When using a plunger to unclog a bath tub, toilet or sink, most people simply pump the plunger up and down 3-4 times and expect the water to whoosh down. To get better results, here are a few tips:
- Choose a plunger with a suctions cup large enough to cover the drain completely.
- Fill the clogged fixture with enough water to cover the dome of the plunger.
- Coat the rim of the plunger with petroleum jelly to ensure a tight seal.
- Block off all other water outlets, like the overflow or second drain in a double sink.
- Insert the plunger at an angle so that no air remains trapped under it.
- Use 15 to 20 forceful stokes, holding the plunger upright and pumping vigorously.
- Repeat this procedure 2 to 3 times before giving up.
