When the toilet is flushed, the water fill valve is activated and water begins to flow through the intake valve seat into the tank and refill tube. The refill tube's flow is directed into the overflow/drain tube, which empties into the bowl. The water entering the tank is retained in the tank and begins to accumulate until a predetermined level is reached. When the predetermined level is attained, the water intake valve closes and all flow into both tank and refill tube stops, until the next flush cycle is invoked. The water saver adapter prevents excess water from entering the overflow/drain tube during the flush and refill cycle by diverting a significant volume of water back into the water tank.
