Buffalo Cooper Plunger.
• The traditional force cup plunger is a rubber force cup on the end of a wooden handle with a disc behind it.
• As the name suggests this plunger is used for forcing water down the drain, into the blockage and dislodging it.
• For maximum effect, with a tight seal and no air in the cup, a back and forth motion will create high and low pressure at the point of the blockage.
• This dual action may be needed several times to break up and release stubborn blockages from the sides of the drain.
• The long T-handle gives a good grip, and the flat rubber disc ensures a tight seal.
• Usually a series of short sharp pushes will release the blockage.
