Plunge the drain to dislodge the blockage

Place a cup plunger firmly over the drain opening, ensuring a tight seal. Fill the sink or tub with enough water to cover the plunger cup, then pump vigorously 15-20 times. The alternating pressure and suction forces water back and forth through the pipe, dislodging the clog.

Why It Works

The rapid push-pull action creates hydraulic pressure that physically shifts the blockage. Water acts as the force carrier, so a good seal and standing water are essential for the plunger to work.

Tips

• Use a cup plunger (flat bottom) for sinks and tubs, not a flange plunger (that is for toilets)
• Block the overflow hole with a wet rag to maintain pressure
• Apply petroleum jelly to the plunger rim for a better seal on smooth surfaces
