Waterdrop G3P800 RO for High Demand Drinking Water

The Waterdrop G3P800 is a high capacity tankless reverse osmosis system designed for fast under sink drinking water filtration. It pairs 800 GPD output with a ten stage filtration path, a smart display faucet, and a 3:1 pure to drain ratio.

Best suited for: Larger households and high demand kitchens that want faster dispensing, smart water status, and compact tankless installation.

Why choose this system

Choose the G3P800 when you want more output than the G3P600 plus a higher pure water ratio and an expanded filtration design.

How this benefits your home

  • Cleaner tasting, lower TDS water: Ten stage reverse osmosis filtration supports a more refined drinking water supply for beverages, ice, and cooking.
  • Less waiting in a busy kitchen: The 800 GPD capacity is designed for higher household demand and faster bottle, glass, and cooking pot filling.
  • Less water sent to the drain: The 3:1 pure to drain ratio produces three parts filtered water for each part of wastewater, helping reduce operating waste.
  • Fewer bottled water purchases: A high capacity supply at the kitchen sink can reduce reliance on single use bottled water and its recurring cost.
  • Maintenance without guesswork: The smart faucet shows TDS and filter life so cartridges can be changed when needed instead of too early or after performance declines.
  • More usable cabinet space: The tankless layout avoids a bulky storage tank and leaves more room beneath the sink.
