Personal experiences with the name Kiel: | Edit. My boyfriends name is Kiel pronounced Kyle because it is the name and spelling of a town in Germany that is a twin town to the one we live in Coventry.
A flapper is a rubber mechanism in your toilet tank that is the moving part of the flush valve, sealing water into the tank and allowing water to exit the tank when you flush. Flappers deteriorate over time as a result of in-tank cleaning products and chemicals used by utilities.
When you push the handle, the chain lifts the flapper valve (also called the stopper or tank ball) Water in the tank flows through the flush valve opening into the toilet bowl. The water from the tank forces waste water in the toilet bowl through the trap and into the main drain. Once the tank is empty, the flapper valve closes and the fill valve/ballcock refills the tank.
