To ensure a tight seal, apply a liberal amount of petroleum jelly to the sealing edge of the cup.
Step 3 – Pull out flange
Pull out the flange from inside the cup
Step 4 – Submerge plunger
The plunger needs to be submerged in water to be effective. As a general rule, the cup should be at least half covered in water. If there is not enough water in the toilet, add some until the cup is covered, but do not flush the toilet as this may cause it to overflow
Step 5 – Angle entry
Angle the entry of the plunger into the water, this will eliminate any possible air lock.
Step 6 – Insert flange
Insert the flange of the plunger into the gulley
Step 7 – Ensure tight seal
Ensure the plunger has a tight seal with the gulley.
Step 8 – Press down firmly
Press down on the plunger handle firmly; this will flatten out the cup.
Step 9 – Begin plunging
Begin plunging, pulling up and down firmly on the handle, being careful to not break the connection between the sealing edge and gulley edge.
Step 10 – Work plunger
Work the plunger up and down a few times, with quick pulls and positive force, then give the plunger a forceful pull upwards to break the seal and lift up out of the water.
Step 11 – Check water level
Watch to see if the water level in the toilet alters. If the level goes down, flush the toilet. If the blockage is loosened or dislodged, the water will flush away down the drain.
In some cases, if the water level stays the same, the blockage may require a bit more work, so the process should be repeated.
