The Monument 2161X Professional Power Plunger works with compressed air by means of pumping the plunger.
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 pipe-work and around several bends.
Three plunger adaptors are supplied that should fit most shower, bath, basin and bidet wastes-just place over the waste that is blocked and pump the lever to pressurise the unit.
It is also fitted with a pressure relief valve.
