Know before you buy
Not at all. The G3P800 features an 800 GPD high-capacity flow rate, which allows it to fill a standard cup of water in just a few seconds without needing a bulky storage tank.
This ratio indicates that for every four gallons of water processed, three gallons are purified for drinking while one gallon is sent to the drain. It is significantly more efficient than traditional RO systems, which often waste much more water.
The UV sterilization is integrated into the system to provide an extra layer of protection against bacteria. It activates automatically to ensure your water remains pure and safe as it passes through the final stages of filtration.
The smart faucet included with the system monitors your water quality and filter life in real-time. It will provide visual alerts when a filter change is necessary, and the filters themselves are designed for a quick 3-second replacement process.
Yes, the G3P800 requires an electrical connection to power the high-flow pump, the smart monitoring system, and the UV sterilization unit. Ensure you have a standard power outlet available in your cabinet space before installation.
The system is designed for a straightforward, 30-minute installation process that most homeowners can complete on their own. However, if you are uncomfortable working with under-sink plumbing or electrical connections, a professional plumber can easily handle the setup.
