Yes, backwashing does waste water—about 20 to 50 gallons per cycle. That sounds bad until you realize it only happens once a week.
Compare that to a running toilet that wastes 200 gallons a day. Suddenly, a clean filter seems like a water-saver.
Plus, some modern backwash filters have “eco” modes. They use smart valves to only flush when truly needed.
It’s like a filter with a brain. “I’ll decide when I’m full, thank you.”
