Do RO Systems send water down the drain?Updated 2 months ago
Some of the water that goes into an RO System does go to the drain. This drained water is carrying away filtered contaminants. The drained particles are too small to be caught by filters. They can only be safely disposed of by being flushed down the drain. The system only uses as much water as needed to dispose of impurities. The exact amount of water used changes with the quality of the water going into the system.
