Perform Bucket Test for Confirmation

What happens here

To definitively confirm that the toilet clog is completely removed, perform the 'bucket test'. Locate a 5-gallon bucket and fill it with water, either from a nearby tub faucet as demonstrated or another water source. Once filled, carefully but quickly pour the entire contents of the 5-gallon bucket directly into the toilet bowl. This large volume of water creates a powerful surge that effectively tests the drain's capacity and integrity. If the toilet bowl drains all the water rapidly and completely without any backing up or gurgling, it signifies that the clog is fully cleared and the drain line is open. If the water struggles to drain or starts to back up, it indicates a remaining partial or full blockage.

Goal: Fill a 5-gallon bucket with water and quickly pour it into the toilet bowl to confirm complete clog removal.
