Use petroleum jelly on the sealing edge of the plunger (or cup washers) to help create a good seal. This will also prevent the rubber from drying and cracking which will enhance the life of the plunger.
Do not leave your plunger in direct sunlight as this will cause the rubber to crack and perish
Having trouble sealing off the over flow in a sink or bath? Then consider using a strip of strong adhesive tape over the over flow hole.
If you store your plunger outside and the rubber is cold, consider running the cup under warm water as warm soft rubber is more pliable and you will get a better seal.
Use hot water to fill the drain, toilet or sink up to the required level for plunging. Hot water can help to soften the blockage, making it easier to plunge and dislodge.
Avoid using chemicals to unblock a drain or gulley. Not only are they harmful to the environment, but chemicals can also splash back and cause injury to the person plunging.
