Buffalo Midi Sink & Basin Plunger 32cm. For: Sink & Basin These concertinaplungers (sometimes known as suction plungers)REALLY DO WORK at dislodging drains throughout the home. The concertina plastic construction in theunique bellow design, which is different to a traditional plunger, ensures that you are pushing water and air at the blockage, which means more force can be used to clear debris. They are flexible and very effective at clearing blockages inall types of sink, basin, bath or toilet.For maximum effect ensure the bellows are at least half full with water. Use a back and forth motion to push and pull the blockage. With a tight seal the backwards motion will actually suck the water away from the blockage. For very heavy blockages this is necessary in order to break it up and let the full impact of the force push it away. HEAVY DUTY, ERGONOMIC DESIGN,MORE FORCE TO CLEAR THE ISSUE, EASY TO USE AND TO CLEAN, EASY AND FLEXIBLETO STORE, REALLY GREAT PRICE!
