• A loose or damaged wax ring. The wax ring is a seal that sits between the toilet and the floor. It helps to create a watertight seal and prevent leaks. If the wax ring is loose or damaged, it can allow water to leak out from the bottom of the toilet.

It opens and closes to allow water to flow into the toilet bowl and to stop the flow of water when the toilet is flushed. If the flapper valve is faulty, it can allow water to leak out from the bottom of the tank.
