No, if your toilet is not clogged, it doesn’t mean that there is no blockage anywhere. If your toilet is overflowing it means the drain pipe which is connected to the bottom of your toilet bowl has been clogged far from the bottom of your toilet.
Check these places for possible damage to fix your toilet overflowing problem, if it is not clogged:
The first place that you can check quickly is the toilet tank of your toilet. Might be it some parts become worn out or damaged and cause an overflowing problem in your toilet.
Check These Components For Troubleshooting:
The toilet fill valve manages the level of water in the tank, If it has some issue it overfills the toilet tank and causes overflowing.
The Flapper and Flush valve gasket are located at the bottom of your toilet tank. The flush valve creates an airtight sealing and prevents water flow after the flapper rests on it.
If anyone has an issue, it will create a problem in your toilet flush system.
Solution: Check the toilet fill valve, flapper, and flush valve gasket for possible damage and replace them to fix this problem.
Note: Replacing toilet tank components can solve the water leakage issue in your toilet bowl but, it will not solve the overflowing issue because, if leaked water is filled in your toilet bowl and doesn’t drain down it means your drain pipe is clogged beyond the toilet tank.
