Monument - 2161X Professional Power Plunger

The Monument Professional Power Plunger comes with 3 adaptors which should fit most shower, bath, basin, and bidet wastes.
When pumping the MON2161X unit in situ, it will build up pressure which is then activated via the trigger to blast away the blockage.
When the trigger is pulled quickly the compressed air is discharged, at once, causing a shock wave through the water to dislodge the blockage within the waste, even if it is past the trap, down the pipework and around several bends.
