kitchen sink. Water passes through three twist-in cartridges – a sediment/carbon composite (CF), a carbon block (CB) and an RO membrane rated at 0.0001 µm – which together give eight filtration stages. A built-in booster pump delivers up to 600 gallons per day (about 1.6 l/min), so a glass fills in seconds without a storage tank, and the system sends one part of water to drain for every two parts of purified water.
Before installing, check that the cold supply pressure lies between 1 and 6 bar and the feed water is between 5 and 38 °C; the supplied adapter fits 3/8″ and 1/2″ cold-water connections, and a drain saddle and 1/4″ tubing are included for the waste line. The unit needs a nearby socket (100–240 V adapter) and about 46 × 14.4 × 45 cm of cabinet space. A 1″ hole in the sink or worktop is needed for the dedicated faucet, whose display shows water quality and when each cartridge is due (CF about 6 months, CB 12 months, RO 24 months).
Technical data on this page come from the manufacturer’s documentation (user manual and product page); where anything differs, the manufacturer’s documentation prevails. Waterdrop gives a 1-year manufacturer warranty on the system, in addition to the statutory guarantee.
