How to use a cup plunger

A step by step guide to use a cup plunger

Step 1

Step 1 – Pick up plunger

Arm yourself with a cup plunger.

Step 2

Step 2 – Remove plugs

Remove any plugs or drain covers from the drain.

Seal off the sink over flow

Step 3 – Seal off over flow

Seal off any over flows. A damp towel or cloth can be used, or an alternative method would be to use a piece of tape (strong adhesive tape is best e.g. duct tape).

Step 3 apply to sealing edge

Step 4 – Ensure a tight seal

To ensure a tight seal, apply a liberal amount of petroleum jelly to the sealing edge of the cup.

The petroleum jelly increases suction to the applied surface and therefore improves the seal prior to plunging.
Submerge the plunger, at least half the cup needs to be covered.

Step 5 – Submerge plunger

The plunger needs to be at least half covered in water to be effective. If there is not enough water in the sink, add some until the cup is covered.

Step 4

Step 6 – Angle entry

Angle the entry of the plunger into the water; this will eliminate any possible air lock.

Step 5

Step 7 – Cover drain hole

Stand the plunger vertically, covering the drain hole, to ensure it has a tight seal. A gentle upward pull will test this; if the seal is tight, you will feel the cup stick to the surface.

Step 6

Step 8 – Press down firmly

Press down on the plunger handle firmly, this will flatten out the cup.

Step 7

Step 9 – Begin plunging

Begin plunging, pulling up and down firmly, being careful to not break the seal.

Step 8

Step 10 – Work plunger

Work the plunger up and down a few times, with quick pulls and force, then give the plunger a forceful pull upwards to break the seal and lift up out of the water.

Step 9

Step 11 – Check blockage

If the blockage is loosened or dislodged, the water will run away down the drain.

In some cases, the blockage may require a bit more work, so the process should then be repeated.
