Step 3 · Try a Plunger
Ensure there's enough water in the sink or tub to cover the bell of the plunger. Create a tight seal around the drain opening with the plunger. Give it a few firm up-and-down thrusts, then pull sharply upwards to break the seal. Repeat this process several times. If the water starts to drain, continue plunging until it flows freely. Flush with hot water afterward.
