Test Flush and Verify Repair

What happens here

After adjusting the flapper chain, allow the toilet tank to refill completely. Once the tank is full and the water stops running, perform a test flush. Observe the flapper's operation: it should open fully when the handle is pressed and then close completely and seal tightly against the flush valve seat as the tank empties. The water should then stop flowing into the bowl. The video shows the successful flush and the flapper closing properly, indicating that the continuous running issue has been resolved.

Goal: Confirm the toilet flushes correctly and the water stops running after the tank refills.
