Questions and answers
I want a draw of the water flow in this system
The water flow diagram for the GE GXRQ18NBN system is as follows:
1. Water enters the prefilter, where sand, silt, sediments, and chlorine are reduced.
2. Water leaves the prefilter and flows to the Reverse Osmosis (RO) cartridge.
3. Water enters the RO membrane, which filters out contaminants.
4. Clean water flows to the postfilter for final polishing.
5. Purified water is stored in a storage tank.
6. When the faucet is opened, water flows from the storage tank through the faucet.
7. Wastewater from the RO process is directed through the air gap faucet and into the drain.
This flow includes a gravity drain and a check valve for automatic shutoff.
