Waterdrop G3P800 800 GPD Reverse Osmosis Water Filtration

High-capacity reverse osmosis system

The Waterdrop G3P800 is a tankless reverse osmosis filtration unit rated at 800 gallons per day. It is designed for large households that need a continuous supply of purified drinking water without a storage tank. The system uses a 10-stage filtration process verified by SGS to reduce PFAS, fluoride, heavy metals, salts, large particles and radioactive substances. It holds IAPMO R&T certifications against NSF/ANSI 42, 53, 58 and 372 for contaminant reduction and lead-free materials.

Efficient operation with low waste ratio

The unit achieves a 3:1 pure-to-drain water ratio, meaning three parts filtered water are produced for every one part sent to drain. This ratio is enabled by advanced dispensing technology that manages flow without a pressurised tank. The smart faucet includes an integrated LED with a 50-year rated lifespan that activates automatically when water flows, providing real-time TDS readings without adding noise or heat to the kitchen environment.

Compact tankless design for simple installation

A tankless chassis saves under-sink space and frees up room for other storage. Installation requires two holes: one for the dedicated RO faucet and one for the drain pipe connection. The system suits builders who cannot accommodate a bulky storage tank, but it is not suited for buyers who need a gravity-fed or non-electric filtration method.
