Plungers work by sealing off the clogged area and forcing water through. The flat-bottomed plungers are ok, but don’t create the seal needed to really power through a clogged toilet. They are designed instead for use in sinks.
* While a toilet plunger is best, a sink plunger will work in a pinch.
* If your toilet is about to overflow, turn the metal handle at the back to shut off the water. Remember: Righty tighty!
* When the water level is very low, it can be difficult to create a seal with the plunger. In that case, pour a few glasses of water in the bowl.
